Abstract
Introduction Bacteria and their products play a primary etiological role in the initiation and perpetuation of pulpoperiapical pathosis. Intracanal medication is important for endodontic success as it eliminates microorganisms that persist after chemomechanical preparation.Aim To compare antimicrobial efficacy of calcium hydroxide powder, triple antibiotic paste, calcium hydroxide with 2% chlorhexidine solution, and triple antibiotic paste with 2% chlorhexidine solution.Materials and methods A total of 48 nonvital primary teeth were included in this study. After access opening first microbiological sample (s1) was collected by using absorbent paper point introducing into canal. Second microbilogical sample (s2) was taken following chemomechanical preparation and the teeth were divided into four groups: Group I: calcium hydroxide (CH) powder with distilled water; group II: CH with 2% chlorhexidine solution; group III: triple antibiotic powder with distilled water; group IV: triple antibiotic paste with 2% chlorhexidine solution. Then the canals were filled with any one group of the medicament and cavity was temporarily sealed with zinc oxide eugenol. After 1 week, a postmedication sample (s3) was collected. Then the canal was filled with Metapex, restored with glass ionomer cement.Conclusion From the experiments carried out in this study, with the limitations, an inference can be drawn that a combination of antimicrobial agent used as intracanal medicament is definitely better than single agent like Ca(OH)2.How to cite this article Dutta B, Dhull KS, Das D, Samir PV, Verma RK, Singh N.

Chemomechani cal preparation has an important cleaning effect, it does not ensure the complete elimination of microorganisms present in the root canal system of primary teeth owing to their peculiar internal anatomy and the limitations of the instrumentation technique.[3,4]
The present study evaluated the antimicrobial effi cacy of a new combination medicament (TAP + calcium hydroxide (CH)) and compared with other combinations or CH alone against E. faecalis in necrotic primary teeth in in vivo conditions
Summary
Bacteria and their products play a primary etiological role in the initiation and perpetuation of pulpoperiapical pathosis. There is a similarity in the pathogens found in primary teeth to those in permanent teeth.[1] Reduction or elimi nation of the bacterial infection seems to be one of the important factors for the success of endodontic treatment of teeth with necrotic pulp.[2] chemomechani cal preparation has an important cleaning effect, it does not ensure the complete elimination of microorganisms present in the root canal system of primary teeth owing to their peculiar internal anatomy and the limitations of the instrumentation technique.[3,4] The remaining viable bacteria left in the root canal may multiply between appointments or following obturation often reaching a pathogenic level and leading to failure.[5] a suit able medicament is required to disinfect the root canal system prior to obturation so as to promote healing and prevent recurrence.[6]
