Objective: A complete three-dimensional filling of the root canal system is the primary goal of endodontic therapy. In the case of curved canals, obturating the entire root canal space is a concern and adjunctive techniques are required to attain so. This systematic review aims to understand the most effective obturation technique in curved root canals.
Methodology: A systematic literature search was undertaken in the databases MEDLINE Ovid (from 1946), Scopus, and Google Scholar, as well as a hand search of the references of included publications. Ex-vivo and in-vitro studies were also included. The risk of bias was assessed. Meta-analysis was performed comparing lateral condensation and thermoplasticized technique using microleakage as an outcome.
Results: A total of 15 studies were included for systematic review and 6 studies were included for meta-analysis. No significant difference was seen between the main comparison group Of Cold Lateral Condensation and thermoplasticized obturation techniques.
Conclusion: Both Cold lateral condensation and thermoplasticized technique have comparable microleakage and the comparison of void space in the individual studies also showed debatable results.
