Regular Adjustments and Why They Matter

Regular Adjustments and Why They Matter

Types of Malocclusions: Overview of common types such as overbite, underbite, and crossbite in pediatric patients.

In the journey towards achieving a perfect smile, orthodontic care plays a crucial role, and regular adjustments are the unsung heroes of this process. These adjustments, often scheduled every few weeks, are vital for several reasons, ensuring the treatment remains on track and effective.


Firstly, orthodontic treatments, whether involving braces or aligners, work by gradually shifting teeth into their desired positions. Regular adjustments allow orthodontists to monitor this progress closely. Jaw growth issues are easier to correct at an early age Youth orthodontic correction hospital. During these visits, they can tweak the forces applied to the teeth, ensuring each tooth moves as planned. Without these adjustments, the treatment could stagnate or even go off course, prolonging the time needed to achieve the desired results.


Secondly, regular check-ups enable the orthodontist to address any issues promptly. Braces and aligners can sometimes cause discomfort or irritation, and adjustments provide an opportunity to alleviate these problems. For instance, wires might need to be clipped or bands adjusted to prevent sores or other discomforts. This not only improves the patient's experience but also encourages adherence to the treatment plan.


Moreover, these visits are essential for maintaining the health of the teeth and gums. Orthodontic appliances can make oral hygiene more challenging, increasing the risk of plaque buildup and gum disease. Regular adjustments include professional cleanings and assessments, helping to keep the mouth healthy throughout the treatment.


Lastly, the psychological aspect cannot be overlooked. Seeing progress, no matter how small, can be incredibly motivating for patients. Regular adjustments provide tangible evidence of movement and improvement, boosting morale and commitment to the treatment.


In essence, regular adjustments in orthodontic care are fundamental to the success of the treatment. They ensure the teeth move efficiently and correctly, maintain oral health, address any discomforts, and keep patients motivated. Skipping these crucial visits can compromise the entire process, underscoring their importance in the quest for a healthier, more beautiful smile.

Regular adjustments are a cornerstone of effective treatment outcomes across various fields, from healthcare to personal development. These adjustments ensure that strategies and interventions remain relevant and responsive to changing conditions, thereby enhancing their efficacy. Let's delve into why regular adjustments matter and how they contribute to successful outcomes.


First and foremost, regular adjustments allow for the continuous monitoring and evaluation of progress. In healthcare, for instance, a patient's treatment plan might need to be altered based on their response to medication or changes in their symptoms. By regularly reviewing and adjusting the treatment, healthcare providers can optimize the patient's recovery process, ensuring that they receive the most beneficial care at every stage.


In the realm of personal development, regular adjustments are equally crucial. Whether it's a fitness regimen or a learning plan, individuals often encounter new challenges or reach different stages of their goals. Regularly assessing progress and making necessary tweaks-such as increasing workout intensity or modifying study techniques-helps maintain momentum and keeps individuals on track towards achieving their objectives.


Moreover, regular adjustments foster adaptability, a key component in navigating the unpredictability of life. In business, for example, market conditions can shift rapidly, necessitating changes in strategy to stay competitive. Companies that regularly adjust their approaches based on market feedback and performance metrics are better positioned to thrive amidst uncertainty.


The process of making regular adjustments also encourages a culture of continuous improvement. By consistently reflecting on what works and what doesn't, individuals and organizations can identify areas for enhancement and implement changes that lead to better outcomes. This iterative approach not only drives progress but also promotes a mindset of resilience and innovation.


In conclusion, regular adjustments are vital for ensuring that treatment plans, personal goals, and business strategies remain effective and responsive to change. By fostering continuous monitoring, adaptability, and a commitment to improvement, regular adjustments play a pivotal role in achieving successful outcomes across various domains.

Early Detection and Diagnosis: The importance of regular dental check-ups for identifying malocclusions in children.

Orthodontists play a crucial role in ensuring that patients achieve the best possible outcomes from their orthodontic treatments. Regular adjustments are a fundamental part of this process, and they matter significantly because they help maintain the progress and effectiveness of the treatment.


When patients embark on their orthodontic journey, whether it involves braces, aligners, or other devices, the orthodontist's expertise becomes indispensable. Regular check-ups, typically scheduled every 4 to 6 weeks, allow the orthodontist to closely monitor the movement of teeth and the overall progress of the treatment. During these visits, the orthodontist can make necessary adjustments to the orthodontic appliances, ensuring they continue to apply the correct pressure and direction needed to shift teeth into their desired positions.


