ABSTRACT
BACKGROUND: Periodontitis is an inflammatory disease resulting in the destruction of periodontal tissues. Various treatment modalities have been tried in the form of mechanical therapy and surgical therapy. Antimicrobial agents have been used as a monotherapy and as an adjunct with mechanical debridement. Various plant extracts have been used as antibacterial agents. Pineapple extract (bromelian) is one such agent. Hence this study was conducted to assess the antibacterial efficacy of bromelain on both aerobic and anaerobic periodontal microorganisms. The aim was to assess the antibacterial efficacy of bromelain on both aerobic and anaerobic periodontal microorganisms. MATERIALS AND METHODS: Minimum inhibitory concentration (MIC) of bromelain was tested on isolated strains of Streptococcus mutans, Enterococcus fecalis Aggregatibacter actinomycetemcomitans (Aa), and Porphyromonas gingivalis (Pg) using serial dilution broth method. RESULTS: S. mutans showed sensitivity at the lowest concentration of 2 mg/ml as compared to E fecalis (31.25 mg/ml) while Pgingivalis showed sensitivity at the lowest concentration of 4.15 mg/ml as compared to Aa (16.6 mg/ml). CONCLUSION: Bromelain exerts an antibacterial effect against potent periodontal pathogens; hence, it may be used as an antibacterial agent. However, further trial has to be conducted to validate this result.
