Abstract

Introduction: The aim of this study, was to determine the internal anatomy of mandibular first permanent molars extracted from patients in the city of Cuenca, using as parameters the number of roots, number and type of canals according to Weine’s classification. Methods: 50 mandibular first permanent molars were obtained from different Health Centers in the city of Cuenca, in which Robertson’s clearing technique was applied. Results: Overall, 96% of examined molars had 2 roots and 92% had 3 canals, Weine’s type III canal was the most common in mesial root in 58% and type I in distal root with 86% of the cases; 4% of the cases showed three roots, having a supernumerary root known as radix entomolaris, which had a type I canal in all cases.
