The purpose of the study is to describe a clinical case of endodontic treatment with guided access in the mesial canals of a calcified lower molar, using for the first time a small diameter drill (0.8 mm). The patient was referred to the clinic for localization and treatment of a calcified canal of the first left lower molar. The patient went to an emergency appointment reporting spontaneous pain, tenderness to percussion, and palpation. Radiological examination demonstrated calcification in root canals and radiolucency periapical. Because of root thinning, guided endodontics was considered the most appropriate treatment approach. However, a drill compatible with the diameter of the canal was used (0.8 mm). The use of an endodontic guide combined with a drill with a reduced diameter (0.8 mm) demonstrated greater safety, predictability, low learning curve, and less wear of the cervical and middle portions of a flattened root of a lower molar.
