Comparative sealability study on root canal obturation using multiphase gutta percha and lateral condensation technique.

An in-vitro dye leakage study was performed to compare the apical microleakage of recently introduced multiphase obturation system to lateral condensation technique using methylene blue dye. Thirty single rooted human teeth were divided randomly into two equal groups. Group A were filled with multiphase technique using Tubliseal sealer and group B were filled with lateral condensation technique using the same sealer (control). Root canal preparation of both groups were carried out with nickel titanium files. Statistical analysis revealed that multiphase technique exhibited lower mean leakage (0.6) than lateral condensation technique (1.72). In addition some specimen filled with multiphase technique showed zero degree leakage.
