摘要： 目的 探讨PIPS-Er: YAG激光技术（光子激活光声流）治疗后根管壁牙本质失水状况及对牙根抗压强度的影响。方法 选取2018年7—9月南京市口腔医院口腔颌面外科门诊拔除的120颗健康正畸减数牙（单根牙）进行离体牙实验,按随机数字表法将其均分为A组（PIPS-Er: YAG激光冲洗组）、B组（注射器冲洗组）、C组（超声荡洗组）和D组（空白对照组,未治疗）,比较治疗后各组根管壁牙本质失水状况和治疗前后牙根抗压强度的差异。结果 1）A~D组内各标本根管上、中、下段根管壁牙本质含水量依次递增,但差异无统计学意义（P>0.05）;根管壁上段：A、C组低于B、D组（P<0.05）,A组略低于C组（P>0.05）,B组低于D组（P<0.05）;根管壁中段：A组低于B~D组（P<0.05）,A组略低于C组（P>0.05）,B组低于D组（P<0.05）;根管壁下段：A组低于B~D组（P<0.05）、A组略低于C组（P>0.05）,B组低于D组（P<0.05）。2）A、B、C组与D组间的抗压强度差异无统计学意义（P>0.05）。结论 使用Er：YAG激光PIPS技术能降低根管壁牙本质的含水量,且不会降低牙根的抗压强度,有良好的临床应用前景。

Abstract: Objective This work aims to investigate the effects of photon-activated photoacoustic flow (PIPS) Er: YAG laser on root compressive strength and the water loss of the root canal wall dentin.Methods A total of 120 healthy orthodontic subtraction teeth extracted from the Department of Oral and Maxillofacial Surgery from July 2018 to September 2018 were randomly assigned into the following four groups using the random number table method: group A (PIPS Er:YAG laser washing group), group B (syringe washing group), group C (ultrasonic wave washing group), and group D (control group, untreated). Differences in the water content of root canal wall dentin and compressive strength of root before and after treatment were observed.Results The water content of the dentin of upper, middle, and lower root canals increased in all groups, but no significant difference was observed (P>0.05). In the upper segment of root canal wall, the water content of groups A and C was lower than that of groups B and D (P<0.05). In particular, that of group A was lower than that of group C (P>0.05), and that of group B was lower than that of group D (P<0.05). In the middle segment of the root canal wall, the water content of group A was lower than that of groups B, C, and D (P<0.05). In particular, that of group A was lower than that of group C (P>0.05), and that of group B was lower than that of group D (P<0.05). In the lower segment of root canal wall, the water content of group A was lower than that of groups B, C, and D (P<0.05). In particular, that of group A was slightly lower than that of group C (P>0.05), and that of group B was lower than that of group D (P<0.05). All groups had no significant difference in compressive strength (P>0.05).Conclusion Er: YAG laser PIPS technology can remarkably reduce the water content of dentin in the root canal wall but not the compressive strength of the root. Hence, this method has a good clinical application prospect.

Key words: Er: YAG laser, photon-activated photoacoustic flow, dentin of root canal wall, compressive strength
