OBJECTIVES: There is dearth of study reporting overall prevalence of psychogenic orofacial pain in our environment, and many aspects of such disorder are relatively unknown. The goal of this study was to show the overall prevalence of psychogenic orofacial pain and to determine the age and gender distribution of the various types of psychogenic orofacial pain in a Nigerian population.
PATIENTS AND METHODS: This was a retrospective study conducted on patients suffering from psychogenic orofacial pain who were referred to the Department of Oral Pathology and Medicine, University of Benin Teaching Hospital, over a period of 4 years. The differential diagnosis was made on the basis of history, clinical examination, laboratory and radiographic investigations and by applying the criteria laid down by International Association for the Diagnosis of Pain.
RESULTS: Out of a total of 1,019 patients seen during the study period, 57 (5.6%) cases of psychogenic orofacial pain were diagnosed. The males accounted for 36.8% (n=21), while the females accounted for 63.2% (n= 36) giving a ratio of 1:1.7. Majority of the patients were in the age group of 41 to 50 years. Analysis showed the patients were suffering from temporomandibular pain dysfunction syndrome (TMDS) 38 (66.7%), burning mouth syndrome (BMS) 9 (15.8%), atypical facial pain 6 (10.8%) and, atypical odontalgia 4 (7.0%)
CONCLUSION: The overall prevalence of psychogenic orofacial pain was 5.6% in the population studied. TMDS was the most common type, followed by BMS and they occurred mostly in young adult female patients.
