IN VITRO ANTIMICROBIAL ACTIVITY OF COCONUT SHELL LIQUID SMOKE AGAINST Candida albicans AND Lactobacillus acidophilus ATTRIBUTING TO ENDODONTIC TREATMENT FAILURE

L. acidophilus bacteria and C. albicans fungi are the most common microorganisms isolated from oral cavity of patients suffering post-treatment root canal endodontic infections. Chlorophenol Camphor menthol (ChM) is one antimicrobials used for sterilizer but it still has many flaws. Coconut shell liquid smoke (CS-LS) a natural product that an antimicrobial activity non-toxic chemical compounds humans. This study aims at determining minimum inhibitory concentration (MIC) bactericidal (MBC) Albicans comparing between CS-LC with commercial sterilization. The MIC MBC CS-LS were measured using 10 different concentrations ranging 10-100%. was determined by broth dilution method. All cultured on each agar media to determine its MBC. data analyzed comparative test Kruskall-Wallis post-hoc Mann-Whitney. 10% CSLS. Meanwhile, 50% CSLS 60% CS-LS. No significant difference in ChKM found. Thus, potential treatment failure. Further research should be conducted know other uses dentistry.
