Evaluation of Antibacterial Activity of Three Selected Fruit Juices on Clinical Endodontic Bacterial Strains

INTRODUCTION: The increasing problem of antibiotic drug resistance by pathogenic microorganisms in the past few decades has recently led to the continuous exploration of natural plant products for new antibiotic agents. Many consumable food materials have good as well as their bad effects, good effect includes their antibacterial effects on different microorganisms present in the oral cavity. Recently, natural products have been evaluated as source of antimicrobial agent with efficacies against a variety of microorganisms. METHODOLOGY: The present study describes the antibacterial activity of three selected fruit juices (Apple, Pomegranate and Grape) on endodontic bacterial strains. Antimicrobial activity of fruit juices were tested by wel l diffusion assay by an inhibition zone surrounding the well. The aim of the study was to evaluate the antibacterial activity of three fruit juises on different endodontic strains. RESULT: Agar well diffusion method was adopted for determining antibacterial potency. Antibacterial activity present on the plates was indicated by an inhibition zone surrounding the well containing the fruit juice. The zone of inhibition was measured by measuring scale in millimeter. Comparision between antibacterial efficacy of all three fruit juices against Enterococcus feacalis and Streptococcus mutans was observed with significant value of P ≤ 0.05. CONCLUSION: The results obtained in this study clearly demonstrated a significant antimicrobial effect of apple fruit juice against Enterococcus fecalis and Streptococcus mutans. However, preclinical and clinical trials are needed to evaluate biocompatibility & safety before apple can conclusively be recommended in endodontic therapy, but in vitro observation of apple effectiveness appears promising.
