Comparison of the Polymerization Effectiveness Between the Blue phase 20i Curing Light and A Generic Lamp Manufactured in China

Abstract

Polymerization is a process that involves the intermolecular bonding of composite resin by light curing, therefore, it is crucial to have a device that meets characteristics that allow adequate light curing, i.e., optimal curing of the material. The main objective of this paper was to evaluate the effectiveness of polymerization using two light-curing lamps: the Bluephase 20i and a generic Chinese-made lamp. In this paper, a qualitative-quantitative approach was employed, using a descriptive cross-sectional research design. Methodological and systematic procedures were conducted, which included a documentary analysis through an exhaustive literature review of previous studies published in certified academic journals. Articles were selected from 2014 onwards, which addressed the characteristics of the lamps under study. The results obtained revealed that to achieve adequate light curing, the lamp used must have an irradiance equal to or greater than 400 mW/cm², a wavelength ranging from 400 nm to 515 nm, with a minimum penetration action of 2 mm to ensure good depth curing capacity. In addition, it was found that the width of the lamp should be between 9 mm and 11.6 mm to obtain optimal light curing.
