The Seal Quality of Two Bioceramic Materials Used as Retro-grade Filling Utilizing Different Compaction Techniques (An In-vitro Study)

Abstract

Aim: This aim of the current study is to measure the porosity index of two bioceramic materials using Manual versus Manual/Ultrasonic assisted condensation. Materials and methods: Sixty maxillary central incisors were used in the current research. Orthograde endodontic filling was performed followed by root tip excision perpendicular to long axis of the root. A 3 mm ultrasonic tip retrograde preparation was prepared. Samples were then divided into four groups (n=15). ProRoot MTA condensed manually, EndoSequence BC putty condensed manually, and both with and without ultrasonic assisted condensation. Porosity index for the root end filling was measured using CBCT. Results: No significant difference was found in ProRoot MTA porosity index between groups. For Manual condensation, the mean value was 1.559±0.628%, whereas for Manual/Ultrasonic assisted condensation, it was 1.711±0.706%. (p-value = 0.539). Meanwhile For Endo Sequence BC putty the mean value of porosity index was 2.915± 1.004% and 1.868±0.36% for Manual and Manual/Ultrasonic assisted condensation respectively (p<0.001) Conclusion: it was concluded that the utilization of Manual/Ultrasonic assisted condensation resulted in a noteworthy reduction in quality for the Endo Sequence BC putty utilized as a root end filling material.