These adjustments are not just routine; they are critical interventions. For instance, if a bracket becomes loose or a wire needs tightening, the orthodontist can address these issues promptly to prevent any setbacks. Moreover, these visits provide an opportunity for the orthodontist to assess the patient's oral health and hygiene, offering guidance on how to care for their teeth and appliances properly.


The importance of these regular adjustments cannot be overstated. They ensure that the treatment stays on track, minimizing the total time required to achieve the desired results. Without them, patients might experience delays, discomfort, or even complications that could necessitate more extensive interventions later on.


In essence, the role of orthodontists in monitoring progress and making necessary adjustments is pivotal. It underscores the collaborative nature of orthodontic treatment, where the patient's commitment to regular visits and the orthodontist's expertise work hand in hand to create a successful outcome. Regular adjustments matter because they are the fine-tuning that keeps the journey towards a healthier, more beautiful smile on course.

Orthodontic Treatment Options for Kids: Discussing braces, aligners, and other corrective measures suitable for young patients.

Missing regular adjustment appointments can have significant repercussions on your overall well-being and the effectiveness of your treatment plan. When you skip these crucial check-ins, you're not just missing a date on your calendar; you're potentially jeopardizing the progress you've made and the goals you're trying to achieve.


First and foremost, regular adjustments are essential for maintaining the alignment and functionality of your body. Whether it's chiropractic care, orthodontic treatment, or another form of therapy, these appointments are designed to keep you on track and ensure that your body is responding as expected. When you miss an adjustment, you risk allowing minor issues to develop into more significant problems that could require more intensive intervention down the line.


Moreover, skipping appointments can lead to a loss of momentum in your treatment. Just like a garden needs regular watering to thrive, your body needs consistent care to heal and improve. When you miss an appointment, you're essentially hitting the pause button on your progress, which can be frustrating and disheartening.


Another potential consequence of missing regular adjustments is the financial impact. Many treatment plans are structured to be most effective and cost-efficient when followed consistently. When you miss appointments, you may need additional sessions to catch up, which can increase the overall cost of your care.


Lastly, and perhaps most importantly, missing regular adjustments can affect your mental and emotional well-being. When you're committed to a treatment plan, it's not just about the physical benefits; it's also about the sense of progress, hope, and empowerment that comes with taking charge of your health. Missing appointments can lead to feelings of guilt, disappointment, and a loss of motivation, which can be detrimental to your overall mental health.


In conclusion, while life can sometimes get in the way of our best intentions, it's crucial to prioritize regular adjustment appointments. By attending these sessions consistently, you're not only investing in your physical health but also in your mental and emotional well-being. Remember, your health is worth the effort, and the potential consequences of missing appointments are simply too significant to ignore.

The Role of Parents in Orthodontic Care: How parents can support their child's orthodontic treatment and encourage good oral habits.

Ensuring that your kids attend regular orthodontic adjustments is crucial for the success of their treatment. These appointments are not just routine check-ups; they are essential steps in the journey towards a healthier, more beautiful smile. Here are some tips for parents to help make sure their children keep up with these important visits.


First and foremost, it's important to set a positive tone about orthodontic care. Explain to your child why these adjustments are necessary and how they contribute to the end goal of straighter teeth and a better bite. You can make it a fun and educational experience by showing them before-and-after photos or even letting them pick out colorful bands for their braces.


Scheduling is another key aspect. Make sure to book these appointments well in advance and try to choose times that work well with your family's routine. If possible, opt for after-school slots or times when your child is less likely to be tired or hungry. It can also help to set reminders on your phone or calendar so that these appointments don't slip through the cracks.


Incentives can be a great way to encourage your child to look forward to their orthodontic visits. Consider setting up a reward system where they earn points or small treats for attending their appointments and following their orthodontist's instructions. This can make the process feel more like a game and less like a chore.


Lastly, it's important to be supportive and understanding. Orthodontic adjustments can sometimes be uncomfortable, and your child might feel anxious or frustrated. Be there to listen to their concerns and reassure them that these feelings are normal and temporary. Offer hugs, praise, and encouragement, and remind them that each visit brings them closer to the end of their treatment.


