摘要/Abstract

摘要： 目的: 探究光学相干断层扫描成像技术(optical coherence tomography,OCT)在氟斑牙诊断与树脂渗透治疗疗效评价中应用的可行性。方法: 选择2023年7月至2024年6月就诊于徐州市中心医院口腔科的20例氟斑牙患者为实验组,20例健康人群为对照组。对照组11、21行OCT扫描,实验组患者15-25、35-45行“微研磨+诊室漂白+17%乙二胺四乙酸 (ethylene diamine tetraacetic acid, EDTA)预处理+树脂渗透”的微创漂白治疗,通过分析治疗前、树脂渗透后即刻和6个月随访的入组人群牙齿OCT图像数据、白斑面积测量、色阶变化和氟斑牙牙面指数评分(TSIF评分)等指标,综合评价氟斑牙美学治疗效果。结果: 治疗前对照组OCT图像釉质表面平整、釉柱形态清晰,灰度值和高亮层厚度显著高于实验组(P＜0.05)。经漂白联合渗透治疗后,氟斑牙患者在OCT图像高亮层厚度、灰度值、白斑面积、TSIF评分和色阶变化等方面均显著改善(P＜0.05)。结论: 诊室漂白联合渗透树脂治疗可有效改善氟斑牙美学效果,且近期疗效稳定;OCT无创扫描可作为氟斑牙诊断与疗效评价的方法。

Abstract: Objective: To explore the feasibility of optical coherence tomography (OCT) in the diagnosis of dental fluorosis and evaluation of the resin infiltration efficacy through clinical research. Methods: Twenty patients with dental fluorosis who visited the Department of Stomatology of Xuzhou Central Hospital from July 2023 to June 2024 were selected as the experimental group, and twenty healthy individuals were selected as the control group. The upper central incisors in the control group underwent OCT scanning. All the incisors and premolars in both maxillary and mandibular arches of the patients in the experimental group were applied minimally invasive enamel whitening therapy comprising microabrasion, in-office bleaching, 17% ethylene diamine tetraacetic acid (EDTA) pretreatment, and resin infiltration technique. The aesthetic treatment effectiveness of dental fluorosis was comprehensively evaluated by analyzing the OCT image data of the enrolled population's teeth, measuring the area of white spots, evaluating the color shade changes, and tooth surface index of fluorosis (TSIF) scores before treatment, immediately after resin infiltration, and the 6-month follow-up. Results: In the control group, the enamel surfaces in the OCT images were smooth, the enamel rods were clear, and the gray values and the thicknesses of the high-brightness layers were significantly higher than those in the experimental group (P<0.05). After bleaching combined with resin infiltration treatment, the aesthetic efficacy of the patients with dental fluorosis showed significant improvements in the thicknesses of the high-brightness layers, gray values, white spot area, TSIF scores, and color shade changes (P<0.05). Conclusion: In-office bleaching combined with resin infiltration can effectively improve the aesthetic effect of dental fluorosis, and the short-term efficacy is stable. The OCT technique can be an alternative method for the diagnosis and efficacy evaluation of dental fluorosis.
