Dental Subluxation
Dental subluxation is a traumatic injury to the periodontal tissue in which the tooth has increased mobility (i.e., is loosened) but has not been displaced from its tooth socket. Cause High impact force during trauma causes damage to the periodontium and results swelling and bleeding from the gingival sulcus. Trauma also causes rupture of some periodontal fibres and this leads to loosening of the tooth. However, the force is not strong enough to cause displacement of the tooth from its socket. Sometimes, the trauma might cause pulpal damage and there is a minimal risk of pulpal necrosis, thus follow-up is essential. Diagnosis A tooth that has been subluxated shows symptoms of being tender to percussion (tapped using the end of the mirror) and tender to palpate around the area and sulcus (as it has been slightly mobilised yet remains undisplaced). Any sensitivity testing of the pulp may provide a negative response, in which case it is important to continue monitoring until a pu ...

Dentistry
Dentistry, also known as dental medicine and oral medicine, is the branch of medicine focused on the Human tooth, teeth, gums, and Human mouth, 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. 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. 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. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and dis ...

Dental Trauma
Dental trauma refers to trauma (injury) to the teeth and/or periodontium (gums, periodontal ligament, alveolar bone), and nearby soft tissues such as the lips, tongue, etc. The study of dental trauma is called dental traumatology.''Textbook and Color Atlas of Traumatic Injuries to the Teeth'', Fourth Edition, edited by Andreason J, Andreasen F, and Andersson L, Wiley-Blackwell, Oxford, UK, 2007 Types Dental injuries Dental injuries include: * Enamel infraction * Enamel fracture * Enamel-dentine fracture * Enamel-dentine fracture involving pulp exposure * Root fracture of tooth Periodontal injuries * Concussion (bruising) *Subluxation of the tooth (tooth knocked loose) * Luxation of the tooth (displaced) **Extrusive ** Intrusive **Lateral * Avulsion of the tooth (tooth knocked out) Injuries to supporting bone This injury involves the alveolar bone and may extend beyond the alveolus.

Tooth
A tooth (: teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tearing food, for defensive purposes, to intimidate other animals often including their own, or to carry prey or their young. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness that originate from the outermost embryonic germ layer, the ectoderm. The general structure of teeth is similar across the vertebrates, although there is considerable variation in their form and position. The teeth of mammals have deep roots, and this pattern is also found in some fish, and in crocodilians. In most teleost fish, however, the teeth are attached to the outer surface of the bone, while in lizards they are attached to the inner surface of the jaw by one side. In cartila ...

Health Technology Assessment (journal)
''Health Technology Assessment'' is a weekly peer-reviewed open access medical journal published by the National Institute for Health and Care Research (NIHR), a research partner of the United Kingdom National Health Service. It publishes research on the evaluations of health technologies, their effectiveness, cost and broader impact. The journal was established in 1997 and the editor-in-chief is John Powell (NIHR). According to the ''Journal Citation Reports'', the journal has a 2015 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a type of journal ranking. Journals with higher impact factor values are considered more prestigious or important within their field. The Impact Factor of a journa ... of 4.058. The journal, along with four others, is part of the NIHR Journals Library.

Chlorhexidine
Chlorhexidine is a disinfectant and antiseptic which is used for skin disinfection before surgery and to disinfect surgical instruments. It is also used for cleaning wounds, preventing dental plaque, treating yeast infections of the mouth, and to keep urinary catheters from blocking. It is used as a liquid or a powder. It is commonly used in Ionic compound, salt form, either the gluconate or the acetate. Side effects may include skin irritation, Human tooth, tooth discoloration, and allergic reactions, although, apart from discoloration, the risk appears to be the same as that for povidone-iodine. Chlorhexidine rinse is also known to have a bitter metallic aftertaste. Rinsing with water is not recommended as it is known to increase the bitterness. It may cause eye problems if direct contact occurs. Use in pregnancy appears to be safe. Chlorhexidine may come mixed in ethanol, alcohol, water, or surfactant solution. It is effective against a range of microorganisms, but does not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subluxation
A subluxation is an incomplete or partial dislocation of a joint or organ. According to the World Health Organization, a subluxation is a "significant structural displacement" and is therefore visible on static imaging studies, such as X-rays. Unlike real subluxations, the pseudoscientific concept of a chiropractic "vertebral subluxation" may or may not be visible on x-rays. The term is used in the fields of medicine, dentistry, and chiropractic. There is no scientific evidence for the existence of chiropractic subluxations or proof they or their treatment have any effects on health. Medical Joints A subluxation of a joint is where a connecting bone is partially out of the joint. In contrast to a luxation, which is a complete separation of the joint, a subluxation often returns to its normal position without additional help from a health professional. An example of a joint subluxation is a nursemaid's elbow, which is the subluxation of the head of the radius from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
