Functional and oral health–related quality-of-life outcomes 12 months after disc repositioning in women with refractory bilateral disc displacement without reduction
Prospective cohort study evaluates quality of life and pain after disc repositioning in women, suggesting significant improvements.
Key Points
This study aims to assess changes in oral health-related quality of life, pain, and mandibular function after disc repositioning in women with refractory disc displacement.
Prospective cohort study involving 34 women with bilateral disc displacement confirmed by diagnostic imaging and clinical criteria.
Outcomes assessed included pain levels, quality of life scores, and mandibular mobility at baseline, 1 month, and 12 months post-surgery.
Data analyzed using repeated-measures ANOVA and linear mixed-effects models.
Pain decreased significantly from 7.6 to 0.7 on the visual analog scale (p < 0.001).
Oral health-related quality of life improved from 29.4 to 7.0 according to the OHIP-14 (p < 0.001).
Mandibular function also improved significantly over the 12 months, with all changes exceeding the minimally clinically important differences.
