Summary
Caviton and Cavit offered superior microleakage sealing compared to IRM in root canal treatments. Cavit performed better than IRM across tested powder-to-liquid ratios, highlighting material choice importance for dental restorations.
Area of Science:
- Endodontics
- Dental Materials Science
- Restorative Dentistry
Background:
- Effective coronal seal is crucial for endodontic treatment success.
- Material selection for temporary restorations and sealing access cavities impacts treatment longevity.
- Microleakage can lead to bacterial contamination and failure of endodontic therapy.
Purpose of the Study:
- To compare the microleakage of three temporary filling materials: Caviton, Cavit, and IRM.
- To evaluate the effect of two powder-to-liquid ratios (6 g/ml and 2 g/ml) on the sealing ability of these materials.
- To determine the optimal material and ratio for preventing microleakage in endodontic access preparations.
Main Methods:
- 140 human molar teeth underwent endodontic access preparations.
- Teeth were divided into groups, including positive and negative controls.
- Microleakage was assessed using basic fuchsin dye penetration after 100 thermal cycles (5-55°C).
Main Results:
- Caviton demonstrated the best overall sealing performance.
- Cavit exhibited significantly better sealing than IRM at both tested powder-to-liquid ratios (p < 0.05).
- No significant difference in sealing was found between the two powder-to-liquid ratios for IRM.
Conclusions:
- Caviton and Cavit are superior to IRM for sealing endodontic access preparations.
- Material choice significantly influences the effectiveness of the coronal seal.
- Further research may explore long-term sealing efficacy and other properties of these materials.
