[Self-perceived Oral Odour and Social Interaction]

This study examined the influence of self-perceived oral odour on social interaction. A representative sample of 1,082 people from the Dutch population of 16 years and older, were surveyed. On average, the participants graded their oral odour as 66.8 on a scale 0-100; 4.2% judged their oral odour as 'not fresh' (score < or = 30). Approximately 65% indicated that they took into account the fact that, when meeting somebody for the first time, that person might smell their oral odour. Participants judging their oral odour to be not fresh were shown to keep significantly more distance when meeting somebody than participants judging their oral odour as fresh. Noteworthy was a subgroup of participants who judged their oral odour as fresh, but indicated that they always kept a certain distance to other people. The results suggest that self-perceived oral odour is a potential barrier in social interaction.
