An individual tooth wear index and an analysis of factors correlated to incisal and occlusal wear in an adult Swedish population

Abstract

The aim of the study was to introduce an individual tooth wear index and to use this index to investigate factors correlated to occlusal wear. The material consisted of 585 randomly selected dentate individuals from the community of Jönköping, Sweden, who in 1983 reached the age of 20, 30, 40, 50, 60, 70, or 80 years. The degree of incisal and occlusal wear was evaluated for each single tooth in accordance with criteria presented earlier. An individual tooth wear index, which made it possible to rank individuals in accordance with incisal and occlusal wear, was used as dependent variable to investigate factors related to incisal and occlusal wear. Of all factors analyzed, the following were found to correlate significantly with increased incisal and occlusal wear: number of existing teeth, age, sex, occurrence of bruxism, use of snuff, and saliva buffer capacity. Stepwise multiple regression analysis gave a total explanation factor of R2 = 0.41. It was also possible to distinguish well between groups of individuals with and without tooth wear by means of these factors.

Tooth wear among patients suffering from mental disorders

“…Insensitive to pain associated with illness and injury, has been reported frequently in this population (67)(68)(69)(70)(71)(72)(73). It is important to underline that even if severe tooth wear has an impact on oral pain levels (74), in the population studied none of the patients examined referred oral or tooth pain. Pain insensitivity could lead to a delay in diagnosis and treatment.…”

Dentin hypersensitivity: pain mechanisms and aetiology of exposed cervical dentin

“…Foodstuffs are known to wear the occlusal surface of the teeth [114]; for example, the erosive nature of roasted vegetables compared to other cooking styles [130]. Attrition [131] may play a role in some cases of occlusal dentin hypersensitivity, due to parafunctional habits like bruxism [132]. …”

Tooth surface loss: an overview

“…5,[40][41][42] However, the exact prevalence is unclear, primarily because of differing assessment criteria. 42 Hugoson et al, 39 for example, reported that 13-24% of surfaces showed evidence of occlusal wear.…”
