Differences in functional variables, fillings, and tooth wear in two groups of 19-year-old individuals

Abstract

Fifty-one individuals (28 girls and 23 boys) who had received orthodontic treatment were compared with 47 subjects (19 girls and 28 boys) without such treatment as to maximal mandibular mobility, chewing muscle tenderness, morphologic occlusion, occlusal/incisal state, and degree of tooth wear. All were 19 years old. There were no statistically significant differences between the groups except for the number of teeth present and maximal mouth opening, which were both smallest in those who had received treatment. The first finding is evident, extraction of premolars being an accepted mode of orthodontic treatment. The reduced mouth opening capacity was related to an increased number of individuals with four or more palpably tender muscle sites in that group of individuals.

Attrition, occlusion, (dys)function, and intervention: a systematic review

“…Two studies were retrospective analyses reporting on relationships between tooth wear and treatment history. Orthodontic treatment history was not associated with attrition (Dahl et al 1989), whereas extensive restorative treatment and treatments including extraction of teeth seemed to increase the risk for tooth wear (Dettmar & Shaw 1987). No studies were found addressing interventions at certain threshold values of attrition.…”

“…This study (Hachman et al 1999) reported on the effect of a non‐restorative therapy (bite‐plate) to reduce attrition. The two included retrospective studies (Dettmar & Shaw 1987; Dahl et al 1989) cannot be considered intervention studies. They did not compare the true effects of one treatment to another, but merely looked at TSL as a side effect of variable treatments in the past.…”

Paradigmatic shifts in occlusion and temporomandibular disorders

“…Studies of attrition generally relate to changes in the occlusion with age, function, restorations present, bruxism, and 'TMD' (Beyron, 1954;Molnar et al, 1983;Hugoson et al, 1985Hugoson et al, , 1988Dahl et al, 1989;Seligman & Pullinger, 1995). The results of these studies suggest that individuals in general may maintain a low level of wear over their lifetime while others show very high levels very early in life.…”

Tooth Wear, Etiology, Diagnosis and Its Management in Elderly: A Literature Review

“…17 Epidemiological studies of young adults reported that prevalence of tooth wear was in the range 6 to 45%. 18,19 Increased levels of wear in the old age groups are reportedly consistent 20,21 Prevalence of tooth wear of young adults in a United Kingdom study it was reported that a mean proportions of teeth with some moderate wear increased from a few percent to 9% individuals over 65 years of age.…”
