Abstract
Objectives:The aim of this study was to evaluate the epidemiology of tooth wear in Beijing and to establish appropriate preventive measures.Materials and Methods:This cross-sectional analysis involved a questionnaire survey conducted for 1,812 individuals aged 12–74 years in Beijing. Subjects were local residents living in the region for >6 months before the survey. Subjects were evaluated using clinical examinations with the basic erosive wear examination index and a self-administered questionnaire. Statistical analyses were performed using SPSS software.Results:The prevalence of maxillary tooth wear was 84.9% for the molars, 68.9% for the premolars, 74.1% for the canines and 97% for the incisors. In the mandible, the corresponding prevalence rates were 85.2%, 59.3%, 78.6% and 97.4%, respectively. The occlusal, incisal and cervical surfaces showed more frequent wear compared with the other surfaces. Age, acidic beverages, xerostomia and brushing habits were identified as risk factors for tooth wear (P<0.05).Conclusions:Tooth wear is common in Beijing. Specific preventive measures should be recommended for individuals reporting excessive consumption of fruits and/or acidic beverages, and those with xerostomia. In particular, incisor wear should be carefully monitored in individuals of all age groups.
Highlights
Tooth wear is a multifactorial disease defined as the loss of hard tissue in the absence of caries or trauma.[1]
The results revealed that age; fresh fruit, vegetable juice and carbonated soft drink consumption, after brushing teeth before going to bed; and xerostomia were strong risk factors for tooth wear with high odds ratios
Street, sex, socioeconomic status, type of toothpaste, brushing time, chewing habits, use of aspirin and amphetamines, and use of electric toothbrush showed no influence on tooth wear. This cross-sectional study analysed tooth wear data collected for five age groups and, to the best of our knowledge, is among the few studies that have used the basic erosive wear examination (BEWE) index for an epidemiological survey of adolescents and adults
Summary
Tooth wear is a multifactorial disease defined as the loss of hard tissue in the absence of caries or trauma.[1] It can be classified as attrition, erosion and abrasion.[2] Attrition is defined as the physiological wear of enamel, dentin or restorations caused by tooth-to-tooth contact.[3] Erosion is defined as the loss of tooth substance caused by chemical agents, intrinsic or extrinsic acids, with no bacterial involvement. Intrinsic acids originate from gastrointestinal and eating disorders, whereas extrinsic acids are introduced in the oral cavity through the ingestion of foods or beverages, including carbonated soft drinks, fresh fruits and fruit juices. Abrasion is defined as the loss of tooth substance caused by processes involving bio-mechanical friction.[3]
