Uncompleted polymerization and cytotoxicity of dental restorative materials as potential health risk factors

Annals of Agricultural and Environmental Medicine, 2017
Introduction Composite materials used in dentistry indicate adverse biological effects in laboratory conditions. One reason for this activity is incomplete conversion of their polymer matrix, favoring chemical instability and release of biologically ...

Cytotoxicity and Degree of Conversion of Orthodontic Adhesives

The Angle Orthodontist, 2009
Abstract Objectives: To test the hypothesis that there is no difference in the cytotoxicity related to the modes of polymerization of five commercially available orthodontic bonding resins, with and without an oxygen-inhibited layer (OIL), and to evaluate the degree of conversion (DC) of these resins and correlate this to ...

Influence of fiber-post translucency on the degree of conversion of a dual-cured resin cement [PDF]

, 2015
This study evaluated the degree of conversion of one dual-cured resin cement when used to lute fiber posts with different translucencies. To measure the degree of conversion, polyvinylsiloxane molds were prepared to simulate root canals.
