Primary Mandibular First Molar
Primary mandibular molars have been usually described as having two grooved and divergent roots that flare to accommodate the developing permanent premolars. In the literature, a considerable variation in number and shape of canal systems has been described in this group of teeth. Overall, it may be inferred that the external and internal anatomy of the primary mandibular first molar closely resembles the primary mandibular second molar. Most studies have found either one or two canals in each of the mesial and distal roots.

Materials and methods Mandibular molars presenting Vertucci’s types I and II canal configurations were selected, and four scans using isotropic resolution of 19.5 μm were accomplished per tooth: prior to treatment (S1), after glide path (S2) and after root canal preparation (S3 and S4). A contrast solution (CS) was used to irrigate the canals at stages S2 and S4. The touched and untouched surface areas of the canals, the volume of irrigant-free areas and the percentage volume occupied by the CS were calculated. Density, surface tension and the spread pattern of the CS and 2.5 % NaOCl were also evaluated. Results In the type I mesial root, there was an increase in the percentage volume of free-irrigated areas from S2 to S4 preparation steps, whilst in the distal roots and type II mes...
