The adolescents were shown a series of photographs of discoloured teeth caused by smoking. Then a mirror was given to the adolescent to let him/her see if similar stains could be seen on his/her teeth. Non-smoking adolescents also received positive feedback for being non-smokers. Duration of a single brief intervention was 2-3 minutes.
