Efficacy of the combination of minocycline and periodontal basic therapy in type 2 diabetes mellitus patients with chronic periodontitis

Abstract

Purpose: To investigate the clinical efficacy of the combination of minocycline and periodontal basic treatment on type 2 diabetes mellitus (T2DM) patients with chronic periodontitis (CP) and its impact on inflammatory factors.
 Methods: A total of 90 T2DM patients with CP admitted to the Department of Stomatology in Hainan Medical College Second Affiliated Hospital, China from January 2020 to October 2022, were enrolled in this study and randomly assigned to two equal groups, viz, study and control group. Study group received minocycline in addition to routine hypoglycemic control and basic periodontal treatment, while control group received only routine hypoglycemic control and basic periodontal treatment. Treatment lasted for 8 weeks. Efficacy of the combination of minocycline and periodontal basic treatment of T2DM patients with CP in the two groups, as well as the periodontal probing depth (PD), clinical attachment loss (CAL), bleeding on probing (sulcus bleeding index, SBI), interleukin-36 (IL-36), interleukin-1β (IL1β), tumor necrosis factor-α (TNF-α), glycated hemoglobin (HbA1c) level, chewing function score, Oral Health Impact Profile-14 (OHIP-14) score, and incidence of adverse reactions before and after treatment were determined.
 Results: The effectiveness/efficacy of treatment in study group (91.11 %) was significantly higher than in control group (75.56 %, p < 0.05). After treatment, study group had reduced PD, PLI, and SBI scores than control group (p < 0.05). Study group also showed lower levels of IL-1β, IL-36, and TNF-α as well as reduced OHIP-14 score and a higher chewing function score than control group (p < 0.05).
 Conclusion: The combination of minocycline with periodontal basic treatment improves the efficacy in T2DM patients with CP, and reduces the level of inflammatory factors with a good margin of safety.
