Foi estudado o efeito da luz visível azul emitida por um aparelho fotopolimerizador sobre a pele do lábio de coelhos. Os animais foram expostos à luz em períodos variáveis de tempo e de duração de exposição, tendo o mais longo atingido 30 minutos diariamente por 180 dias. Os resultados encontrados mostraram que a exposição à luz do fotopolimerizador nos períodos analisados não determinou alterações morfológicas macro ou microscopicamente nesses animais em comparação com os animais do grupo controle.

It was studied the effect of visible blue light produced by a resin curing light photopolymerization device on the lip skin of rabbits. The animals were exposed to the light for several periods of time being the longest one as much as 180 days, 30 minutes daily. The results did not show harmful effects when the lip skin of treated animals was compared to that obtained from animals of the control group. Thus, based in our results, it was concluded that the rabbit lip skin exposure to the curing light of photopolymerization devices does not produce any deleterious effect in its morphology even after exposition of 30 minutes daily during 180 days.
