Tooth wear refers to loss of tooth substance by means other than dental caries. Tooth wear is a very common condition that occurs in approximately 97% of the population. This is a normal physiological process occurring throughout life; but with increasing lifespan of individuals and increasing retention of teeth for life, the incidence of non-carious tooth surface loss has also shown a rise. Tooth wear varies substantially between people and groups, with extreme attrition and enamel fractures common in archaeological samples, and erosion more common today.

  • L’usure des dents est la perte de substance dentaire par d'autres moyens que la carie. Il s'agit d'un processus normal qui survient chez environ 97 % de la population. Processus physiologique normal se produisant tout au long de la vie, l'augmentation de la durée de vie des humains a augmenté l'incidence de la perte de surface dentaire non carieuse. L'usure des dents varie considérablement d'un individu à l'autre, avec une usure extrême et des fractures de l'émail courantes dans les échantillons archéologiques et l'érosion dentaire plus courante aujourd'hui.

  • L’usure des dents est la perte de substance dentaire par d'autres moyens que la carie. Il s'agit d'un processus normal qui survient chez environ 97 % de la population. Processus physiologique normal se produisant tout au long de la vie, l'augmentation de la durée de vie des humains a augmenté l'incidence de la perte de surface dentaire non carieuse. L'usure des dents varie considérablement d'un individu à l'autre, avec une usure extrême et des fractures de l'émail courantes dans les échantillons archéologiques et l'érosion dentaire plus courante aujourd'hui. L'usure des dents est principalement le résultat de trois processus : l'attrition, l'abrasion et l'érosion. Ces formes d'usure dentaire peuvent à la fracturation du tissu dentaire en raison de lésions de stress causées par des forces extrinsèques sur l'émail. L'usure des dents est un affection complexe et multifactorielle. La distinction entre les différents types d'usure dentaire (attrition, abrasion et érosion) permet de mettre en œuvre des interventions appropriées. Plusieurs indices ont été développés afin d'évaluer le degré d'usure des dents, le premier est celui de Paul Broca. En 1984, Smith et Knight développent l'indice d'usure des dents (tooth wear index TWI) qui consistent à noter l'usure sur les quatre surfaces dentaires visibles (buccale, cervicale, linguale, occlusale-incisive), quelle qu'en soit la cause. Un examen de 2008, l'indice d'usure érosive de base (Basic Erosive Wear Examination BEWE) par Bartlett et al., est maintenant également utilisé. L'âge d'un animal inconnu est habituellement calculé par l'étude de l'usure des dents, par exemple chez le cheval. (fr)
  • Tooth wear refers to loss of tooth substance by means other than dental caries. Tooth wear is a very common condition that occurs in approximately 97% of the population. This is a normal physiological process occurring throughout life; but with increasing lifespan of individuals and increasing retention of teeth for life, the incidence of non-carious tooth surface loss has also shown a rise. Tooth wear varies substantially between people and groups, with extreme attrition and enamel fractures common in archaeological samples, and erosion more common today. Tooth wear is predominantly the result of a combination of three processes; attrition, abrasion and erosion. These forms of tooth wear can further lead to a condition known as abfraction, where by tooth tissue is 'fractured' due to stress lesions caused by extrinsic forces on the enamel. Tooth wear is a complex, multi-factorial problem and there is often difficulty identifying a single causative factor. However, tooth wear is often a combination of the above processes. Many clinicians, therefore, make diagnoses such as "tooth wear with a major element of attrition", or "tooth wear with a major element of erosion" to reflect this. This makes the diagnosis and management difficult. Therefore, it is important to distinguish between these various types of tooth wear, provide an insight into diagnosis, risk factors, and causative factors, in order to implement appropriate interventions. Tooth wear evaluation system (TWES) may help determine the most likely aetiology of tooth wear. Heavy tooth wear is commonly found on the occlusal (chewing) surface, but non-carious cervical lesions from tooth wear are also common in some populations. Multiple indices have been developed in order to assess and record the degree of tooth wear, the earliest was that by Paul Broca. In 1984, Smith and Knight developed the tooth wear index (TWI) where four visible surfaces (buccal, cervical, lingual, occlusal-incisal) of all teeth present are scored for wear, regardless of the cause. A more recent index Basic Erosive Wear Examination (BEWE) from 2008 by Bartlett et al., is now also in use. (en)
