[摘要]目的：研究分析Er，Cr：YSGG激光去腐对低龄儿童牙科畏惧疼痛程度及治疗成功率的影响。方法：收集2018年1月-2018年12月于笔者医院儿童口腔科初次就诊的低龄龋齿患儿100例，根据电脑随机分组法分为两组施行对照研究，常规组予以传统涡轮机去腐，研究组予以激光去腐，每组50例。观察两组治疗时间，治疗期间患儿的畏惧疼痛程度及治疗成功率。 结果：研究组治疗时间短于常规组（P<0.05），研究组治疗期间畏惧疼痛程度低于常规组（P<0.05）;研究组治疗成功率高于常规组（P<0.05）。结论：对于低龄龋齿患儿，Er，Cr∶YSGG激光去腐较传统涡轮机去腐的治疗成功率高，并且可以减轻患儿畏惧疼痛程度、缩短治疗时间，值得在临床推广应用。

Abstract：Objective  To study and analyze the Er，Cr∶YSGG laser effect of dental fear and success rate of treatment on early childhood caries. Methods  from January 2018 to December 2018，100 children with early childhood caries received by pediatric stomatology department were taken as the observation subjects in this study. According to the computer， they were respectively randomly divided into 2 groups， one group was named routine group， and the other group was named study group. 50 cases in each group. The duration of treatment， the degree of fear and pain and the success rate of  treatment were observed. Results  The treatment time of the study group were shorter than those of the routine group （P<0.05），The fear and pain degree of the study group during the treatment were lower than those of the routine group （P<0.05）. The treatment success rate of the study group was higher than that of the routine group. Conclusion  Compared with traditional turbine decaying， laser decaying is more successful in the treatment of children with early childhood caries， and it can also reduce children's fear and pain. It has the advantages of simple operation， short treatment time， and it is worthy of wide application in the clinical therapy.

第四次全國口腔健康流行病学调查结果显示，5岁儿童乳牙患龋率达到70.9%，较之前呈上升趋势[1]。低龄儿童龋（ECC）是影响患儿日常生活及身心健康发育的常见病，同时也增加了恒牙的患龋风险[2]。既往临床对于龋齿患儿的治疗通常以传统涡轮机去腐为主，在备洞期间，噪音大、震动幅度明显，去腐期间容易过量去除正常的牙体组织，且去腐时患儿疼痛感明显，必要时需局麻，造成大多数患儿比较畏惧，拒绝或阻碍治疗的顺利进行[3]。近年来，微创治疗和无痛治疗越来越受到儿童口腔医生的青睐，目前激光去腐疗法因为安全、无痛、创伤小等优势，在临床口腔科中得到了广泛应用[3]。Er，Cr∶YSGG激光是近年来研制的液体动力激光系统，1998年美国食品药物管理局（FDA）首次批准Er，Cr：YSGG激光可应用于牙体硬组织治疗[4]，Er，Cr∶YSGG激光能够快速被组织内水分所吸收，通过“微爆炸”作用，靶组织予以完全去除，进而为充填提供有利条件[5]。……
