The aim of this study was to observe the prevalence of diagnostic groups of temporomandibular disorders (TMD) in patients who were referred or sought treatment for TMD and/or orofacial pain in a private clinic. The clinical records of 357 patients were evaluated and selected based on inclusion/exclusion criteria; the mean age was 32 years. A clinical examination was performed and the diagnosis was based on the American Academy of Orofacial Pain criteria. Results showed that 86.8% of patients were women and 93.3% of the patients presented more than one diagnosis. The most frequent chief complaint (n=216, χ2= 30.68, p=0.001) and total diagnosis realized (n= 748, χ2=14.14, p=0.001) were muscle related. We concluded that women seek treatment for dysfunction/disorders of orofacial structures more than men do; patients seeking specialized treatment have more than one diagnosis and muscle dysfunction is more prevalent than intra-articular disorders.
