1. Tomographic analysis of the apical third of curved canals after endodontic treatment with different automated systems / Análise tomográfica do terço apical de canais curvos após preparo endodôntico com diferentes sistemas automatizados
This study aimed to evaluate through Beam Computed Tomography Volumetric cone (Cone-Beam), transport and the ability to centralize various automated systems. The mesiobuccal roots of maxillary first molars were divided into four groups (n=10) according to the automated systems used: GI - reciprocating with K-file Flexofile, GII - reciprocating with file NiTi

3. Avaliação da capacidade de limpeza promovida pela instrumentação rotatória associada a uma manobra complementar para o terço apical de canais achatados / Evaluation of the cleaning capacity achieved by rotary instrumentation associated with a complementary maneuver for cleaning of the apical third of flattened canals
The aim of this study was to compare by histological and morphologic analisys the cleaning ability of rotary instrumentation associated to a proposed complemental maneuver for the apical third of flattened root canal. Twenty-four human mandibular incisors, with single root canal and anatomic diameter corresponding to the instrument 20, were distributed in 3
