Erosive tooth wear (ETW) is defined as the irreversible chemo-mechanical loss of dental hard tissues without plaque or bacteria and has been a growing phenomenon in the general population worldwide. The aim of this study was to determine the prevalence of ETW and the associated risk factors among young military personnel in Singapore.
This cross-sectional study consisted of a questionnaire and clinical examination of military personnel between 18 and 25 years. The questionnaire collected information on demographics, medical and dental history, lifestyle and dietary habits. Tooth wear was clinically evaluated using the Basic Erosive Wear Examination (BEWE) index. The participants were profiled into four risk categories (none, low, moderate, severe) based on the sum score. Multivariable logistic regression analysis was performed to determine the risk factors associated with the presence of ETW.
Out of 1296 participants evaluated, 21.8% of them had ETW. The anterior sextants were more affected by erosion than posterior sextants for both arches. The risk factors significantly associated with ETW were GERD (OR = 2.83, p = 0.041), presence of self-reported TMD symptoms (OR = 2.51, p < 0.001), acidic food (OR = 2.03, p < 0.001) and drinks (OR = 3.07, p < 0.001), high caries risk (OR = 4.59, p < 0.001) and toothbrush stiffness (OR = 4.67, p < 0.001).
ETW is prevalent among the young military population, with over half of the population at a risk of ETW. Gastric reflux disease, TMD, acidic diet, dental caries susceptibility and the use of stiff toothbrushes were identified as significant risk factors.
A large proportion of young military personnel exhibited mild to moderate risk of ETW. Dental professionals can identify risk-susceptible individuals at a young age and educated them with preventive measures and dietary interventions to prevent the progression of the condition.
侵蚀性牙磨损（ETW）被定义为无菌斑或细菌的牙体硬组织不可逆的化学-机械损失，在全球范围内已成为一种普遍现象。本研究旨在确定新加坡年轻军人中 ETW 的流行情况及其相关危险因素。
这是一项横断面研究，对 18 至 25 岁的军人进行问卷调查和临床检查。问卷收集人口统计学、医疗和牙科史、生活方式和饮食习惯等信息。使用基本侵蚀性磨损检查（BEWE）指数对牙齿磨损进行临床评估。根据总分，将参与者分为四个风险类别（无、低、中、高）。采用多变量逻辑回归分析确定与 ETW 存在相关的危险因素。
在评估的 1296 名参与者中，有 21.8%的人患有 ETW。在前磨牙区，无论上颌或下颌，前磨牙均比磨牙更易受到侵蚀。与 ETW 显著相关的危险因素是胃食管反流病（GERD）（OR=2.83，p=0.041）、自述存在颞下颌关节紊乱病（TMD）症状（OR=2.51，p<0.001）、食用酸性食物（OR=2.03，p<0.001）和饮料（OR=3.07，p<0.001）、高龋病风险（OR=4.59，p<0.001）和使用硬毛牙刷（OR=4.67，p<0.001）。
侵蚀性牙磨损在年轻军人中较为普遍，超过一半的人群存在 ETW 风险。胃食管反流病、TMD、酸性饮食、龋齿易感性和使用硬毛牙刷被确定为显著的危险因素。
很大一部分年轻军人有轻度至中度 ETW 风险。牙医可以在年轻时识别出易患风险的个体，并通过预防措施和饮食干预对其进行教育，以防止病情进展。
