Exploring Mandibular Wisdom Teeth Roots after Coronectomy

Coronectomy involves the removal of part of the mandibular wisdom teeth but retention of the root. It is believed to cause less risk to the inferior alveolar nerve than extraction. An article on this topic titled “Histological evaluation of mandibular third molars roots retrieved after coronectomy,” appears in the 2015 British Journal of Oral and Maxilofacial Surgery and written by Vinod Patel and et. al (vol. 52, pp. 415-419). In the article the authors sought to find out the pulpal and periradicular status of retained roots of mandibular wisdom teeth and histologically evaluated coronectomy roots that were removed because of persistent symptoms. It is possible the roots had become infected. A total of 21 patients (with 26 roots) were included in their study with persistent symptoms after the roots had been retrieved. Of the 26 symptomatic roots, radiographic assessments showed coronectomy had been sufficient in … Read more

A Study of 185 Coronectomy Procedures of Wisdom Teeth

An interesting article titled “Coronectomy of the Mandibular Third Molar: A Retrospective Study of 185 Procedures and the Decision to Repeat the Coronectomy in Cases of Failure,” appears in the April 2015 issue of the Journal of Oral and Maxillofacial Surgery written by Boaz Frenkel and et. al. (vol. 73, issue 4). The article seeks to evaluate the success rate of coronectomy and if failure occurs, retreatment. Coronectomy is an alternative extraction technique of wisdom teeth to prevent inferior alveolar nerve (IAN) injury in cases of root proximity to the IAN or complicated root anatomy of the mandibular wisdom teeth. The technique seeks to extract the crown of the mandibular wisdom teeth and leave the roots intact. Coronectomy is not without risks and complications and things such as infection, dry socket, and pain can occur in addition to healing that … Read more
