Evaluating the Thickness of the Root Canal Dentin Wall in Primary First Molars Using Cone-beam Computed Tomography.

Aim: To evaluate the thickness of the root canal dentin wall in the cervical, middle, and apical third of primary first molars.

Materials And Methods: Cross-sectional study consisting of 30 cone-beam computed tomography (CBCT) images of primary maxillary and mandibular first molars, with crown, and root integrity. The wall dentin thickness of each canal was measured in three axial views, divided into distal (D), mesial, lingual/palatine, and buccal surfaces.
