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

The Risk of Future Extraction of Wisdom Teeth

An interesting study titled “What is the Risk of Future Extraction of Asymptomatic Third Molars? A Systematic Review,” written by Gary F. Bouloux and et al., appears in the May 2015 issue of the Journal of Oral and Maxilofacial Surgery (vol. 73, issue 5). The study attempts to determine the annual and cumulative rate of when asymptomatic wisdom teeth become necessary to remove. The authors state that the management of asymptomatic wisdom teeth is controversial and unresolved. They performed a systematic review of past studies using PubMed, Google Scholar, and the Cochrane Central Register of Controlled Trials on retained wisdom teeth. The authors had several criteria necessary for the study to be included in their analysis. The studies were included if they were an English language publication, were a prospective study design, had more than 50 subjects, had recorded the … Read more

Does Not Treating Asymptomatic Wisdom Teeth Cause Harm?

An interesting article appears in the July 2015, British Dental Journal, titled “Revolution vs status quo? Non-intervention strategy of asymptomatic third molars causes harm” written by V. Toedtling and J. M. Yates (vol. 219, no. 1, pp. 11-12.) The article addresses how the Faculty of Dental Surgery of the Royal College of Surgeons of England has asked the National Institute for Health Care Excellence (NICE) to re-assess their guidance on wisdom teeth extractions. This is because the group and doctors feel that there is an increasing amount of distal-cervical caries (cavities) in lower second molar teeth (teeth right next to wisdom teeth) when associated with asymptomatic partially erupted mesial or horizontally impacted lower wisdom teeth (mandibular third molars). The authors say that NICE has been reluctant to re-appraise their 2000 guidance and guidelines on wisdom teeth removal. The authors point … Read more

An Australian perspective of removing or retaining wisdom teeth (third molars)

An article titled “Cost effectiveness modelling of a ‘watchful monitoring strategy’ for impacted third molars vs prophylactic removal under GA: an Australian perspective” appeared in the July 2015, British Dental Journal and written by A.A. Anjrini, E. Kruger, and M. Tennant (issue 219, pp. 19-23). The article discusses the direct and indirect costs associated with removing impacted wisdom teeth in Australia. A news article appearing on the Australian ABC Science (http://www.abc.net.au/science/articles/2015/08/17/4283895.htm) titled “Wisdom teeth: are we removing them more often than needed?” by Anna Salleh and written on August 17, 2015, discusses some of the points made in the journal article. The authors were interested in determining if a watchful waiting monitoring strategy should be used for impacted wisdom teeth or if a prophylactic strategy should be used. They looked at hospitalization data for impacted wisdom teeth removal for 2008 … Read more

Exploring the Risk Factors for Injury To Nerves During Wisdom Teeth Removal

An interesting article titled “Risk Factors for Permanent Injury of Inferior Alveolar and Lingual Nerves During Third Molar Surgery,” appears in The Journal of Oral and Maxillofacial Surgery, vol. 72, issue 12, and written by Edward Nguyen and et al. The article assesses the incidence of and risk factors for permanent neurologic injuries to the inferior alveolar nerve (IAN) or lingual nerve (LN) after wisdom teeth removal. The article states “It has been well documented in the literature that the risk factors for IAN and LN injuries include increasing age, unerupted teeth, deep impaction, distoangular impaction, irregular root morphology, lack of clinician experience, lingual flap and retraction, and radiographic signs of proximity of the third molar to the IAN canal. The main forms of altered sensation that can occur include paraesthesia, anesthesia, or dysesthesia, which may be temporary or permanent. The … Read more
