Method: A prospective, multicentric, epidemiological study was carried out on series of 245 consecutive patients presenting with a chronic facial pain without any obvious cause. A questionnaire (111 questions) was filled by patients and a form (68 questions) by the experimenters after clinical exam. Questionnaire and form were adjusted following 3 calibration meetings and a pilot study (30 cases). Inter- and intra-individual reliability of clinical diagnoses was assessed. A univariate analysis (Chi2) selected 53 variables which discriminated (p<0.001) the diagnostic groups. Three lists of variables were constituted to perform three multifactorial analyses (HOMAL). One list was made of all variables (n=53), a second one with variables not referring to a single tissue or organ (n=27) and a third list was made of variables subjectively selected by the experimenters as being clinically the most important (n=14). Results: The three analyses revealed similar features. Migraines (n=37) strongly clustered. Tension type headache (n=26) was mixed or poorly separated from migraine. Cluster headache (n=11), post-traumatic (n=20) and idiopathic trigeminal neuralgia (n=13) clustered independently in some analyses and in association in others. The idiopathic orofacial pain cases always gathered in a single or in two closely linked groups. Inside this large cluster, stomatodynia (n=42) rose as an homogenous subgroup. On the contrary, atypical odontalgia (n=13), atypical facial pain (n=25) and TMJ and masticatory muscles disorders (n=46) were mixed. Variables obtained from psychological assessment (SCL90) were not added to the 53 somatic variables because another multifactorial analysis showed that they were distributed on a totally different axis. Conclusion: Idiopathic orofacial pain constitutes a separate entity with stomatodynia as the single visible subgroup. This work was supported by Institut UPSA | ||
