The Influence of Different Mouthwashes on the Efficacy of Fluoridated Dentifrices in the Prevention of Enamel Erosion: An In Vitro Study

https://pubmed.ncbi.nlm.nih.gov/38152902/

Introduction

Enamel erosion is a prevalent dental problem caused by various factors such as acidic food and drinks, improper oral hygiene, and medical conditions. To combat enamel erosion, fluoride dentifrices have been widely used for their preventive effects. However, the influence of different mouthwashes on the efficacy of fluoridated dentifrices in preventing enamel erosion has not been extensively studied. 

Study Findings

Recently, an in vitro study was conducted to determine the impact of various mouthwashes on the preventive effects of fluoride dentifrices against enamel erosion. The study compared different mouthwashes with varying compositions and major constituents to evaluate their influence on tooth surface loss. The results revealed some interesting findings.

The study concluded that the preventive effects of fluoride dentifrices against tooth surface loss remained unaffected by the use of different mouthwashes. This means that regardless of the mouthwash used, the fluoride toothpaste effectively protected against enamel erosion. 

Furthermore, the study found that toothpaste containing stannous fluoride provided better surface loss protection than toothpaste containing sodium fluoride. Stannous fluoride is well-known for its superior anti-erosive properties, making it more effective in preventing enamel erosion.

Clinical Significance

The findings of this study have significant clinical implications for dental practitioners and individuals seeking to prevent enamel erosion. The primary strategy for preventing enamel erosion is through primary prevention and eradicating contributing causes. This includes maintaining proper oral hygiene, consuming a balanced diet, and avoiding acidic food and drinks.

Additionally, the study suggests that antibacterial agents present in mouthwashes may enhance the effect of fluoride in the enamel due to their high affinity for tooth structures. This implies that using an antibacterial mouthwash alongside fluoride dentifrices may provide an added protective effect against enamel erosion.

However, it is important to note that while using an appropriate mouthwash can contribute to enamel protection, it should not replace the importance of cause-related treatment. Efforts should be made to reduce tooth tissue loss in addition to using preventive measures such as fluoride toothpaste and mouthwash.

Conclusion

Enamel erosion is a common dental issue that can be prevented through various strategies, including the use of fluoride dentifrices. The recent in vitro study on the influence of different mouthwashes on the efficacy of fluoride dentifrices provided valuable insights.

The study found that regardless of the mouthwash used, fluoride toothpaste effectively protected against enamel erosion. Additionally, toothpaste containing stannous fluoride was more effective in preventing enamel erosion than toothpaste containing sodium fluoride. Furthermore, the study highlighted the potential for antibacterial mouthwashes to enhance the protective effect of fluoride on enamel.

These findings emphasize the importance of preventive measures and cause-related treatment in reducing enamel erosion. Dental professionals should educate their patients about the benefits of fluoride dentifrices and the additional protective effect that an appropriate mouthwash can provide. By following these recommendations, individuals can maintain strong and healthy enamel, ensuring long-lasting dental health.
