Obturation

The clinical goal of endodontic obturation of a root-canal system is to fill empty spaces, promote hermetic sealing, and prevent bacterial activity from infiltrating the periapical tissues.⁴³ Although gutta-percha has been a consistent material used in canal obturation for the last 40 years, techniques and sealers have changed during that time. Various techniques, such as lateral compaction, warm vertical compaction, and carrier-based obturation, have been reported in the scientific literature.^44,45 In regard to sealers, the most current trend is the bioceramic sealer.⁴⁶ It has been reported that bioceramic sealers are nontoxic, are hydrophilic, expand upon setting, and are antimicrobial.⁴⁷
