Abstract

Background:  Calcium-hydroxide is still the most widely used intra-canal medicament. However, placement of an intra-canal medicament possess a great challenge for the clinicians when it comes to its removal from the canal system prior to obturation, & this removal becomes even more difficult when an oil based Ca(OH)2 formulation is used, regardless of the irrigants & agitation methods used. Aim: The aim of present in vitro study was to comparatively  evaluate  the efficacy of different irrigants for the removal of iodoform based  calcium hydroxide medicament from root canals. Methods & material:50 extracted mandibular premolars were  selected for the study. Cleaning and shaping was done and teeth were filled with oil based Ca(OH)2 formulation. After 7 days Ca(OH)2  was retrieved using  17% EDTA aqueous solution, 17% EDTA gel & 2.5% NaOCl in combination with sonic agitation. The samples were split longitudinally and scored under stereomicroscope. The results were statistically analyzed using  Kruskalwall is test and Mann-Whitney U test  Results: Among all experimental groups, EDTA gel when used with NaOCl with sonic agitation proved  superior significantly. Conclusion: Under the limitations of present study it can be advocated that neither irrigating solutions removed the medicament from walls of root canals completely.
