title: Some socio-demographic attributes as covariates in tooth wear among males in a rural community in Nigeria.
abstract: BACKGROUND
  Association between some socio-demographic attributes and tooth wear among adult male population in a rural community of Igbo-ora, Southwestern Nigeria was investigated in this cross-sectional study.
  
  
  METHODS
  Cross-sectional study among 200 consenting adult males in Igbo-ora was carried out using a 10-item semi-structured questionnaire to obtain data on socio-demographics. Oral examination to establish the presence of tooth wear lesions was carried out by two examiners. Frequencies and percentages of relevant variables were generated. Multivariate analysis was used to test associations between categorical variables at P<0.05.
  
  
  RESULTS
  The mean age of participants was 35.6±11.7 years. One hundred and six (53.0%) subjects had one form of tooth wear lesion. Sixty eight (34.0%) of the subjects had attrition only and 96 (48.0%) had multiple tooth wear lesions. There was an association between age group, marital status, level of education and tooth wear (p<0.05). However, the association between occupation and tooth wear was not statistically significant (p>0.05). After adjusting for marital status, occupation and level of education, the association between age group and tooth wear was still significant. Though marital status was found to be associated with tooth wear, this association was not significant after adjusting for age, occupation and level of education. The association between some of the socio-demographic factors studied and the types of tooth wear was statistically significant (p<0.05).
  
  
  CONCLUSIONS
  Age group was the only independent predictor of tooth wear.
