Antibacterial Effects of Pineapple Extracts on Bacteria that Cause Periodontal Disease

Pineapple has been a staple in the Indonesian diet for centuries, not only for its delicious taste but also for its rich content of active compounds such as bromelain, flavonoids, and vitamin C. These compounds have been shown to have potential as antimicrobial agents, and recent research has demonstrated that pineapple extract can provide antibacterial effects on various types of bacteria, particularly those associated with periodontal disease.

The Antimicrobial Potential of Pineapple Fruit

Bromelain, a key component of pineapple, has been found to reduce bacterial cell membrane tension and hydrolyze peptide bonds to amino acids, resulting in damage to bacterial cells and contributing to bacterial death. Flavonoids, another component of pineapple, play a role in damaging the structure of bacterial cells, leading to cell death. Meanwhile, vitamin C functions as an inhibitor of enzyme activity and protein transportation through cell membranes. These properties make pineapple a promising natural remedy for various bacterial infections.

The Role of Periodontal Disease in Oral Health

Periodontal disease, including periodontitis, is a chronic inflammatory condition caused by the collection of microorganisms, especially bacteria, in dental plaque and mucosa. This can lead to damage to the tooth buffer tissue and ultimately result in tooth loss. The two pathogenic bacteria often associated with periodontal disease are Porphyromonas gingivalis and Fusobacterium nucleatum. These bacteria are responsible for the destruction of periodontal tissues and the progression of periodontal disease. Therefore, the search for alternative treatments through natural ways, such as pineapple extract, is crucial in preventing and treating periodontal disease.

Research Objectives

This study aims to evaluate the minimum inhibitory level (KHM) and the minimum killing level (KBM) of pineapple extract on Porphyromonas gingivalis and Fusobacterium nucleatum at various extract concentrations. The concentrations tested included 50%, 25%, 12.5%, 6.25%, 3.125%, 1.56%, and 0.78%. The research objectives are to determine the effectiveness of pineapple extract as an antibacterial agent against these two types of bacteria and to identify the optimal concentration of extract that can inhibit bacterial growth.

Methodology

This research was conducted using an experimental laboratory design with a posttest control group. The effectiveness of pineapple extracts was tested through dilution methods, where extracts were made using maceration techniques and added to bacterial suspensions for each concentration. The experiment was repeated three times, and observations were made for each concentration. Data analysis was carried out using the One Way Anova test and the T test was not paired to determine whether there was a significant antibacterial effect of the pineapple extract on the tested bacteria.

Research Results

The results of the study showed that the KHM concentration for bacteria Porphyromonas Gingivalis ATCC 33277 was 12.5%, while KBM was 25%. For bacteria Fusobacterium Nucleatum ATCC 25586, KHM was obtained at a concentration of 25% and KBM at 50%. The T test was not paired, and it also showed a significant difference in effect (p <0.05) between pineapple extract and the growth of the two types of bacteria.

Conclusion

From this study, it can be concluded that pineapple extract has the potential as an effective antibacterial agent against Porphyromonas gingivalis and Fusobacterium nucleatum. With the increasing concentration of extracts, the greater the antibacterial effect. This indicates that the use of pineapple extract can be an alternative in the prevention and treatment of periodontal diseases naturally. In addition to increasing knowledge in the field of dental health, the results of this study also open up opportunities for further research on the use of natural ingredients in the treatment of infectious diseases.

Implications of the Study

The findings of this study have significant implications for the prevention and treatment of periodontal disease. The use of pineapple extract as an antibacterial agent can provide a natural and effective alternative to conventional treatments. Furthermore, the study highlights the potential of natural ingredients in the treatment of infectious diseases, which can lead to the development of new and innovative treatments.

Future Research Directions

Future research should focus on the optimization of pineapple extract concentrations and the identification of the active compounds responsible for the antibacterial effects. Additionally, studies should be conducted to evaluate the efficacy of pineapple extract in preventing and treating periodontal disease in humans. The results of this study also open up opportunities for further research on the use of natural ingredients in the treatment of infectious diseases, which can lead to the development of new and innovative treatments.

Limitations of the Study

This study has several limitations. The experiment was conducted in a laboratory setting, and the results may not be generalizable to humans. Additionally, the study only evaluated the antibacterial effects of pineapple extract on two types of bacteria, and further research is needed to evaluate its effects on other types of bacteria. Finally, the study did not evaluate the long-term effects of pineapple extract on periodontal disease, and further research is needed to determine its efficacy in preventing and treating periodontal disease in humans.

Conclusion

In conclusion, this study demonstrates the potential of pineapple extract as an effective antibacterial agent against Porphyromonas gingivalis and Fusobacterium nucleatum. The results of this study highlight the importance of natural ingredients in the treatment of infectious diseases and provide a foundation for further research on the use of pineapple extract in the prevention and treatment of periodontal disease.
