The aetiology of dental abrasion can be due to a single stimulus or, as in most cases, multi-factorial. [6] The most common cause of dental abrasion is the combination of mechanical and chemical wear. Tooth brushing is the most common cause of dental abrasion, which is found to develop along the gingival margin, due to vigorous brushing in this ...
Abfraction is a form of non-carious tooth tissue loss that occurs along the gingival margin. [2] In other words, abfraction is a mechanical loss of tooth structure that is not caused by tooth decay, located along the gum line. There is theoretical evidence to support the concept of abfraction, but little experimental evidence exists. [3]
The teeth of the Forfexopterus lower jaw specimen SDUST V1007 showed signs of abrasion near the tip of the crown, with the teeth having wear facets on the outer , inner , or both surfaces. The facets on the outer surfaces tended to be relatively low-angled, and were only present on more heavily-worn teeth.
Tooth wear refers to loss of tooth substance by means other than dental caries. [1] Tooth wear is a very common condition that occurs in approximately 97% of the population. [ 2 ] This is a normal physiological process occurring throughout life; but with increasing lifespan of individuals and increasing retention of teeth for life, the ...
Tooth wear is another key feature of dental remains that can be analysed to infer past diets. Wear that is the result of natural contact between upper and lower teeth is called attrition, and wear that is the result of external objects like food coming into contact with the teeth is called abrasion. [29]
Severe wear of the lower teeth in a bulimic person. Intrinsic dental erosion, also known as perimolysis, is the process whereby gastric acid from the stomach comes into contact with the teeth. [14] This is often secondary to conditions such as anorexia nervosa, bulimia nervosa, gastroesophageal reflux disease (GERD) and rumination syndrome.
In 1891, Victor Haderup devised a variant of eight tooth quadrant system in which plus (+) and minus (-) were used to differentiate between upper and lower quadrants, and between right and left quadrants (e.g., +1 = upper right central incisor; 1- = lower left central incisor). Primary teeth were numbered as upper right (05+ to 01+), lower left ...
Attrition, abrasion, erosion or a combination of these factors are the main reasons for tooth wear in elderly people who retain their natural teeth. This tooth wear can be pathological or physiological. [10] The number of teeth with incisal or occlusal wear increases with age. [11] [12] Attrition occurs in 1 in 3 adolescents. [12]
