Abstract
Aim: The purpose of this study was to evaluate the adequacy of three different obturation techniques namely, the conventional lateral compaction, warm vertical compaction (SybronEndo, System B) and a core carrier obturation technique (DENTSPLY, GuttaCore) using three-dimensional Cone beam computed tomography (Care Stream CS 9000 3D CBCT) to measure the pulp space volume. Materials and Methods: The study sample comprised of 30 freshly extracted human mandibular and maxillary single-root premolars which were randomly divided into three groups of 10 teeth each. Biomechanical preparation was done in all teeth using WaveOne primary reciprocating files. All three sets of teeth were imaged in Cone Beam Computed Tomography (CBCT) scanner before and after obturation. Volume of the pulp space before and after obturation were calculated using OnDemand3D software and adequacy of the obturation techniques were measured by calculating the percentage differences of the obturated volume between the groups. Results: The data statistically analyzed using One-way ANOVA and Multiple-Range Tukey Test. There was a statistically significant difference in the obturated volume of the root canal space between the Gutta Core group and the lateral condensation group. Conclusions: Non obturated space (voids) was seen in all three obturation techniques. GuttaCore obturators showed the greater percentage of volume (POV) of obturation followed by the system B then the lateral condensation techniques.
Highlights
The purposes of obturating the prepared root canal space are to eliminate all avenues of leakage from the oral cavity or the periradicular tissues into the root canal system and to seal within the system any irritants that cannot be fully removed during canal cleaning and shaping procedures.To achieve this goal, it is believed that root canal fillings must seal the pulp space both apically and laterally to prevent further apical irritation from incomplete elimination of bacterial products or continuous communication between apical tissues and oral cavity [1].Cold Lateral condensation with Gutta Percha is a well-recognized technique and has been the one of choice by many dental practitioners for decades

Summary
The purposes of obturating the prepared root canal space are to eliminate all avenues of leakage from the oral cavity or the periradicular tissues into the root canal system and to seal within the system any irritants that cannot be fully removed during canal cleaning and shaping procedures. Cold Lateral condensation with Gutta Percha is a well-recognized technique and has been the one of choice by many dental practitioners for decades. It serves as the gold standard by which we judge other techniques [2]. It has shown that the thermoplastic techniques have certain superiority in producing well dense gutta-percha, compared to cold techniques [3]
