摘要

目的: 探讨Nd:YAG激光、Er:YAG激光及传统牙龈切除术治疗正畸中牙龈增生的临床疗效差异。方法: 将34例正畸患者的270颗牙龈增生前牙, 随机分为三组, 分别采用Nd:YAG激光、Er:YAG激光及传统牙龈切除术治疗, 比较其术前、术后24 h的疼痛指数(VAS)均值, 以及术前、术后4、12、24周的龈增生指数(GHI)、探诊深度(PD)、出血指数(BI)及菌斑指数(PLI), 对三种治疗方法的临床疗效进行评估。结果: 术后24 h, Nd:YAG激光切除组、Er:YAG激光切除组的VAS明显低于传统手术切除组, 差异有统计学意义(P<0.05); 三种方法的术后4、12、24周的各项指标均低于术前, 且Nd:YAG激光切除组和Er:YAG激光切除组均明显低于传统手术切除组, 差异有统计学意义(P<0.05)。结论: Nd:YAG激光、Er:YAG激光疗法均优于传统手术切除法, 且Nd:YAG激光的止血效果最佳, Er:YAG激光的抑菌效果最佳。

Abstract

Objective: To investigate the clinical efficacy of Nd:YAG laser, Er:YAG laser and traditional gingival resection in the treatment of gingival hyperplasia in orthodontics. Methods: 34 cases of orthodontic patients with 270 gingival hyperplasia of anterior teeth were randomly divided into three groups and treated with Nd:YAG laser, Er:YAG laser and traditional gingival resection respectively. The treatment of 24 h mean pain index (VAS)were compared before and after surgery and the preoperative and postoperative 4, 12 and 24 weeks Gingival hyperplasia index(GHI), probing depth(PD), bleeding index(BI)and plaque index(PLI), the clinical efficacy of the three treatments was evaluated. Results: 24 h after operation, the VAS of Nd:YAG laser, Er:YAG laser resection group was significantly lower than that of traditional surgical resection group, the difference was statistically significant (P< 0.05); three methods of postoperative index 4, 12 and 24 weeks were lower than those before operation, and the Nd:YAG laser resection group and Er:YAG laser resection group was significantly lower than that of traditional surgical resection group, the difference was statistically significant(P<0.05). Conclusion: The Nd:YAG laser and Er:YAG laser therapy are superior to the traditional surgical resection, and the Nd:YAG laser has the best hemostatic effect, and the Er:YAG laser has the best antibacterial effect.
