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.
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.
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).
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.
评估使用牙周内窥镜进行龈下刮治和根面平整（SRP）治疗牙周炎患者经过初始牙周治疗后残留牙周袋的疗效。
纳入有残留牙周袋[探诊深度（PD）≥5mm]的患者，并随机分为内窥镜组（使用牙周内窥镜进行SRP）或SRP组（单纯SRP）。记录治疗前以及治疗后3个月和6个月时残留牙周袋的PD、附着丧失（AL）和探诊出血（BOP）情况。使用SPSS 20.0软件进行数据分析。
与基线值相比，内窥镜组和SRP组在治疗后3个月和6个月时，PD≥5mm部位的百分比、PD、AL和BOP（+）%均下降（P<0.05）。与治疗后3个月时的值相比，内窥镜组在治疗后6个月时PD≥5mm部位的百分比、PD、AL和BOP（+）%下降（P<0.05），而SRP组这些值无统计学差异（P>0.05）。与SRP组相比，内窥镜组在治疗后3个月和6个月时PD≥5mm部位的百分比和PD以及治疗后6个月时的AL和BOP（+）%下降（P<0.05）。
使用牙周内窥镜进行SRP在改善牙周炎患者经过初始牙周治疗后残留牙周袋（PD≥5mm）的PD、AL和BOP方面显示出更好的效果，并且在提高该治疗的长期疗效方面具有优势。
