Depth-dependence of Degree of Conversion and Microhardness for Dual-cure and Light-cure Composites
Operative Dentistry, 2019Clinical Relevance New dual-cure bulk-fill composites show promise for uniform degree of conversion and microhardness throughout the entire depth of direct restorations. SUMMARY Objective: The aim of this ...

Degree of conversion of seven visible light‐cured posterior composites
Journal of Oral Rehabilitation, 1988SummaryThe infrared spectra of seven commercially available posterior composite resins were analysed by ratioing the C = C aliphatic peak to the C = C aromatic peak. The degree of conversion ranged from 43–5 to 73–8%. The result was similar to the range previously obtained from unfilled Bis‐GMA based resins and commercial anterior composites.

Degree of polymerization between adjacent visible light-cured composite areas
Dental Materials, 1985Abstract The degree of polymerization between 2 adjacent visible light-cured composite areas was characterized by hardness measurements and scanning electron microscopy. It was observed that minimum of 20 s exposure for 1 mm overlap and 40 s for 0.5 mm overlap, between 2 light-exposed areas, produced optimal hardness.

Study on phenomenological curing model of epoxy resin for prediction of degree of cure
Journal of Thermal Analysis and Calorimetry, 2012Curing course of Huntsman 1564/3486 epoxy resin system was studied under dynamic and isothermal curing conditions by differential scanning calorimetry technique. The autocatalytic cure kinetic model was established to describe the curing behaviour. A new mod- ified phenomenological curing model based on the Olivier's model was proposed to predict the ...

Changes on degree of conversion of dual-cure luting light-cured with blue LED
Laser Physics, 2009The indirect adhesive procedures constitute recently a substantial portion of contemporary esthetic restorative treatments. The resin cements have been used to bond tooth substrate and restorative materials. Due to recently introduction of the self-bonding resin luting cement based on a new monomer, filler and initiation technology has become important

Combining cure depth and cure degree, a new way to fully characterize novel photopolymers
Additive Manufacturing, 2018Abstract Bottom-up stereolithography has become a common lithography-based additive manufacturing technology (L-AMT) to fabricate parts with high feature resolution for biomedical applications. Novel vinyl ester based photopolymers, with their good biocompatibility and biodegradation behavior, showed a promising capacity as bone replacement materials.

Effect of Post-Vulcanization on the Tire Curing Degree
Key Engineering Materials, 2012The optimum curing times for rubbers used at various parts of a tire are measured under different temperatures. The sulfurization reaction activation energies for various kinds of rubbers are obtained based on Arrhenius’ law and the equivalent tire curing time and curing degree are calculated with or without taking post-valcanization effect into ...

Degree of Conversion of Experimental Light-Cured Orthodontic Adhesives
Key Engineering Materials, 2019The objectives of this study were to compare the polymerization of three experimental light-cured orthodontic adhesives by determining their degree of conversion (DOC) and to compare the results with a control (Transbond XT; 3M Unitek, USA). Three formulas of an in-house orthodontic adhesive were divided according to monomer ratio (BisGMA:TEGDMA) into ...

OPTIMIZATION OF CURING TEMPERATURE PATTERNS FOR FRP PLATE WITH UNEVEN DEGREE-OF-CURE DISTRIBUTION
2017Optimization of curing temperature of FRP was conducted when thickness-wise uneven distributions of temperature existed. It was found that the double-step temperature pattern could minimize both molding time and unevenness of degree-of-cure.
