Abstract |
INTRODUCTION: The precision of cranial and maxillofacial linear and angular measurements is of great importance in the dental field owing to their major role in treatment planning and follow up. Over the last decade, the use of Cone Beam Computed Tomography (CBCT) has tremendously escalated to overcome the drawbacks of 2D imaging techniques. Accordingly, it has been the focus of many studies to assess the accuracy of this radiographic technique in obtaining linear and angular skull measurements. OBJECTIVES: The aim of this study was to determine the reliability of linear and angular measurements obtained from CBCT in comparison to direct skull measurements. MATERIALS AND METHODS: This study was conducted on 12 dry human skulls. Ten linear and two angular measurements were obtained between identified landmarks on each skull. The skulls were subjected to CBCT examination. The linear and angular measurements obtained from CBCT were compared to the gold standard. RESULTS: The results of the current study showed very good intra-observer and inter-observer reliability regarding all the assessed linear and angular measurements obtained from gold standard and CBCT scans. Regarding linear measurements, all measurements obtained from CBCT showed underestimated values compared to the gold standard except for the nasal height. Regarding angular measurements, CBCT showed non-significant underestimated values in relation to gold standard. CONCLUSION: Linear and angular measurements obtained from CBCT are accurate and reliable and can be confidently used for different maxillofacial clinical applications especially in orthodontics. |
