Resumoabstract – A study of habitual self mutilation of the buccal and/or labial mucosa by biting was conducted on 8,589 persons attending the Royal Dental College, Copenhagen. Forty‐two cases were found. The youngest patient was 5 years old and the oldest was 47. The condition occurred most frequently (1.77%) among persons aged 15–19 years. There was no difference in prevalence between males and females. Combined mutilation of cheek(s) and lip(s) was more frequent (62%) than isolated mutilation of the cheek(s) (24%) or isolated mutilation of the lip(s) (14%). Bilateral biting of the cheeks was more frequent than unilateral biting, and biting of the lower lip was more frequent than biting of the upper lip. Ninety‐three per cent of the patients were aware of their habit, and most of them stated that they had been biting for years. Twenty patients were re‐examined; in all but one patients the biting persisted but in 7 patients the location of the lesions had changed. In several cases a link could be traced to personal problems and mental stress. It was further noticed that many patients were students and white‐collar workers, suggesting that “intellectual” work may predispose for the habit.
