2 Most scholars believe that ILTM with pathological symptoms, especially mid-to-high mesial inclination, should be prophylactically removed early. Due to the abnormal position and blocked eruption, ILTM often leads to recurrent wisdom tooth pericoronitis, adjacent tooth caries, lower anterior arch crowding, periodontal defects of adjacent molars, tooth root resorption and even temporomandibular joint disorders. Impacted Lower Third Molar(ILTM), with an incidence of 66–77%, 1 is the most common impacted tooth. This review summarizes the research progress on the influence factors, interventions methods and some limitations of distal periodontal defects of adjacent second molar after extraction of impacted mandibular third molars, with the aim of opening up future directions for studying effects of ILTM extraction on periodontal tissue of the adjacent second molar. At present, several studies have suggested that dentists can reduce the risk of periodontal defects of the second molar after ILTM extraction through preoperative evaluation, reasonable selection of flap design, extraction instruments and suture type, and necessary postoperative interventions. The distal periodontal defects of second molars are affected by many factors, including periodontal conditions, age, impacted type of third molars, and intraoperative operations. Several symptoms may occur after extraction, such as periodontal pocket formation, loss of attachment, alveolar bone loss and even looseness of second molar resulting in extraction. Being adjacent to lower second molars, most impacted lower third molars often lead to distal periodontal defects of adjacent second molars. The extraction of impacted lower third molars (ILTM) is one of the most common procedures in oral-maxillofacial surgery.
