ABSTRACT
The aim of this study was to evaluate periapical repair after root canal filling with different endodontic sealers. Sixty-four root canals from dog´s teeth were filled, divided into 4 groups (n=16). Root canals were instrumented with K-type files and irrigated with 1 percent sodium hypochlorite solution. Root canals were filled in the same session by active lateral condensation of the cones and sealers Intrafill, AH Plus, Roeko Seal and Resilon/Epiphany System. After 90 days, the animals were euthanized and the tissues to be evaluated were processed and stained with hematoxylin and eosin. For histopathological analysis, the following parameters were evaluated inflammatory process, mineralized tissue resorption, and apical mineralized tissue deposition. Histopathological analysis demonstrated that Intrafill had less favorable results in terms of apical and periapical repair, compared to the other sealers (p<0.05). AH Plus, Roeko Seal, and Epiphany sealers had similar and satisfactory results (p>0.05). In conclusion, AH Plus and the materials Roeko Seal and Epiphany are good options for clinical use in Endodontics.
RESUMO
O objetivo deste estudo foi avaliar o reparo periapical após obturação de canal radicular usando os cimentos Roeko Seal e Epiphany. Sessenta e quatro canais radiculares de dentes de cães foram obturados, divididos em 4 grupos (n=16). Os canais radiculares foram instrumentados com limas tipo K e irrigados com solução de hipoclorito de sódio a 1 por cento. Os canais radiculares foram obturados na mesma sessão usando condensação lateral ativa dos cones e os cimentos Grupo I - Intra Fill; Grupo II - AH Plus; Grupo III - Roeko Seal e Grupo IV - Sistema Resilon/Epiphany. Após 90 dias, os animais foram mortos e os tecidos a serem avaliados foram processados e corados por hematoxilina e eosina. Para análise histopatológica, os seguintes parâmetros foram avaliados processo inflamatório, reabsorção dos tecidos mineralizados e deposição de tecido mineralizado apical. A análise histopatológica demonstrou que o Intrafill teve resultados menos favoráveis em relação ao reparo apical e periapical comparado aos outros cimentos (p<0,05). AH Plus, Roeko Seal e Epiphany demonstraram resultados similares e satisfatórios (p>0,05). Conclui-se que o AH Plus e os materiais Roeko Seal e Epiphany são boas opções para uso clínico em endodontia.
