摘要/Abstract

摘要： 目的:评价Er:YAG激光联合渗透树脂治疗乳牙氟斑牙的效果。方法:选择2019年1月—2024年1月在河北医科大学口腔医院进行乳牙氟斑牙治疗的患儿86例,采用随机数字表法分为对照组（43例,患牙92颗）与试验组（43例,患牙116颗）。对照组采用皓齿 Opalustre 微研磨糊剂联合渗透树脂治疗,试验组采用Er:YAG激光联合渗透树脂治疗。统计两组患儿临床资料,比较治疗前、治疗后1周及治疗后3个月牙面色阶变化、漂白效果和着色点脱色率变化,比较两组满意度及牙敏感发生率。结果:治疗1周及3个月后,试验组牙面色阶分别为3.42±0.51和3.86±0.62,显著低于对照组的5.82±0.75和7.23±1.02（P<0.05）;试验组漂白总有效率均为100.00%,显著高于对照组的94.57%和84.78%（P<0.05）;试验组着色点脱色率为95.73%,显著高于对照组的88.13%（P<0.05）。试验组术后2 h、12 h、1 d疼痛视觉模拟评分（visual analog scoring,VAS）显著低于对照组（P<0.05）。试验组治疗满意率为96.55%,显著高于对照组的64.13%（P<0.05）。试验组术后2 h、1周、3个月的牙敏感发生率分别为3.45%、5.17%和6.03%,显著低于对照组的15.22%、22.83%和28.26%（P<0.05）。结论:Er:YAG激光联合渗透树脂治疗乳牙氟斑牙较传统微研磨糊剂联合渗透树脂更优越,不仅有效改善牙美观,还能减少治疗后牙敏感,提高患者满意度。

Abstract: PURPOSE: To evaluate the efficacy of Er:YAG laser combined with infiltration resin in the treatment of dental fluorosis of deciduous teeth. METHODS: Eighty-six children treated for deciduous fluorosis teeth at Hebei Medical University Dental Hospital from January 2019 to January 2024 were selected and randomly divided into the control group (n=43, 92 teeth) and experimental group(n=43, 116 teeth). The control group was treated with Opalustre micro-abrasion paste combined with infiltration resin, while the experimental group was treated with Er: YGA laser combined with infiltration resin. Clinical data of both groups were collected, changes in tooth shade, whitening effects and the rate of discoloration removal at baseline, 1 week and 3 months post-treatment were compared. Treatment satisfaction and the incidence of tooth sensitivity were also compared between the two groups. RESULTS: One week and three months post-treatment, the tooth shade scores in the experimental group were 3.42±0.51 and 3.86±0.62, respectively, significantly lower than those in the control group (5.82±0.75 and 7.23±1.02, P<0.05). The total effective whitening rate in the experimental group was 100.00% at both one week and three months post-treatment, significantly higher than that in the control group(94.57% and 84.78%, P<0.05). The rate of discoloration removal in the experimental group was 95.73%, significantly higher than that in the control group (88.13%, P<0.05). The VAS scores for post-operative pain at 2, 12 hours and 1 day in the experimental group were significantly lower than those in the control group(P<0.05). The treatment satisfaction rate in the experimental group was 96.55%, significantly higher than that in the control group (64.13%, P<0.05). The incidence rates of post-operative tooth sensitivity at 2 hours, 1 week and 3 months in the experimental group were 3.45%, 5.17% and 6.03%, respectively, significantly lower than those in the control group(15.22%, 22.83% and 28.26%, P<0.05). CONCLUSIONS: Er:YGA laser combined with infiltration resin demonstrats superior treatment efficacy for deciduous fluorosis teeth compared to the traditional combination of micro-abrasion paste and infiltration resin. It not only effectively improves dental aesthetics, but also reduces dental sensitivity after treatment, and improves patient satisfaction.
