Periodontal status in patients suffering from diabetes mellitus in relations to glycosylated hemoglobin level and the level of oral hygiene

Introduction. It has been known that periodontitis is one of the most common oral diseases in patients having diabetes mellitus (DM). The aim of this study was to examine the influence of glycosylated hemoglobin (HbA1c) level and the level of oral hygiene on periodontal status of patients suffering from DM. Material and Methods. The research included 50 people with type 2 DM randomly selected. Based on values of HbA1c, patients were divided into two groups: well controlled DM (HbA1c?8.5%) and poorly controlled DM (HbA1c>8.5%). Patients with poorly and well controlled DM were further grouped into subgroups depending on the level of oral hygiene. For each patient, during the clinical examination, periodontal parameters were determined: plaque index (PI), sulcus bleeding index (SBI), the level of junctional epithelium (LJE) and periodontal pocket depth (PPD). Results. The results showed that patients with well controlled disease and good oral hygiene had lower values of the examined periodontal parameters (SBI and PPD) then patients with poorly controlled DM and worse oral hygiene (p