By setting a positive tone, scheduling wisely, using incentives, and providing emotional support, you can help ensure that your child attends their regular orthodontic adjustments. These visits are a vital part of their treatment, and your involvement can make all the difference in achieving the best possible results.

An oral surgeon and dental assistant removing a wisdom tooth

Dentistry, also known as dental medicine and oral medicine, is the branch of medicine focused on the teeth, gums, and mouth. It consists of the study, diagnosis, prevention, management, and treatment of diseases, disorders, and conditions of the mouth, most commonly focused on dentition (the development and arrangement of teeth) as well as the oral mucosa.[2] Dentistry may also encompass other aspects of the craniofacial complex including the temporomandibular joint. The practitioner is called a dentist.

The history of dentistry is almost as ancient as the history of humanity and civilization, with the earliest evidence dating from 7000 BC to 5500 BC.[3] Dentistry is thought to have been the first specialization in medicine which has gone on to develop its own accredited degree with its own specializations.[4] Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and diseases) for which reason the two terms are used interchangeably in certain regions. However, some specialties such as oral and maxillofacial surgery (facial reconstruction) may require both medical and dental degrees to accomplish. In European history, dentistry is considered to have stemmed from the trade of barber surgeons.[5]

Dental treatments are carried out by a dental team, which often consists of a dentist and dental auxiliaries (such as dental assistants, dental hygienists, dental technicians, and dental therapists). Most dentists either work in private practices (primary care), dental hospitals, or (secondary care) institutions (prisons, armed forces bases, etc.).

The modern movement of evidence-based dentistry calls for the use of high-quality scientific research and evidence to guide decision-making such as in manual tooth conservation, use of fluoride water treatment and fluoride toothpaste, dealing with oral diseases such as tooth decay and periodontitis, as well as systematic diseases such as osteoporosis, diabetes, celiac disease, cancer, and HIV/AIDS which could also affect the oral cavity. Other practices relevant to evidence-based dentistry include radiology of the mouth to inspect teeth deformity or oral malaises, haematology (study of blood) to avoid bleeding complications during dental surgery, cardiology (due to various severe complications arising from dental surgery with patients with heart disease), etc.

Terminology

[edit]

The term dentistry comes from dentist, which comes from French dentiste, which comes from the French and Latin words for tooth.[6] The term for the associated scientific study of teeth is odontology (from Ancient Greek: á½€δούς, romanized: odoús, lit. 'tooth') – the study of the structure, development, and abnormalities of the teeth.

Dental treatment

[edit]

Dentistry usually encompasses practices related to the oral cavity.[7] According to the World Health Organization, oral diseases are major public health problems due to their high incidence and prevalence across the globe, with the disadvantaged affected more than other socio-economic groups.[8]

The majority of dental treatments are carried out to prevent or treat the two most common oral diseases which are dental caries (tooth decay) and periodontal disease (gum disease or pyorrhea). Common treatments involve the restoration of teeth, extraction or surgical removal of teeth, scaling and root planing, endodontic root canal treatment, and cosmetic dentistry[9]

By nature of their general training, dentists, without specialization can carry out the majority of dental treatments such as restorative (fillings, crowns, bridges), prosthetic (dentures), endodontic (root canal) therapy, periodontal (gum) therapy, and extraction of teeth, as well as performing examinations, radiographs (x-rays), and diagnosis. Dentists can also prescribe medications used in the field such as antibiotics, sedatives, and any other drugs used in patient management. Depending on their licensing boards, general dentists may be required to complete additional training to perform sedation, dental implants, etc.

Irreversible enamel defects caused by an untreated celiac disease. They may be the only clue to its diagnosis, even in absence of gastrointestinal symptoms, but are often confused with fluorosis, tetracycline discoloration, acid reflux or other causes.[10][11][12] The National Institutes of Health include a dental exam in the diagnostic protocol of celiac disease.[10]

Dentists also encourage the prevention of oral diseases through proper hygiene and regular, twice or more yearly, checkups for professional cleaning and evaluation. Oral infections and inflammations may affect overall health and conditions in the oral cavity may be indicative of systemic diseases, such as osteoporosis, diabetes, celiac disease or cancer.[7][10][13][14] Many studies have also shown that gum disease is associated with an increased risk of diabetes, heart disease, and preterm birth. The concept that oral health can affect systemic health and disease is referred to as "oral-systemic health".

