A Comparative Evaluation of Five Obturation Techniques in the Management of Simulated Internal Resorptive Cavities.

Abstract

Abstract
Background: This study was conducted for Comparative Evaluation of Five Obturation
Techniques in the Management of Simulated Internal Resorptive Cavities.
Material and methods: 50 freshly extracted, completely formed root apex human
maxillary central incisors were collected. Teeth were chosen for this research if they lacked
calcification, internal resorption, and a root canal filling. Ultrasonic cleaning removed
calculus and debris from the nearly 21 mm teeth that were recovered, which were then
placed in a saline solution for storage. The apical foramen was located by inserting a size
10 K-file into the prepared endodontic access in each tooth. Finally, the teeth were irrigated
with saline and 2.5% sodium hypochlorite solution after being instrumented with a master
apical file size 40 and the step-back technique up to size 80.
Results: Group III showed the highest percentage of gutta-percha plus sealer and guttapercha, and the fewest voids, which was statistically significant (P 0.000) when compared
to groups I and II for warm vertical compaction and II for lateral condensation, Group III
for Obtura II with System B, Group IV for E and Q plus with System B, and Group V for
Thermafil. Group II also had a significantly higher percentage of sealers (P 0.0001) in Table
1. Group V likewise displays a significantly higher void percentage (P 0.0001) than any
other group.
Conclusion: It can be established that the best obturation strategy for dealing with teeth
showing internal resorption is a combination of Obtura II and System B. When used to
restore teeth with internal resorption, Thermafil provided the lowest quality of obturation.
Similarly, the greatest sealer was shown with the lateral condensation approach, making it
inappropriate for the therapy of interior resorptive cavities.
