摘　　要：目的比较内窥镜下龈下刮治与传统龈下刮治清除龈下牙石的效果。方法收集16例患者26颗无保留价值的重度慢性牙周炎患牙,随机分为两组,每组8例13颗患牙,分别行牙周内窥镜下龈下刮治(A组)及传统龈下刮治(B组),每颗患牙均刮治10min后拔除,亚甲基蓝染色后,蓝色显示残留牙石,对每颗牙颊、舌、近中及远中面拍照并用Image Pro Plus图像分析软件检测、计算各牙面的牙石残留率。比较两组患牙治疗后的牙石残留率以及吸烟、牙周探诊出血位点数和牙周探诊深度对牙石清除效果的影响。结果 A组患牙平均牙石残留率为(8.34±1.70)%,B组患牙平均牙石残留率为(13.02±3.36)%,差异有统计学意义(P<0.05)。吸烟、探诊出血位点数、牙周探诊深度对治疗后的牙石残留率均有影响(P<0.05)。结论在牙周内窥镜下行龈下刮治,清除牙石的效果明显优于传统龈下刮治。吸烟、探诊出血、探诊深度对牙石残留率均有影响。Objective Compare the effect of plaque and calculus removal by scaling and root planing （SRP） with or without perioscopy in chronic periodontitis. Methods Sixteen subjects with 26 loosening teeth were randomly divided into SRP＋perioscopy group （groupA, n=13） and SRP group （group B, n=13）. Each tooth was extracted after 10 mins’ SRP. Methylene-blue were used to show the residual calculus on four tooth surfaces （buccal, lingual, mesial, distal）. A digital camera and image analysis software were used to determine the percentage of residual calculus. Results The percentage of residual calculus in group A and B were （8.34±1.70）% and （13.02±3.36）% （P〈0.05） respectively. Smoking, bleeding on probing （BOP）, and probing depth （PD） between two groups were related with the residual calculus percentage. Conclusion The use of perioscopy can resulted in a statistically significant overall improvement in calculus removal in SRP.
