A dog model was used to assess and compare in vivo the efficacy of gutta-percha and AH26 sealer versus Resilon with Epiphany primer and sealer [Resilon "Monoblock" System (RMS)] filled roots in preventing apical periodontitis subsequent to coronal inoculation with oral microorganisms. There were 56
Internal root resorption is a chronic inflammatory process initiated within the pulp space with the loss of dentin. This condition demands a comprehensive understanding of the pathologic process, so as to identify the cause and arrest the resorptive phenomena. It is a rare occurrence, asymptomatic,
Adsorption of some paraformaldehyde was noted in a previous study evaluating its sterilizing effect on gutta-percha (GP). This study examined histologically the effect of this adsorption when formaldehyde-exposed GP was implanted into the subcutaneous connective tissue of rats. GP implants were
This study examined histologically the effect of three sealers used with gutta-percha as root-end fillings placed in a replantation model. A total of 14 molar teeth were used in seven monkeys. After extraction, root ends were resected, the canals contaminated with oral bacteria, root-end cavities
Previous studies have shown that there is a proliferation of nerves beneath the apices of pulpectomized teeth. This may be due to the inflammation induced after the procedure, resulting, perhaps, from the irritant nature of the materials used to fill the root canal. The experiment reported here was
BACKGROUND
The purpose of this study was to evaluate the biocompatibility of a self-adhesive gutta-percha material and compare it with that of conventional gutta-percha.
METHODS
Standard quantities of bioactive gutta-percha and conventional gutta-percha were directly inserted subcutaneously into the
OBJECTIVE
The present report describes and discusses a nonsurgical technique for the removal of overextended gutta-percha.
BACKGROUND
Mechanical irritation results from overextension and the overextended material used during root canal obturation could produce an inflammatory reaction with an area
Nowadays Ag-points, gutta percha and amalgam are widely used as orthograde or retrograde root-filling materials. The biocompatibility of these materials however remains debatable. Ag-points are easy to manipulate and when used together with an appropriate cement, offer an adequate seal. Yet an

BACKGROUND
The aim of this study was to investigate in vivo biocompatibility of Resilon, compared with gutta-percha, at short and long-term following implantation in a rat subcutaneous implantation model.
METHODS
Male Wistar rats were implanted subcutaneously with either Resilon or gutta-percha or
The microanatomy of lateral periodontal tissues was examined after root canal obturation by a warm gutta-percha technique had been accomplished. Inflammatory responses were slight and of shot duration. The use of hot instruments for the condensation of the filling material did not appear to endanger
The thermoplasticized gutta-percha obturation technique is a relatively recent development in endodontics. In this study we evaluated the possible effects of heat transmitted to the periodontal tissues when the Obtura root canal filling device was used in dog teeth. Two 8-month-old beagle dogs were
Tissue healing was compared after apicectomy and filling of ferret lower canines with glass ionomer (Ketacfil) or gutta-percha/sealer (Tubliseal). Both materials provoked an inflammatory response after 7 days, but the response to glass ionomer was less severe. The response after 28 days was
OBJECTIVE
To analyse the healing response to gutta-percha and Diaket when used as root-end filling materials in periradicular surgery.
METHODS
Periradicular surgery was completed using the mandibular second, third and fourth premolar teeth from nine male mongrel dogs. The six roots on one side of
BACKGROUND
Gutta-percha (GP), is a neutral and non-toxic material. The aim of this animal study was to compare the biocompatibility of nanosilver coated GP (NS-GP) with conventional GP in subcutaneous tissues in a rat model.
METHODS
Conventional GP and NS-GP were subcutaneously implanted in the
