Abstract: Introduction: Periodontitis control helps to prevent and control diabetes mellitus and understanding of this relationship can lead to changes in health policy.

Objective: The purpose of this study was to investigate the association between periodontitis, knowledge, and glycemic control.

Material and method: This is a cross-sectional analytical epidemiological survey with 216 Type 2 diabetic patients, non-smokers, who had current blood screenings with glycated hemoglobin (HbA1c).

Result: Overall, 93.51% of the patients reported brushing their teeth at least twice a day, 62.5% visited the dentist last year, 81.58% have already undergone treatment for periodontal disease, 43.52% reported having periodontitis and 59.72% had controlled diabetes. No significant (p=0.603) association between HbA1c control and the presence of periodontitis was found. Among the patients with periodontitis, no association between HbA1c control and information on the periodontal disease was found (p=0.996), and know/believe in its relationship with diabetes (p=0.659; p=0.973).

Conclusion: No relationship between periodontitis and diabetes was found in the sample, as well as in patients with periodontitis, those with knowledge on periodontal disease and knowledge/belief in its relationship with diabetes, which could be justified by the care by a multi-professional health team.

Resumo: Introdução: O controle da doença periodontal auxilia na prevenção e no controle do diabetes mellitus. A compreensão dessa relação pode desencadear mudanças nas políticas públicas de saúde.

Objetivo: O objetivo deste estudo foi investigar a associação entre a doença periodontal, o controle glicêmico e o conhecimento dessa relação.

Material e método: Trata-se de um inquérito epidemiológico analítico transversal com 216 pacientes com diabetes mellitus tipo 2, não fumantes, que realizaram exames de sangue atuais com hemoglobina glicada (HbA1c).

Resultado: No geral, 93,51% dos pacientes relataram escovar os dentes pelo menos duas vezes ao dia, 62,5% visitaram o dentista no último ano, 81,58% já fizeram tratamento para doença periodontal, 43,52% relataram ter periodontite e 59,72% tinham diabetes controlado. Não foi encontrada associação significativa (p=0,603) entre o controle da HbA1c e a presença de periodontite. Entre os pacientes com periodontite, não foi encontrada associação entre o controle da HbA1c e informações sobre a doença periodontal (p=0,996), e conhecer/acreditar na sua relação com o diabetes (p=0,659; p=0,973).

Conclusão: Não foi encontrada relação entre a doença periodontal e diabetes na amostra, o que poderia ser justificado pelo atendimento por uma equipe multiprofissional de saúde no Sistema Único de Saúde Brasileiro.
