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.
