Aim and objective: This study aimed to evaluate the impact of coronal sealing ability of three temporary restorative materials called Orafil LC, Cavit-G, and Coltosol to prevent microleakage.
Materials and methods: Endodontic access cavities were prepared in 60 caries-free human extracted premolars. All 60 extracted teeth were divided into 3 experimental groups randomly and filled with Orafil LC, Cavit-G, and Coltosol into 4 mm deep cavities. The thermocycling process was performed and then all 60 teeth were immersed in 10% India ink at 37°C for 1 week. Teeth were sectioned buccolingually and a stereomicroscope was used to measure dye penetration. Data were analyzed using Fisher's exact test.
Results: There were significant differences present between Orafil LC, Cavit-G, and Orafil LC–Coltosol groups. The highest and lowest leakage scores were present in Coltosol and Orafil LC experimental groups, respectively.
Conclusion: Orafil LC showed better sealing ability compared to Cavit-G and Coltosol. The selection of temporary restorative material is very important for long-term endodontic treatment success.
Clinical significance: The importance of temporary restorative materials should not be ignored by a dental practitioner. Orafil LC showed better sealing ability compared to other materials.
