HUBBE, Karen Lys; OLIVEIRA, Kauhanna Vianna de; COELHO, Beatriz Serrato  e  BARATTO-FILHO, Flares. AH Plus extrusion into periapical tissue: literature review of main related properties and report of clinical cases. RSBO (Online) [online]. 2016, vol.13, n.4, pp. 280-288. ISSN 1984-5685.

Introduction: The sealers were developed for filling of root canals. Due to their physicochemical and technical properties used for obturation, often, extrusion is observed through apical constriction and occasionally by lateral and secondary canals. Objective: To review the literature on important properties to be considered in AH Plus sealer extrusion and report a case series of this sealer extrusion. Literature review: Articles evaluating the cytotoxicity and biocompatibility properties, besides flow and solubility were selected. Case report: In the presented cases, endodontic treatment was performed with rotary instrumentation and irrigation with 2.5% NaOCl. Obturation employed visual, tactile, and radiographic proof of gutta-percha main cone, and different obturation techniques. There were no reports of pain during and after endodontic treatment. Conclusion: AH Plus has adequate properties for a filling material and causes no major damage to the periapical tissues due to its little cytotoxic.
