(PR10) Comparison of the Planmeca Promax 3D Mid and the Carestream 8100 3D CBCT Systems in Detecting Vertical Root Fractures

Abstract:

Objective: The purpose of this study was to compare the accuracy of the Planmeca Promax 3D Mid with the Carestream 8100 3D cone beam computed tomography (CBCT ) systems on identifying vertical root fractures in extracted human canines with and without root canal treatment. Materials and

Methods: Forty human canine teeth were collected and inspected under a lighted microscope for the absence of vertical root fractures. These teeth were accessed and instrumented with the ProTaper Gold rotary system to size F3, then divided into two experimental groups (fractured-nonfilled and fractured-filled) and two control groups (nonfractured-filled and nonfractured-nonfilled). Warm vertical compaction was performed with Kerr sealer. Vertical root fractures were induced in the experimental groups by applying force via pliers. Teeth were mounted into acrylic casts and scanned using the Planmeca Promax 3D Mid and Carestream 8100 systems. Two observers reviewed these scans to identify if a vertical root fracture could be visualized in the axial, coronal, or sagittal views.

Results: There was no statistically significant difference in accuracy of identifying vertical root fractures between the Planmeca Promax 3D Mid and the Carestream 8100 3D CBCT systems using a Chi-square test in the axial, sagittal, and coronal planes.

Conclusion: The Planmeca Promax 3D Mid and the Carestream 8100 3D cone beam computed tomography systems showed similar accuracy in detecting vertical root fractures in human canines.
