The aim of this in vivo study was to assess the prevalence of four root canals in root-treated mandibular first molars in Libyan population. One eighty-five root canal treated permanent mandibular first molars was selected. The teeth were examined clinically and radio graphically. The results showed that 73.0% of the examined teeth had three root canals (two mesial and one distal), 26.5% had four root canals (two mesial and two distal) and 0.5% had five root canals (three mesial and two distal). Most of teeth had two roots (2.16%), except three teeth of males (3.16%) had three roots and one tooth of female had three roots (1.11%). Therefore, the conclusion is that the prevalence of four root canals in mandibular first molar is greater, almost one quarter in this sample of Libyan population.
