 Normally, the permanent mandibular first molar has two roots, one mesial and one distal root

 Rarely, an additional third root is seen, which is found distolingually, called the radix entomolaris (Figure 1.16)

 Occasionally, supernumerary roots may be detected in mandibular third molars, mandibular canines and premolars

 No treatment is required

 Detection is critical for endodontic treatment
