A pericoronal abscess may occur during an acute episode of pericoronitis in the soft tissue surrounding the crown of a partially or fully erupted tooth, usually around a partially erupted and impacted mandibular third molar (lower wisdom tooth). Periodontal abscesses are the 3rd most common dental emergency, [13] occurring either as acute ...
Pericoronitis is caused by an accumulation of bacteria and debris beneath the operculum, or by mechanical trauma (e.g. biting the operculum with the opposing tooth). [3] Pericoronitis is often associated with partially erupted and impacted mandibular third molars (lower wisdom teeth), [4] often occurring at the age of wisdom tooth eruption (15-26).
Since bacteria that normally reside in the oral cavity cause mouth infections, proper dental hygiene can prevent most cases of infection. As such, mouth infections are more common in populations with poor access to dental care (homeless, uninsured, etc.) or populations with health-related behaviors that damage one's teeth and oral mucosa ...
[1] [3] Tooth regeneration is an ongoing stem cell–based field of study that aims to find methods to reverse the effects of decay; current methods are based on easing symptoms. The cause of cavities is acid from bacteria dissolving the hard tissues of the teeth (enamel, dentin and cementum). [4]
Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
While a single excess tooth is relatively common, multiple hyperdontia is rare in people with no other associated diseases or syndromes. [4] Many supernumerary teeth never erupt, but they may delay eruption of nearby teeth or cause other dental or orthodontic problems. [5] [6] Molar-type extra teeth are the most common type. Dental X-rays are ...
A single tooth is smaller than normal. [3] Localized microdontia is far more common than generalized microdontia, [2] and is often associated with hypodontia (reduced number of teeth). [1] The most commonly involved tooth in localized microdontia is the maxillary lateral incisor, which may also be shaped like an inverted cone (a "peg lateral"). [3]
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
