Abstract

Objetivo: Este estudo teve como objetivo avaliar a irradiância (mW/cm²), o espectro de emissão (mW/nm), a exposição radiante (J/cm²), o perfil do feixe e a profundidade de cura de uma resina composta fotopolimerizada utilizando diferentes unidades de fotopolimerização por LED (LCUs) de baixo custo. Materiais e Métodos: Foram testados os seguintes dispositivos: Dental Wireless; LY-A180; LY-B200. As unidades VALO (polionda) e Elipar DeepCure-L (monoonada) foram utilizadas como grupos controle. A irradiância, o espectro de emissão e a exposição radiante foram avaliados utilizando o MARC Resin Calibrator. O teste de microdureza Knoop avaliou a profundidade de cura e o módulo elástico. Os dados de profundidade de cura foram analisados pelos testes de Shapiro–Wilk, Levene, ANOVA, Tukey HSD (α = 0,05) e análise de regressão linear múltipla. Resultados: VALO e Elipar DeepCure-L apresentaram uma saída radiante homogênea. A ANOVA mostrou que as LCUs e a profundidade da restauração (p < 0,001) foram significativas, mas a interação não foi significativa. A regressão linear múltipla mostrou relação significativa entre o módulo elástico, a irradiância e a profundidade da restauração (p = 0,350). Conclusões: Os testes de profundidade de cura demonstraram que as LCUs de menor custo avaliadas apresentaram resultados satisfatórios; entretanto, quando todas as variáveis foram comparadas, elas apresentaram desempenho inferior em relação às LCUs utilizadas como controle.
