摘要
目的分析正畸固定矫治患者牙釉质脱矿的相关危险因素。方法对161例正畸固定矫治患者矫正过程中和矫正结束后进行牙釉质脱矿情况检查和问卷调查。Log-rank Test统计分析患者性别、年龄、口腔卫生维护方法和饮食习惯在牙釉质脱矿发病率的差异;Logistic回归分析导致牙釉质脱矿的危险因素。结果 161例患者的3 619颗牙中有75例患者的328颗牙发生了牙釉质脱矿,其发病率分别为46.6%和9.1%;患者的年龄(P=0.038)、每日刷牙频率(P=0.001)、单次刷牙时间(P<0.000 1)和每周摄入甜食或碳酸饮料频率(P=0.015)在牙釉质脱矿发病率上存在统计学差异;而患者性别、是否使用正畸牙刷、是否使用含氟牙膏、是否使用漱口水在牙釉质脱矿发病率方面无统计学差异;Logistic回归分析证实每日刷牙频率(P=0.005)、单次刷牙时间(P<0.000 1)和每周摄入甜食或碳酸饮料频率(P=0.026)是影响正畸固定矫治患者是否发生牙釉质脱矿的危险因素。结论牙釉质脱矿是正畸固定矫治一个常见的并发症;合理的控制甜食或碳酸饮料摄入、足够的刷牙次数和刷牙时间是防治牙釉质脱矿的重要措施。
Objective To analyze the risk factors of enamel demineralization in orthodontic treatment with fixed appliance. Methods Examination of enamel demineralization and a questionnaire survey were conducted during and after orthodontic treatment with fixed appliance among 161 patients. The correlations between incidence of enamel demineralization and gender, age, methods of maintaining oral hygiene or eating habits were analyzed by Log-rank Test. Logistic regression was used to analyze the risk factors which resulted in enamel demineralization. Results In 3 619 teeth of 161 patients, 328 teeth from 75 patients had enamel demineralization and the inci- dences were 46.6% and 9.1% respectively. The incidence of enamel demineralization was correlated with age （P = 0.038）, daily tooth- brushing frequency （P= 0.001 ）, single toothbrushing time （P〈 0.000 1 ） and weekly intake of sweets or carbonated drinks （P = 0.015）, whereas no significant associations were determined between incidence of enamel demineralization and gender （P = 0.386）, use of orthodontic toothbrush （P = 0.498）, fluoride toothpaste （ P = 0.217） or mouthwash （ P = 0.170）. Logistic regression analysis re- vealed that daily toothbrushing frequency （P = 0.005）, single toothbrushing time （P〈0.000 1 ） together with weekly intake of sweets or carbonated drinks （P= 0.026） were identified as risk factors of enamel demineralization in orthodontic treatment with fixed appliance. Conclusion Enamel demineralization is a frequent complication in orthodontic treatment with fixed appliance. Controlling intake of sweets or carbonated drinks reasonably and sufficient toothbrushing frequency and time are important measures to prevent enamel demi- neralization.
