This is a cross sectional study to determine the attitudes and practices in smoking cessation counselling among dentists in Kelantan and to identify the barriers that prevent them from doing so. Self-administered questionnaires were distributed to 152 dentists practising in Kelantan. A total of 84 (55.2%) questionnaires were completed and returned. Although majority of the dentists (98.8%) agreed that they have a role in smoking cessation counselling, only few of them (17.9%) were actually involved in a considerable extent. The main barriers cited were lack of training and time in their practice. In conclusion, dentists in Kelantan believed that they have a role in smoking cessation counselling but their involvement was rather limited.
