Abstract:OBJECTIVE: The aim of this article was to study the causes of vertical root fractures. METHODS: Age and gender, personal history of the sickness and clinical features of vertical root fracture in 27 patients were studied. RESULTS: Vertical root fracture tended to occur in patients with a higher mean age (54 years) and were more frequent in male (70%) than in female. Mesial or mesial-buccal roots of the first molars (78%) were the predilection site of vertical root fracture. All of the patients had chewed betel nut for 10 to 25 years. The occlusal surfaces were abrasive. CONCLUSION: Vertical root fracture is associated with an excessive, repetitive, and heavy masticatory stress applied to a tooth.
