Objective: To determine self-reported bruxism experience among the undergraduates of a Nigerian university, other associated parafunctional habits and oral health problems. Materials and Methods: This cross-sectional study was conducted on undergraduates dwelling in University of Benin, main campus hostel located in Ugbowo, Benin City, Nigeria. The 640 participants that met the inclusion were randomly recruited from four hostels (two males and two females) during the weekend. A self-developed validated questionnaire was the data collection tool. Results: Out of the 578 (response rate = 93.2%) study participants, aged between 15 and 48 years with a mean age of 23.6 ± 8.5, 143 reported bruxism, giving 24.7% prevalence. This was significantly associated with gender. The reported patterns of bruxism were awake (48.3%), nocturnal (15.4%), and diurnal (36.4%). The prevalence of nail biting and anxiety/stress was 56.6% and 29.9%, respectively. These were significantly higher in bruxists than nonbruxists. More of the participants, who reported chewing/biting biro as well as tobacco and alcohol consumption, also reported bruxism. Oral health problems reported include tooth mobility (9.5%), shocking sensation (40.3%), chewing difficulty (6.7%), temporomandibular joint noise/or pain (5.4%), and jaw injury (7.6%). These conditions were significantly more common among those who reported bruxism. Conclusion: Data from this study revealed that one out of every four studied participants is a bruxist. There is need for the dentists to suspect bruxism in undergraduates presenting with oral health problems such as shocking sensation, tooth mobility, nail biting, chewing difficulty, anxiety/stress, jaw injury, joint noise and pain on mouth opening/closing, to give a holistic care.
