Coronectomy of mandibular third molars with dental pathology: a prospective cohort study of 121 molars.

Purpose: Coronectomy is a valuable treatment proven safe for non-pathological mandibular third molars with an increased risk of inferior alveolar nerve injury. Coronectomy may also be useful for mandibular third molars with dentigerous cysts and caries, but this is not commonly performed due to the lack of well-designed, evidence-based studies. Here, we aim to investigate the safety of coronectomy for mandibular third molars with caries and dentigerous cysts.

[Geostatics in impacted mandibular third molar surgury].

Exploring the application of minimally invasive techniques in the extraction of impacted mandibular third molar (IMTM), to achieve the treatment goal of "less trauma, short time, fast recovery", remains the focus of dentists. For now, the IMTM are mostly extracted in pieces after removing the crown and root resistance by bone removal and tooth segmentation, using 45°reverse-angle high speed turbine, piezosurgery, chisel or other dynamic system. However, There is a lack of principle-level parsing in different provinces and primary hospitals, while experience is still the main factor in avoiding excessive bone removal in complex IMTM extraction, as well as optimizing the specific position and angle of the parting teeth, finding the fulcrum and designing the best dislocation path when there is root resistance.
