Reoperation in Wisdom Teeth Having Coronectomy

An interesting article titled “What Are the Parameters for Reoperation in Mandibular Third Molars Submitted to Coronectomy? A Systematic Review,” appears in the 2019 edition of the Journal of Oral and Maxillofacial Surgery written by Barcellos et al. The article seeks to identify factors that are associated with needing a reoperation after having a lower wisdom tooth coronectomy. Coronectomy is often suggested to treat wisdom teeth where their is a belief their is a high chance of damage to the inferior alveolar nerve with their removal see for example Do People Know about Coronectomy For Management of Wisdom Teeth? and Coronectomy Five Year Follow Up. Typically such risk is assessed using panoramic radiography and cone-beam computed tomography. In the article the authors implemented a systematic review exploring articles on wisdom teeth coronectomy up until June 2018. A total of 362 studies … Read more

Do People Know about Coronectomy For Management of Wisdom Teeth?

An interesting article titled “Coronectomy: a recognised procedure?” appears in the 2018 edition of Oral Surgery written by Dhanrajani and Smith (vol. 11, pp. 273-281). The article discusses a review of the literature on coronectomy to treat wisdom teeth along with a retrospective study. Coronectomy is often suggested to treat wisdom teeth when there is a high risk of nerve damage and is associated with a low rate of complications, see for example the past posts Care Guidelines for Wisdom Teeth: 2014 Finnish Guidelines, A Study of 185 Coronectomy Procedures of Wisdom Teeth, and Complications Associated with Coronectomy. In the article by Dhanrajani and Smith the authors discuss how the inferior alveolar nerve or lingual nerve can be damaged during wisdom teeth removal and that patients seek to avoid such a complication. Coronectomy is a procedure that removes only the … Read more

Complications Associated with Coronectomy

An interesting article titled “What Are the Types and Frequencies of Complications Associated With Mandibular Third Molar Coronectomy? A Follow-Up Study,” appears in the 2015 Journal of Oral and Maxillofacial Surgery (vol. 73, pp. 1246-1253) and written by Giuseppe Monaco. The article explores the likelyhood of complications occuring with coronectomy procedures. Coronectomy is an alternative surgical procedure to extract wisdom teeth with roots that are close to the mandibular canal. The article describes a research study  to determine whether coronectomy decreased neurologic damage in cases of mandibular third molars in close proximity to the inferior alveolar nerve. The study looked at 94 healthy patients with a mean age of ~30 who had 116 mandibular third molars (wisdom teeth) treated with coronectomy. A total of 28 patients dropped out of the study during the 3 year follow up period. Of the … Read more

Pneumomediastinum After Coronectomy

An interesting article titled “Surgical emphysema and pneumomediastinum after coronectomy” appears in the 2015 British Journal of Oral and Maxillofacial Surgery and written by C. Wong and et al. (vol. 53, pp. 763-764). The article describes a case of emphysema and pneumomediastinum occuring in an otherwise healthy 48 year old women after coronectomy of a lower wisdom tooth. This was determined by a chest x-ray after she presented with swelling and impaired eye opening. No surgery was necessary and after staying in the hospital several hours she was discharged. Around a week later the swelling had resolved. The authors say they do not know of any other cases of pneumomediastinum occuring after coronectomy; however, it is known to occur after wisdom teeth removal. See http://www.teethremoval.com/complications.html where a discussion of this occurs. It appears that an air turbine drill was used in this women’s case and introduced air into the mediastinum … Read more

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
