Microbiological effect of different intracanal medicaments

The effect of Triple antibiotic paste (TAP), Modified triple antibiotic paste (MTAP) and its combination with Himalayan pink rock salt (HPRS) against Enterococcus faecalis is of interest to dentists. Intracanal medicaments were placed on specimens infected with EF and incubated. Antibacterial efficacy was evaluated by colony forming unit method on the 1st, 3rd, and 7th day. MTAP + HPRS showed the best results against E. faecalis on days 1 and 3 which were statistically significant. All subgroups showed zero colonies on day 7. HPRS combined with TAP/MTAP showed more antibacterial activity than TAP/MTP used without HPRS as intracanal medicament due to its synergistic effect. Hence, a modified triple antibiotic mixed with Himalayan pink rock salt can be used as a potential intracanal medicament with 2% Chlorhexidine.
