Hemisection of teeth with questionable prognosis. Report of a case with seven-year results

This case reports the long-term effects of hemisection of teeth with questionable prognosis. The outcome in a 34-year-old male patient with mobile teeth in the lower left posterior sextant is reported. Removal of the mesial root of the mandibular first molar and the distal root of the mandibular second molar was done. The final restoration was performed after using a provisional restoration for three months. The final restoration functioned well without detectable mobility or any noticeable bone loss for up to seven years. Within the limits of this report, the hemisection of molars with questionable prognosis can maintain the teeth without detectable bone loss for a long-term period, provided that the patient has optimal oral hygiene.
