Aim The aim of this in‐vivo study was to assess the incidence of three roots and four root canals in clinical cases of root‐treated mandibular first molars in a Saudi Arabian population. Methodology A clinical study of 251 root‐canal treated permanent mandibular first molars was conducted The teeth were examined clinically and radiographically. Results The results showed that 5.97% of the examined teeth had three roots, 57.76% had four root canals (two mesial and two distal) and 42.3% had three root canals (two mesial and one distal). Conclusions The occurrence of four root canals in the mandibular first molar of a Saudi Arabian subpopulation was high.
