Background:There is overwhelming evidence that periodontal disease and dental caries affect the majority of populations and that western culture and lifestyle may have a profound influence on oral health,especially in adults.The present study was performed to determine the effect of westernization on the oral health of college students of Udaipur City,Rajasthan.Methods:A descriptive cross-sectional study was conducted among students attending various professional and non-professional bachelor’s degree colleges of Udaipur City,Rajasthan,India,from March 2013 to May 2013.Eight hundred students were selected based on a two-stage random sampling procedure.Westernization was assessed by a self-administered structured questionnaire.Periodontal status,dental caries status and malocclusion were assessed according to World Health Organization(WHO) criteria(1997).Statistical analysis was performed using Chi-square and Multivariate logistic regression.The confidence level and level of significance were set at 95% and 5%,respectively.Results:The present study suggested that adverse habits,listening to English music and preferring English food had a significant association with dental caries and periodontal diseases.Malocclusion also showed a significant relationship with consuming English food for snacks and desserts.Multivariate analysis revealed a significantly greater odds ratio(OR) for periodontal disease and dental caries among those who preferred English food for lunch.Conclusion:Based on the results of the present study,there is an association between westernization and oral health.
