Desta forma, o objetivo do presente estudo foi avaliar a resposta tecidual frente ao uso deste material. Para isso, 57 tubos de polietileno preenchidos com o MTA experimental e o MTA cinza foram implantados em alvéolos de ratos. Como grupo controle, foram implantados tubos vazios. Os animais foram sacrificados após 30, 60 e 90 dias, sendo realizada a análise microscópica dos cortes obtidos e corados com Hematoxilina e Eosina. Foi possível concluir que o MTA fotopolimerizável apresentou uma resposta semelhante ao MTA cinza, caracterizada pela ausência de uma inflamação severa e pela deposição de tecido mineralizado em contato com o material. / The aim of this study was to evaluate the tissue reaction to a Light Cured MTA or MTA Ângelus® gray. It was used 57 animals, which were divided in three groups. In the Control Group, empty tubes were inserted into the rat’s sockets immediately after extraction. In the other groups, the tubes were filled with Light Cured MTA or MTA Ângelus®. After 30, 60 and 90 days after the implantation, the animals were sacrificed and the right hemi-maxilas were removed and processed in laboratory to analyses on light microscopy, with embedding in paraffin, cut with 6μm thickness and stained with HE. It was possible to conclude that Light Cured MTA presented a similar response when compared to MTA Ângelus®, being characterized by a mild inflammatory response and dystrophic calcifications areas. Despite of a favorable healing process obtained with this new experimental MTA, further studies should be conducted to elucidate these material properties and confirm the present results.
