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.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
