Caries status in asthmatic children receiving anti-asthma inhalers

Background and Aim: Background & Aim: Asthma is known as a probable risk factor for dental caries; however there is some controversy in this issue. Present study is designated to evaluate the caries status in asthmatics compared to non asthmatic controls. In addition probable factors and co-varieties associated with dental health were also investigated. Materials & Methods: Forty five asthmatics and 46 healthy controls aged 6 to 12, entered this case-control study. There was a history of asthmatic drugs for at least one year including inhalators of beta-agonist, Corticosteroid or both. DMFS Index recorded according to visual- tactile method. Stimulated saliva was obtained and microbial count performed as CFU/ml for S. Mutans and Lacto Bacilli. Data analysis performed according to t-test, Mann-Whitney, Kendallʹs Rank Correlation and Ridge Regression. Results: Mean DMFS Index was 3.98±2.53 in asthmatics and 4.3±2.81 in healthy controls. The difference was not significant caries. Final Ridge Regression showed significant correlation between drug regimen and caries (P=0.001, r=0.76). Those received beta agonist along with protective corticosteroid had significantly less caries compare to beta agonist alone (P<0.001). S. Mutans count revealed significantly higher in controls. Lactobacilli count was not significantly different. Conclusion: DMFS index was not significantly different. Inhaled corticosteroids in asthmatics leads to better control of disease process, and reduce dental caries maybe because of reduced beta 2-agonist consumption as a potent xerostomic
