Abstract
ObjectiveThe aim of the present 2-year follow-up study was to assess the effect of oral hygiene maintenance on hemoglobin Alc (HbA1c) levels and peri-implant parameters around immediately-loaded dental implants placed in type-2 diabetic patients with varying glycemic levels.
Material and methodsNinety-one individuals were divided into three groups. In group 1, 30 systemically healthy individuals were included (HbA1c<6%). Patients in group 2 and 3, comprised of 30 patients with T2DM (HbA1c 6.1-8%); and 31 patients with T2DM (HbA1c 8.1-10%) respectively. In all groups, patients received immediately loaded bone level implants. All participants were enrolled in a 6 monthly periodontal/peri-implant maintenance program. Peri-implant bleeding on probing (BOP), probing depth (PD), and marginal bone loss (MBL) were measured at 6, 12, and 24months of follow-up.
ResultsMean preoperative HbA1c levels in patients in groups 1, 2, and 3 were 4.5%, 6.8%, and 8.7% respectively. In group-1, there was no significant difference in HbA1c levels at all follow-up durations. Among patients in groups 2 and 3, there was a significant decrease in HbA1c levels at 24-months follow-up than 6-months follow-up. At 6months follow-up, BOP, PD, and MBL were significantly higher among patients in group-3 than group-1. At 12 and 24months follow-up, there was no significant difference in BOP, PD, and MBL in all groups.
ConclusionsOral hygiene maintenance reduces hyperglycemia and peri-implant inflammatory parameters around immediately loaded dental implants placed in type 2 diabetic patients.
