Periapical repair after root canal filling with different root canal sealers
(2009-12-01)
The aim of this study was to evaluate periapical repair after root canal filling with different endodontic sealers. Sixty four root canals from dog ́s teeth were filled, divided into 4 groups (n=16). Root canals were ...
Effect of intracanal dressings on repair and apical bridging of teeth with incomplete root formation
(Munksgaard Int Publ Ltd, 1993-02-01)
Periapical repair and apical bridging were studied in dog's teeth with incomplete root formation and induced chronic periapical lesions treated with different dressings. A total of 75 root canals from the upper and lower ...
Effect of EDTA and QMIX ultrasonic activation on the reduction of microorganisms and endotoxins in ex vivo human root canals
(2019-05-01)
The present study aimed to compare the effectiveness of QMiX and 17% EDTA associated to passive ultrasonic irrigation (PUI) or manual agitation (MA) on the reduction of E. faecalis, E. coli and LPS from root canals. Forty ...
Cytotoxicity of root canal irrigating solutions and photodynamic therapy using curcumin photosensitizer
(2022-06-01)
Background: Photodynamic therapy (PDT) has shown satisfactory antibacterial effects. However, little information regarding the cytotoxicity potential of PDT using curcumin as a photosensitizer (PS) on fibroblasts are found. ...

The effect of final irrigation on the penetrability of an epoxy resin-based sealer into dentinal tubules: a confocal microscopy study
(2015)
Introduction The aim of this study was to compare the effect of QMix, BioPure MTAD, 17 % EDTA, and saline on the penetrability of a resin-based sealer into dentinal tubules using a confocal laser scanning microscope (CLSM) ...
Debris and smear removal in flattened root canals after use of different irrigant agitation protocols
(WILEY-BLACKWELLHOBOKEN, 2012)
Scanning electron microscopy (SEM) can be used to analyze the presence of debris and smear layer on the internal walls of root canal. This study evaluated the debris and smear removal in flattened root canals using SEM ...
