Frequency distributions for bivariate analysis and logistic regression for multivariate analysis were used for statistical analysis. Prevalence of oral impacts was high (60%), with a mean score of 2.49 +/- 3.92. A significant association (P </= .05) was observed in oral impacts on daily performances with age, presence of dental caries, traumatic injuries, and dentofacial anomalies score. A strong association between clinical dental indicators and oral impacts in children showed eating followed by cleaning of teeth and smiling as the most commonly affected daily performances.
