To determine the prevalence of signs and symptoms in a group of tooth wear patients referred to a hospital-based consultant clinic.
The clinical records of 290 patients referred to the Liverpool University Dental Hospital for tooth wear were reviewed retrospectively. A systematic sampling technique was used to select every alternate patient held on the consultant database.
There were significantly more males than females in a ratio of 2.3:1. Significantly more males (56%) presented with severe tooth wear compared with females (31%) (p <0.001). Aesthetic concerns were the most prevalent presenting complaint (59%) and sensitivity was the second most common presenting complaint (40%). Functional problems and pain were less prevalent at 17% and 14% respectively. Subjects who had lost posterior support had more severe wear and more worn anterior teeth, which was statistically significant (p = 0.001). The proportion of subjects with undiagnosed apical pathology on worn teeth was 13%.
Tooth wear predominated in males in this study. Patient dissatisfaction with appearance is the most common complaint and endodontic signs and symptoms are low in prevalence. Contrary to previous studies, lack of posterior support resulted in greater severity of wear, therefore restoring support is recommended.
确定一组就诊于医院顾问诊所的牙齿磨损患者的体征和症状的患病率。
回顾性分析了 290 名因牙齿磨损而被利物浦大学牙科学院转介的患者的临床记录。采用系统抽样技术，从顾问数据库中选择每一个交替的患者。
男性患者明显多于女性，比例为 2.3:1。与女性（31%）相比，男性（56%）出现严重牙齿磨损的比例显著更高（p <0.001）。美容问题是最常见的主诉（59%），其次是敏感（40%）。功能问题和疼痛分别为 17%和 14%，相对较少见。失去后牙支持的患者牙齿磨损更严重，前牙磨损更多，这具有统计学意义（p = 0.001）。在磨损牙齿上有未诊断的根尖病变的患者比例为 13%。
在这项研究中，男性牙齿磨损更为常见。患者对外观的不满是最常见的抱怨，并且牙髓症状的患病率较低。与以往的研究相反，缺乏后牙支持会导致更严重的磨损，因此建议恢复支持。
