Aim: To measure layer thickness of 5 endodontic sealers and evaluate sealer distribution and adaptation of thermafil and sealer within root canals. Material and Methods: 20 single-rooted teeth divided into 5 groups were prepared in the crown-down technique. Smear layer was removed and root canals were obturated with Thermafil and 1 of 5 different endodontic sealers: AH Plus, Tubliseal, Acroseal...

AIM To evaluate the solubility of five different root canal sealers (AH Plus Jet, RealSeal SE, MTA Fillapex, Tubli-Seal, and Acroseal) in chloroform, eucalyptol and Endosolv-E solvents. MATERIALS AND METHODS Ninety root canal sealer samples were prepared and then divided into three groups for immersion in a solvent for 2, 5 or 10 minutes. The mean values of the root canal sealers' dissolution...

statement of problem: the bond strength of root canal sealers to gutta-percha seems to be an important property for maintaining the integrity of the apical seal which can result in reducing apical microleakage. purpose: the purpose of the present study was to compare the tensile bond strengths of four types of root canal sealers to gutta–percha. this study measured the maximum forces needed to ...

Aims: To compare the apical sealing ability of TotalFill BC, AH Plus Jet, and GuttaFlow Bioseal sealers. Materials Methods: Thirty single rooted mandibular premolars were decoronated standardized at 15mm. The specimens chemo- mechanically prepared, randomized into three experimental groups (n =10) according to root canal sealer tested: Jet and, Bioseal. filled using cone technique. decalcified,...

The need for an antimicrobial penetrant-sealer became evident as the problem of flaking paint in food processing plants was explored. Flaking paint can fall into product, a situation which cannot be tolerated. The standards, set by the packing industry, for purity, freshness, and attractiveness preclude any foreign matter in product. Flaking paint as a problem has been with us since paint was f...

The purpose of this study was to compare the surface pH level of four different type sealers after mixing at various time intervals in vitro. After cleaning and shaping root canals in 50 recently extracted, single-rooted human teeth, they were divided into six groups. Each of four groups was obturated with Apexit, N2, Sealapex, and Grossman sealers. The remaining groups served as controls. In g...

Introduction: Growth and proliferation of the remaining microorganisms within the root canals may destroy the surrounding tissue of the root and leads to periapical lesion. Consequently, the complete elimination of microorganisms from the root canal is a n important goal of endodontic therapy. Endodontic sealers do not provide complete seal in root canal system, and micro spaces have always rem...

The concrete has been and at the same time will be most used construction material worldwide. It is exposed to various physical chemical degradation processes that deteriorate its properties shorten service life in applications. As of detrimental effects on come from ambient environment, quality surface plays a key role overall performance. should resistant abrasion, free microcracks open pores...
