摘　　要：目的:了解体检人群中中老年人群楔形缺损罹患情况和发生的相关因素,为其预防保健提供临床参考依据。方法:对北京地区40～89岁2038例中老年健康体检人群检查楔形缺损罹患情况,计算不同牙位、不同年龄组别的患病率。并对楔形缺损发生相关因素进行问卷调查。结果:楔形缺损总患病率为48.62%,各年龄组患牙率总体上随年龄的增长而上升。第一前磨牙楔形缺损的发生率最高,第二磨牙楔形缺损发生率最低。上颌牙齿楔形缺损发生率高于下颌牙齿。影响楔形缺损发生的因素中以不合理刷牙方式比例最高。结论:楔形缺损与牙位和年龄有明显关系,病人中刷牙方式不合理者比例高。AIM：To investigate the incidence rate of wedge-shaped defects in elderly people by oral health examination and to set clinical reference for the prevention of this disease. METHODS：An oral health survey of 2038 people with age ranging from 40 to 89 was conducted in Beijing. The occurrence of wedge-shaped defects in different teeth and different age groups was calculated. The correlative factors of wedge-shaped defects were explored by questionnaire survey. RESULTS：The overall incidence rate of wedge-shaped defects was 48. 62% and the rate increased with age. The incidence of premolar wedge-shaped defects was the highest,while the incidence rate of second-molar wedge-shaped defects was the lowest. The incidence of wedge-shaped defects in maxilla teeth was higher than in mandible teeth. Incorrect tooth-brushing was the most prominent in all correlative factors. CONCLUSION：The incidence of wedge-shaped defect is related to tooth location,age,and the ratio of incorrect brushing. Regular oral health check-up is helpful to the early detection of wedge-shaped defects,and good oral hygiene habits are good methods to prevent wedge-shaped defects.