John M. Harris started the world's first dental school in Bainbridge, Ohio, and helped to establish dentistry as a health profession. It opened on 21 February 1828, and today is a dental museum.[15] The first dental college, Baltimore College of Dental Surgery, opened in Baltimore, Maryland, US in 1840. The second in the United States was the Ohio College of Dental Surgery, established in Cincinnati, Ohio, in 1845.[16] The Philadelphia College of Dental Surgery followed in 1852.[17] In 1907, Temple University accepted a bid to incorporate the school.

Studies show that dentists that graduated from different countries,[18] or even from different dental schools in one country,[19] may make different clinical decisions for the same clinical condition. For example, dentists that graduated from Israeli dental schools may recommend the removal of asymptomatic impacted third molar (wisdom teeth) more often than dentists that graduated from Latin American or Eastern European dental schools.[20]

In the United Kingdom, the first dental schools, the London School of Dental Surgery and the Metropolitan School of Dental Science, both in London, opened in 1859.[21] The British Dentists Act of 1878 and the 1879 Dentists Register limited the title of "dentist" and "dental surgeon" to qualified and registered practitioners.[22][23] However, others could legally describe themselves as "dental experts" or "dental consultants".[24] The practice of dentistry in the United Kingdom became fully regulated with the 1921 Dentists Act, which required the registration of anyone practising dentistry.[25] The British Dental Association, formed in 1880 with Sir John Tomes as president, played a major role in prosecuting dentists practising illegally.[22] Dentists in the United Kingdom are now regulated by the General Dental Council.

In many countries, dentists usually complete between five and eight years of post-secondary education before practising. Though not mandatory, many dentists choose to complete an internship or residency focusing on specific aspects of dental care after they have received their dental degree. In a few countries, to become a qualified dentist one must usually complete at least four years of postgraduate study;[26] Dental degrees awarded around the world include the Doctor of Dental Surgery (DDS) and Doctor of Dental Medicine (DMD) in North America (US and Canada), and the Bachelor of Dental Surgery/Baccalaureus Dentalis Chirurgiae (BDS, BDent, BChD, BDSc) in the UK and current and former British Commonwealth countries.

All dentists in the United States undergo at least three years of undergraduate studies, but nearly all complete a bachelor's degree. This schooling is followed by four years of dental school to qualify as a "Doctor of Dental Surgery" (DDS) or "Doctor of Dental Medicine" (DMD). Specialization in dentistry is available in the fields of Anesthesiology, Dental Public Health, Endodontics, Oral Radiology, Oral and Maxillofacial Surgery, Oral Medicine, Orofacial Pain, Pathology, Orthodontics, Pediatric Dentistry (Pedodontics), Periodontics, and Prosthodontics.[27]

Specialties

[edit]

Some dentists undertake further training after their initial degree in order to specialize. Exactly which subjects are recognized by dental registration bodies varies according to location. Examples include:

