Popis: | Subjects susceptible to chronic periodontitis (CP) show a high risk for the development of peiimplantitis (PI). Both diseases are multifactorial, presenting similarities in their pathophysiology and polygenic profile. MMP-13 (matrix metalloproteinases 13/ collagenase 3) is a collagenolytic enzyme, which expression is induced by TGF beta 3 (transforming growth factor type 3) in human gingival fibroblasts and inhibited by TIMP-2 (tissue inhibitor of metalloproteinase type 2). The aim of this study was to investigate the occurrence of peiimplantitis (PI) in subjects with history of chronic periodontitis (CP) and polymorphisms frequency in MMP13, TIMP2 and TGFB3 genes. One hundred and sixty-three volunteers received dental implant placement were submitted to oral and radiographic examination in order to identify past history of CP or presence of PI. Volunteers were divided into 4 groups: Control (without PI and CP, n=72), CP (with CP and without PI, n=28), PI (with PI and without CP, n=28) and diseased (with CP and PI, n=35). The chi-square test correlated genotypes in specific regions of MMP13 (rs2252070), TIMP2 (rs7501477) and TGFB3 (rs2268626) genes, considering the interaction between CP and PI. The results showed that volunteers with CP had 3.2 times more susceptibility to develop PI (p=0.0004) compared to those without CP. No significant association was observed in MMP13, TIMP2 and TGFB3 genes with CP or PI. CP is a risk factor to develop PI, however, there is no association of both diseases with polymorphisms in the MMP13, TIMP2 and TGFB3 genes. Resumo Indivíduos susceptíveis à periodontite crônica (CP) apresentam alto risco para o desenvolvimento de periimplantite (PI). Ambas doenças são multifatoriais e apresentam similaridades na patofisiologia e perfil poligênico. A MMP-13 (metaloproteinase da matriz tipo 13) é uma enzima colagenolítica cuja expressão é induzida por TGF beta 3 (fator transformador do crescimento tipo 3) nos fibroblastos gengivais humanos e inibida por TIMP-2 (inibidor tecidual de metaloproteinase tipo 2). O objetivo deste estudo foi investigar a ocorrência de periimplantite em sujeitos com periodontite crônica e a frequência dos polimorfismos nos genes MMP13, TIMP2 e TGFB3. Cento e sessenta e três voluntários submetidos à instalação de implantes endósseos foram analisados clínica e radiograficamente quanto à presença de histórico de CP e PI, sendo divididos em 4 grupos: Controle (sem história de CP e PI, n=72), CP (com CP e sem PI, n=28), PI (com PI e sem CP, n=28) e Doentes (com CP e PI, n=35). O teste do qui-quadrado correlacionou os genótipos nas regiões dos genes MMP13 (rs2252070), TIMP2 (rs7501477) e TGFB3 (rs2268626), considerando a interação entre CP e PI. Os resultados mostraram que voluntários com CP possuem 3.2 vezes mais chances de desenvolver PI (p=0.0004) comparados aos sem CP. Nenhuma associação significativa foi observada entre os genes MMP13, TIMP2 e TGFB3 e CP ou PI. A CP é um fator de risco ao desenvolvimento de PI, no entanto, não há associação entre ambas as doenças com polimorfismos nos genes MMP13, TIMP2 e TGFB3. |
