Root migration pattern after third molar coronectomy: a long-term analysis

Coronectomy was introduced as a treatment for impacted lower third molars at high risk of inferior alveolar nerve damage. Root migration is considered one of the common surgical complications of this procedure. This study aimed to investigate the long-term behaviour of retained root(s) after coronectomy. This was a prospective study, with 3–5 years of follow-up, of patients who underwent lower third molar coronectomy. Panoramic radiographs were taken preoperatively and at 1 week, 6, 12, 24, 36, and 60 months postoperative.
