咀嚼槟榔习惯与牙体磨损关系的临床研究

目的 :探讨长期咀嚼槟榔与牙体磨损的关系。方法 :对长期咀嚼槟榔的 6 4例患者的咀嚼槟榔时间、频率及其牙体牙合面磨损、曲面体层片进行分析。结果 :所有患者后牙牙合面出现不同程度的磨损 ,且咀嚼槟榔时间越长 ,牙合面磨损越严重 (P <0 .0 1) ;咀嚼频率越高 ,牙合面磨损加重 (P <0 .0 1) ,磨损严重者可伴根尖周炎症及牙槽骨不同程度吸收。结论 :长期咀嚼槟榔可导致牙体牙合面不同程度磨损。

Clinical study on the relationship between tooth abrasion and the habits of chewing betel nut

Objective To investigate the relationship between tooth abrasion and long-term chewing betel nut. Methods The time,frequency,clinical features of occlusal abrasion, and results of pantomography were studied in 64 patients with the habits of chewing betel nut. Results The occlusal surfaces of all patients had abrasion from mild to severe .The longer the chewing time,the more severe the occlusal abrasion(P<0.01).The occlusal abrasion became more severe with the increase in chewing frequency (P<0.01).The severe abrasion was accompanied with periapical periodontitis and the resorption of alveolar bone. Conclusion Long-term chewing betel nut can result in the abrasion of occlusal surface.
