In-vitro Evaluation of Microleakage in Root Canal Obturation with Mineral Trioxide Aggregate and Calcium-enriched Mixture Cement Using Fluid Filtration

Introduction: Endodontic treatment failure is caused by the leakage of microorganisms and endotoxins, which leads to pathological lesions. Adequate seal of the root canal is essential to preventing recontamination and ensuring the long-term clinical success rate. Mineral trioxide aggregate (MTA) and calcium-enriched mixture cement (CEM) are common types of cement with adequate ...

A Three-Dimensional Evaluation of Density and Homogeneity of Root Canal Obturation with Guttaflow® using Backfilling Technique in Comparison with Conventional Lateral Compaction Technique using Spiral Computed Tomography - An In Vitro Study

Comparative Evaluation of Sealing Ability, Water Absorption, and Solubility of Three Temporary Restorative Materials: An in vitro Study

Background: The quality of the coronal seal of root canal filling material is important for periapical health. Absorption of water or saliva by the temporary restorative materials leads to dimensional changes, loss of retention, staining and breaking in margin contours. Hence this study was carried out to evaluate and compare the sealing properties, water absorption and solubility of IRM (inter...

Root canal obturation and root integrity

The American Association of Endodontists defines root canal obturation as the complete, three-dimensional obturation of the root of canal system, as close as possible to the cemento-dentinal junction without overor underfilling. Moreover, obturation should be carried out using a minimal amount of biocompatible sealer and the obturated canal should demonstrate a radiographically dense filling ex...
