BackgroundTo determine the impact of self-perceived halitosis on social interactions, and the effect of using an oral rinse for management of halitosis.MethodsA survey among a representative sample of the Dutch population (n = 1082), and a pre-post study among a sample of consecutive coming-by volunteers (n = 292).ResultsParticipants of the representative sample rated their oral odor as 66.8 ± 17.2 and the consecutive volunteers as 70.9 ± 16.7 (range: 0-100). Sizable proportions (15.3 % and 38.1 %, respectively) indicated to always take into account their (bad) oral odor when meeting a person for the first time. The worse people perceived their oral odor, the more likely they were to take into account to keep a certain distance. Following the use of the oral rinse, a significant decline was found of the extent to which the participants reported to take into account their oral odor when meeting a person for the first time. Both studies identified a subgroup of individuals (9.1 % and 28.1 % respectively) who reported to keep a certain distance when meeting other people, despite a "fresh" self-perceived oral odor.ConclusionThe results suggest that self-perceived oral odor negatively affects social interactions, and that adequate management of halitosis has the potential to improve such interactions.
