Background: Complete pulpectomy and elimination of wide range of microorganisms from infected primary root canals is not possible through conventional endodontic procedures. Thus, lesion sterilization and tissue repair (LSTR) therapy employing 3Mix tri-antibiotic paste have been used as an alternative endodontic modality for infected primary teeth. Aim: This study aims to evaluate the root resorption rate of endodontically treated mandibular primary molars with conventional endodontic treatment or LSTR therapy and to compare it with their healthy contralateral teeth. Materials and Methods: Fifty carious first and second primary mandibular molars from 25 healthy children aged 7–10 years were treated with two different endodontic procedures using LSTR Therapy and conventional endodontic treatment. The resorption rate of these teeth with healthy contralateral teeth was compared clinically and radiographically at 3, 6, 12 and 36 months using Chi-square test. Results: At 12 months, clinically, there was no difference in the outcomes of both groups but radiographically, statistically significant difference (P < 0.001) in root resorption between treated teeth and their controls in both the groups was observed. At 36 months, interradicular bone resorption around the crown of succedaneous teeth and their delayed eruption was noted in LSTR group. Conclusions: LSTR therapy could be a viable treatment modality for infected/nonvital primary molars with poor prognosis and intended to be maintained for shorter duration in the oral cavity as natural space maintainers.
