To evaluate the epidemiological characteristics of erosive tooth wear in primary school students aged 6-12 in Jinzhou, including: prevalence, severity, extent, intraoral distribution and associated risk factors.The data collection consists of two parts: the first part is the clinical examination of the participants. All erupted teeth were clinically assessed by three calibrated examiners, and classified according to the basic erosive wear examination (BEWE); The second part is a questionnaire about demographic information, parafunctional movement and lifestyle, completed by the parents or their guardians.A total of 1,469 children were included in this experiment; erosive tooth wear (ETW) prevalence (BEWE ≥ 1) was 54.9%. According to cumulative BEWE index, the proportion of different ETW severity (high, medium, low, none) was 6.8%, 16.3%, 27.0% and 49.9%, respectively. In an analysis of risk factors, family factor, age, gender, extracurricular study time, oral hygiene habit, bruxism, unilateral mastication and acid diet was associated with the prevalence of ETW.This study shows that ETW has a high prevalence in students aged 6-12, and more common in deciduous molars and deciduous canine. Abrasion, attrition and erosion play an important role in ETW. |
