Introduction: To investigate the reliability and reproducibility of the individual assessment of midpalatal suture maturation in computed tomography for potential application in Orthodontics and Radiology. Methods: The sample consisted of 202 cone-beam and multi-slice computed tomography (CBCT and MSCT, respectively) scans of patients aged between 11 and 21 years old. Sixty axial slices (n=33 females and 27 males) were randomly selected out of the sample for the individual assessment of midpalatal suture maturation. For the investigation of the reliability and reproducibility of the method, two groups of examiners were established. The first group consisted of 11 orthodontists and the second consisted of 10 radiologists. Each group examined the images twice within an interval of 21 days. During the first and second analyses, the sequence of images was randomized to reduce potential bias. Intraclass correlation coefficient (ICC) was applied to assess the inter- and intra-examiner agreement. Results: The overall interexaminer agreement was satisfactory in the first (ICC: 0.48) and the second (ICC: 0.44) analyses. The intraexaminer agreement outcomes were similar between orthodontists (ICC: 0.49) and radiologists (ICC: 0.52). Conclusion: The method for individual assessment of midpalatal suture maturation revealed potential reliability and reproducibility. However, it depends on the level of training and technical skills for image analysis and interpretation
