Abstract
The objective of this systematic review was to identify genetic variants of the IL-23, IL-17, IL-23R and IL-17R genes and isoforms and its possible association with increased development of periodontitis and peri-implantitis. A systematic review was prepared according to the guidelines, registered in the OSF database with the registration number: 10.17605/OSF. IO/X95ZC. The electronic search was performed in four databases: PubMed, Scopus, Web of Science, and Google Scholar from 1984 until March 15th, 2024. The JBI Critical Appraisal Checklist for Case-Control Studies was used to assess the quality of included studies. Eighteen papers with a case-control design were those that ultimately met the eligibility criteria. A total of 3904 individuals (2315 with periodontitis and 90 with peri-implantitis), and 1589 healthy subjects) were studied. The age range of the study population was 14-70 years, with a mean age ± (SD) of 40.43 ± 6.33 years. A total of 28 genetic variants corresponding to the IL-17A (rs 2275913, rs 3819024, rs 10484879) IL-17F (rs 763780), IL-17R (rs 879576) and IL-23R (rs 11209026) genes were analyzed in this study. Six (33.3%) studies found an association between the IL-17A 197 G/A (rs 2275913) genetic variant and peri-implantitis and periodontitis. One study (5.5%) found an association between the IL-17A rs10484879 variant and peri-implantitis and periodontitis. Six polymorphisms were evaluated, highlighting rs 2275913 of the cytokine IL-17A in patients with periodontitis or peri-implantitis. Only 50% of studies found an association despite having a small sample. This suggests that other factors such as the degree of disease, systemic diseases and ethnic groups studied may play a role.
