Background: Endo-periodontal lesions (EPL) present considerable diagnostic and therapeutic challenges. Hemisection, when appropriately indicated, serves as a conservative alternative to extraction in multirooted teeth. Case Presentation: This report presents two separate cases in which mandibular molars exhibit EPL with localized root damage. Following comprehensive endodontic and periodontal evaluation, the non-salvageable distal root was resected, and the remaining mesial root was preserved. Treatment included nonsurgical root canal therapy, full-thickness flap surgery, debridement, hemisection and socket preservation using demineralized freeze-dried bone allograft (DFDBA), platelet-rich fibrin (PRF), and a collagen membrane. Both cases were rehabilitated with a fixed partial denture. 12-month postoperative follow-up of both cases demonstrated successful clinical and radiographic outcomes, including stable periodontal parameters and restored function. Conclusion: Hemisection remains a viable option for preserving function and natural dentition in selected cases of EPL with localized root damage.

Publication is the lifeblood of research, it allows for knowledge to be shared, scrutinized and built upon, fostering the advancement of human understanding. Knowledge that is not published holds little value as it cannot contribute to the broader scientific community or drive progress. Academics often face constant pressure to publish to advance in their careers, gain professional recognition, access scholarships and grants, and remain competitive. For novice researchers, selecting the right journal for publication is one of the most crucial decisions. This article provides a guide for researchers, highlighting the essential factors to consider when choosing a journal for their work.