  • Anesthesiology[28] – The specialty of dentistry that deals with the advanced use of general anesthesia, sedation and pain management to facilitate dental procedures.
  • Cosmetic dentistry – Focuses on improving the appearance of the mouth, teeth and smile.
  • Dental public health – The study of epidemiology and social health policies relevant to oral health.
  • Endodontics (also called endodontology) – Root canal therapy and study of diseases of the dental pulp and periapical tissues.
  • Forensic odontology – The gathering and use of dental evidence in law. This may be performed by any dentist with experience or training in this field. The function of the forensic dentist is primarily documentation and verification of identity.
  • Geriatric dentistry or geriodontics – The delivery of dental care to older adults involving the diagnosis, prevention, and treatment of problems associated with normal aging and age-related diseases as part of an interdisciplinary team with other health care professionals.
  • Oral and maxillofacial pathology – The study, diagnosis, and sometimes the treatment of oral and maxillofacial related diseases.
  • Oral and maxillofacial radiology – The study and radiologic interpretation of oral and maxillofacial diseases.
  • Oral and maxillofacial surgery (also called oral surgery) – Extractions, implants, and surgery of the jaws, mouth and face.[nb 2]
  • Oral biology – Research in dental and craniofacial biology
  • Oral Implantology – The art and science of replacing extracted teeth with dental implants.
  • Oral medicine – The clinical evaluation and diagnosis of oral mucosal diseases
  • Orthodontics and dentofacial orthopedics – The straightening of teeth and modification of midface and mandibular growth.
  • Pediatric dentistry (also called pedodontics) – Dentistry for children
  • Periodontology (also called periodontics) – The study and treatment of diseases of the periodontium (non-surgical and surgical) as well as placement and maintenance of dental implants
  • Prosthodontics (also called prosthetic dentistry) – Dentures, bridges and the restoration of implants.
    • Some prosthodontists super-specialize in maxillofacial prosthetics, which is the discipline originally concerned with the rehabilitation of patients with congenital facial and oral defects such as cleft lip and palate or patients born with an underdeveloped ear (microtia). Today, most maxillofacial prosthodontists return function and esthetics to patients with acquired defects secondary to surgical removal of head and neck tumors, or secondary to trauma from war or motor vehicle accidents.
  • Special needs dentistry (also called special care dentistry) – Dentistry for those with developmental and acquired disabilities.
  • Sports dentistry – the branch of sports medicine dealing with prevention and treatment of dental injuries and oral diseases associated with sports and exercise.[29] The sports dentist works as an individual consultant or as a member of the Sports Medicine Team.
  • Veterinary dentistry – The field of dentistry applied to the care of animals. It is a specialty of veterinary medicine.[30][31]

History

[edit]

Farmer at the dentist, Johann Liss, c. 1616–17

Tooth decay was low in pre-agricultural societies, but the advent of farming society about 10,000 years ago correlated with an increase in tooth decay (cavities).[32] An infected tooth from Italy partially cleaned with flint tools, between 13,820 and 14,160 years old, represents the oldest known dentistry,[33] although a 2017 study suggests that 130,000 years ago the Neanderthals already used rudimentary dentistry tools.[34] In Italy evidence dated to the Paleolithic, around 13,000 years ago, points to bitumen used to fill a tooth[35] and in Neolithic Slovenia, 6500 years ago, beeswax was used to close a fracture in a tooth.[36] The Indus valley has yielded evidence of dentistry being practised as far back as 7000 BC, during the Stone Age.[37] The Neolithic site of Mehrgarh (now in Pakistan's south western province of Balochistan) indicates that this form of dentistry involved curing tooth related disorders with bow drills operated, perhaps, by skilled bead-crafters.[3] The reconstruction of this ancient form of dentistry showed that the methods used were reliable and effective.[38] The earliest dental filling, made of beeswax, was discovered in Slovenia and dates from 6500 years ago.[39] Dentistry was practised in prehistoric Malta, as evidenced by a skull which had a dental abscess lanced from the root of a tooth dating back to around 2500 BC.[40]

An ancient Sumerian text describes a "tooth worm" as the cause of dental caries.[41] Evidence of this belief has also been found in ancient India, Egypt, Japan, and China. The legend of the worm is also found in the Homeric Hymns,[42] and as late as the 14th century AD the surgeon Guy de Chauliac still promoted the belief that worms cause tooth decay.[43]

Recipes for the treatment of toothache, infections and loose teeth are spread throughout the Ebers Papyrus, Kahun Papyri, Brugsch Papyrus, and Hearst papyrus of Ancient Egypt.[44] The Edwin Smith Papyrus, written in the 17th century BC but which may reflect previous manuscripts from as early as 3000 BC, discusses the treatment of dislocated or fractured jaws.[44][45] In the 18th century BC, the Code of Hammurabi referenced dental extraction twice as it related to punishment.[46] Examination of the remains of some ancient Egyptians and Greco-Romans reveals early attempts at dental prosthetics.[47] However, it is possible the prosthetics were prepared after death for aesthetic reasons.[44]

