RESUMO

Fifteen extracted human teeth were used in which after root canal treatment post preparation was made. During this preparation the middle third of the roots was perforated intencionally. These perforations were filled with three different materials: Silver amalgam, Lumicon, N-Richert Cement, associated in five groups (Lumicon; Lumicon Plus Silver Amalgam; N-Rickert Cement; N-Rickert Cement Plus Amalgam; Silver Amalgam). After this, the teeth were prepared for S.E.M. analysis. The photomicrographics were analysed by 20 observators with the purpose to the determine the filling of the material on the borders of the cavity. The best results were achieved with Lumicon Plus Silver Amalgam.
