The purpose of this study was to determine if the use of a periodontal endoscope improves periodontal outcomes of scaling/root planing when compared to scaling/root planing alone.
Thirty subjects with moderate periodontitis were recruited from the University of Minnesota School of Dentistry. Of these, 26 completed the study. A randomized split mouth design was used to evaluate periodontal outcomes at 6 to 8 weeks and 3 month intervals after sites within 2 quadrants of each subject were scaled and root planed with or without the use of the Perioscope™. Paired t-tests were used to test whether there were within-patient differences in improvement between Perioscope™ and non-Perioscope™ sites as measured by periodontal measurements (probing depth, clinical attachment level) and indices of gingival inflammation, including bleeding on probing (BOP) and gingival inflammation (GI). P-values less than 0.05 were declared to be statistically significant.
Less BOP and GI were found in the Perioscope™ sites at visit 1 and visit 2. Reduction in pocket depth and clinical attachment loss was achieved for all sites but probing depth and clinical attachment level changes were found to be unrelated to the use of the Perioscope™. Mean probing depth (SD) was reduced from 5.29 mm (0.4) to 3.55 mm (0.8) in the Perioscope™ sites and 5.39 mm (0.5) to 3.83 mm (1.2) in non-Perioscope™ sites from baseline measurements to visit 2.
The adjunctive use of the periodontal endoscope improved periodontal outcomes with respect to gingival inflammation and bleeding upon probing. The adjunctive use of the Perioscope™ was not found to be superior to traditional scaling and root planing with regard to pocket depth reduction and clinical attachment loss.
本研究的目的是确定与单独进行龈下刮治和根面平整相比,使用牙周内窥镜是否能改善龈下刮治/根面平整的牙周治疗效果。
从明尼苏达大学牙科学院招募了30名中度牙周炎患者。其中,26名完成了研究。采用随机分组口内对照设计,在每位受试者的2个象限内的部位进行龈下刮治和根面平整,使用或不使用牙周内窥镜(Perioscope™),并在6至8周以及3个月的间隔时间评估牙周治疗效果。采用配对t检验,以检测通过牙周测量指标(探诊深度、临床附着水平)和牙龈炎症指标(包括探诊出血(BOP)和牙龈炎症(GI))衡量的,牙周内窥镜(Perioscope™)治疗部位与非牙周内窥镜(Perioscope™)治疗部位在患者个体内改善情况的差异。P值小于0.05被认为具有统计学意义。
在第1次和第2次就诊时,牙周内窥镜(Perioscope™)治疗部位的探诊出血(BOP)和牙龈炎症(GI)较少。所有部位的牙周袋深度均有降低,临床附着丧失也有所改善,但发现探诊深度和临床附着水平的变化与牙周内窥镜(Perioscope™)的使用无关。从基线测量到第2次就诊时,牙周内窥镜(Perioscope™)治疗部位的平均探诊深度(标准差)从5.29毫米(0.4)降至3.55毫米(0.8),非牙周内窥镜(Perioscope™)治疗部位从5.39毫米(0.5)降至3.83毫米(1.2)。
牙周内窥镜的辅助使用在牙龈炎症和探诊出血方面改善了牙周治疗效果。在减少牙周袋深度和临床附着丧失方面,未发现牙周内窥镜(Perioscope™)的辅助使用优于传统的龈下刮治和根面平整。
