Dental erosion is a multifactorial condition, which is mostly influenced by environmental factors. The aim of this study was to determine the prevalence of dental erosion, its associated risk factors, and their correlation with severity of the condition.
A total of 430 patients who attended the outpatient section of Government Dental College, Thiruvananthapuram, Kerala, India, were selected by systematic sampling method. Erosion was diagnosed by clinical examination and graded using Basic Erosive Wear Examination (BEWE) index. A pretested structured questionnaire on age, gender, medical history, medication history, and food habits was used.
Among the study population, 44% (95% confidence interval, 39.3%-48.7%) had dental erosion. Age above 45 years (79.7%, = 0.000), male population (50%, = 0.032), residents of rural area (49.1%, = 0.000), patients with asthma (84.2%, = 0.000), diabetes (90.9%, = 0.000), gastroesophageal reflux disorder (91.7%, = 0.001), and frequent consumption of orange (68.9%, = 0.000) were identified as factors associated with erosion. The prevalence of dental erosion in the community was high. Results of the study established that better awareness of the condition, better facilities for its early diagnosis in the community, and development of proper preventive strategies are required to reduce the severity of dental erosion.
牙侵蚀是一种多因素疾病，主要受环境因素影响。本研究的目的是确定牙侵蚀的患病率、其相关危险因素以及它们与病情严重程度的相关性。
采用系统抽样方法，选取了印度喀拉拉邦特里凡得琅政府牙科学院门诊的430名患者。通过临床检查诊断侵蚀情况，并使用基本侵蚀性磨损检查（BEWE）指数进行分级。使用一份经过预测试的关于年龄、性别、病史、用药史和饮食习惯的结构化问卷。
在研究人群中，44%（95%置信区间，39.3%-48.7%）患有牙侵蚀。45岁以上的年龄（79.7%，P = 0.000）、男性人群（50%，P = 0.032）、农村地区居民（49.1%，P = 0.000）、哮喘患者（84.2%，P = 0.000）、糖尿病患者（90.9%，P = 0.000）、胃食管反流病患者（91.7%，P = 0.001）以及经常食用橙子（68.9%，P = 0.000）被确定为与侵蚀相关的因素。社区中牙侵蚀的患病率较高。研究结果表明，需要提高对该疾病的认识、改善社区早期诊断的设施以及制定适当的预防策略，以降低牙侵蚀的严重程度。
