Summary
Herbal toothpaste with Little Ironweed and Java Tea effectively reduced dentine permeability, similar to nonherbal options. This suggests potential for treating dentine hypersensitivity.
Area of Science:
- Dentistry
- Biomaterials
- Oral Health
Background:
- Dentine hypersensitivity is a common clinical condition.
- Reducing dentine permeability is a key strategy for managing hypersensitivity.
- Herbal ingredients are increasingly explored for dental applications.
Purpose of the Study:
- To evaluate the efficacy of an herbal toothpaste containing Little Ironweed and Java Tea in reducing dentine permeability in vitro.
- To compare the effects of herbal toothpaste with nonherbal toothpaste and deionized water on dentine permeability.
Main Methods:
- Human dentine discs were treated with herbal toothpaste, nonherbal toothpaste, or deionized water.
- Dentine permeability was measured before and after immersion in artificial saliva or citric acid.
- Scanning electron microscopy (SEM) was used to observe dentine morphology.
Main Results:
- Both herbal and nonherbal toothpastes reduced dentine permeability.
- Artificial saliva further decreased permeability in toothpaste groups.
- Acid challenge increased permeability, with similar results for both toothpaste types.
- SEM showed particles occluding dentinal tubules in toothpaste groups.
Conclusions:
- Herbal toothpaste demonstrated comparable dentine permeability reduction to nonherbal toothpaste.
- Little Ironweed and Java Tea show potential in reducing dentine permeability.
- These herbal ingredients may help alleviate clinical hypersensitivity.
