Ⅱ型糖尿病患者种植牙二期手术后牙龈愈合状况研究

Type Ⅱ diabetics' gingival wound healing following a second surgery of dental implantation

目的研究不同血糖控制水平的Ⅱ型糖尿病患者行口腔种植二期手术术后牙龈愈合状况。方法选择69名下颌后牙区种植手术的糖尿病患者按照血糖控制水平分组,并纳入22名非糖尿病患者,行埋入式种植。种植二期手术后1、2、3、4、5周测量患者牙龈指数、牙龈高度并进行统计分析。结果所有患者种植二期手术术后牙龈指数呈降低趋势(P<0.05),同组患者在第4、5周牙龈指数无差异(P>0.05),同一时间血糖水平越高牙龈指数越高(P<0.05);术后第1、2周高糖尿病患者牙龈指数显著高于对照组(P<0.05)。术后牙龈高度随时间降低,平均较第1周降低0.65mm,糖尿病组与非糖尿病组无差异(P>0.05)。结论糖尿病患者与非糖尿病患者种植二期术后牙龈的愈合情况基本一致,糖尿病患者炎症反应更为严重,并且与血糖控制水平相关。

Objective To understand type II diabetics＇ gingival wound healing after a second surgery of dental implantation. Method Firstly, 69 patients of diabetes were chosen and divided into groups of subjects of study by glycemic control levels and 22 patients of non diabetes were subjected to dental implantation. Next, the gingival index and gingival height of the subjects as observed at 1,2,3,4, 5 weeks after a second surgery of dental implantation were documented and analyzed. Findings The gingival index and height of all patients decreased （P〈0.05）. The gingival height of patients turned to stable 4 - 5 weeks after a second surgery and the amount of gingival recession was 0.65 mm. No differences were found between the groups（P〉0.05）. The gingival index was found to have a positive correlation with the patients＇ glycemic control level （P〉 0.05） Conclusion The gingival recession of patients of both diabetes and non-diabetes who have a second surgery of dental implants turn to stable four weeks surgery.
