AIM To compare coronal bacterial and India ink leakage in three different obturation techniques with the smear layer having been removed. METHODOLOGY Seventy extracted single-rooted teeth were instrumented to an apical preparation size 7 Profile Series 29 (Tulsa Dental Products, Tulsa, OK, USA). The smear layer was removed and 20 teeth were randomly obturated with lateral compaction, 20 teeth...

Objective: To compare the effect of Maleic acid and Irritrol (combination Chlorhexidine & Ethylenediaminetetraacetic acid) irrigation on sealing ability Biodentine when used as root-end filling material. Material Methods: Thirty single-rooted human premolars were subjected to standardized root canal instrumentation irrigated with 2.5% Sodium Hypochlorite (NaOCl) after each instrument change. Ap...

OBJECTIVE To investigate the apical sealing ability of glass ionomer and resin-based root canal obturation systems in comparison to a conventional vertical compaction of warm guttapercha. METHODS Forty-five extracted human teeth were randomly assigned into 3 groups of 15 each: a resin-based (EndoRez), a glass ionomer-based (Activ GP), and a conventional gutta-percha plus pulp sealer obturatio...

BACKGROUND One ideal property of a root-end filling material is its apical sealing ability. The aim of this in vitro study was to assess bacterial and dye microleakage of white and gray mineral trioxide aggregate (WMTA and GMTA), Portland cement and calcium-enriched mixture (CEM) cement used as root-end filling material, and to assess the agreement between these two test methods. MATERIALS AN...

INTRODUCTION Favorable apical seal of root filling materials is a crucial factor for a successful root canal treatment. The aim of this in vitro study was to compare bacterial and dye microleakage of two root canal filling materials including standard gutta-percha and nanosilver coated gutta-percha, and to evaluate the agreement between results of these two methods. MATERIALS AND METHODS Fift...

UNLABELLED   INTRODUCTION Blood contamination of the canal during preparation can be a major problem in endodontics; this may result in apical microleakage. The aim of this in vitro study was to evaluate the effect of blood on apical microleakage of a resin-based root canal sealer (AH26) and a polymer-based root canal sealer (Epiphany). MATERIALS AND METHODS In this experimental study, 50 d...

The aim of the present in-vitro study was to evaluate and compare the apical microleakage of Retroplast, Ketac-N100 and heat burnished gutta-percha before and after post space preparation using fluid filtration system. A total of 60 freshly extracted human maxillary anterior teeth were decoronated to obtain a uniform length of 15 mm. each. Mean microleakage of all three materials before and aft...

Abstract Introduction Insufficient seal of apex is a significant reason for an endodontist’s disappointment. The materials root-end filling utilized ought to forestall departure possible pollutants into periapical areas. objective this analysis was compare the fixing capacity three materials: white mineral trioxide aggregate (MTA), Portland cement (PC), and Biodentine. This analyzed through tes...
