Comparison of the Effectiveness of Tea Tree Oil Mouthwash 0.25% and Chlorhexidine Gluconate 0.2% Against the Growth of Staphylococcus Aureus Bacteria

Introduction

Staphylococcus aureus is a pathogenic bacterium that is commonly found and known as the main cause of various oral cavity infections, such as angular cheilitis, parotitis, and staphylococcal mucositis. To prevent the infection caused by this bacterium, one of the methods that can be done is to use antiseptic mouthwash. Among the choices, chlorhexidine gluconate is the most widely used mouthwash thanks to its ability to inhibit the growth of oral pathogens. However, the long-term use of chlorhexidine can cause side effects, one of which is dental discoloration.

The Need for Alternative Antiseptic Mouthwashes

As an alternative to chlorhexidine gluconate, tea tree oil or melaleuca alternifolia is an essential oil that is known to have extensive antibacterial activity. This study aims to compare the effectiveness between the Tea Tree Oil mouthwash 0.25% and 0.2% chlorhexidine gluconate in inhibiting the growth of Staphylococcus aureus bacteria. The use of tea tree oil as an alternative antiseptic mouthwash is gaining popularity due to its potential to provide similar antibacterial effects without the side effects associated with long-term use of chlorhexidine.

Methodology

The method used in this study is the Kirby-Bauer disc-diffusion method, where Staphylococcus aureus is incubated on the Muller Hinton Medium (MHA). Paper discs containing test materials are placed on the surface of the medium, and after incubating for 24 hours at 37°C, the diameter of the inhibition zone is measured to determine the effectiveness of each solution. The test materials used in this study include Tea Tree Oil mouthwash 0.25%, 0.2% chlorhexidine gluconate, and 0.9% NaCl solution as a control.

Results

The results of this study showed that the average diameter of the inhibition zone for the Tea Tree Oil mouthwash 0.25% was 9.60 mm with a standard deviation of 0.8231 mm, while for chlorhexidine gluconate 0.2% was 13.30 mm with a standard deviation of 0.4924 mm. As a comparison, the 0.9% NaCl solution shows an average inhibition zone of 6.00 mm. The results of this study indicate that chlorhexidine gluconate 0.2% is more effective in inhibiting the growth of Staphylococcus aureus compared to Tea Tree Oil 0.25%.

Discussion

The results of this study suggest that although Tea Tree Oil has a good antibacterial ability, chlorhexidine gluconate is still a more effective choice for overcoming infections caused by Staphylococcus aureus. However, it is essential to consider the long-term side effects of the use of chlorhexidine, so the use of tea tree oil as an alternative can be considered especially for those who want to avoid this risk. With this understanding, the choice in the use of antiseptic mouthwash can be done wisely based on long-term effectiveness and safety.

Conclusion

In conclusion, this study has shown that chlorhexidine gluconate 0.2% is more effective in inhibiting the growth of Staphylococcus aureus compared to Tea Tree Oil 0.25%. However, the use of tea tree oil as an alternative antiseptic mouthwash can be considered especially for those who want to avoid the side effects associated with long-term use of chlorhexidine. Further studies are needed to investigate the long-term effects of tea tree oil on oral health and to determine its potential as a replacement for chlorhexidine gluconate.

Recommendations

Based on the results of this study, the following recommendations can be made:

Chlorhexidine gluconate 0.2% can be used as an effective antiseptic mouthwash for preventing infections caused by Staphylococcus aureus.
Tea Tree Oil 0.25% can be used as an alternative antiseptic mouthwash for those who want to avoid the side effects associated with long-term use of chlorhexidine.
Further studies are needed to investigate the long-term effects of tea tree oil on oral health and to determine its potential as a replacement for chlorhexidine gluconate.

Limitations

This study has several limitations, including:

The study only investigated the effectiveness of Tea Tree Oil 0.25% and chlorhexidine gluconate 0.2% against Staphylococcus aureus.
The study did not investigate the long-term effects of tea tree oil on oral health.
The study did not compare the effectiveness of tea tree oil with other antiseptic mouthwashes.

Future Directions

Future studies can investigate the following:

The long-term effects of tea tree oil on oral health.
The effectiveness of tea tree oil against other oral pathogens.
The comparison of the effectiveness of tea tree oil with other antiseptic mouthwashes.
