pH changes in plaque after eating snacks and meals, and their modification by chewing sugared- or sugar-free gum

摘要: Previous studies have suggested that if either sugar-free or sucrose-containing chewing gum is chewed after acidogenic meals snacks, the plaque pH response to latter reduced and potential for remineralisation of experimental white spot caries lesions enhanced. This study has compared effects both gums on (measured by sampling technique) in 10 subjects who standard challenges (sucrose rinse, cupcake, fried chicken dinner). The results showed while can significantly reduce acid response, appears more effective.
