Objective: The purpose of this study was to determine the intensity light power and integrity active part curing lights Faculty Dentistry Clinic University Cuenca in March-August 2022 term. Lack knowledge light-curing units, leads dentists purchase low-quality equipment, thinking that they all work with same efficiency, compromising long-term success restorations. Therefore, it is important kno...

Background: Many recent studies have focused on the potential hazards of blue light exposure to ocular health. One group with a unique risk is dentists, who use curing lights that emit intense during restorative procedures. During these procedures, dentists often experience brief lights. The purpose present study was explore whether such exposures may an effect vision and health dentists.

the present work reports and discusses the results of a 3d simulation of the injection molding process of a rubber compound that includes the mold flling stage and  material curing, using the computer code is developed in “udf” part of the fluent 6.3 cae software. the data obtained from a rheometer (mdr 2000) is used to characterize the rubber material in order to fnd the cure model parameters ...

We commercialized Reactive Coke Agglomerate (RCA), a cement-bonded pellet to decrease the thermal reserve zone temperature for the reduction of the reducing agent rate of blast furnaces. To achieve a high productivity of supplying RCA to large blast furnaces, a rapid curing process of RCA using steam was investigated. We obtained rapid curing of RCA within 18 h by combining primary curing for 1...

This investigation aims at determining the microhardness value of the hybrid direct/indirect composite resins submitted to conventional light curing and post-cured using two different methods, a light source from a laboratory light curing unit and a conventional oven heating, and the obtained results were compare to an indirect composite resin. A hybrid direct/indirect composite resin (Filtek P...

Pulpal temperature changes induced by modern high powered light emitting diodes (LEDs) are of concern when used to cure composite resins. This study showed an increase in pulp chamber temperature with an increase in power density for all light cure units (LCU) when used to bulk cure composite resin. Amongst the three LEDs tested, the Elipar Freelight-2 recorded the highest temperature changes. ...