Ancient Greek scholars Hippocrates and Aristotle wrote about dentistry, including the eruption pattern of teeth, treating decayed teeth and gum disease, extracting teeth with forceps, and using wires to stabilize loose teeth and fractured jaws.[48] Use of dental appliances, bridges and dentures was applied by the Etruscans in northern Italy, from as early as 700 BC, of human or other animal teeth fastened together with gold bands.[49][50][51] The Romans had likely borrowed this technique by the 5th century BC.[50][52] The Phoenicians crafted dentures during the 6th–4th century BC, fashioning them from gold wire and incorporating two ivory teeth.[53] In ancient Egypt, Hesy-Ra is the first named "dentist" (greatest of the teeth). The Egyptians bound replacement teeth together with gold wire. Roman medical writer Cornelius Celsus wrote extensively of oral diseases as well as dental treatments such as narcotic-containing emollients and astringents.[54] The earliest dental amalgams were first documented in a Tang dynasty medical text written by the Chinese physician Su Kung in 659, and appeared in Germany in 1528.[55][56]

During the Islamic Golden Age Dentistry was discussed in several famous books of medicine such as The Canon in medicine written by Avicenna and Al-Tasreef by Al-Zahrawi who is considered the greatest surgeon of the Middle Ages,[57] Avicenna said that jaw fracture should be reduced according to the occlusal guidance of the teeth; this principle is still valid in modern times. Al-Zahrawi invented over 200 surgical tools that resemble the modern kind.[58]

Historically, dental extractions have been used to treat a variety of illnesses. During the Middle Ages and throughout the 19th century, dentistry was not a profession in itself, and often dental procedures were performed by barbers or general physicians. Barbers usually limited their practice to extracting teeth which alleviated pain and associated chronic tooth infection. Instruments used for dental extractions date back several centuries. In the 14th century, Guy de Chauliac most probably invented the dental pelican[59] (resembling a pelican's beak) which was used to perform dental extractions up until the late 18th century. The pelican was replaced by the dental key[60] which, in turn, was replaced by modern forceps in the 19th century.[61]

The first book focused solely on dentistry was the "Artzney Buchlein" in 1530,[48] and the first dental textbook written in English was called "Operator for the Teeth" by Charles Allen in 1685.[23]

In the United Kingdom, there was no formal qualification for the providers of dental treatment until 1859 and it was only in 1921 that the practice of dentistry was limited to those who were professionally qualified. The Royal Commission on the National Health Service in 1979 reported that there were then more than twice as many registered dentists per 10,000 population in the UK than there were in 1921.[62]

Modern dentistry

[edit]
A microscopic device used in dental analysis, c. 1907

It was between 1650 and 1800 that the science of modern dentistry developed. The English physician Thomas Browne in his A Letter to a Friend (c. 1656 pub. 1690) made an early dental observation with characteristic humour:

The Egyptian Mummies that I have seen, have had their Mouths open, and somewhat gaping, which affordeth a good opportunity to view and observe their Teeth, wherein 'tis not easie to find any wanting or decayed: and therefore in Egypt, where one Man practised but one Operation, or the Diseases but of single Parts, it must needs be a barren Profession to confine unto that of drawing of Teeth, and little better than to have been Tooth-drawer unto King Pyrrhus, who had but two in his Head.

The French surgeon Pierre Fauchard became known as the "father of modern dentistry". Despite the limitations of the primitive surgical instruments during the late 17th and early 18th century, Fauchard was a highly skilled surgeon who made remarkable improvisations of dental instruments, often adapting tools from watchmakers, jewelers and even barbers, that he thought could be used in dentistry. He introduced dental fillings as treatment for dental cavities. He asserted that sugar-derived acids like tartaric acid were responsible for dental decay, and also suggested that tumors surrounding the teeth and in the gums could appear in the later stages of tooth decay.[63][64]

Fauchard was the pioneer of dental prosthesis, and he invented many methods to replace lost teeth. He suggested that substitutes could be made from carved blocks of ivory or bone. He also introduced dental braces, although they were initially made of gold, he discovered that the teeth position could be corrected as the teeth would follow the pattern of the wires. Waxed linen or silk threads were usually employed to fasten the braces. His contributions to the world of dental science consist primarily of his 1728 publication Le chirurgien dentiste or The Surgeon Dentist. The French text included "basic oral anatomy and function, dental construction, and various operative and restorative techniques, and effectively separated dentistry from the wider category of surgery".[63][64]

