The aim of this study was to determine predictors of erosive tooth wear (ETW) progression, using novel primary-care quantitative analysis techniques.
In a single-centre, prospective, observational cohort longitudinal study, adolescents, aged 11-18 years, underwent a baseline BEWE examination, validated risk factors questionnaire and baseline intraoral scan (IOS, TRIOS 3.0, 3Shape, Copenhagen, Denmark). One year later a repeat scan was taken. Quantitative analysis of wear progression (volume loss) on first permanent molars and upper central incisors was performed using previously published protocols. Multilevel linear regression was used to investigate the associations between baseline predictors and volume loss per mm.
A total of 295 dental surfaces (131 incisors and 164 molars) in 70 patients were analysed for this study. The mean age of participants at baseline was 15.0 years (SD: 0.79), and the average time between scans was 11.8 months (1.61 SD; range 10-13). The mean volume loss per mm of dental surfaces was -0.013 mm (SD: 0.009). Greater volume loss was observed amongst adolescents with higher baseline BEWE scores and those whose parents had lower education as well as on molar than incisor surfaces. No associations were found with dietary acid intake and intrinsic acid exposure when baseline levels of tooth wear, parental education and other factors were controlled for.
The findings help to characterise groups at greater risk of ETW and would indicate that improved screening and upstream preventative measures should form the basis of a preventative program.
Intra-orals scans and registration software might improve the ability to diagnose, monitor and prevent the early loss of dental hard tissue.
本研究旨在使用新型初级保健定量分析技术确定侵蚀性牙齿磨损（ETW）进展的预测因素。
在一项单中心、前瞻性、观察性队列纵向研究中，11-18 岁的青少年接受基线 BEWE 检查、验证的危险因素问卷和基线口内扫描（IOS，TRIOS 3.0，3Shape，哥本哈根，丹麦）。一年后再次进行扫描。使用先前发表的方案对第一恒磨牙和上颌中切牙的磨损进展（体积损失）进行定量分析。使用多水平线性回归分析来研究基线预测因素与每毫米体积损失之间的关系。
共有 70 名患者的 295 个牙面（131 个切牙和 164 个磨牙）参与了本研究。参与者的基线平均年龄为 15.0 岁（SD：0.79），两次扫描之间的平均时间为 11.8 个月（1.61 SD；范围 10-13）。牙面的平均体积损失为-0.013 mm（SD：0.009）。基线 BEWE 评分较高、父母受教育程度较低以及磨牙牙面的青少年磨损程度较高，体积损失较大。在控制了基线牙磨损、父母教育程度和其他因素后，饮食酸摄入和内在酸暴露与体积损失无相关性。
这些发现有助于确定 ETW 风险较高的人群，并表明应改善筛查和上游预防措施，为预防计划提供基础。
口腔内扫描和注册软件可能会提高诊断、监测和预防早期牙体硬组织丧失的能力。
