| description | Introduction: The restricted access cavity and the remaining
roof of the pulp chamber may change the angle at which the
instrument enters the root canal, which could have an impact
on the effectiveness of chemo-mechanical canal preparation,
potentially leading to endodontic mishaps.
Aim: To evaluate the effect of the Traditional Endodontic
Cavity (TEC) and Conservative Endodontic Cavity (CEC) on the
amount of Root Dentin Removal (RDR) and the related Apical
Debris Extrusion (ADE) in the curved root canals prepared with
ProTaper Next (PTN) and TruNatomy (TN).
Materials and Methods: The in-vitro study included a total of
120 extracted human mandibular molars, separated into four
groups (n=30) based on the type of endodontic cavity and
file used: TEC-TN, CEC-TN, TEC-PTN, and CEC-PTN. Before
biomechanical preparation, Cone Beam Computed Tomography
(CBCT) scans were taken. During the preparation, apically
extruded debris was collected in Eppendorf tubes. After canal
preparation, a post-CBCT scan was performed, and the RDR
was evaluated by comparing the pre- and post-CBCT scans. To
determine the amount of ADE, the weight of the clear tubes was
subtracted from the weight of the tubes containing the debris.
The data were analysed using one-way analysis of variance and
post-hoc Tukey test. The significance level was set at p<0.05.
Results: Analysis and comparison of four groups each with
n=-30 extracted mandibular molars was done in the present
study. The CEC-PTN group showed the highest total RDR of
0.32. Additionally, the CEC-PTN group produced the highest
ADE with statistically significant differences between the TECTN, CEC-TN, and TEC-PTN groups (p<0.05).
Conclusion: The CEC causes engagement of the rotary
instrument with the dentinal wall, leading to RDR, debris
production, and ultimately more ADE compared to TEC. The
TN file caused less RDR and ADE in both endodontic access
cavities compared to the PTN file. |
