Objective: To comparatively evaluate the cytotoxicity of EndoREZ (urethane dimethacrylate based), RoekoSEAL (silicone based) and Kalsogen Plus (ZOE based) sealers on HEK-293 (human embryonic kidney epithelial cells) and Vero (African green monkey kidney epithelial cells) cell lines in vitro. Materials and methods: Sealers EndoREZ, RoekoSEAL and Kalsogen Plus were mixed according to manufacturer...

AIM To compare systematically the sealing ability provided by four endodontic cements: AH Plus, Pulp Canal Sealer EWT, RoekoSeal and GuttaFlow. METHODOLOGY A sample of 100 human mandibular incisors with oval-shaped canals was selected from an initial sampling of two hundred teeth. The root canals in 80 teeth were prepared and filled by the same operator using the cold lateral compaction techn...

OBJECTIVES The aim of the present study was to investigate the effects of root canal sealers on the cytotoxicity of 3T3 fibroblasts during a period of 5 weeks. MATERIAL AND METHODS Fibroblasts (3T3, 1×105 cells per well) were incubated with elutes of fresh specimens from eight root canal sealers (AH Plus, Epiphany, Endomethasone N, EndoREZ, MTA Fillapex, Pulp Canal Sealer EWT, RoekoSeal and S...

The aim of the study was to evaluate the distribution of Roekoseal Automix sealer using three different obturation techniques. Forty-five single-rooted extracted human teeth were prepared in a crown-down manner using ProFile instruments. After instrumentation the specimens were filled using Roekoseal Automix with the cold lateral condensation, Thermafil and Obtura II techniques. Each root was s...

Aim of the study was to evaluate cytotoxicity of five root canal sealers at different intervals of time on HEK-293 (human embryonic kidney epithelial cells) and Vero cells (African green monkey kidney epithelial cells). Endomethasone N, EndoREZ, Acroseal, RoekoSeal and AH Plus were mixed according to manufacturer’s instructions. MTT assay was used to evaluate cytotoxicity of freshly mixed and s...

The aim of this study was to evaluate the physical properties of EndoRez, Diaket, Epiphany, Roekoseal, Fibrefill, GuttaFlow, AHPlus, AH26 to that of a traditional zinc oxide based Kerr PCS sealers. Ten samples of each material were evaluated for flow, radiopacity, solubility and dimensional change tests according to ISO standards 20016876. The findings were statistically analyzed. Radiopacity a...

AIM To evaluate the resistance to ex vivo bacterial leakage over a 40-day period of root canal fillings with five new root canal sealers: RC Sealer, Epiphany, EndoREZ, GuttaFlow and Acroseal, compared with Apexit, AH Plus and RoekoSeal. METHODOLOGY One hundred and forty-four single rooted human teeth were divided randomly into eight test (n = 15) and two control groups (n = 12). The root cana...

Coronal leakage is an important factor affecting the outcome of endodontic therapy. This study evaluated the microbial leakage (ML) and the apical inflammatory response (AIR) in dog's teeth after root canal filling with three endodontic sealers, post preparation and exposure to the oral environment, testing the hypothesis that there is a positive correlation between these two histological param...

The aim of this study was to evaluate the influence of moisture on apical leakage using five different types of sealer. There were 120 single-rooted teeth instrumented to .02/#60 and randomly assigned to 10 experimental groups, one control group (AH Plus, lateral condensation) (n = 10) or positive/negative controls (n = 5). Before obturation teeth were dried thoroughly, followed by recontaminat...

The purpose of this in vitro study was to evaluate two commonly used gutta-percha solvents for their effectiveness in dissolving several types of root canal sealers. Seven different sealers (AH26, AH Plus, Diaket, Roekoseal, Sankin Apatite Root Sealer, Sealapex, and Sultan U/P) were used in this study. After mixing according to the manufacturers' directions, each material was syringed into 30 g...
