Effect of obturation technique using a new bioceramic sealer on the presence of...
SANTOS-JUNIOR,Airton Oliveira; TANOMARU-FILHO,Mário; PINTO,Jáder Camilo; TAVARES,Karina Ines Medina Carita; TORRES,Fernanda Ferrari EstevesAbstract The aim of this study was to evaluate the filling ability of a new ready-to-use calcium silicate-based sealer using thermoplastic or single-cone technique in flattened root canals. Twenty-four flattened distal canals of mandibular molars with a buccolingual diameter 4 or more times larger than the mesiodistal diameter were selected. The root canals were prepared and filled (n = 12), according to the fo...
Influence of voxel size on dentinal microcrack detection by micro-CT after root...
PINTO,Jáder Camilo; COAGUILA-LLERENA,Hernán; TORRES,Fernanda Ferrari Esteves; LUCAS-OLIVEIRA,Éverton; BONAGAMBA,Tito JoséAbstract The aim of this study was to assess the influence of micro-computed tomography (micro-CT) voxel size on dentinal microcrack detection after root canal preparation using rotary heat-treated nickel-titanium files. Curved mesial root canals (n = 24) of mandibular molars were prepared using ProDesign Logic 30/.05 (PDL) or HyFlex EDM 25/.08 (HEDM). The specimens were scanned by micro-CT at 5 μm voxel size b...
Micro-CT evaluation of apical enlargement of molar root canals using rotary or ...
PINTO,Jáder Camilo; PIVOTO-JOÃO,Mariana Mena Barreto; ESPIR,Camila Galetti; RAMOS,Maria Luiza Gioster; GUERREIRO-TANOMARU,Juliane MariaAbstract Objective The aim of this study was to evaluate the root canal preparation and apical enlargement of molar root canals with rotary or reciprocating heat-treated nickel-titanium (NiTi) instruments, by using micro-computed tomography (micro-CT). Methodology Mesial root canals (n=48) of mandibular molars, with a curvature between 20° and 40°, were prepared with ProDesign Logic (PDL) 25.01 and 25.06 in rot...
