Comparative Evaluation of Coronal Microleakage Associated with Different Intra-Orifice Barrier Protocols in Endodontically Treated Maxillary Anterior Teeth
Preventing coronal microleakage is crucial for long-term endodontic success; this ex vivo study compared the sealing performance of five intra-orifice barrier (IOB) material application protocols with that of a no-IOB control. Sixty maxillary anterior teeth were randomly assigned to six groups (n = 10): control, flowab...
