Effect of various curing lights on the degree of cure of orthodontic adhesives
American Journal of Orthodontics and Dentofacial Orthopedics, 2007 The purpose of this study was to compare the percentage degree of cure (%DC) of orthodontic adhesive resins irradiated with 3 types of light sources of various intensities: plasma arc, halogen, and light-emitting diode (LED).Twenty maxillary incisor stainless steel brackets (0.018-in slot) were divided into 4 groups of 5 brackets each.

Degree of double bond conversion in light-cured composites
Dental Materials, 1987 The curing pattern of five commercial light-cured composites was investigated. Micro-ATR infrared spectroscopy was used to evaluate the degree of cure as a function of distance from the exposed surface and curing time. KHN measurements were also obtained for each depth to relate the hardness pattern to the degree of conversion.

Evaluation of in-situ shrinkage and expansion properties of polymer composite materials for adhesive anchor systems by a novel approach based on digital image correlation [PDF]
, 2019 The curing reaction of thermosetting resins is associated with chemical shrinkage which is overlapped with thermal expansion as a result of the exothermal enthalpy. Final material properties of the polymer are determined by this critical process.
