INTRODUCTION

Bacteria and their byproducts are key contributors to the onset and perpetuation of pulpoperiapical pathosis. Intracanal medication is vital in achieving successful endodontic outcomes as it targets and eradicates remaining microorganisms following biomechanical preparation.

AIM AND OBJECTIVE

The aim of the study was to compare and evaluate the antimicrobial efficacy of calcium hydroxide (CH) paste, triple antibiotic paste (TAP), and probiotics (PBs) as intracanal medicament in 12-17-year-old children undergoing root canal treatment for the management of infected pulpal tissues in young permanent teeth.

MATERIALS AND METHODS

A total of 30 patients aged 12-17 years indicated for endodontic therapy in maxillary incisors and with no systemic complications were selected. They were randomly divided into three groups, i.e., Group I - CH group, Group II - TAP, and Group III - PB allocating 10 teeth in each group. After access opening, the first sample (S1) was collected by inserting a paper point into the root canal, the second sample (S2) was collected immediately after biomechanical preparation, and the third sample (S3) was collected after 7 days, i.e., postintracanal medication. Samples were sent for microbiological analysis to assess the microbial count, and statistical analysis was done for the obtained data.

RESULTS

The three intracanal medicaments were successful in reducing the microbial counts of Enterococcus faecalis in the infected root canals. However, according to the results of the study, the PB group demonstrated greater effectiveness against E. faecalis compared to the CH group and displayed similar antimicrobial efficacy as the TAP group.

CONCLUSION

PB exhibited antimicrobial efficacy comparable to TAP but greater than Ca (OH) 2 paste. Hence, PB can be utilized as an intracanal medicament in young permanent teeth.