A modern dentist's chair

After Fauchard, the study of dentistry rapidly expanded. Two important books, Natural History of Human Teeth (1771) and Practical Treatise on the Diseases of the Teeth (1778), were published by British surgeon John Hunter. In 1763, he entered into a period of collaboration with the London-based dentist James Spence. He began to theorise about the possibility of tooth transplants from one person to another. He realised that the chances of a successful tooth transplant (initially, at least) would be improved if the donor tooth was as fresh as possible and was matched for size with the recipient. These principles are still used in the transplantation of internal organs. Hunter conducted a series of pioneering operations, in which he attempted a tooth transplant. Although the donated teeth never properly bonded with the recipients' gums, one of Hunter's patients stated that he had three which lasted for six years, a remarkable achievement for the period.[65]

Major advances in science were made in the 19th century, and dentistry evolved from a trade to a profession. The profession came under government regulation by the end of the 19th century. In the UK, the Dentist Act was passed in 1878 and the British Dental Association formed in 1879. In the same year, Francis Brodie Imlach was the first ever dentist to be elected President of the Royal College of Surgeons (Edinburgh), raising dentistry onto a par with clinical surgery for the first time.[66]

Hazards in modern dentistry

[edit]

Long term occupational noise exposure can contribute to permanent hearing loss, which is referred to as noise-induced hearing loss (NIHL) and tinnitus. Noise exposure can cause excessive stimulation of the hearing mechanism, which damages the delicate structures of the inner ear.[67] NIHL can occur when an individual is exposed to sound levels above 90 dBA according to the Occupational Safety and Health Administration (OSHA). Regulations state that the permissible noise exposure levels for individuals is 90 dBA.[68] For the National Institute for Occupational Safety and Health (NIOSH), exposure limits are set to 85 dBA. Exposures below 85 dBA are not considered to be hazardous. Time limits are placed on how long an individual can stay in an environment above 85 dBA before it causes hearing loss. OSHA places that limitation at 8 hours for 85 dBA. The exposure time becomes shorter as the dBA level increases.

Within the field of dentistry, a variety of cleaning tools are used including piezoelectric and sonic scalers, and ultrasonic scalers and cleaners.[69] While a majority of the tools do not exceed 75 dBA,[70] prolonged exposure over many years can lead to hearing loss or complaints of tinnitus.[71] Few dentists have reported using personal hearing protective devices,[72][73] which could offset any potential hearing loss or tinnitus.

Evidence-based dentistry

[edit]

There is a movement in modern dentistry to place a greater emphasis on high-quality scientific evidence in decision-making. Evidence-based dentistry (EBD) uses current scientific evidence to guide decisions. It is an approach to oral health that requires the application and examination of relevant scientific data related to the patient's oral and medical health. Along with the dentist's professional skill and expertise, EBD allows dentists to stay up to date on the latest procedures and patients to receive improved treatment. A new paradigm for medical education designed to incorporate current research into education and practice was developed to help practitioners provide the best care for their patients.[74] It was first introduced by Gordon Guyatt and the Evidence-Based Medicine Working Group at McMaster University in Ontario, Canada in the 1990s. It is part of the larger movement toward evidence-based medicine and other evidence-based practices, especially since a major part of dentistry involves dealing with oral and systemic diseases. Other issues relevant to the dental field in terms of evidence-based research and evidence-based practice include population oral health, dental clinical practice, tooth morphology etc.

Ethical and medicolegal issues

[edit]

Dentistry is unique in that it requires dental students to have competence-based clinical skills that can only be acquired through supervised specialized laboratory training and direct patient care.[75] This necessitates the need for a scientific and professional basis of care with a foundation of extensive research-based education.[76] According to some experts, the accreditation of dental schools can enhance the quality and professionalism of dental education.[77][78]

Notes

[edit]
  1. ^ Whether Dentists are referred to as "Doctor" is subject to geographic variation. For example, they are called "Doctor" in the US. In the UK, dentists have traditionally been referred to as "Mister" as they identified themselves with barber surgeons more than physicians (as do surgeons in the UK, see Surgeon#Titles). However more UK dentists now refer to themselves as "Doctor", although this was considered to be potentially misleading by the British public in a single report (see Costley and Fawcett 2010).

Human lower jaw viewed from the left

The jaws are a pair of opposable articulated structures at the entrance of the mouth, typically used for grasping and manipulating food. The term jaws is also broadly applied to the whole of the structures constituting the vault of the mouth and serving to open and close it and is part of the body plan of humans and most animals.

