Dental Amalgam Mercury Poisoning: Why Is It Still an Issue?

This is a guest post written by Harmon Pearson who is currently pursing a post graduate degree in dental science. He  spends time blogging about his pursuits and writing on dental care. When he is not studying, he enjoys restoring antique pendulum timepieces. How is it that in the 21st century we continue to put a known toxic element—mercury—into our mouths?  The question may seem straightforward, but the answer, curiously, is not.  Mercury remains a primary ingredient in dental amalgam, also known as silver fillings.  Other ingredients include copper, silver, tin, and zinc.  These elements when bound with mercury form what’s typically referred to as a stable compound.  It’s hard and resilient to degradation in the mouth environment making it a seemingly ideal compound for replacing small amounts of decayed or removed tooth material.  Because of this, it’s remained a … Read more

American Dental Association’s New Position on Dental Visits

A few months ago the ADA (American Dental Association) released a press release regarding the frequency that patients should be seeing a dentist. This is located over at http://ada.org/8700.aspx. I meant to comment on this earlier, but didn’t get a chance. In a previous blog post earlier this year, located over at https://blog.teethremoval.com/looking-at-the-concept-of-prevention-in-dentistry/I mentioned an article by retired dentist Jay W. Friedman, DDS, MPH. I also provide a quote from the article where he says that semiannual cleanings are unnecessary in some patients. In the risks of keeping wisdom teeth page, when updated in 2011, I added a section discussing dental examination intervals. This was because I had reviewed National Institute for Health and Care Excellence (note NICE was renamed in early 2013), policy over at https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/215663/dh_126005.pdf which states “The actual interval should be a clinical decision by the dentist … Read more

Potential Risks of Surgery for Wisdom Teeth (Third Molars)

M. Anthony Pogrel in his article “What Are the Risks of Operative Intervention?” in the Journal of Oral and Maxilofacial Surgery vol. 70, pp. 33-36, 2012, suppl. 1, goes into complications associated with removing impacted wisdom teeth (third molars). I have previously explored this topic in detail over at http://www.teethremoval.com/complications.html. Although I did a poor job of distinguishing actual complications from negligence. In the article, Pogrel describes how studies have indicated that around 10% (1 in 10) of people undergoing removal of third molars may suffer from a complication. However, most of these complications are mild and will completely resolve in time. Pogrel states “Complications from M3 removal can be divided into 2 groups: those that are short-lived and self limiting, including bleeding, inflammatory complications such as surgical site infection and alveolar osteitis, or “dry socket,” drug reactions, displaced crowns … Read more

Senate Report Calls for Removing Deceptive Corporate Dentistry Entities From Medicaid

Previously I have written an article titled Fraud and Abuse in Medicaid Clinics where a discussion was made that currently dentists have large amounts of debt when they graduate from school. This leads to them having to face potentially hard and difficult choices to pay their bills as they essentially become indentured servants. Recently Senators Charles Grassley (R-IA) and Max Baucus (D-MT) published a 1517 page report in June 2013, titled “JOINT STAFF REPORT ON THE CORPORATE PRACTICE OF DENTISTRY IN THE MEDICAID PROGRAM.” This report is a very large PDF file (143 MB) and is available for download over at http://www.finance.senate.gov/library/prints/.  Don’t be intimidated by the size of the report though as it really is a bit over 30 pages with the rest of the 1400+ pages serving as an appendix. Hence, it is very readable. The report talks … Read more

Association Between Partially Erupted Mandibular Third Molar and Caries in Distal Second Molar

An interesting article titled “Association between the presence of a partially erupted mandibular third molar and the existence of caries in the distal of the second molars,” appears in the International Journal of Oral and Maxilofacial Surgery by S. G. M. Falci and et. al. (October 2012, pp. 1270-1274). The article mentions how previous studies have shown that caries on the mandibular second molar due to the presence of partially erupted third molars has varied between 7% and 32%. The article criticizes prior work where studies based their prevalence data on panoramic radiographs which is not as good as periapical radiographs when diagnosing caries. The authors state “The lack of sample characterization, the absence of sample calculation, the deficient or inadequate statistical analysis and the absence of a description of the eligibility criteria, discredits the scientific evidence of these previous … Read more
