To evaluate the effects of local-delivery of 25% metronidazol gel and mechanical cleaning using ultrasonic carbon fiber tip on dental implants with peri-implantitis.
27 implants with peri-implantitis were randomly assigned to receiving either 25% metronidazol gel treatment or carbon fiber tip ultrasonic scaling. All parameters including plaque index (PLI), probing depth (PD) of pocket, sulcular bleeding index (SBI), and BANA enzyme analysis were measured at baseline, 1, 2, 6 and 12 weeks after treatment.
Statistically significant decrease (P < 0.05) in SBI, BANA test and PLI occurred in both treatment groups at all time intervals compared to baseline. PD had a decreasing tendency in both groups, but only metronidazole group reached statistically significant level (P < 0.05) at 2 and 6 week intervals compared to baseline. None of the treatment modalities produced any side effects on the implant and peri-implant tissues.
Both 25% metronidazol gel and mechanical cleaning using ultrasonic carbon fiber tip can be safely and effectively used in the treatment of peri-implant diseases.
评估局部递送25%甲硝唑凝胶及使用超声碳纤维头进行机械清洁对患有种植体周围炎的牙种植体的影响。
将27颗患有种植体周围炎的种植体随机分为两组，分别接受25%甲硝唑凝胶治疗或碳纤维头超声洁治。在治疗前、治疗后1周、2周、6周和12周测量所有参数，包括菌斑指数（PLI）、牙周袋探诊深度（PD）、龈沟出血指数（SBI）和BANA酶分析。
与基线相比，两个治疗组在所有时间点的SBI、BANA检测和PLI均有统计学意义的显著下降（P < 0.05）。两组的PD均有下降趋势，但仅甲硝唑组在治疗后2周和6周时与基线相比达到统计学显著水平（P < 0.05）。两种治疗方式均未对种植体及种植体周围组织产生任何副作用。
25%甲硝唑凝胶和使用超声碳纤维头进行机械清洁均可安全有效地用于治疗种植体周围疾病。
