      Angenete, Oskar W; Augdal, Thomas Angell; Shi, Xie-Qi; Säll, Mats; Fischer, Johannes Maria; Nordal, Ellen Berit; Rosendahl, Karen (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-10)
      Background The temporomandibular joint (TMJ) is frequently involved in juvenile idiopathic arthritis (JIA). Diag‑ nostic imaging is necessary to correctly diagnose and evaluate TMJ involvement, however, hitherto little has been published on the accuracy of the applied scoring systems and measurements. The present study aims to investigate the precision of 20 imaging features and fve measurements ...
    • Effects of motion correction, sampling rate and parametric modelling in dynamic contrast enhanced MRI of the temporomandibular joint in children affected with juvenile idiopathic arthritis 

      Starck, Lea; Andersen, Erling; Macíček, Ondřej; Angenete, Oskar W; Augdal, Thomas Angell; Rosendahl, Karen; Jirík, Radovan; Grüner, Renate (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-13)
      The temporomandibular joint (TMJ) is typically involved in 45–87% of children with Juvenile Idiopathic Arthritis (JIA). Accurate diagnosis of JIA is difficult as various clinical tests, including MRI, disagree. The purpose of this study is to optimize the methodological aspects of Dynamic Contrast Enhanced (DCE) MRI of the TMJ in children. In this cross-sectional study, including data from 73 JIA ...
    • In children and adolescents with temporomandibular disorder assembled with juvenile idiopathic arthritis ‑ no association were found between pain and TMJ deformities using CBCT 

      Fischer, Johannes Maria; Augdal, Thomas Angell; Angenete, Oskar W; Gil, Elisabeth Grut; Skeie, Marit Slåttelid; Åstrøm, Anne-Kristine N; Tylleskär, Karin; Rosendahl, Karen; Shi, Xie-Qi (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-12)
      Background - Children and adolescents with juvenile idiopathic arthritis (JIA) may suffer from temporomandibular disorder (TMD). Due to this, imaging diagnosis is crucial in JIA with non-symptomatic TM joint (TMJ) involvement. The aim of the study was to examine the association between clinical TMD signs/symptoms and cone-beam computed tomography (CBCT) findings of TMJ structural deformities in ...
    • MRI in the Assessment of TMJ-Arthritis in Children with JIA; Repeatability of a Newly Devised Scoring System 

      Angenete, Oskar W; Augdal, Thomas Angell; Rygg, Marite; Rosendahl, Karen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-19)
      Rationale and Objectives: The temporomandibular joint (TMJ) is commonly involved in children with juvenile idiopathic arthritis. The diagnosis and evaluation of the disease progression is dependent on medical imaging. The precision of this imaging is under debate. SeveralR scoring systems have been proposed but transparent testing of the precision of the constituents of the scoring systems is ...
    • Normal magnetic resonance appearances of the temporomandibular joints in children and young adults aged 2–18 years 

      Angenete, Oskar W; Augdal, Thomas Angell; Jellestad, Stig; Rygg, Marite; Rosendahl, Karen (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-12)
      <p><i>Background</i>: Knowledge of normal appearances of the temporomandibular joint (TMJ) is paramount when assessing the joint for disease in juvenile idiopathic arthritis. Reliable features defining normal TMJs in children are limited.</p> <p><i>Objective</i>: To establish reliable normal standards for the TMJ at magnetic resonance imaging (MRI).</p> <p><i>Materials and methods</i>: We ...
    • Observer agreement of imaging measurements used for evaluation of dentofacial deformity in juvenile idiopathic arthritis 

      Fischer, Johannes Maria; Halbig, Josefine Mareile; Augdal, Thomas Angell; Angenete, Oskar W; Stoustrup, Peter; Kristensen, Kasper Dahl; Skeie, Marit Slåttelid; Tylleskär, Karin; Rosén, Annika; Shi, Xie-Qi; Rosendahl, Karen (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-02)
      Objectives: To examine the precision of imaging measures commonly used to assess mandibular morphology in children and adolescents with juvenile idiopathic arthritis (JIA). Secondly, to compare cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) in the measurement of condylar height.<p> <p>Methods: Those included were children diagnosed with JIA during 2015–18 who had had ...
    • Revisiting the radiographic assessment of osteoporosis-Osteopenia in children 0-2 years of age. A systematic review 

      Rosendahl, Karen; Lundestad, Anette; Bjørlykke, John Asle; Lein, Regina Küfner; Angenete, Oskar W; Augdal, Thomas Angell; Müller, Lil-Sofie Ording; Jaramillo, Diego (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-02)
      <i>Background</i> - Imaging for osteoporosis has two major aims, first, to identify the presence of low bone mass (osteopenia), and second, to quantify bone mass using semiquantitative (conventional radiography) or quantitative (densitometry) methods. In young children, densitometry is hampered by the lack of reference values, and high-quality radiographs still play a role although the evaluation ...
    • Vitamin D, oral health, and disease characteristics in juvenile idiopathic arthritis: a multicenter cross-sectional study 

      Cetrelli, Lena Elisabet; Bletsa, Athanasia; Lundestad, Anette; Gil, Elisabeth Grut; Fischer, Johannes Maria; Halbig, Josefine Mareile; Frid, Paula Hanna Therese; Angenete, Oskar W; Lien, Ingrid Lillevoll; Rosén, Annika; Tylleskär, Karin; Luukko, Keijo; Nordal, Ellen Berit; Åstrøm, Anne-Kristine N; Skeie, Marit Slåttelid; Feuerherm, Astrid Jullumstrø; Sen, Abhijit; Rygg, Marite (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-08)
      Background: Vitamin D defciency has been associated with autoimmune diseases and oral health. Knowledge about the association between vitamin D status and oral conditions in JIA is limited. We aimed to investigate vitamin D status in a cohort of Norwegian children and adolescents with JIA and possible associations between serum vitamin D levels, clinical indicators of oral health, and JIA disease ...
