摘要
目的:评价Nd:YAP激光用于牙周再生性手术的临床效果。方法:选择牙周基础治疗1个月后复查,PD≥6 mm,BOP(+),伴骨缺损的牙周炎患者48例,共60颗患牙,随机分为两组。实验组采用Nd:YAP激光联合牙周再生性手术进行治疗,对照组单纯采用牙周再生性手术治疗。对患者术后24 h、术后3 d的疼痛程度予以视觉模拟量表(VAS)记分评价,术前和术后6个月分别进行探诊深度(PD)、临床附着丧失(CAL)检查,比较2组术前、术后X线影像。采用SPSS 26.0软件包对数据进行统计学分析。结果:实验组术后24 h、术后3 d疼痛显著轻于对照组(P<0.001);术后6个月,2组患牙的PD、CAL水平均比术前显著减小(P<0.001)。2组术前PD、CAL组间比较无统计学差异,术后6个月实验组显著低于对照组(P<0.001)。X线片显示,术后6个月2组牙槽骨缺损区有不同程度的新骨形成影像。结论:Nd:YAP激光用于牙周再生性手术可减轻术后疼痛反应,提高手术疗效。
PURPOSE:To evaluate the clinical effect of Nd:YAP laser in periodontal regeneration surgery.METHODS:Four weeks after primary periodontal treatment,48 patients,60 teeth with bone defect and probing depth(PD)≥6 mm,bleeding on probing(BOP)(+),were randomly divided into two groups.Patients in the experimental group were treated with Nd:YAP laser combined with periodontal regeneration surgery,while patients in the control group were treated with conventional periodontal regeneration surgery alone.Visual analogue scale(VAS)score was used to evaluate the pain degree of patients 24 hours and 3 days after surgery.The probing depth(PD)and clinical attachment loss(CAL)were examined before and 6 months after surgery,and preoperative and postoperative X-ray images of the two groups were observed and compared.SPSS 26.0 software package was used for statistical analysis.RESULTS:Twenty-four hours and 3 days after surgery,the pain in the experimental group was significantly less than that in the control group(P<0.001),and PD and CAL levels in the two groups were significantly lower 6 months after surgery than before surgery(P<0.001).There was no significant difference in PD and CAL between the two groups before surgery,and the difference was statistically significant 6 months after surgery(P<0.001).X-ray images showed different degrees of new bone formation in alveolar bone defects in the two groups 6 months after surgery.CONCLUSIONS:The application of Nd:YAP laser in periodontal regeneration surgery can reduce postoperative pain and improve the surgical efficacy.
