‘Hemi-Section’: A Step-wise Conservative Approach

A 22 year old female patient had excruciating pain and a history of root canal treatment in relation to the left mandibular first molar. Upon clinical and radiographic evaluation; it was found having separated instrument fragments in the mesio-buccal canal of the left mandibular first molar and incomplete root canal treatment. After careful evaluation of the radiographs, root canal treatment was completed for the premolar and the distal half of the left mandibular first molar. It was then followed by a hemi-section with removal of the mesial half of the left mandibular first molar. Hemi-section was completed successfully which was confirmed on nine months follow-up evaluation with an intra oral periapical radiograph.
