Abstract
Introduction
The purpose of this study was firstly to compare the impact of radiographs, cone-beam
computed tomographic (CBCT) imaging, and 3D Endo software (Dentsply Sirona, Ballaigues,
Switzerland) on the assessment of root canal anatomy and radiographic quality of endodontic
treatment and secondly to assess stress levels in the same cohort of residents performing
endodontic treatment.
Methods
Sixty patients requiring primary molar endodontic treatment were allocated randomly
into 3 groups: group 1 (n = 20), conventional radiographs (periapical radiography [PR]) only; group 2 (n = 20), PR and CBCT imaging; and group 3 (n = 20), PR, CBCT imaging, and 3D Endo software. All treatment was performed using
a standardized protocol. Residents completed a questionnaire to assess their stress
levels and usefulness of the imaging modality used. The radiographic quality of completed
cases was assessed by 2 experienced endodontists who were not involved in the supervision
of the cases being assessed.
Results
Groups 2 (CBCT imaging) and 3 (PR, CBCT imaging, and 3D Endo) proved significantly
better than group 1 (PR) (P < .001) for assessing the number of root canals and anatomy and estimating the working
lengths. Group 3 provided a significantly more accurate determination of the working
level (P = .002). There were significantly more cases with obturation short of the apex (<2
mm) and voids in group 1 compared with group 3 (P < .05) and a significantly higher number of cases with voids in group 1 compared
with group 3 (P < .01). Clinicians found treatment to be moderately or very stressful in 75%, 5%,
and 0% in groups 1, 2, and 3, respectively.
Conclusions
3D Endo software followed by CBCT imaging were found to be more desirable for the
evaluation of root canal anatomy and working lengths and reducing the residents' stress
levels.
