Abstract

Introduction: The purpose of this study was to determine if MRI can be used to accurately measure tooth lengths. Methods: MRI tooth length measurements were compared with “actual tooth lengths” as measured on CBCT scans. Twenty three subjects received two scans (one CBCT and one MRI). Tooth length was measured and compared between the resultant images. Intraclass correlations were used for statistical analysis. Results: Tooth length measurements made on MRI scans showed moderate to almost perfect agreement with tooth length measurements made on CBCT scans. Higher levels of agreement were present in the maxillary arch compared to the mandibular arch. Conclusion: MRI tooth length measurements are similar to CBCT tooth length measurements.
