Abstract:
A Root Canal (RC) obturation that fully occupies that prepared canal space
contributes to treatment success. Invasive methods that involve sectioning of
treated teeth have been used evaluate the quality of RC obturation. The aim of
this study was to measure the amount of filling material in RC treated teeth
using imaging methods: Cone Beam Computed tomography (CBCT) and 3D
volumetric imaging software. These methods will be applied in an analysis of
both Warm Vertical (WV) and Cold Lateral (CL) obturation methods. This noninvasive
approach may be a preliminary step for future in vivo research. A
noninvasive 3D imaging method was able to measure volume of RC fillings.
Canals filled using WV contained a greater percentage of empty space than
canals filled using the CL method in this study. This method could prove to be
an efficient, cost effective tool for evaluating obturation material.
