Abstract: Periodontitis is a chronic multifactorial inflammatory disease originating from microbial, environmental and genetic factors. The present study aimed to find an association of genetic polymorphisms at IL-1A −889 and IL-1B +3953 loci in Polish patients with stage III grade B periodontitis and periodontally healthy subjects. Fifty patients with stage III grade B periodontitis (tests) and thirty-five periodontally healthy controls were included in the study. To determine IL-1A and IL-1B gene polymorphisms, buccal swab-derived DNA obtained by means of the GenoType PST test was used. There were no statistically significant differences regarding the prevalence of IL-1A −889 or IL-1B +3953 alleles between groups. The frequencies of different IL-1A −889 genotypes did not differ significantly between groups. The IL-1B +3953 C/T genotype was significantly more predominant in periodontitis patients than in controls, whereas C/C genotype prevalence was significantly lower in the test group. Complex genotypes consisting of at least one IL-1A −889 and IL-1B +3953 T allele occurred significantly more frequently in subjects with periodontitis. Stage III grade B periodontitis may be associated with the IL-1B +3953 T allele and composite IL-1 polymorphism. Reduced susceptibility to periodontal disease was present in IL-1A −889 and IL-1B +3953 C/C homozygotic patients.
