The severity of self-reported symptoms at follow-up was also investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>A cone beam CT (CBCT)\/CT follow-up examination [median follow-up 4.1 (1.3\u20136.4) years] was performed in 22 patients with erosive TMJ abnormalities [baseline median age 16 (12\u201318) years]. Imaging characteristics were analyzed and the changes between the examinations were categorized as (A) improvement, (B) no change, or (C) worsening. Severity of follow-up symptoms was evaluated using Jaw Functional Limitation Scale (JFLS-8) and Graded Chronic Pain Scale (Grade 0\u2013IV). Analyses were performed separately for left and right TMJ. Findings at baseline and follow-up were compared using McNemar test to account for dependencies. Changes in proportions of hard tissue findings between examinations were assessed using Wilcoxon signed ranks test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>A significant reduction in the proportion of patients with erosive abnormalities was found [59.1%, 95%\u2009CI (36.4\u201379.3) %]. Baseline erosions improved in 9\/12 (75%) right and 14\/15 (93%) left TMJs. About half repaired; developed an intact cortical outline. Number of joints with osteophytes increased (right: p &lt; 0.04, left: p &lt; 0.003). New osteophytes were mostly found in joints with erosive findings. Low or no limitation of jaw function (Jaw Functional Limitation Scale) was found in 12\/22 (55%) and no or low intensity of pain (Graded Chronic Pain Scale Grade 0 or I) in 19\/22 (86%) at follow-up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>We found a high potential for repair of erosive TMJ abnormalities. However, the patient series was small. The majority of patients assessed their symptom severity at follow-up as low.<\/jats:p><\/jats:sec>","DOI":"10.1259\/dmfr.20190338","type":"journal-article","created":{"date-parts":[[2020,2,26]],"date-time":"2020-02-26T18:28:55Z","timestamp":1582741735000},"page":"20190338","source":"Crossref","is-referenced-by-count":7,"title":["Improvement
