Abrasion is the physical wearing of a tooth surface which can involve the presence of a foreign object repeatedly being in contact with the tooth. A 40-year-old male patient reported to our dental clinic with a 2-3 mm uneven gap between his upper and lower front teeth on occlusion. A detailed history revealed that he was a physical education teacher, and the habitual placement of the whistle for the last 15 years caused an indentation on the whistle which coincided with the abraded teeth. Conditions such as abrasion may need active restorations. A general dental practitioner should accurately identify the cause and treat the esthetic and functional impairment as required.
磨损是牙齿表面的物理性磨损，可能涉及异物反复与牙齿接触。一名40岁男性患者前来我们的牙科诊所就诊，其上下前牙咬合时存在2-3毫米的不均匀间隙。详细病史显示，他是一名体育教师，在过去15年里，哨子的习惯性放置导致哨子上出现了一个凹痕，该凹痕与磨损的牙齿相对应。磨损等情况可能需要积极修复。普通牙科医生应准确识别病因，并根据需要治疗美观和功能损害。
