Er:YAG激光结合牙周翻瓣术治疗重度牙周炎的临床研究

The Clinical Research of Er:YAG Laser Combined with Periodontal Flap Surgery in Patients with Severe Periodontitis

目的:探讨Er:YAG激光结合牙周翻瓣术治疗重度牙周炎的临床效果。方法:选取2018年6月-2020年2月河北医科大学口腔医院牙周二科收治的60例重度牙周炎患者为研究对象,随机分为两组。对照组采用翻瓣术进行治疗,研究组在对照组的基础上采用Er:YAG激光辅助治疗,两组术后均随访6个月。比较两组术后6个月的临床疗效;对比两组术前、术后6个月的牙齿松动度及牙周指标,术后3d的疼痛程度及睡眠质量。结果:术后6个月,研究组总有效率高于对照组(90.00%vs 66.67%,P<0.05);两组术前、术后6个月的牙齿松动度比较,差异均无统计学意义(P>0.05)。与术前比较,术后6个月,两组PD、PLI、SBI均降低,且研究组均低于对照组(P<0.05);术后3d,研究组VAS、PSQI评分均低于对照组(P<0.05)。结论:Er:YAG激光结合牙周翻瓣术可明显改善重度牙周炎患者的牙周指标,促进组织愈合,减轻术后疼痛,提高睡眠质量,进而有助于提高临床疗效,且对牙齿松动度的影响较小。

Objective To investigate the clinical research of Er:YAG laser combined with periodontal flap surgery in patients with severe periodontitis.Methods Between June 2018 and February 2020,60 patients with severe periodontitis admitted to the department of oral dentistry,Stomatological Hospital of Hebei Medical University were selected as the research objects.They were divided into the study group and the control group through a random number table,with 30 cases in each group.The control group was treated with periodontal flap surgery,and the study group was treated with Er:YAG laser on the basis of the control group.Both groups were followed up for 6 months after surgery.The clinical efficacy at 6 months after surgery was compared between the two groups,the teeth looseness and periodontal indicators before and 6 months after surgery,the pain degree and the quality of sleep 3 d after surgery were compared between the two groups.Results At 6 months after surgery,the total effective rate in the study group was higher than the control group(90.00%vs 66.67%,P<0.05).There was no significant difference in teeth looseness between the two groups before and 6 months after surgery(P>0.05).Compared with before surgery,at 6 months after surgery,the PD,PLI,and SBI in the two groups decreased,and the study group were lower than the control group(P<0.05).At 3 d after surgery,the VAS and PSQI scores in the two groups decreased,and the study group were lower than the control group(P<0.05).Conclusion Er:YAG laser combined with periodontal flap surgery could significantly improve the periodontal indicators of patients with severe periodontitis,promote tissue healing,reduce postoperative pain,improve sleep quality,and thus help improve the clinical efficacy,and has little effect on teeth looseness.
