Exploring Mandibular Wisdom Teeth Roots after Coronectomy

by

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

Blueberry extract could help treat periodontitis

by

In an article by Amel Ben Lagha and et al titled “Wild Blueberry (Vaccinium angustifoliumAit.) Polyphenols TargetFusobacterium nucleatumand the Host Inflammatory Response: Potential Innovative Molecules for Treating Periodontal Diseases,” a discussion is made that blueberry extract could be used for treating gum disease (Journal of Agricultural and Food Chemistry, 2015; 63 (31)). Gum disease occurs when bacteria form biofilms or plaques on teeth and the gums become inflamed. In ore severe cases this condition is called periodontitis and requires antibiotic use. By potentially using blueberry extract instead of antibiotics periodontitis could be treated. When gum disease occurs the gums get red and swollen an can bleed easily. If the condition is not treated periodontitis can occur. In order to treat periodontitis dentists scrape off tartar and use antiobitics. Researchers have been exploring other natural ways to treat gum disease. As … Read more

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

Modern Britons Have More Gum Disease than Roman Britons

by

A study of skulls at the Natural History Museum by King’s College London has shown that the Roman British population from 200 to 400 AD appears to have had less gum disease than we have today. Gum disease is also known as periodontitis and has been covered before numerous times on this blog. The researchers examined 303 skulls from a Roman-British burial ground in Dorset for evidence of dental disease. Around 5% of the skulls showed signs of moderate to severe gum disease compared to today’s population which shows around 15 to 30% of adults have gum disease. Many of the Roman-British skulls showed signs of infections and abscesses and around half had caries (cavities). In addition the skulls showed extensive tooth wear from a young age likely due to their diet. The researchers say that Roman-British population did not … Read more

People With Missing Teeth May Not Need Dentures

by

Interesting research from the University of Adelaide questions whether or not all of those people who have dentures really need them. The research was conducted by the University’s Australian Research Center for Population Oral Health in the School of Dentistry and found that people with tooth loss do not have their quality of life interfered with if they still have a certain type and number of teeth left. These patients are considered to have shortened dental arches which enables them to maintain functional use of many teeth. The researchers says there is a cut off point at which tooth loss contributes to loss of quality of life where dentures can be used to improve dentures. However, the researchers feel that dentures are only needed once that cutting off point is reached. The study was based on data of 2,700 Australians. … Read more
