Summary
Zinc oxide/eugenol cement can cause pulpal irritation. Use protective liners or calcium hydroxide in deep cavities and before temporary cementation to prevent inflammatory reactions and protect dentinal tubules.
Area of Science:
- Dentistry
- Dental Materials Science
Background:
- Zinc oxide/eugenol cement is commonly used for temporary restorations.
- Pulpal irritation, including inflammation and cell aspiration, has been observed following its application.
Purpose of the Study:
- To investigate the pulpal response to zinc oxide/eugenol cement.
- To establish recommendations for minimizing pulpal irritation associated with its use.
Main Methods:
- Clinical observations of pulpal reactions after cement insertion.
- Evaluation of the effectiveness of protective liners and calcium hydroxide bases.
Main Results:
- Pulpal irritation occurs when zinc oxide/eugenol cement is used in deep cavities without protection.
- Calcium hydroxide liners effectively cover exposed dentinal tubules and mitigate irritation.
Conclusions:
- Temporary restorations with zinc oxide/eugenol cement require protective liners or calcium hydroxide in deep cavities.
- Proper dentin cleaning and the application of calcium hydroxide liners are crucial before temporary cementation of restorations.
