牙周内窥镜辅助龈下刮治对残留牙周袋疗效的随机对照临床研究

Clinical effects of scaling and root planing with an adjunctive periodontal endoscope for residual pockets:a randomized controlled clinical study

目的比较牙周内窥镜辅助龈下刮治和根面平整(SRP)与传统SRP对慢性牙周炎患者基础治疗后残留牙周袋的临床疗效。方法将牙周基础治疗后口内每个区至少有1个位点探诊深度(PD)≥5 mm的患者纳入研究,随机分为内窥镜组和SRP组,分别对残留牙周袋位点进行内窥镜辅助SRP治疗和传统SRP治疗。在治疗前(基线)、治疗后3、6个月检查PD、探诊出血(BOP)和附着丧失(AL),采用SPSS 20.0统计学软件对数据进行统计分析。结果与基线相比,治疗后3、6个月内窥镜组及SRP组PD≥5 mm位点百分比、PD、AL、BOP阳性位点百分比均降低(P<0.05)。治疗后6个月与3个月相比,内窥镜组PD≥5 mm位点百分比、PD、AL、BOP阳性位点百分比均降低(P<0.05),而SRP组差异无统计学意义(P>0.05)。与SRP组相比,内窥镜组治疗后3及6个月PD≥5 mm位点百分比、PD均降低,治疗后6个月AL、BOP阳性位点百分比降低(P<0.05)。结论牙周内窥镜辅助SRP对于基础治疗后的残留牙周袋(PD≥5 mm)的临床疗效优于传统SRP,尤其具有更好的远期预后。

Objective To evaluate the efficacy of scaling and root planing(SRP)with a periodontal endoscope in the treatment of residual pockets in patients with periodontitis after initial periodontal therapy.Methods Patients with residual pockets[probing depth(PD)≥5 mm]were included and randomly assigned to the endoscope group(SRP with a periodontal endoscope)or SRP group(SRP alone).The PD,attachment loss(AL),and bleeding on probing(BOP)of residual pockets were recorded before treatment and at 3 and 6 months after treatment.Data were analyzed with SPSS 20.0 software.Results Compared with the baseline values,the percentage of PD≥5 mm sites,PD,AL,and BOP(+)%in the endoscope group and SRP group at 3 and 6 months after treatment decreased(P<0.05).Compared with the values at 3 months after treatment,the percentage of PD≥5 mm sites,PD,AL,and BOP(+)%at 3 and 6 months after treatment decreased in the endoscope group(P<0.05),whereas no statistical difference in these values was observed in the SRP group(P>0.05).Compared with those in the SRP group,the percentage of PD≥5 mm sites and PD at 3 and 6 months after treatment and AL and BOP(+)%at 6 months after treatment in the endoscope group decreased(P<0.05).Conclusion SRP with a periodontal endoscope shows a better effect in improving the PD,AL,and BOP of residual pockets(PD≥5 mm)in patients with periodontitis after initial periodontal therapy and has advantages in improving the long-term curative effect of this therapy.
