title: Can one predict the likely specific orofacial pain syndrome from a self-completed questionnaire?
abstract: To estimate the prevalence of orofacial pain (OFP) by specific diagnostic subgroups in the general population. Cross-sectional population study. General medical practice in South East Cheshire, UK. Participants of baseline investigation who completed the full postal questionnaire (1510, adjusted study participation rate 81%). Clinical examination was attended by 126 (43%) of all the participants who reported OFP in the questionnaire. These individuals were classified as musculoligamentous/soft tissue type, dentoalveolar or neurological/vascular. OFP duration, location, descriptors and statements on OFP were predictors of classification group. The estimated prevalence in the general population of musculoligamentous/soft tissue type of OFP was 7%, dentoalveolar 7% and neurological/vascular 6%. This study has derived a statistical model to classify participants with OFP into three broad groups (musculoligamentous/soft tissue, dentoalveolar and neurological/vascular) based on questionnaire information about OFP (OFP chronicity, location and verbal descriptors of pain). It is potentially useful in large population studies of OFP, where a clinical examination is not possible, however, further validation of its performance in large populations are necessary.
