Med Oral Patol Oral Cir Bucal. 2017 Nov 1;22(6):e669-e6781698-6946http://hdl.handle.net/10668/19365Background: To analyze the association between the OHIP-14 and the different subtypes making up the clinical and psychological axis obtained using the RDC/TMD.Material and Methods: 407 patients treated at the TMD unit of the Andalusian Healthcare Service were administered the Spanish version of the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire (RDC/TMD), together with the Oral Health Impact Profile questionnaire (OHIP-14). The degree of association between the patients' score in the OHIP-14 and the clinical and biopsychosocial variables was analyzed through bivariate and multivariate analyses, specifically through linear regression.Results: 89.4% of the treated patients were women, while 10.6% were men, with an average age of 42.08 +/- 14.9 years. The mean score and standard deviation for the OHIP-14 was 20.57 +/- 10.73. A significant association (p< 0.05) was observed with the following variables: Axis I, jaw disability checklist, depression, somatization, perceived pain duration, and pain interference with activities of daily living. Conclusions: The analysis of the relation between self-perceived health in patients with TMD, as measured by the OHIP-14, showed a R2 of 0.3979, with a higher Beta value for the association between the OHIP and patients with both myofascial pain and arthopathy, jaw disability, depression, a higher pain duration and a higher pain interference with activities of daily living.enTemporomandibular disordersPsychological factorsOral health impact profilePublic healthcareResearch diagnostic criteria for temporomandibular disorders (RDC/TMD)Impact profileOrofacial painDiagnostic-criteriaValidationQuestionnaireReliabilityValidityAdultsresearch articleopen accessPerfil de impacto de enfermedadAdultoDolor facialEncuestas y cuestionarios10.4317/medoral.21746https://doi.org/10.4317/medoral.21746423521300002
