Non-carious cervical lesions (NCCLs) are often encountered in clinical practice and their aetiology attributed to toothbrush abrasion, erosion and tooth flexure. This paper aims to determine the prevalence and severity of NCCLs in a sample of patients attending a university clinic in Trinidad and to investigate the relationship with medical and dental histories, oral hygiene practices, dietary habits and occlusion. Data were collected via a questionnaire and clinical examination. Odds ratios were used to determine the association of the presence of lesions and the factors examined. One hundred and fifty-six patients with a mean age of 40.6 years were examined of whom 62.2% had one or more NCCLs. Forty five per cent of the lesions were sensitive to compressed air. Younger age groups had a significantly lower correlation with the presence of NCCLs than older age groups. Other significant factors included patients who reported heartburn, gastric reflux, headaches, bruxism, sensitive teeth and swimming or had a history of broken restorations in the last year. There was also significant correlation of NCCLs in patients who brushed more than once a day or used a medium or hard toothbrush. Patients with vegetarian diets and those who reported consuming citrus fruits, soft drinks, alcohol, yoghurt and vitamin C drinks were associated with the presence of lesions. Significant associations were also found in patients with group function, faceting, clicking joints or those who wore occlusal splints.
非龋性颈部病变（NCCLs）在临床实践中经常遇到，其病因归因于牙刷磨损、侵蚀和牙齿弯曲。本文旨在确定特立尼达一家大学诊所患者样本中NCCLs的患病率和严重程度，并调查其与医学和牙科病史、口腔卫生习惯、饮食习惯和咬合的关系。通过问卷调查和临床检查收集数据。使用优势比来确定病变的存在与所检查因素之间的关联。对156名平均年龄为40.6岁的患者进行了检查，其中62.2%有一个或多个NCCLs。45%的病变对压缩空气敏感。较年轻年龄组与NCCLs存在的相关性明显低于较年长年龄组。其他显著因素包括报告有烧心、胃反流、头痛、磨牙症、牙齿敏感和游泳的患者，或在过去一年中有修复体破损史的患者。每天刷牙超过一次或使用中硬牙刷的患者中NCCLs也有显著相关性。素食患者以及报告食用柑橘类水果、软饮料、酒精、酸奶和维生素C饮料的患者与病变的存在有关。在具有组牙功能、小面、关节弹响的患者或佩戴咬合板的患者中也发现了显著关联。
