This cross-sectional case-control study evaluated the prevalence of temporomandibular disorder symptoms and bruxism tendency in females diagnosed with endometriosis compared to healthy controls. The researchers assessed participants using clinical examinations and standardized questionnaires to determine the association between these gynecological conditions and oral health issues. Results indicated a significantly higher prevalence of temporomandibular disorders and bruxism among women with endometriosis, suggesting a potential link between the two conditions possibly mediated by inflammatory or hormonal pathways. This paper is centrally about endometriosis — specifically investigating its comorbidity with temporomandibular disorders and bruxism in female patients.

Abstract

Aims: To compare temporomandibular disorder (TMD)-related clinical signs and symptoms, masticatory muscle tenderness, and self-reported bruxism in females with endometriosis and healthy controls with a comparable age distribution.Methods: This cross-sectional case-control study included 28 females aged 24-50 years with a confirmed diagnosis of endometriosis for at least 6 months and 28 healthy controls with a comparable age distribution. All participants underwent a standardized clinical examination of the temporomandibular joint (TMJ) and masticatory muscles. Pain intensity was assessed using the Visual Analog Scale (VAS). Maximum interincisal opening (MIO), TMJ sounds, laterotrusive movements, and mandibular deviation/deflection were also evaluated.Results: No significant differences were observed between the groups regarding MIO, maximum pain-free interincisal opening (MIO2), right and left laterotrusive movements, TMJ sounds, or mandibular deviation and deflection during mouth opening (all p>0.05). However, TMJ pain scores were significantly higher in females with endometriosis than in healthy controls (p
