AVALIAÇÃO DA RESPOSTA CLÍNICA AO TRATAMENTO PERIODONTAL NÃO CIRÚRGICO EM PESSOAS COM HISTÓRICO FAMILIAR DE PERIODONTITE

Abstract

Aim: This interventional clinical trial evaluated the response to non-surgical periodontal treatment (NSPT) and modulating factors in patients with periodontitis and a family history of the disease. Materials and Methods A total of 52 patients diagnosed with mild or moderate periodontitis were included. Sociodemographic data, family history of the disease, systemic and oral health were accessed. Probing Depth (PD), Bleeding on Probing (BOP) and Clinical Attachment Level (CAL) were assessed before and 6 months after NSPT. Logistic regression analysis was performed to determine associations between modulating factors and family history of periodontitis (p≤0.05). Results: Presence of family history was associated with a higher percentage of sites with final PD≥5mm (OR=12.0; CI=1.99 – 72.31, P<0.001). Final PD≥5mm was also associated with male gender (OR= 10.7; 95% CI= 1.96 – 58.16; P=0.01) and lower income (OR = 5.8; CI=1.33 – 24.1; P=0.02). Bleeding on probing and clinical attachment level gain were not associated with a family history of periodontitis (p ≤ 0.07). Conclusion: A family history of periodontitis was associated with a higher rate of sites with probing depth greater than 5mm after 6 months of treatment, but was not related to worse bleeding on probing rates or clinical attachment level. It is suggested that the presence of periodontitis in the family can negatively influence periodontal repair after non-surgical periodontal therapy, and should be investigated in larger population samples.
