The aim of the study was to examine the frequencies of the genotypes and alleles of <i>ACE</i> insertion/deletion (I/D) polymorphism and their association with dental caries in a sample of Polish children. The study subjects were 120 children with dental caries experience (cases) and 41 caries-free individuals (controls). The genotyping was performed using polymerase chain reaction. The genotype distributions of <i>ACE </i>I/D polymorphism were not statistically different between carious and control children. However, we found a borderline overrepresentation of the II + ID genotypes versus the DD genotype in the carious compared to the control group (69.2% and 51.2%, respectively, p = 0.057). Logistic regression analysis adjusted for age and sex revealed that I allele carriage was a significant predictor of dental caries susceptibility (OR = 2.14, 95% CI = 1.02-4.49, p = 0.041). In conclusion, the DD genotype of <i>ACE</i> I/D polymorphism might be protective against dental caries in Polish children.
