The present study appraises the construct and concurrent validity of the Visible Occlusal Plaque Index (VOPI) as a measure of the association between dental biofilm and caries occurrence and activity in permanent molars. A total of 618 10–15 year old Brazilian adolescents were included in the study. Data on adolescents’ socio-demographic and oral health determinants were collected. The occurrence and distribution of occlusal plaque on first and second permanent molars were mapped and recorded at individual surface-anatomical sites of the groove-fossa-system. [...]
