Fluoride in Water Does Not Lower Intelligence

An interesting article titled “Community Water Fluoridation and Intelligence: Prospective Study in New Zealand,” appears in the 2014 edition of the American Journal of Public Health by Jonathan M. Broadbent and et. al. The researchers set out to explore whether or not having fluoride in water that one drinks when they are young and age effects the developing brain negatively. The researchers followed nearly all aspects of the health and development of around 1,000 people born in Dunedin in southeast New Zealand in 1972-1973, up to age 38. The researchers compared IQs of those who grew up in Dunedin suburbs with and without fluoridated water. Furthermore, if one used fluoride toothpaste and tablets the researchers used this in their analysis. The researchers focused on fluoride expose during the first five years of life as this is a critical period of time … Read more

Differing Views in Medicine and Dentistry Applied to Wisdom Teeth

An interesting article appears in the 2014 version of the Journal of Oral and Maxillofacial Surgery titled “Asymptomatic Third Molars Under Nominalist and Essentialist Lenses,” written by V. Wallace McCarlie and Daniel L. Orr II, pp. 658-659.  The authors define two differente views: 1) essentialism and 2) nominalism and then try to apply them to the management of wisdom teeth. The authors state “Essentialism is the notion that underlying every properly defined disease is an unchanging reality causing illness. Conversely, nominalism is not concerned with underlying causes, but rather with signs and symptoms of illness.” In the article the authors mention a study which says that dentists detect rather than diagnose. The authors later say that detection implies nominalism and diagnosis implies essentialism. The authors give some downsides to both points of view. For example, they say essentialism is less … Read more

Should the NICE Guidelines for Management of Wisdom Teeth (Third Molars) be Reevaulated?

An article titled “Changes in Demographics of Patients Undergoing Third Molar Surgery in a Hospital Setting Between 1994 and 2012 and the Influence of the National Institute for Health and Care Excellence Guidelines,” written by Vahe Petrosyan and Phillip Ameerally appears in the February 2014 issue of the Journal of Oral and Maxillofacial Surgery, pp. 254-258. The article discusses how National Institute for Health and Care Excellence (NICE) and the Scottish Intercollegiate Guidelines Network (SIGN) were published around 2000 recommending against prophylactic removal of wisdom teeth. This led to a reduction in surgeries performed. In the article the authors question whether or not the NICE guidelines on wisdom teeth should be updated. They mentioned a 2009 study which said 27% of previously symptom free wisdom teeth can become symptomatic after 1 year, especially those that are distoangularly impacted. In the … Read more

Periodontal Disease and Cardiovascular Risk

In a post many years ago I discussed Patients With Moderate To Severe Periodontitis Need to Be Evaluated For Cardiovascular Problems. In a new study, periodontal disease has again been looked at as a risk factor for cardiovascular disease. In the study conducted, more than 15,000 patients with chronic coronary heart disease gave information on their dental health with results showing periodontal disease indicators were common. The study included self reported dental health information from the STABILITY trial, a clinical trial with 15,828 participants from 39 countries all with chronic coronary heart disease and a risk of cardiovascular disease.  All study participants had a physical exam and blood work up, and completed a lifestyle questionnaire. They reported their remaining number of teeth and frequency of gum bleeding. The results indicated a high prevalence of tooth loss with 16% reporting having no … Read more
