Abstract

Aim: The aim of the present pilot study was to assess the preoperative cone-beam computed tomography (CBCT) images with prefabricated grids to locate the periapical pathosis in mandibular molars. Materials and methods: Two adult human cadavers in which mandibular first permanent molars were selected for this study were selected for this study. A stainless-steel grid has been precisely created. To support the grid, it was positioned along the long axis of teeth on the lingual side by using putty material. In both mandibles, Grid-based CBCT planning was used for the experimental group, while nonguided CBCT planning was used for contralateral counterparts in the same jaw. Postoperatively, CBCT image was superimposed on the preplanned drill path and imported to the DICOM file. Result: Average osteotomy sites for both the mandibles in experimental groups were 1.75 and 3.25 mm for the control group. Conclusion: The grid-guided approach for apical access is more precise than the conventional technique. This study proved that the grid is a more conservative and effective aid in endodontic microsurgery.
