摘要/Abstract

摘要： 目的: 评估Er:YAG激光应用于磨牙-切牙矿化不全的临床疗效。方法: 纳入2021年1~12月于我科就诊的8~16岁儿童的68颗磨牙-切牙矿化不全。使用计算机软件将同一患儿口内不同位置的患牙随机分为实验组和对照组。实验组:Er:YAG激光去腐备洞及窝洞表面处理;对照组:传统涡轮机去腐备洞,两组均使用树脂充填。术中及术后13周、26周、52周参照面部表情疼痛量表、改良世界牙科联盟标准评估两组患牙的临床疗效。结果: 术中无痛或少许疼痛儿童的比例实验组(73.53%)高于对照组(44.12%,χ²=6.071,P＜0.05);术后13周,敏感性方面的成功率实验组(100.00%)高于对照组(82.35%),两组差异有统计学意义(χ²=4.570,P＜0.05);术后52周,边缘适合性方面的成功率实验组(91.18%)高于对照组(70.59%),继发龋、腐蚀、崩解方面的成功率实验组(94.12%)高于对照组(73.53%),两组差异均有统计学意义(χ²=4.660,5.314,P＜0.05)。结论: Er:YAG激光治疗磨牙-切牙矿化不全,能有效减轻患儿术中疼痛、提高树脂充填体成功率,为儿童口腔疾病的微创治疗提供新思路。

Abstract: Objective: To evaluate the clinical efficacy of Er:YAG laser in the treatment of molar incisor hypomineralization (MIH). Methods: From January to December 2021, 68 MIH children aged 8-16 from Pediatrics Dentistry Department, Hefei Stomatological Hospital were included. By using computer software, different teeth of the same child were randomly divided into two groups, the experimental group and the control group. The experimental group used Er:YAG laser to remove the caries, prepare the cavity, and deal with surface of the teeth. The control group used a traditional turbine to remove the caries and prepare the cavity. MIH of both groups were filled with resin. The clinical efficiency of two groups were evaluated according to the Wong-Baker Face Pain Rating Scale (WBFPRS) and the modified World Dental Federation (FDI) Criteria during the operation and 13 weeks, 26 weeks and 52 weeks after the operation. Results: In the operation, the percentage of children with no pain or little pain in the experimental group (73.53%) was significantly higher than that of the control group (44.12%, P＜0.05). At 13 weeks after operation, the success rate of sensitivity in the experimental group (100.00%) was higher than that of the control group (82.35%, P＜0.05). At 52 weeks after operation, the success rate of marginal fitness in the experimental group (91.18%) was significantly higher than that of the control group (70.59%), and the success rate of recurrence of caries, erosion, and abfraction of the experimental group (94.12%) was significantly higher than that of the control group (73.53%, P＜0.05). Conclusion: Er:YAG laser in the treatment of MIH can effectively reduce intraoperative pain and improve the success rate of resin restorations, which provides a new idea for minimally invasive treatment of children's oral diseases.
