目的：量化的患病率白色斑点病变（WSL）的前牙，其次，评估危险因素和predictors.Materials和方法：数字照片和记录的885例随机选择的患者进行了评价治疗前后。图表信息包括性别、年龄以及条带和解除条带日期。治疗前后对氟中毒和口腔卫生进行评价。记录并比较所有12颗前牙的治疗前和治疗后WSL。计算风险比（RR）和绝对风险（AR），以确定WSL formation.Results的可能性和风险：总体而言，23.4%的患者在治疗过程中至少发生一次WSL。上颌前牙受累较下颌多。上颌尖牙和下颌尖牙是最敏感的。性别间WSL无显著差异。氟中毒、治疗时间超过36个月、治疗前卫生状况差、治疗期间的卫生变化以及先前存在的WSL都与WSL的发生显著相关（P <0.05）。发展WSL的最高风险与预先存在的WSL（RR = 3.40），其次是在治疗期间口腔卫生下降（RR = 3.12）和治疗前口腔卫生不良（RR = 2.83）。结论：近25%的患者发展WSL，而在治疗中，取决于氟中毒，治疗时间，预先存在的WSL，和口腔卫生。正畸医生在做出治疗决定时需要注意这些风险因素。
Purpose: To quantify the prevalence of white spot lesions (WSLs) on the anterior teeth and, secondarily, to evaluate risk factors and predictors.Materials and Methods: Digital photographs and records of 885 randomly chosen patients were evaluated before and after treatment. Chart information included gender, age, as well as banding and debanding dates. Fluorosis and oral hygiene before and after treatment were also evaluated. Preexisting and posttreatment WSLs were recorded and compared for all 12 anterior teeth. Risk ratios (RR) and absolute risk (AR) were calculated to determine the likelihood and risk of WSL formation.Results: Overall, 23.4% of the patients developed at least one WSL during their course of treatment. Maxillary anterior teeth were affected more than mandibular teeth. The maxillary laterals and canines and the mandibular canines were the most susceptible. There was no significant difference in WSLs between genders. Fluorosis, treatment time in excess of 36 months, poor pretreatment hygiene, hygiene changes during treatment, and preexisting WSLs were all significantly (P < .05) related to the development of WSLs. The highest risk of developing WSLs was associated with preexisting WSLs (RR = 3.40), followed by declines in oral hygiene during treatment (RR = 3.12) and poor pretreatment oral hygiene (RR = 2.83).Conclusions: Nearly 25% of the patients developed WSLs while in treatment, depending on fluorosis, treatment time, preexisting WSLs, and oral hygiene. Orthodontists need to be mindful of these risk factors when making treatment decisions.
