摘要
目的观察并比较两种不同波长激光与龈下洁刮治联合治疗重度牙周炎的临床效果。方法选择2017年1—6月就诊的重度牙周炎患者20例,采用分口设计,患者口腔4个象限随机分为g1组对照组(仅进行传统牙周基础治疗,即超声加手工龈下刮治、根面平整),g2组(传统牙周基础治疗加Nd:YAG激光牙周袋外照射),g3组(传统牙周基础治疗加Nd:YAG激光牙周袋内照射)和g4组(传统牙周基础治疗加Er:YAG激光牙周袋内照射)。分别于基线、治疗后4周、8周和12周进行牙周临床指标检查,内容包括牙周袋探诊深度(probing depth,PD)和附着丧失(attachment loss,AL)。结果治疗后4组的PD和AL均较基线时有所改善。第4周时,4组间PD和AL差异没有统计学意义(P>0.05)。第8周时激光治疗组(g2、g3、g4组)PD和AL治疗的效果较对照组(g1组)明显,差异具有统计学意义(P<0.05);各激光治疗组间未有明显差异。第12周时PD结果同第8周;AL的改善结果为激光治疗组较对照组更明显,差异具有统计学意义(P<0.05);g4组(即Er:YAG激光袋内照射)AL的改善效果优于g2组和g3组(即Nd:YAG激光袋外照射和袋内照射);g2组和g3组(即Nd:YAG激光袋外照射和袋内照射)相比没有显著差异(P>0.05)。结论激光与龈下洁刮治联合治疗重度牙周炎效果明显优于单独洁刮治治疗,两种激光在PD的改善方面不存在明显差异。Er:YAG激光在AL的改善方面优于Nd:YAG激光,Nd:YAG激光袋内外照射无明显差异,可在临床中推广应用。
Objective To investigate the clinical effects of the treatment of severe periodontitis with two different wave length lasers and conventional periodontal therapies. Methods Twenty systemically healthy patients with severe chronic periodontitis were selected for this study. The quadrants were randomly allocated in a split-mouth design into four groups-Group 1（ served as the control,treated with ultrasonic and manual scaling and root planning,SRPU）,Group 2（ SRPU combined with Nd： YAG laser,outside mode）,Group 3（ SRPU combined with Nd： YAG laser,inside mode） and Group 4（ SRPU combined with Er： YAG laser,inside mode）. Clinical parameters,including probing depth（ PD） and clinical attachment loss（ AL） were recorded at baseline,4 weeks,8 weeks and 12 weeks after treatment. Results The clinical parameters had significantly improved in all groups after treatment. No significant differences among the four groups were observed in PD and AL in 4 weeks（ P〈0.05）. There were statistically significant differences in PD and AL between the laser treated groups（ Group 2,3,4） and control group（ Group 1） in 8 weeks（ P〈0.05）,and no significant differences were found among laser treated groups（ P〈0.05）. In 12 weeks,there were statistically significant differences in PD and AL between the laser treated groups（ Group2,3,4） and control group（ Group 1）（ P〈0.05）. There was no significant difference in PD among laser treated groups（ P〈0.05）. However,there were significant differences in AL between Er： YAG laser treated group（ Group 4） and Nd： YAG laser treated groups（ Group 2,3）（ P〈0.05）. No significant differences were observed between Group 2 and Group 3（ P〉0.05）. Conclusions The present study suggests that a combined course of Er： YAG or Nd： YAG laser therapy is better in the treatment of severe periodontitis. Er： YAG laser therapy may be beneficial particularly in the improvement of AL on a short-term basis. Furthermore,well-designed
