Aim: To evaluate the surface alterations of soft liners with or without sealer coating after mechanical brushing abrasion. Methods: Thirty specimens were made of a methacrylate(Coe-Soft) and a siloxane-based material (Ufi-Gel SC), and 15 received two coatings of surface sealer. The specimens were submitted to a mechanical brushing-dentifrice assay under 200 g of force at 250 cycles/min. Mechani...

Abstract:
 Introduction: Bioceramic technology has been introduced recently in endodontics to benefit from the hydroxyapatite formation during setting reaction presence of tissue fluid and establish a chemical bond at dentin interface.
 Aim: To compare physiochemical properties (pH changes, releasing elements solubility) different newer sealer (Ceraseal) with mineral trioxide aggregat...

INTRODUCTION The purpose of this study was to evaluate the effects of different solutions used for final irrigation on sealer penetration into dentinal tubules. METHODS Thirty-two recently extracted human mandibular premolar teeth were treated with sodium hypochlorite (NaOCl) irrigation. The samples were divided into 4 groups according to the final irrigation solution used: (1) the EDTA group...

BACKGROUND Through chemomechanical debridement of the root canal is a primary requisite for successful endodontic therapy. Thus the aim of this study was to evaluate the effects of using QmiX alone, QmiX with EndoActivator and QmiX with Er,Cr:YSGG laser for final irrigation on sealer penetration into the dentinal tubules. MATERIAL AND METHODS 75 extracted human mandibular premolar teeth were ...

The season of the Nobel awards and the ensuing ceremonials is upon us. As the current laureates prepare to graciously stand in line before the crowned heads of Sweden and Norway, it’s an appropriate moment to reflect on what the prize has come to mean, and whether it still serves a useful purpose in today’s world. Although the Nobel Prizes are held in high esteem by the general public the world...

The purpose of this in vitro study was to evaluate the ability of a silicon-based root canal sealer, compared to zinc oxide and eugenol and an epoxy resin-based sealers, for filling of simulated lateral canals. Thirty extracted single-rooted human teeth were selected, conventional access was made and the working length was established 1 mm from the apical foramen. Three simulated lateral canals...

MATERIAL AND METHODS The aim of this study was evaluate the influence of ultrasonic activation (UA) of AH Plus to improve canal and isthmus filing, and analyse the antimicrobial effect against Enterococcus faecalis within dentinal tubules. Thirty mesial roots of mandibular first molars were selected and divided into 2 groups (n = 15): with and without UA of the sealer. Then the root canals were...

The aim of this study was to evaluate the influence of the sealer placement technique on the quality of root canal filling using Lateral Compaction (LC) or Single Cone (SC). In order to do that, 60 mesial roots of mandibular first molars were prepared and divided into 2 groups (n=30), according to the filling technique: LC and SC. Each group was subdivided into 3 subgroups (n=10), according to ...
