To investigate the relationship between tooth abrasion and long-term chewing betel nut.
The time, frequency, clinical features of occlusal abrasion, and results of pantomography were studied in 64 patients with the habits of chewing betel nut.
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.
Long-term chewing betel nut can result in the abrasion of occlusal surface.
探讨牙齿磨损与长期嚼槟榔之间的关系。
对64例有嚼槟榔习惯的患者的咀嚼时间、频率、咬合磨损的临床特征及曲面体层摄影结果进行研究。
所有患者的咬合面均有不同程度的磨损，从轻度到重度。咀嚼时间越长，咬合磨损越严重（P < 0.01）。随着咀嚼频率的增加，咬合磨损也更严重（P < 0.01）。严重磨损伴有根尖周炎和牙槽骨吸收。
长期嚼槟榔可导致咬合面磨损。
