Nonsurgical management of a large periapical lesion using aspiration in combination with a triple antibiotic paste and calcium hydroxide

Iranian Endodontic Journal, 2010
Persistent microorganisms in the root canal are known to cause endodontic treatments failure. Overextended gutta-percha can also act as a periradicular tissue irritant, leading to large periapical lesions.

An In Vitro Assessment of Gutta-Percha Coating of New Carrier-Based Root Canal Fillings

The Scientific World Journal, 2014
The first aim of this paper was to evaluate the push-out bond strength of the gutta-percha coating of Thermafil and GuttaCore and compare it with that of gutta-percha used to coat an experimental hydroxyapatite/polyethylene (HA/PE) obturator.

Dissolving efficacy of some organic solvents on gutta-percha Eficácia dissolvente de alguns solventes orgânicos sobre a guta-percha

Brazilian Oral Research, 2007
The aim of this study was to evaluate the solubility of gutta-percha in four organic solvents used in endodontics. The solubility of gutta-percha (Dentsply) was assessed in xylol, orange oil, eucalyptol, chloroform and distilled water.

Comparative evaluation of fracture resistance of teeth obturated using three different systems – AH plus/Gutta-percha, Resilon/Realseal self-etch, and Endofill/Gutta-percha: An in vitro study

Journal of Oral Research and Review, 2016
Introduction: Endodontically treated teeth are more prone to fracture under masticatory forces. Resin-based dental materials have been proposed as a means to reinforce an endodontically treated tooth through the use of adhesive sealers in the root canal ...
