Bruxism and Severity of Temporomandibular Dsyfunction

The Effect of Bruxism on Masticatory Functionality and Severity of Temporomandibular Dsyfunction: A Cross-sectional Study

The aim of the study was to investigate the effect of bruxism on Temporomanbular joint functionality and dysfunction severity in individuals with Temporomandibular Dysfunction (TMD).

The study included 91 individuals aged 20-55 years with TMD. Participants who volunteered to participate in the study signed the Informed Consent Form and completed the Descriptive Data Form including demographic characteristics. The presence of bruxism in individuals with TMD was questioned and the maximum mouth opening measurement was recorded. TMD severity was assessed by Fonseca's Anamnestic Questionnaire (FAQ), pain severity was assessed by Numeric Pain Scale (NPS), and masticatory and TMJ functioning was assessed by JAW Functional Limitation Scale-20 (JFLS-20). The evaluations of the participants were performed only once.

Inclusion Criteria:

• Aged between 20 and 55 years,
• Diagnosed with TMD,
• volunteer to participate in the study

Exclusion Criteria:

• having a non-reduced disc problem,
• surgical operation due to spine, abdomen and/or TMJ problem,
