可摘局部义齿对Ⅱ型糖尿病患者基牙牙周状况的影响

The impacts of the removable partial dentures on the periodontal statuses of the type Ⅱ diabetic patients′ abutments

目的研究可摘局部义齿对Ⅱ型糖尿病患者基牙的影响程度。方法选取口腔门诊就诊的Ⅱ型糖尿病患者60例,牙周非手术治疗后进行可摘局部义齿修复,研究基牙与其对侧同名牙于义齿修复前、修复后2周、3个月、6个月、12个月、24个月的菌斑指数、牙龈指数、探诊出血指数、探诊深度和临床附着丧失5项牙周指标。结果 1)Ⅱ型糖尿病患者戴用可摘局部义齿后基牙的牙周指标明显高于对照牙(P<0.01);2)Ⅱ型糖尿病患者戴用可摘局部义齿后的6个月内,基牙的牙周指标均明显升高(P<0.01);但随着戴用时间继续延长,基牙的牙周状况趋于稳定和缓解。结论戴用可摘局部义齿可引起Ⅱ型糖尿病患者基牙牙周指数的升高。

Objective To study the impacts of the removable partial dentures on the periodontal statuses of the type Ⅱ diabetic pa- tients＇ abutments. Methods Sixty type Ⅱ diabetic patients were selected randomly in the dental clinic. After the non-surgical perio- dontal treatment, removable partial dentures were restored. Five indices, including plaque index （PLI） , gingival index （GI） , bleed- ing index （BI） , probing depth （PD） and attachment loss （AL） were compared between the abutments and the counterpart teeth on the opposite side at different time points, including before the restoration and 2 weeks, 3 months, 6 months, 12 months ,24 months after the restoration. Results 1 ） The periodontal indices of the abutments of the type ]I diabetic patients were significantly higher than those of their counterparts（ P 〈 O. O1 ） ; 2） Indices of PLI, GI, BI, PD and AL of the abutments of the type Ⅱ diabetic patients elevated within 6 months after the restoration （P 〈 0.01 ）. However, the periodontal condition tended to be stabilized and relieved as the usage time of the dentures extended further. Conclusions The removable partial denture restoration leads to the increase of the periodontal indices of the abutments of the type Ⅱ diabetic patients.
