摘要
目的评估Nd:YAG激光辅助龈下刮治术和根面平整术(SRP)在重度慢性牙周炎治疗中的疗效。方法重度慢性牙周炎纳入患者的牙齿分布在口内4个象限,牙周探诊深度(PD)5~8 mm,附着丧失(AL)≥5 mm,探诊出血(BOP)阳性。符合纳入标准的患者按照就诊顺序随机分为SRP组、SRP+L组(SRP后行Nd:YAG激光治疗)及L+SRP组(Nd:YAG激光治疗后行SRP)。记录各组在基线时与治疗8周时临床牙周指标BOP、PD和AL,并进行统计学分析。结果治疗后8周,各组的BOP、PD和AL较基线均有所改善(P<0.05)。SRP+L组和L+SRP组的BOP阳性率较SRP组明显减少(P<0.05)。SRP+L组的PD较SRP组和L+SRP组明显变浅(P<0.05),其中基线时PD=7 mm的位点,SRP+L组较SRP组和L+SRP组明显变浅(P<0.05)。SRP组较SRP+L组和L+SRP组的AL明显减少(P<0.05)。结论Nd:YAG激光辅助SRP治疗重度慢性牙周炎可以更好地减少BOP,使PD变浅,且SRP后进行Nd:YAG激光治疗对于较深的牙周袋PD减少更明显,但对AL的改善无优势。
Objective To evaluate the efficacy of Nd: YAG laser therapy adjunct to subgingival scaling and root planning(SRP) for treating severe chronic periodontitis. Methods We selected patients with severe chronic periodontitis whose teeth were distributed in 4 quadrants of the mouth, with probing depth(PD) of 5-8 mm, attachment loss(AL)≥5 mm and bleeding on probing(BOP). These teeth were randomly divided into three groups: SRP group, SRP+L group(Nd: YAG laser after SRP treatment), and L+SRP group(SRP after Nd: YAG laser treatment). We recorded parameters including BOP, PD and AL of the three groups at baseline and 8 weeks after treatment and made statistical analysis. Results At 8 weeks after treatment, BOP, PD and AL of the three groups were improved than those in the baseline(P<0.05). BOP positive percentage of SRP+L group and L+SRP group significantly reduced compared with SRP group(P<0.05). PD of SRP+L group significantly decreased compared with SRP group and L+SRP group(P<0.05), for sites with PD=7 mm, SRP+L group was significantly decreased compared with SRP and L+SRP groups(P<0.05).AL of SRP group significantly decreased compared with SRP+L group and L+SRP group(P<0.05).Conclusion Severe periodontal treatment with Nd:YAG laser adjunct to SRP is more effective in reducing BOP and PD,and for deeper pockets PD is significantly decreased in SRP+L group,but there is no advantage in the improvement of AL.
