摘　　要：目的:调查中老年人牙齿磨耗的程度及其影响因素。方法:以Smith和Knight牙齿磨耗指数TWI分度方法为标准,对牙齿磨耗的88位中老年患者的2214颗患牙进行了口腔检查,并对患者牙齿磨耗原因进行问卷调查。结果:切牙组和尖牙组磨耗的中位数为3,即牙合面牙本质暴露>2mm2,切端牙本质磨损重,牙合面、切缘形态局部或全部丧失:前磨牙组磨耗的中位数为1,即牙合面和切端少量釉质磨损,牙合面或切缘形态轻度损伤;磨牙组磨耗的中位数为2,牙合面釉质磨至牙本质暴露,其范围<2mm2,牙合面形态改变,牙齿高度降低。牙齿磨耗受诸多因素影响,喜食硬质、酸性食物对牙齿磨耗影响最大(P<0.05)。结论:中老年人前牙的磨耗程度高于后牙,牙齿磨耗不仅影响患者正常的咀嚼生理活动,同时也严重影响患者的面容美观。Objective:To investigate the tooth wear and factors affect tooth wear in elderly. Methods:Eighty-eight elderly were examined with the questionnaire of factors cause tooth wear. The Smith & Knight's Tooth Wear Index were used. Results:Both incisor and canine groups showed median scores of 3, which corresponding to extensive wear into the dentine, large dentine area(>2mm2) exposed occlusally/incisally tooth surface, occlusal/incisal morphology totally lost locally or generally, substantial loss of crown height;premolar group showed median score of 1, corresponding to marketed wear facets in the enamel, occlusal/incisal morphology altered; molar group had a median score of 2, which corresponding to wear into the dentine,dentine area(< 2mm2) exposed occlusally tooth surface, occlusall morphology changed in shape with height reduction of the crown. Multiple factors most frequently considered to be contributed to tooth wear, the habituation of eating hard diet or sour diet has significant correlation with tooth wear(P< 0.05). Conclusion:In both arches, anterior teeth of elderly people exhibited greater wear than did posterior teeth. Tooth wear not only affect normal masticatory movement, but also causes esthetic problems for the patients.
