introduction: application of light transmitting posts to restore greatly damaged endodontically treated teeth has been increased. it is suspected that light intensity decreases as it passes throughout different materials. this can reduce the degree of conversion required for adequate bond strength throughout the length of these posts. the objective of this study was to evaluate the amount of li...

OBJECTIVE To evaluate the effect of a light-transmitting post on the depth of cure of a resin composite. METHODS Acetate resin molds were filled with resin composite in which a light-transmitting post was inserted into the center and photopolymerized to the manufacturer's recommendations. Identical molds without a light-transmitting post were photopolymerized in a similar matter and served as...

the chemical nature of secretion by the stigma and transmitting tissue in datura stramoniumwas studied by light microscopy using sudan black b, coomasie brilliant blue (cbb), toluidine blue,safranin, and pas. the stigmatic secretion reacted positively for lipids. during development, stigmaticcells became separated and intracellular lipids were transferred to intercellular spaces where theygradu...

AIM To measure the light transmission through different esthetic posts and to evaluate the degree of polymerization of dual cure resin cement cured through these posts. MATERIALS AND METHODS The posts were divided into two experimental groups i.e. Group A (D.T. Light post); Group B (D.T. White post) and control i.e. Group C (metal post), each group having 10 samples. Posts of each group were ...
