The aim of this study was to investigate oral changes in subjects who have assumed a vegan diet (a diet completely lacking in meat and foods of animal origin) for a long time. The study included 15 subjects, aged 24 to 60 year, who had been following a vegan diet for a minimum of 18 months to a maximum of 20 years, and 15 age- and sex-matched control subjects who consumed food of animal origin.
The study revealed that those eating meat and foods of animal origin had a lower incidence of demineralization and white spots on their teeth compared to vegans.
