The aim of this in vitro study was to evaluate the influence of endodontic therapy, veneer preparation, and their association on fracture resistance and deflection of pulpless anterior teeth and assess whether restoration with quartz fiber-reinforced post can influence these properties. Seventy-five freshly extracted human maxillary central incisors were selected. Teeth were randomly divided in...

Up to 80% of endodontic patients who report with preoperative pain continue to experience some level of pain following the endodontic procedure. Since endodontic pain is often associated with chronic inflammation, the presence of bacterial by-products, influx of primed immune cells and activation of the cytokine network and other inflammatory mediators, pain may be reduced by administration of ...

Irrigation of root canals during endodontic therapy is an important step. Sodium hypochlorite (NaOCl), hydrogen peroxide (H2O2), chlorhexidine (CHX) and normal saline are commonly used intracanal irrigants to disinfect and clean the root canals. This prospective study was set to observe the efficacy of normal saline (0.9% NaCl) irrigation with sequential irrigation of 3% H2O2, 5.2% NaOCl and 0....
