摘要: 目的:评价不同能量参数的Er:YAG激光对早期种植体周围炎照射后的临床疗效及厌氧菌含量的变化。方法:纳入90例早期种植体周围炎患者,采用随机数字表法分A、B、C、D四组,记录基线值:菌斑指数(plaque index,PLI)、出血指数(bleeding index,BI)、探诊深度(probing depth,PD)、骨缺损深度(defect depth,DD)。A、B、C三组分别用40、60、80mj的Er:YAG激光进行照射;术中用视觉模拟评分法(visual analogue scale,VAS)记录患者疼痛程度;D组用盐酸米诺环素。临床治疗1次/周,治疗3次。比较第8周临床总疗效。收集治疗前、激光照射及D组洁刮治后各患牙龈沟液进行厌氧菌培养并对其含量进行分析。结果:各组第8周时临床总有效率未见明显差异(P>0.05),细菌含量变化(P<0.05)有统计学意义。结论:在安全范围内,第8周时不同能量参数的Er:YAG激光对早期种植体周围炎的临床总有效率差异不明显,但其微生物变化差异显著,且随着激光能量的增高其杀菌性越强。

Abstract: Objective: To evaluate the clinical efficacy and anaerobic bacteria content of Er:YAG laser irradiation with different energy parameters on early peri-implantitis. Methods: 90 patients with early peri-implantitis were included, who were randomly devided into four groups A, B, C, and D. Baseline values were recorded: plaque index (PLI), bleeding index (BI), probing depth (PD), and defect depth (DD). A, B and C groups were irradiated with Er:YAG laser at 40mj, 60mj, and 80mj, respectively. The degree of pain was recorded by visual analogue scale (VAS) during operation. Group D was treated with minocycline hydrochloride. Clinical treatment was 1 time per week for 3 times. The total clinical efficacy after the 8 weeks were compared. Gingival crevicular fluid for each tooth was collected to culture and analyze the content of anaerobic bacteria before treatment, after laser irradiation, and after scaling. Results: There was no significant difference in the rate of total clinical effective after 8 weeks for each group (P>0.05), but the change of bacterial content for each group was statistically significant (P<0.05). Conclusion: Among the safety range, the rate of total clinical effective for Er:YAG laser with different energy parameters on early peri-implantitis was not obvious after 8 weeks. However, the microbial changes were significant, and as the laser energy increasing, the bactericidal property was stronger.
