The flexural resistence is one of the most used test in researchs of mechanical characterization of resin composites for dental restoration. ISO 4049 photopolymerization technique performed static application stages of light tip. To polymerize the entire area of the specimen some areas must receive extra...
Introduction: the use of light emitting diodes (LED) in domestic and public vias have increased in the last 20 years. In addition, the LED light has been used as a light source for medical applications. Objective: since humans are increasingly exposed to LEDs, there is an urgency to investigate the poss...
Aim: Resin modified glass ionomer (RMGI) is class of material that can be used as sealant for preventing and arresting the progression of caries in pits and fissures. As these are hybrid materials, their properties can be affected by factors related to the polymerization process. ...
Aim: The present study aimed to asses enamel microhardness after office bleaching with diode laser and LED light compared to the conventional bleaching procedure. Methods: Thirty-nine human premolar teeth were collected and randomly divided into three groups regarding of the bleaching techn...
O objetivo deste estudo foi avaliar in vitro a influência de um novo dispositivo fotopolimerização e pino de fibra de vidro nas propriedades mecânicas, físicoquímicas e adesão dos cimentos resinosos. Foram utilizados oitenta dentes bovinos, submetidos ao tratamento endodôntico, distribuídos em 5...
O presente estudo teve por objetivo avaliar a resistência à flexão de um pino experimental de fibra de vidro vazado, e a resistência adesiva entre este pino experimental à dentina radicular, associando a utilização de um dispositivo iluminador em fibra óptica, sob o processo de envelhecimento, al...
Abstract
The objective of the present study was to evaluate the effect of irradiance and radiant exposure on the chemical-mechanical properties of a resin composite. A micro-hybrid resin composite (Clearfil AP-X, Kuraray) was investigated under two different irradiances: low (300 mW/cm2) and high (800 mW...
Objective: To determine the effect of the restorative technique, material’s opacity and the selected light sources on the curing potential (CP) in deep cavities. Material and Methods: The radiant exitance (mW/cm2) of two light curing units (Bluephase G2 and Radii-Cal) was determined at 0...
Objetivo: Várias fontes de luz têm sido utilizadas desde que os materiais fotoativados foram introduzidos na odontologia. Diodos emissores de luz (LEDs) se popularizaram como a principal opção para a polimerização dos materiais restauradores. O objetivo nessa revisão da literatura foi avaliar a in...
Abstract The objective of this study was to evaluate the effect of the exposure reciprocity law of a multi-wave light-emitting diode (LED) on the light transmittance (LT), depth of cure (DOC) and degree of conversion in-depth (DC) of a bulk fill composite. A bulk fill composite (EvoCeram® bulk fill, Ivo...
