Correlation between Mesio-Distal Angulation and Bucco.-Lingual Inclination of First and Second Maxillary Premolars Evaluated with Panoramic Radiography and Cone-Beam Computed Tomography

Background: Panoramic radiography creates distortion in teeth position and inclination especially lateral areas of the arches due to acquisition curved shape dental arch. The aim this study was evaluate panoramic compared cone-beam computed tomography. Methods: Mesiodistal angulations were measured on radiography. buccolingual inclinations determined tomography scans. previous measurements then through Pearson correlation coefficient. Results: results showed higher between mesiodistal 2D angulation 3D inclination, for first premolars, rather than 3D. Conclusion: Especially arches, root is not reliable; fact, it greatly influenced by inclination. Therefore, clinical evaluation highly recommended with provide correct diagnosis most satisfactory results.
