摘要:

目的 探究使用光动力疗法(photodynamic therapy,PDT)辅助机械性龈下清创(mechanical debridement,MD)治疗种植体周炎(peri-implantitis)的短期临床疗效。方法 根据2018牙周病新分类标准,纳入临床上诊断为种植体周炎的单颗种植体(单冠修复)患者,治疗前记录种植体周探诊深度(probing depth,PD)、改良龈沟出血指数(modified sulcus bleeding index,mSBI)和改良菌斑指数(modified plaque index,mPLI),以mSBI≥1的位点作为治疗位点。MD组为对照组,仅对治疗位点行机械性龈下清创;PDT组为治疗组,在龈下清创后即刻和治疗后1周,共行两次辅助性光动力治疗。结束治疗后6周、12周复查,检查所纳入患者种植体治疗位点的PD、mSBI和mPLI的变化。结果 本研究共纳入35例患者,发生种植体周炎的植体38枚,共计154个治疗位点。PDT组和MD组各纳入20枚和18枚植体,其中PDT组纳入治疗位点共78个,PD≥6 mm的位点共51个,PD<6 mm的位点共27个;对照组纳入治疗位点共76个,PD≥6 mm的位点共53个,PD<6 mm的位点共23个。基线时两组的PD、mSBI和mPLI均无统计学差异,治疗后6周及12周复查时,两组各临床指标与基线相比均获得显著改善(P<0.05),其中PDT组治疗后6周的mSBI显著低于MD组(P<0.05)。在PD≥6 mm的位点中,PDT组的mSBI在治疗后6周、12周复查时均显著低于MD组(P<0.05)。PDT组和MD组在12周复查时达到治疗终点的植体百分比分别为70.00%和55.56%,无统计学差异(P>0.05)。结论 光动力疗法辅助机械清创可以有效治疗种植体周炎,是一种安全有效的辅助治疗手段,对改善深种植体周袋(PD≥6 mm)的炎症以及mSBI具有显著疗效。

Abstract:

Objective To evaluate the short-term clinical efficacy of photodynamic therapy (PDT) assisted mechanical debridement (MD) in the treatment of peri-implantitis. Methods According to the new international classification of periodontal diseases and peri-implant diseases in 2018, single tooth implants diagnosed as peri-implantitis were included. Before treatment, the probing depth (PD), modified sulcus bleeding index (mSBI), and modified plaque index (mPLI) were recorded as the baseline, with mSBI ≥ 1 sites as the treatment sites. The MD group was a control group, and only mechanical subgingival debridement was performed. The PDT group was treated with photodynamic therapy twice, immediately after subgingival debridement and one week after. Follow-up was arranged at 6 and 12 weeks after the end of treatment to examine the changes in PD, mSBI, and mPLI at the included implant treatment sites. Results A total of 35 patients were included in this study, with 38 teeth affected by peri-implantitis and 154 treatment sites. The PDT group and MD group included 20 and 18 implants respectively, with a total of 78 treatment sites included in the PDT group, 51 sites with PD ≥ 6 mm, and 27 sites with PD<6 mm. A total of 76 treatment sites were included in the MD group, including 53 sites with PD ≥ 6 mm and 23 sites with PD<6 mm. At baseline, there was no statistically significant difference in PD, mSBI, and mPLI between the two groups. At 6 and 12 weeks after treatment, there were statistically significant differences in clinical indicators between the two groups compared to baseline (P<0.05). Among them, the mSBI in the PDT group was significantly lower than that in the MD group at 6 weeks after treatment (P<0.05). At sites with PD ≥ 6 mm, the mSBI of the PDT group was significantly lower than that of the MD group at 6 and 12 weeks after treatment (P<0.05). The number of implants in the PDT group and MD group that reached the treatment endpoint at 12 weeks follow-up was 70.00% and 55.56%, respectively, and there was no difference between the two groups (P>0.05). Conclusion Photodynamic therapy assisted with mechanical debridement can effectively treat peri-implantitis and is a safe and effective auxiliary method, and has significant therapeutic effects on inflammation control and improvement of mSBI in those sites with PD ≥ 6 mm.
