Er,Cr:YSGG激光在口腔疾病治疗中的应用进展
Er,Cr:YSGG激光 口腔修复 口腔种植 口腔颌面外科手术
2020/1/21
Er,Cr:YSGG激光是一种新型水动力生物激光系统,又称水激光,具有方向性好、单色性好、亮度高、强度大等特点。Er,Cr:YSGG激光的波长与水和羟基磷灰石的吸收峰值相近,可以很好地被口腔组织吸收,其生物刺激效应有助于创伤组织的修复和再生。其具有高效的杀菌作用、精确的切割能力和止血凝固等优势,已在口腔临床的各方面推广,在口腔内科、口腔修复、口腔种植及口腔颌面外科手术方面均有广泛应用,在某些领域具...
Er,Cr:YSGG水激光在慢性根尖周炎治疗中的应用
水激光 慢性根尖周炎 根管消毒
2018/5/25
探讨水激光在慢性根尖周炎治疗中的效果。方法 230颗慢性根尖周炎患牙,随机分成三组:A组76颗患牙采用水激光根管消毒后热牙胶垂直加压技术充填;B组76颗患牙采用水激光根管消毒后封氢氧化钙根管消毒糊剂1周后热牙胶垂直加压技术充填;C组78颗患牙采用根管预备后封氢氧化钙根管消毒糊剂1周后热牙胶垂直加压技术充填。根充后1周,1年分别复诊,观察疗效。结果 根管充填术后1周复查,出现根管治疗术后急症病例比例...
目的：探讨应用RFPT5-14工作尖的Er, Cr: YSGG激光照射对牙周炎患牙及健康牙根面微观结构改变以及粗糙度的影响。方法：选取8颗因牙周炎拔除的患牙，用超声刮治器去除根面牙石，另选取8颗因正畸减数或阻生智齿拔除的健康牙，将每颗牙根面分为4个区域，对应为1~4组，分别进行如下4种处理：（1）不处理；（2）Gracey刮治器进行根面平整30 s；（3）低功率激光照射30 s；（4）高功率激光照...
