Background: Dental health is one of the most important health burdens of children health. The association between dental health and endocarditis has been already demonstrated, but there is controversy about different frequency of dental caries, periodontitis, and saliva microorganism in
comparison to healthy population and children with congenital heart diseases (CHDs). In this study, we evaluated these differences.

Methods: Seventy‑six healthy children and 68 CHD patients were enrolled in the present case–control study. Dental decay, periodontitis, oral microorganisms, serum calcium, phosphorus, and frequency of carbohydrate and protein consumption of all participants were evaluated by standards method.

Results: CHD patients experienced more periodontitis, but the difference was not signifcant (0.12 vs. 0.09, P = 0.2). In healthy children, the mean saliva colony counts of Streptococcus mutans were more signifcant (50639 ± 3324 vs. 35285 ± 27226, P = 0.03), which was diminished by adjusting the carbohydrate consumption. The mean colony count of Lactobacilli in children with CHD was nonsignifcant higher than healthy children (P = 0.3).

Conclusions: Pediatric patients with CHD experience insignifcantly higher dental decay, periodontitis, and saliva Lactobacilli colony counts. The frequency of decayed tooth and gingival diseases in healthy children is high, and hence, more dental care attention in our health system is
needed for healthy children.
