introduction: microleakage can result in failure of endodontic treatment. an important characteristic of endodontic sealer is sealing ability. the aim of this experimental study was to compare the apical leakage of teeth obturated with gutta-percha and three different sealers (resin- and zinc oxide eugenol-based) with/without smear layer (sl). materials and methods: in this study, 100 single-ro...

PURPOSE To evaluate indocyanine green angiography (ICGA) and fluorescein angiography (FA) in imaging and quantifying corneal neovascularization (CNV). METHODS Patients with CNV were studied using a standardized protocol of color digital photography, FA, and ICGA. Images were graded independently by two observers and assessed for quality, phases of fluorescence, and leakage. Areas of CNV and v...

Objective: To compare the in vitro apical microleakage of teeth sealed with three techniques: lateral condensation, vertical and Obtura II. Methods: A total 75 single-root were divided into five groups: Group 1 - 2 3 II system, 4 positive control, 5 negative control. The roots subjected to leakage through indirect diffusion Chinese ink, diaphonized, observed under a Vasconcellos microscope. Des...

The purpose of this study was to compare root-end sealing using 4-META/MMA-TBB resin with that using conventional retrograde root filling technique, and thereby determine if 4-META/MMA-TBB resin offers long-term prevention against dye leakage from the root canal of human teeth. Thirty-five teeth had the apical 2.5 mm of the root resected. In the Sealing (SB) group, 4-META/MMA-TBB resin was appl...

Gutta-percha (G) and sealer do not resist coronal leakage. In this study, the effect of orifice plugs using dentin-bonding/composite resin(C) or IRM on coronal leakage was evaluated in vivo. Sixty-one premolar roots in three beagle dogs were instrumented and filled with G and AH 26(S), or G alone. The coronal 2 mm was replaced with C or IRM, or left untreated. The access cavities were kept open...

BACKGROUND Microbial contamination of the pulp space is one of the major factors associated with endodontic failure. Thus, in addition to a three dimentional apical filling a coronal seal for root canal fillings has been recommended. AIM The present study was conducted to evaluate and compare the intra-orifice sealing ability of three experimental materials after obturation of the root canal ...
