Evaluation of Irradiance Issued by Different Modes of Photoactivation with and without the use of Luminous Bridge
Journal Title: Medical Journal of Clinical Trials & Case Studies - Year 2018, Vol 2, Issue 4
Abstract
Introduction: The process of photoactivation of the resinous materials begins when the blue light penetrates the photosensitive agent (photoinitiator). In order to attenuate the generation of stresses during the polymerization process, some studies have used different photoactivation approaches, such as low intensity in continuous light, high intensity in continuous light, photoactivation in steps (Soft-Start) and High intensity in High light. Goals: To compare the irradiance emitted by a single device in relation to the methods of photoactivation with and without the use of the transparent tip. Methods: The study was the photopolymerizer from the Dental Clinic of FCMS/SUPREMA, in one level (n = 8) – DABI ATLANTE DB 686 device and two photoactivation modes: Soft - Start and High, with and without the use of the tip. The response variable was the values of irradiance emitted after the tests with the two types of photoactivation with and without use of tip, through the measurement with radiometer Hilux LED MAX. Results: Mean values of irradiance were significantly higher when high photoactivation mode was used (p <0.05) and when no tip was used (p <0.05). Conclusion: From the results found in this study, it can be concluded that the high method presented higher values of irradiance when compared to the soft-start method.
