半导体激光辅助重度慢性牙周炎牙周非手术治疗的临床研究

目的: 评估半导体激光在辅助重度慢性牙周炎的牙周非手术治疗中发挥的作用。方法: 20例重度慢性牙周炎患者基线时进行牙周各项检查,包括探诊深度(probing depth, PD)、临床附着水平(Clinical attachment level, CAL)、出血指数(bleeding index, BI)、松动度(tooth mobility, MOB)。将患者的牙列分为左右两侧,右侧患牙为对照组,仅采用牙周非手术治疗;左侧患牙为实验组,先行牙周非手术治疗,再选取检查时重度慢性牙周炎的患牙,进行半导体激光的牙周袋消毒。治疗后8周对患者进行同样的牙周检查,比较牙周指标恢复情况。结果: 8周复查时两组的PD、CAL及BI均较基线时明显降低(P＜0.05);实验组PD和CAL的改善程度比对照组更明显(P＜0.05),治疗后的MOB无明显改善(P＞0.05)。结论: 半导体激光在辅助重度慢性牙周炎牙周非手术治疗时可以增加其疗效,能有效增加附着水平,它可能是对当前牙周非手术治疗方案的有效补充。

Effectiveness of Diode Laser as An Adjunct to Nonsurgical Treat Severe Chronic Periodontitis.

Objective: To evaluate the effectiveness of diode laser as an adjunct to nonsurgical periodontal treat severe chronic periodontitis. Methods: Twenty patients with severe chronic periodontitis were assessed by probing depth (PD), clinical attachment level (CAL), bleeding index (BI), and tooth mobility (MOB) at baseline. Dentition was divided into two sides. Teeth on the right side were set as the control group, which were accepted nonsurgical periodontal treatment. Teeth on the left side were set as the test group, which were accepted nonsurgical periodontal treatment at first, and whose periodontal pockets with severe chronic periodontitis were disinfected by diode laser later. The same periodontal examination was conducted at 8 weeks after the treatment. Results: The results showed that PD, CAL, and BI had a significant reduction in both groups at 8 weeks after the treatment (P＜0.05). PD and CAL showed a greater reduction in the test group than those in the control group (P＜0.05), while no significant difference was observed for MOB after the treatment (P＞0.05). Conclusion: Diode laser has additional benefits as an adjunct to nonsurgical periodontal treat severe chronic periodontitis for obtaining more attachment level. Diode laser might be an valuable supplement for the current nonsurgical periodontal treatment.
