The current study aimed to investigate the effect of two nonsurgical periodontal treatment modalities on clinical periodontal parameters and glycemic control.
A randomized clinical trial was conducted with a sample of 64 type 2 diabetes mellitus (T2DM) patients with chronic periodontitis. Subjects were randomly assigned into two groups. Group I received oral hygiene instructions (OHI) at baseline and each recall visit. Group II received one-stage full-mouth scaling and root planning (SRP) combining OHI. At baseline, third month, and sixth month the plaque index (PlI), gingival index (GI), probing pocket depth (PPD), clinical attachment loss (CAL), and glycated hemoglobin (HbA1c) were recorded and analyzed.
After treatment, two groups showed significant differences for all parameters at both assessed times ( <0.05). The OHI alone only demonstrated a slight reduction in GI in third month, with no significant changes for PlI and PPD indexes. However, Group I recorded the increased HbA1c and CAL values at 6-month follow-up ( <0.05). The combination of OHI and SRP exhibited a significant improvement in all periodontal values ( <0.05). Also, the HbA1C levels of Group II showed a significant reduction after treatment and were lower than those of Group I.
Oral hygiene instructions only resulted in a better gingival condition of diabetic patients in the initial time. The nonsurgical periodontal therapy by combining SRP and OHI significantly improved both periodontal health and glycemic control.
Diabetic patients should be supplied with an effective OHI modality and a professional dental debridement.
本研究旨在探讨两种非手术牙周治疗方法对临床牙周参数和血糖控制的影响。
采用随机临床试验方法，选取 64 例 2 型糖尿病（T2DM）伴慢性牙周炎患者作为研究对象。将受试者随机分为两组。第 I 组在基线和每次随访时接受口腔卫生指导（OHI）。第 II 组接受一次全口龈下刮治和根面平整（SRP）联合 OHI。在基线、第 3 个月和第 6 个月记录并分析菌斑指数（PlI）、牙龈指数（GI）、探诊袋深度（PPD）、临床附着丧失（CAL）和糖化血红蛋白（HbA1c）。
治疗后，两组在两个评估时间点的所有参数均有显著差异（<0.05）。单独 OHI 仅在第 3 个月时对 GI 有轻微降低，PlI 和 PPD 指数无明显变化。然而，第 I 组在 6 个月随访时记录到 HbA1c 和 CAL 值增加（<0.05）。OHI 联合 SRP 表现出所有牙周值的显著改善（<0.05）。此外，第 II 组的 HbA1C 水平在治疗后显著降低，且低于第 I 组。
口腔卫生指导仅在初始阶段使糖尿病患者的牙龈状况得到改善。结合 SRP 和 OHI 的非手术牙周治疗可显著改善牙周健康和血糖控制。
应向糖尿病患者提供有效的 OHI 方法和专业的牙科洁治。
