[Clinical research of mandibular embedded third molars extraction by root dislocation first method resulting in external root absorption of adjacent teeth].

Purpose: To evaluate the impact of impacted lower third molar(ILTM) extraction by root dislocation first method on bone formation in the distal middle of the second molar(M2M), pulp status and external root resorption (ERR).

Methods: A total of 64 patients who underwent ILTM extraction in the First Affiliated Hospital of Xinjiang Medical University from January 2023 to October 2023 were selected. Among them, 32 patients underwent root first removal of ILTM (experimental group), and 32 patients underwent crown first removal of ILTM (control group).
