A fiber-optic periodontal endoscope was developed to aid in the visualization of subgingival structures and to improve the diagnosis and management of periodontal diseases. The purpose of this study was to determine whether use of the periodontal endoscope with scaling and root planing (SRP) resulted in a decrease in residual calculus compared to SRP alone.
Fifteen subjects with 50 tooth pairs participated in this study. Each tooth per pair was randomized to receive SRP with or without the endoscope. Teeth were extracted, and a stereomicroscope and digital image analysis was used to determine percent residual calculus present in a masked fashion.
There was 2.14% (P < 0.001) more residual calculus at control versus test sites. At buccal/lingual and interproximal surfaces, mean differences in residual calculus were 1.30% (P <0.015) and 2.93% (P < 0.001), respectively. Test treatment time decreased significantly as operator experience increased. There were no statistically significant differences between residual calculus for test and control teeth at shallower probing depths; however, at deeper probing depths, the use of the endoscope resulted in significantly less residual calculus.
The use of the periodontal endoscope resulted in a statistically significant overall improvement in calculus removal during SRP, which was most evident in deeper probing depths. The clinical significance of this level of improvement is unknown.
开发了一种光纤牙周内窥镜，以辅助观察龈下结构，并改善牙周疾病的诊断和治疗。本研究的目的是确定与单纯龈上洁治和根面平整术（SRP）相比，使用牙周内窥镜进行SRP是否能减少残余牙石。
15名受试者的50对牙齿参与了本研究。每对牙齿中的每颗牙齿随机接受有或无内窥镜的SRP。拔牙后，使用体视显微镜和数字图像分析以盲法确定存在的残余牙石百分比。
对照部位的残余牙石比试验部位多2.14%（P < 0.001）。在颊侧/舌侧和邻面，残余牙石的平均差异分别为1.30%（P < 0.015）和2.93%（P < 0.001）。随着操作者经验的增加，试验治疗时间显著减少。在较浅的探诊深度，试验牙和对照牙的残余牙石之间无统计学显著差异；然而，在较深的探诊深度，使用内窥镜导致残余牙石显著减少。
使用牙周内窥镜在SRP期间牙石清除方面有统计学显著的总体改善，这在较深的探诊深度最为明显。这种改善水平的临床意义尚不清楚。
