Effect of curing modes of dual-curing luting systems and root regions on retention of translucent fiber posts in root canals
(Journal of Adhesive Dentistry, 2008)
Purpose: To evaluate the effect of different curing modes of dual-curing luting systems and root regions on the pushout strength of fiber posts to intraradicular dentin. Materials and Methods: Forty-two extracted premolars ...
Evaluation of the adhesion of fiber posts cemented using different adhesive approaches
(Wiley-Blackwell, Malden, 2008)
The aim of this study was to investigate the adhesion of fiber posts cemented with luting agents that utilize three currently available adhesive approaches: etch-and-rinse, self-etch, and self-adhesive. Forty-two intact ...
Morphological evaluation of 2-and 1-step self-etching system interfaces with dentin
(Operative Dentistry Inc, Indianapolis, 2006)
This in vitro study evaluated the resin-dentin interface formed by two 2-step and two 1-step self-etching adhesive systems under SEM. Class V cavities (4 x 2.5 x 1.5 mm) were prepared on the buccal surfaces of 25 extracted ...
Characterization of antigen-presenting cells in human apical periodontitis lesions by flow cytometry and immunocytochemistry
(Wiley, Hoboken, 2006)
Aim To analyse phenotypic characteristics of antigen-presenting cells (APC), isolated from human periapical lesions by flow cytometry and immunocytochemistry. Methodology Sixteen periapical lesions were digested for 15 min ...
Microtensile vs Microshear Bond Strength of All-in-One Adhesives to Unground Enamel
(Quintessence Publishing Co Inc, Hanover Park, 2010)
Purpose To determine the bond strength to unground enamel of all in one adhesives in comparison with an etch and rinse system and to compare the reliability of microtensile and microshear methods in providing such measurements ...
Micro-Raman Assessment of the Ratio of Carbon-Carbon Double Bonds of Two Adhesive Systems Cured with LED or Halogen Light-curing Units
(Quintessence Publishing Co Inc, Hanover Park, 2010)
Purpose The purpose of the study was to compare the ratio of carbon carbon double bonds (RDB) of two adhesive systems cured by five different light curing units (LCUs) using micro Raman spectroscopy Materials and Methods ...
Anatomical study of the pterygopalatine fossa pertinent to the maxillary nerve block at the foramen rotundum
(Churchill Livingstone, Edinburgh, 2010)
The anatomy of the pterygopalatine fossa pertinent to the technique of maxillary nerve block at the foramen rotundum was investigated and the ability of inexperienced surgeons to apply the required angles of the injection ...
