Figure 2

Preoperative radiographic assessment. (a) Straight-on and (b) angulated initial radiographs showing tooth #47 with deep occluso-mesial caries along with large pulp space situated within a single conical root. (c, d) Sagittal and coronal CBCT slices suggest the presence of one root canal configuration. (e–g) Further evaluation of the axial cuts in the coronal, middle, and apical thirds confirms the presence of Vertucci Type I canal system.
