People with Missing Teeth May Have Increased Cardiovascular Events

by

New research has suggested that tooth loss can indicate if a person will have future cardiovascular events, diabetes, and death. The study was conducted at the University of Helsinki in Finland and in collaboration with the National Institute for Health and Welfare. The study used National FINRISK 1997 study data which is a Finnish population-based survey of 8,446 subjects, ages 25 to 75, who filled a comprehensive questionnaire, and participated in clinical examinations. In the study the number of missing teeth was recorded at a baseline and future information regarding health was recorded at a 13 year follow up. It was found that having more than five missing teeth increased the risk for coronary heart disease events and myocardial infarctions by as much as 140 %. If one had more more than nine missing teeth they had an increased risk for diabetes … Read more

A Study of 185 Coronectomy Procedures of Wisdom Teeth

by

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

by

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?

by

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

Measuring Lingual Position of Lower Wisdom Teeth

by

An interesting study titled “Measurement of the Lingual Position of the Lower Third Molar Roots Using Cone-Beam Computed Tomography,” appears in the January 2015 issue of the Journal of Oral and Maxilofacial Surgery (vol. 73, issue 1) and written by Yusuf Emes and et al. The authors set out to use Cone-beam computed tomography (CBCT) to evaluate the proximity of lower wisdom teeth roots to the lingual cortex, which can be used to determine the potential risk of root displacement during lower wisdom teeth removal. The study used CBCT images of 32 impacted lower wisdom teeth of 31 patients (5 men and 26 women). The images were collected for reasons not related to surgery including impacted teeth, dental implants, and cysts of the jaws. An evaluation was performed independently by 2 trained oral and maxillofacial surgeons who were experienced in … Read more
