Abstract

Background: Interleukin-10 (IL-10) is a non-inflammatory cytokine, and has a positive association with periodontitis. IL-10 (rs1800871) polymorphisms in the IL-10 site have been linked with variable expression. Aim: Goal of this search was to study a link amidst the polymorphisms of these genes and deep-seated of gum disease in Iraqi patients. Methods: 120 blood specimen were collected, 60 of which were from patients with chronic periodontitis and 60 from healthy controls for comparison. Polymerase chain reaction-restriction fragment length polymorphism (PCR) for purpose of analyze IL-10 (rs1800871). Chi-square test was used to statistically analyze the data. Problems related to individual alleles, genotypes, and phenotypes were identified by various logistic regression test to determine odds ratio (OR) and 95% confidence interval (CI). P < 0.05 is significant.  Results: Prevalence of TC, CC genotypes of IL10‑819 were importantly various amidst CP and healthy in simile with TT genotype (OR = 9.72; CI = 3.36–24.4; P = 0.001 for C vs. TT, OR = 5.41; CI = 1.8–8.14; P < 0.001 for TC vs. TT). In addendum, themes with at minimum one IL10‑819‑C allele were importantly had high danger for CP (OR = 6.2; CI = 3.52–10.8; P < 0.001).  Conclusion: Our results concluded the IL-10 gene polymorphism (-819T/C) is potential to be a danger agent for chronic periodontitis in Iraqi patients.
