Introduction: This study aimed to compare Guttaflow bioseal, MTA-Fillapex, and AH plus with regards their adaptability on dentin surface. Methods: Thirty (n=30) single rooted human teeth were instrumented divided into three groups according the type of sealer used (each n=10). All root canals obturated lateral compaction technique. Roots cut longitudinally evaluated for using scanning electron ...

Objective. The present study assessed the chemical elements in two novel calcium silicate-containing root canal sealers, BioRoot RCS and Well-Root ST, compared to a calcium silicate-containing root canal sealer that has been on the market for several years, MTA Fillapex, and epoxy resin-based sealer AHPlus. Material and Methods. The sealers were mixed and manipulated according to the manufactur...

introduction: the aim of this in vitro study was to evaluate the effect of mta-based sealer (mta fillapex), eugenol-based sealer (dorifill) and an epoxy resin sealer (ah plus) on the bond strength of fiber posts cemented with a self-etch adhesive. materials and methods: the root canals of 72 maxillary incisors were prepared using the step-back technique after removing/cutting off the crowns. th...

introduction: mineral trioxide aggregate (mta) as an alternative material to gutta-percha for obturation of root canal in special cases has several drawbacks. the purpose of this study was to compare the apical sealing ability of a new mta-based sealer versus mta. materials and methods: a total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3 ex...

(AH Plus, Endomethasone N, EndoSequence BC, MTA Fillapex and Pulp Canal Sealer EWT) using a three-dimensional (3D) cell culture model. A conventional bi-dimensional (2D) cell culture model was used as reference technique for comparison. Balb/c 3T3 fibroblasts were cultured in conventional bi-dimensional cell culture and in rat-tail collagen type I three-dimensional cell culture models. Then, bo...

This study investigated the microleakage of two different root canal obturation systems, using the nuclear medicine approach, with sodium pertechnetate Tc. Twenty six single-rooted extracted teeth were selected. The crowns were sectioned to obtain 15 mm long root segments and each tooth was prepared using rotary ProFile instruments. The roots were divided into 2 experimental groups and two cont...

introduction: the aim of this study was to evaluate the retreatability of root canals obturated with gutta-percha (gp) and three different endodontic sealers [iroot sp (bioceramic sealer), mta fillapex (mta-based sealer) and ah-26 (epoxy resin-based sealer)] using the protaper universal retreatment (ptr) system. methods and materials: forty extracted single-rooted human teeth were prepared with...

BACKGROUND The purpose of this study was to compare the sealing ability of MTA Fillapex, Apatite Root Canal Sealer and AH26 sealers. MATERIAL AND METHODS The present in vitro study was carried out on 142 extracted single-rooted human mature teeth. The teeth were randomly divided into three experimental groups (n=44) and two control groups (n=5). Three root canal sealers were MTA Fillapex, Apa...

The aim of this study was to evaluate the effect of an epoxy resin-based (AH-Plus), a zinc oxide eugenol containing (Pulp-Canal-Sealer) and two calcium silicate containing (MTA-Fillapex and BioRoot-RCS) sealers on primary human osteoblasts (hOB) in freshly mixed and set state. All sealers were mixed strictly according to the manufacturers´ instructions and identically samples were produced. In ...

Seventy-five single-rooted teeth diagnosed with asymptomatic necrosis and apical periodontitis were randomly assigned to 3 experimental groups (n=25), according the root canal sealer: MTA Fillapex, CPM Sealer, AH Plus. Calcium hydroxide was employed as intracanal dressing throughout used during endodontic procedure. Classify each patient's discomfort none, slight, moderate, or severe. Pain rate...
