To assess the interplay between dietary acid intake, toothbrushing and erosive tooth wear as aetiological factors in self-reported DH MATERIALS AND METHODS: This is a secondary analysis on previously collected data from 600 participants with (n=300) and without (n=300) severe erosive tooth wear. Participants recruited from restorative clinics of King's College London Dental Institute (REC Ref 14/EM/1171) were questioned on their self-reported DH, frequency and timing of dietary acid intake, habits associated with consumption of dietary acids and tooth brushing habits. Erosive tooth wear was assessed using Basic Erosive Wear Examination (BEWE). Differences in diet and brushing habits between those with self-reported DH and those without were analysed using descriptives and logistic regression in SPSS vers. 24.
Of those reporting with DH (n=272), a greater number spent ≥10min eating fruit per sitting, (n=46) and had a drinking habit such as sipping, swishing or holding drinks in the mouth (n=72) compared to those without DH (n=26 OR 2.72, 95%CI [1.32-5.61], p=0.007 and n=38 OR2.33, 95%CI [1.40-3.88], p=0.001, respectively). More DH participants used a soft toothbrush (n=36) compared to those without DH (n=18 OR 2.35, 95%CI [1.20-4.59], p=0.013). No association was observed with frequency of daily toothbrushing or dietary acid intake.
Contact time between the tooth and the acid may be a more important risk factor for DH compared to frequency of dietary acid intake or frequency of toothbrushing. Other possible aetiological factors should be considered. CLINICALTRIALS.
NCT02449434 CLINICAL SIGNIFICANCE: Increased contact time with dietary acids and sipping swishing or holding drinks in the mouth prior to swallowing should be addressed as an aetiological factor in DH. Toothpaste abrasivity and toothbrush filament stiffness may play a greater role in DH compared to frequency of toothbrushing.
评估饮食酸摄入、刷牙和侵蚀性牙齿磨损之间的相互作用，作为自我报告的酸蚀症的病因因素。
这是对来自伦敦国王学院牙科研究所修复诊所招募的 600 名参与者（n=300）和无严重侵蚀性牙齿磨损参与者（n=300）的先前收集数据的二次分析。参与者被问到他们自我报告的酸蚀症、饮食酸摄入的频率和时间、与饮食酸消耗相关的习惯以及刷牙习惯。使用基本侵蚀性磨损检查（BEWE）评估侵蚀性牙齿磨损。使用 SPSS vers.24 中的描述性分析和逻辑回归分析比较自我报告有酸蚀症和无酸蚀症参与者之间的饮食和刷牙习惯差异。
在报告有酸蚀症的参与者中（n=272），与无酸蚀症的参与者相比，有更多的人每次坐着吃水果的时间超过 10 分钟（n=46），并且有饮用习惯，如小口喝、漱口或在口中含饮料（n=72）。报告有酸蚀症的参与者中，使用软毛牙刷的人（n=36）多于无酸蚀症的参与者（n=18）（OR 2.35，95%CI [1.20-4.59]，p=0.013）。没有观察到每日刷牙频率或饮食酸摄入与酸蚀症之间存在关联。
与饮食酸摄入频率或每日刷牙频率相比，牙齿与酸接触的时间可能是酸蚀症的一个更重要的危险因素。应考虑其他可能的病因因素。
临床试验。
NCT02449434
在吞咽前增加与饮食酸的接触时间以及小口喝、漱口或在口中含饮料，应作为酸蚀症的病因因素加以解决。与每日刷牙频率相比，牙膏的磨损性和牙刷刷毛的硬度可能在酸蚀症中发挥更大的作用。
