At present it is considered as irreversible and incurable. Aims: Assessment of risk factors and the role of habit variables such as duration and frequency in the severity of OSMF and to ascertain the association of gender predilection for different habits and severity of OSMF. Material and Methods: Patient personal history was recorded with chewing habits, including frequency and duration of chewing. This descriptive retrospective study of 179 OSMF patients was carried out at the tertiary level hospital in the central India. The clinico-demographic data including details of habits was collected.
