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.
