Determination of optimal horizontal beam angulations for canal separation in mandibular molars using cone-beam computed tomography: a retrospective image-based analysis
A mesial beam angulation of 30° to 35° provides probable canal differentiation in mandibular molars, separating mesial canals in ≥99% and distal canals in ≥95% of cases. This range refines previous recommendations and supports the as low as reasonably achievable (ALARA) principle.
