Prevalence, Distribution and Background Variables of Smooth-Bordered Tooth Wear in Teenagers in The Hague, The Netherlands

Abstract

The purposes of the study were: (1) to assess the prevalence and distribution of smooth-bordered tooth wear in teenagers, and (2) to investigate the relationship between smooth-bordered tooth wear and social background, dietary pattern, drinking habits, oral hygiene practices and caries prevalence. In The Hague, The Netherlands, a sample of 345 10- to 13-year-olds and 400 15- and 16-year-olds was clinically examined. The criteria for the assessment of smooth-bordered tooth wear (‘smooth wear’) were in line with the diagnostic criteria for erosion developed by Lussi (1996). In the age group 10–13 years, the percentage of subjects with visible smooth wear (SW1 threshold) was 3% and in 1 subject (0.3%), deep smooth enamel wear was found. Due to the low prevalence, the results for this age group were not analysed further. In the age group 15–16 years, the proportion of subjects with visible smooth wear (SW1 threshold) was 30% and that with at least deep smooth enamel wear (SW2 threshold) 11%. Smooth wear into dentine was found in 1 subject. First molars and upper anterior teeth were affected predominantly. A significant effect on visible smooth wear (SW1 threshold) was found for gender and social background. At mouth level, no significant influence was found for dietary patterns, drinking habits or oral hygiene practices. The caries prevalence was similar in subjects with and without smooth wear.

Investigation of Tooth Wear and its Associated Etiologies in Adult Patients Visiting Dental Institute in India

“…Most studies have reported the incidence to be more common in males [13]. In the present study also, out of 570 patients examined 131 (45%) patients were male and 114 (41%) were female.…”

Dietary Habits and Oral Hygiene Practice amongst Dental Students at the College of Dentistry, Princess Nourah University

“…Although not widely documented regarding dental erosive wear, sour sweets have been suggested to be a contributor too important to disregard [35] [36]. Some researchers have not found a relationship between dental erosion and fruit and acidic drinks [37] [38]. There was growing evidence in the UK, that a major cause of tooth erosion is gastroesophageal reflux, [39].…”

The Wear and Tear of Teeth

“…Since enamel is >90% hydroxyapatite by volume, it is vulnerable to chemical attack from acids, dissolving readily when the oral pH falls below 5.5. The erosion of enamel has become a serious problem in modern human populations [1,2,3,4,5,6,7], being attributed mainly to the consumption of acidic carbonated soda drinks [8]. However, gastric regurgitation [9] is also of increasing importance as a cause, particularly as the incidence of gastro-oesophageal reflux in the population increases with an increasing trend towards obesity [10].…”
