Abstract

O objetivo deste estudo foi avaliar as alterações morfológicas do forame apical após o preparo endodôntico de canais com diferentes sistemas rotatórios, empregando-se a patência e alargamento foraminal. Foram selecionadas trinta raízes de dentes humanos extraídos. As amostras foram divididas de forma aleatória em dois grupos (n=15) de acordo com o sistema de instrumentação a ser utilizado. O grupo 1 foram preparadas com instrumento rotatório PathFile 0.19 (Dentsply) e o grupo 2 com instrumento rotatório 25.01 (Easy). Todos os grupos foram preparados com o nível de instrumentação no limite do forame apical. Fotomicrografias foram realizadas em microscopia eletrônica de varredura (MEV), para registro da anatomia foraminal antes da instrumentação, e após a utilização de cada instrumento. Em seguida as 2 micrografias foram sobrepostas e o forame dividido em 4 quadrantes a partir do seu centro para comparação e análise. O grupo 2 apresentou maior desvio quando comparado com o grupo 1 e (p<0.05). No entanto, não houve diferença estatisticamente significante (p>0.05) entre os grupos 1 e 2 quanto ao alargamento foraminal. Nas condições do presente estudo, foi possível observar um menor desvio apical para o grupo no qual foi realizado a instrumentação com a lima PathFile e não houve diferença significante estatisticamente quanto ao alargamento foraminal entre os grupos analisados.
