摘要: 目的

分析Nd∶YAG激光照射辅助牙周再生术治疗牙周炎伴磨牙根分叉病变患者的临床疗效,为Nd∶YAG激光照射治疗该类疾病提供依据。

方法

选取于本院牙周黏膜科门诊就诊的76例接受牙周再生术治疗的牙周炎伴磨牙根分叉病变患者作为研究对象,分为单纯行牙周组织再生术治疗组(对照组)和Nd∶YAG 激光照射辅助牙周组织再生术治疗组(实验组),每组38例。2组患者均接受牙周再生术,实验组患者术中采用Nd∶YAG激光处置根分叉区。对比2组患者术前、术后6个月和术后12个月时牙周探诊深度(PPD)、垂直附着丧失(CAL-V)、水平附着丧失(CAL-H)、出血指数(BI)和根分叉水平探入深度(HPD),采用锥形束CT(CBCT)测量患者的垂直骨丧失(BL-V)和水平骨丧失(BL-H),计算咀嚼效率。

结果

2组患者术前PPD、CAL-V、CAL-H、BI、BL-V和BL-H比较差异均无统计学意义(P>0.05);与术前比较,术后6和12个月时2组患者PPD、CAL-V、CAL-H、BI、HPD、BL-V和BL-H均呈下降趋势,且术后实验组患者上述指标均明显低于对照组(P<0.05)。2组患者术前咀嚼效率比较差异无统计学意义(P>0.05);与术前比较,术后6和12个月时2组患者咀嚼效率呈升高趋势,且术后实验组患者咀嚼效率高于对照组(P<0.01)。

结论

在牙周炎伴磨牙根分叉病变患者的牙周再生术治疗中,采用Nd∶YAG 激光照射辅助治疗,可有效增强牙周再生术治疗效果,减轻牙周炎症,促进牙周组织愈合,有助于改善患者的咀嚼功能。

Abstract: Objective

To analyze the clinical efficacy of neodymium yttrium aluminum garnet (Nd∶YAG) laser assisted periodontal regeneration in the treatment of the patients with periodontitis and molar furcation lesions,and to provide basis for the treatment of this disease with ND∶YAG laser.

Methods

A total of 76 patients with periodontitis and molar root bifurcation who were treated by periodontal regenerative surgery were selected as the subjects. They were divided into simple periodontal tissue regeneration group (control group) and Nd∶YAG laser irradiation-assisted periodontal tissue regeneration surgery group(experimental group), with 38 cases in each group. The patients in two groups underwent conventional guided tissue regeneration, and the patients in experimental group received Nd∶YAG laser to treat the root bifurcation area during the operation. The periodontal probing depth (PPD), vertical attachment loss (CAL-V), horizontal attachment loss (CAL-H), bleeding index (BI),and the horizontal penetration depth of root bifurcation (HPD) before surgery, 6 months after surgery and 12 months after surgery of the patients were compared between two groups; the values of vertical bone loss (BL-V) and horizontal bone loss (BL-H) were measured by cone beam CT (CBCT).

Results

There were no significant differencs in PPD, CAL-V, CAL-H, BI, BL-V and BL-H of the patients between two groups before surgery (P>0.05);compared with before surgery,PPD, CAL-V, CAL-H, BI, HPD, BL-V, BL-H of the patients in two groups all showed a downward trend at 6 and 12 months after surgery; the above indicators in experimental group at 6 and 12 months after surgery were significantly lower than those in control group (P<0.05). There was no statistical difference in the chewing efficiency of the patients between two groups before surgery (P>0.05).Compared with before surgery, at 6 and 12 months after surgery, the chewing efficiencise of the patients in two groups had a increasing trend; the chewing efficiencies in experimenyal group were higher than those in control group at 6 and 12 months after surgery (P<0.01).

Conclusion

In the periodontal regeneration surgical treatment of the patients with periodontitis and molar root bifurcation lesions, the use of Nd∶YAG laser adjuvant treatment can effectively enhance the treatment effect of periodontal regenerative surgery, reduce the periodontal inflammation,promote the periodontal tissue healing,and improve the chewing function of the patients.
