Regenerative endodontics aims to replace inflamed/necrotic pulp tissues with regenerated pulp-like tissues to revitalize teeth and improve life quality. Pulp revascularization case reports, which showed successful clinical and radiographic outcomes, indicated the possible clinical application of pulp regeneration via cell homing strategy. From a clinical point of view, functional pulp-like tiss...

INTRODUCTION Root canal irrigation carries a risk of extrusion of irrigant into the periapical tissues. The objective of this study was to compare different irrigation systems in matched pairs of teeth prepared to an apical size of 35.06 and 50.06 by measuring the frequency and extent of apical extrusion of sodium hypochlorite (NaOCl) into a simulated periapical environment. The null hypothesis...

INTRODUCTION The extrusion of irrigation solutions beyond the apical constriction may result in postoperative pain. Sodium hypochlorite can cause severe tissue irritation and necrosis outside the root canal system if extruded into the periodontal ligament (PDL) space. Different delivery techniques were discussed to reduce this potential risk. The aim of this study was to compare the postoperati...

INTRODUCTION The aim of this study was to evaluate the outcome of single- versus 2-visit root canal treatment of teeth with apical periodontitis after a 2-year follow-up period. METHODS Three hundred maxillary and mandibular nonvital teeth with apical periodontitis were treated in either a single visit or 2 visits. The main inclusion criteria were radiographic evidence of apical periodontitis...

Anastomotic dehiscence in rectal cancer is one of the most feared complications. In the long term, a presacral sinus can form that is difficult to manage. The advent of biological tissue adhesives for the treatment of complex fistulas can be an effective alternative for this type of complication. We present a case of anastomotic dehiscence after low anterior resection and the later formation of...
