Antibacterial Effect Of A New Herbal Paste Used As An Intracanal Medication In Necrotic Primary Molars, A Randomized Control Trial

Abstract

Background synthetic intracanal medications have many side effects as toxicity and bacterial resistance.  Herbal intracanal medication has a superior antibacterial effect than synthetic medications. Aim This study aimed to compare the antimicrobial effect of a new herbal intracanal medication (Costus paste) with calcium hydroxide paste. Materials and methods This study was registered at clinicaltrial.gov under the number NCT05657132. Twenty-four children aged 4-7 years were randomly distributed into 2 groups (N=12), Group I: used Costus paste as an intracanal medication, group II: used Meta paste as an intracanal medication, 2 swabs were collected from the distal root of necrotic primary molars. One after access cavity opening and the second one, after applying intracanal medication for 1 week. Microbial testing of the swabs was done to count the amount of Enterococcus Faecalis bacteria. Results Costus Paste showed a higher statistically significant percentage of reduction of Enterococcus Faecalis bacteria when compared to Meta paste Conclusion Costus paste was a challenging intracanal medication that can safely substitute the synthetic intracanal medication.
