Abstract：
OBJECTIVE: To compare the efficacy of three surgically assisted permanent anterior tooth eruption methods (laser surgery, electrosurgery and routine surgery) in children.
METHODS: Sixty-three orthodontic children with retarded permanent anterior tooth were selected and according to the random number table divided into three groups: laser surgery group (group A), electrosurgery group (group B) and routine surgery group (group C). The total operative time (min), the duration of pain after gingival excision (d), Visual Analogue Scale (VAS) pain intensity scores (0-10 cm), and gingival healing time (d) were all recorded. Six months after treatment, periodontal indexes of the three groups, including gingival indexes (GI), plaque indexes (PLI), probing depth (PD) were checked by the same periodontist and recorded.
RESULTS: Surgical records showed that compared with group C, there were statistically significant differences in operative time, pain duration, pain intensity and healing time in group A and B (P < 0.05). There was no significant difference in these four results between group A and group B. Periodontal examination indicators 6 months after surgery showed no statistical differences in GI, PLI and PD among group A, B and C. Oral clinical examination found that the three groups of patients with different treatment, dental eruption was normal.
CONCLUSIONS: All the three treatments can effectively solve the problem of delayed eruption of permanent anterior teeth in children. Particularly, laser surgery and high-frequency electrosurgery have good efficacy, little pain and high operability, which can be considered as a better method to aid teeth eruption.

摘要：
目的：比较三种手术辅助恒牙前牙萌出方法的疗效（激光手术，儿童的电外科和常规手术）。
方法：选择63例恒牙发育迟缓正畸儿童，按照随机数字表法分为3组：激光手术组（A组），电手术组(B组)和常规手术组(C组)。总手术时间(分钟),牙龈切除术后疼痛的持续时间（d），视觉模拟评分（VAS）疼痛强度评分（0-10cm），记录牙龈愈合时间(d)。治疗6个月后,三组牙周指数,包括牙龈指数(GI)，菌斑指数（PLI），由同一牙周病医生检查并记录探查深度（PD）。
结果：手术记录显示，与C组相比，手术时间差异有统计学意义，疼痛持续时间,A、B组疼痛强度及愈合时间差异有统计学意义(P<0.05)。术后6个月牙周检查指标A组与B组比较差异无统计学意义。A组PLI和PD,B和C.口腔临床检查发现,三组患者的治疗方法不同,牙疹是正常的。
结论：三种治疗方法均能有效解决儿童恒前牙延迟萌出的问题。特别是,激光手术和高频电手术都有很好的疗效，疼痛小，可操作性高，这可以被认为是一种更好的帮助牙齿萌出的方法。
