The effect of non-surgical periodontal therapy on HbA1c levels: A systematic review

Objective: The purpose of the present article is to summarize the evidence present in systematic regarding the non-surgical periodontal therapy effects on HbA1c levels. Methods: Our study considered the consultation of the bibliographic databases "Medical Systematic Analysis and Retrieval System". The research was carried out by using the keywords: "Diabetes mellitus" AND "Periodontal disease" AND "Scaling and root planing" AND "Non-surgical periodontal treatment" AND "Glycosylated hemoglobin". Our research resulted in 18 articles published between 1995 and 2018. Results: All studies have shown that periodontal indices have improved after non-surgical periodontal therapy, while the effects on metabolic control are controversial. Some authors find no influence on metabolic variables, others report an improvement. Some studies have used both topical and systemic antibiotics in combination with causal periodontal therapy, observing an improvement in metabolic compensation. Conclusion: The approach to diabetic patient with periodontitis must be multidisciplinary with close collaboration between periodontists, dental hygienists and endocrinologists.
