The aim of this study was to evaluate the response of rat subcutaneous tissue to MTA Fillapex® (Angelus), an experimental root canal filling material based on Portland cement and propylene glycol (PCPG), and a zinc oxide, eugenol and iodoform (ZOEI) paste. These materials were placed in polyethylene tubes and implanted into the dorsal connective tissue of Wistar rats for 7 and 15 days. The spec...

It is a worthy aim to preserve the pulp vitality in teeth with immature root in order to continue the root's maturation. Traumatic injuries and caries are two main reasons for pulp exposure in immature teeth. This article describes two vital pulp therapies on two patients, a nine-year-old boy with traumatized central tooth and a 10-year-old boy with caries exposure in a premolar tooth. Both tee...

The aim of this study was to establish the degree of tooth crown staining by commonly used endodontic sealers. Crown discolorations by tooth canal sealers [AH Plus (Dentsply DeTrey Gmbh, Konstanz, Germany); Endofill (Produits Dentaires SA, Vevey, Switzerland); Apexit (Dentsply DeTrey Gmbh, Konstanz, Germany); and MTA Fillapex (Angelus, Londrina, Brazil)] were tested on extracted human premolars...

background and aims. biocompatibility of root-end filling materials is a matter of debate. the aim of this study was to compare the biocompatibility of a variety of commercial proroot wmta cements and a resin-based cement (geristore®) with different ph values of setting reaction and different aluminum contents, implanted into the subcutaneous connective tissue of rats at various time intervals....

H d bstract his study assessed the ability of Portland cement, hite Angelus–mineral trioxide aggregate (MTA), and TA Bio to seal furcal perforations in extracted human olar teeth. Fifty-five human mandibular molar teeth ere accessed, and the canal orifices were located. The oots were horizontally sectioned in the middle third. esin composite was used to fill the root canal orifices nd the apica...

AIM The purpose of this investigation was to evaluate the marginal adaptation of five root-end filling materials. METHODS AND MATERIALS Fifty human single-rooted teeth were resected 3 mm from the apex. Root-end cavities were then prepared using an ultrasonic tip and filled with one of the following materials: silver amalgam without zinc, white MTA-Angelus, white Portland cement (PC), Vitremer...
