Apical Sealing Ability of Experimental Apatite Calcium Phosphate based Coated Gutta-percha Points

Aims: This study aimed to assess the apical sealing ability of experimental apatite-coated gutta-percha points compared various coated root filling materials.
 Study Design: Experimental in-vitro study.
 Place and Duration Study: Department Restorative Dentistry, University Malaya, June 2014 November 2014.
 Methodology: Ninety-six extracted permanent maxillary central incisors were standardized prepared by ProTaper universal rotary files. The specimens allocated into six groups (n=15) filled using matching single cone technique as follows; EndoREZ with sealer, Bioceramic (BCGP), Active GP (ActiV GP), Conventional (GP), apatite (HAGP) all in combination Endosequence BC sealer. sixth group was cold lateral compaction subjected a dye leakage test. remaining teeth divided equally be used negative positive control. One-way analysis variance (ANOVA) followed post hoc Dunnett T3 test performed for data analysis, significance value set at P =.05.
 Results: ActiV had least BCGP, HAGP, compaction, conventional GP, EndoRez.
 Conclusion: HAGP canal showed favourable comparable it superior EndoREZ.
