Which of the following is NOT a recognized effect of chronic betel/areca nut chewing?
Show answer and explanation
Correct answer: A. Xerostomia (betel nut is actually a sialogogue and tends to stimulate salivation, not dry the mouth)
Betel/areca nut chewing classically causes extrinsic staining, gingival recession/irritation, and — most seriously — oral submucous fibrosis (a premalignant condition). It does not typically cause xerostomia; if anything, chewing stimulates salivary flow, making xerostomia the 'odd one out' here.
