Comparative evaluation of bacterial reduction at various stages of Endodontic Retreatment after the use of 2 percentage Chlorhexidine gel and modified triple antibiotic paste as Intracanal medicaments - A Non-Randomized Clinical Trial Study

Favorable outcome of non surgicalendodontic retreatment depends on the complete elimination of the microflorafrom the root canal system. But the conventional chemo-mechanical cleaning andshaping (i.e; using file system and irrigants) may not be successful enough toeliminate the flora and therefore needs the addition of suitable intracanalmedicament along with the conventional cleaning and shaping. The most commonly used Intracanal medicament is Calcium hydroxide, which is been used from a long time. But, Calcium hydroxide has several drawbacks such as: The high pH (11 to 12) might be toxic to the periapical gem cells, Inability/ resistance of many microorganisms against calcium hydroxide etc. Therefore, this necessitates the need for a better and more efficient intracanal medicament during retreatment procedures. The proposed studyis an interventional study which will be done to evaluate and compare the levelof  bacterial reduction between 2intracanal medicaments: 2% Chlorhexidine gel and modified triple antibioticpaste during non surgical endodontic retreatment. 26 participants will bedivided randomly into 2 study groups: group I will be getting 2% Chlorhexidinegel as the Intracanal medicament and group II will be getting freshly preparedmodified triple antibiotic paste. Three samples from each participants will becollected during various stages of the retreatment procedure and sent forcolony count calculation and evaluating the reduction in bacterial count.
