A comparative assessment of caries risk using cariogram among smokers and smokeless tobacco users in india - a cross-sectional study

Background: A dearth of literature exists concerning utilization of the unique cariogram model for caries risk assessment in tobacco users. Objective: To assess & compare caries risk among smokers & smokeless tobacco users using Cariogram model. Methods: A descriptive cross sectional study was conducted among smokers and smokeless tobacco users of Udaipur for 3 months. Caries risk assessment was done by employing a survey proforma based on the Cariogram model. Statistical analysis included descriptive statistics, Chi-square test followed by Marascuilo procedure and Stepwise multiple linear regression with 95% confidence interval and 5% significance level. Results: Majority of the smokers (56%) portrayed high caries risk (less chance to avoid new caries) followed by smokeless Tobacco users (34%). Only 40% smokeless tobacco users had relatively high chances (>60%) of avoiding future new caries. The susceptibility sector of the cariogram model contributed primarily to caries risk in the study population. Conclusion: The study findings from the different cariogram elements converged to indicate that smokers were at maximum caries risk, followed by smokeless tobacco users and therefore Cariogram model could be a useful tool to represent caries risk among smokers and smokeless tobacco users.
