Risk Factors Associated with Tooth Wear Among Nepalese Adults
Objectives: Tooth wear is the non-carious loss of tooth structure due to attrition, abrasion or erosion. The objective of the study was to determine the risk factors of tooth wear among the young adults in Bharatpur Metropolitan City of Nepal.
Methods: An age and sex matched case-control study was conducted among 332 young adults (cases-166, controls-166) in Bharatpur Metropolitan City of Nepal. Adults aged 20-30 years of both genders, willing to give consent, were included in this study while those with heavy restorations in cementoenamel junctions, undergoing orthodontic and periodontal treatment were excluded. The study participants first filled a self-administered questionnaire and then received an intraoral examination. Tooth wear was graded corresponding to the Smith and Knight classification of tooth wear. All the data were analyzed using SPSS version 16. A chi-square test was carried out to evaluate the association. Multivariate analysis was carried out with logistic regression analysis.
Results: Of the 332 participants, 40.4% were men and 59.6% were women. Among the studied factors, indigestion issues, frequency of changing toothbrush, types of toothpaste, consumption of sports drink, teeth grinding and chewing churpi showed statistically significant association with tooth wear (p<0.05). Further multivariate analysis showed a statistically significant association between indigestion, frequency of changing toothbrush, types of toothpaste used and rinsing of mouth after meal (p<0.05).
Conclusions: Among the factors analyzed, tooth wear was associated with frequency of changing toothbrush, types of toothpaste used and rinsing of mouth after a meal.