Arthropods

[edit]
The mandibles of a bull ant

In arthropods, the jaws are chitinous and oppose laterally, and may consist of mandibles or chelicerae. These jaws are often composed of numerous mouthparts. Their function is fundamentally for food acquisition, conveyance to the mouth, and/or initial processing (mastication or chewing). Many mouthparts and associate structures (such as pedipalps) are modified legs.

Vertebrates

[edit]

In most vertebrates, the jaws are bony or cartilaginous and oppose vertically, comprising an upper jaw and a lower jaw. The vertebrate jaw is derived from the most anterior two pharyngeal arches supporting the gills, and usually bears numerous teeth.

Fish

[edit]
Moray eels have two sets of jaws: the oral jaws that capture prey and the pharyngeal jaws that advance into the mouth and move prey from the oral jaws to the esophagus for swallowing.

The vertebrate jaw probably originally evolved in the Silurian period and appeared in the Placoderm fish which further diversified in the Devonian. The two most anterior pharyngeal arches are thought to have become the jaw itself and the hyoid arch, respectively. The hyoid system suspends the jaw from the braincase of the skull, permitting great mobility of the jaws. While there is no fossil evidence directly to support this theory, it makes sense in light of the numbers of pharyngeal arches that are visible in extant jawed vertebrates (the Gnathostomes), which have seven arches, and primitive jawless vertebrates (the Agnatha), which have nine.

The original selective advantage offered by the jaw may not be related to feeding, but rather to increased respiration efficiency.[1] The jaws were used in the buccal pump (observable in modern fish and amphibians) that pumps water across the gills of fish or air into the lungs in the case of amphibians. Over evolutionary time the more familiar use of jaws (to humans), in feeding, was selected for and became a very important function in vertebrates. Many teleost fish have substantially modified jaws for suction feeding and jaw protrusion, resulting in highly complex jaws with dozens of bones involved.[2]

Amphibians, reptiles, and birds

[edit]

The jaw in tetrapods is substantially simplified compared to fish. Most of the upper jaw bones (premaxilla, maxilla, jugal, quadratojugal, and quadrate) have been fused to the braincase, while the lower jaw bones (dentary, splenial, angular, surangular, and articular) have been fused together into a unit called the mandible. The jaw articulates via a hinge joint between the quadrate and articular. The jaws of tetrapods exhibit varying degrees of mobility between jaw bones. Some species have jaw bones completely fused, while others may have joints allowing for mobility of the dentary, quadrate, or maxilla. The snake skull shows the greatest degree of cranial kinesis, which allows the snake to swallow large prey items.

Mammals

[edit]

In mammals, the jaws are made up of the mandible (lower jaw) and the maxilla (upper jaw). In the ape, there is a reinforcement to the lower jaw bone called the simian shelf. In the evolution of the mammalian jaw, two of the bones of the jaw structure (the articular bone of the lower jaw, and quadrate) were reduced in size and incorporated into the ear, while many others have been fused together.[3] As a result, mammals show little or no cranial kinesis, and the mandible is attached to the temporal bone by the temporomandibular joints. Temporomandibular joint dysfunction is a common disorder of these joints, characterized by pain, clicking and limitation of mandibular movement.[4] Especially in the therian mammal, the premaxilla that constituted the anterior tip of the upper jaw in reptiles has reduced in size; and most of the mesenchyme at the ancestral upper jaw tip has become a protruded mammalian nose.[5]

Sea urchins

[edit]

Sea urchins possess unique jaws which display five-part symmetry, termed the Aristotle's lantern. Each unit of the jaw holds a single, perpetually growing tooth composed of crystalline calcium carbonate.

Frequently Asked Questions

Regular adjustments are crucial because they allow the orthodontist to monitor progress, make necessary tweaks to the braces or aligners, and ensure that the teeth are moving as planned. This helps in achieving the desired alignment and bite correction efficiently and effectively.
Typically, orthodontic adjustments are scheduled every 4 to 8 weeks, depending on the specific treatment plan and the type of orthodontic appliance used. Your orthodontist will determine the best frequency for your childs needs.
Missing or delaying adjustments can prolong the treatment time and may compromise the final results. Consistent adjustments are essential for maintaining the momentum of tooth movement and ensuring that the treatment stays on track. Delays can lead to setbacks and may require additional interventions to correct.
