Role of fluoride on corrodability of dental amalgams. Naguib EA, Abd-el-Rahman HA, Salih SA. Egypt Dent J. 1994 Oct;40(4):909-18 Operative Dentistry Department, Faculty of Oral and Dental Medicine, Cairo University, Egypt. The role of fluoride ions on the corrosion behavior of some commercial dental amalgam in artificial saliva solution at pH level 7.1 was studied by using impedance and potentiodynamic polarization techniques. It was found that, the presence of F- ions in an artificial saliva solution at pH 7.1 increases the corrodability of different types of dental amalgam. Sever pitting corrosion occurred at level of 100 mM F- ions. The formulation of amalgam alloys greatly affect the resistance to pitting corrosion; the resistance of the amalgam to pitting follows the order: Dispersalloy Phasealloy Oralloy Tytin Valiant-pH.D. It is recommended to avoid oral treatment involving high F- ions concentration in the presence of amalgam restorations.

Response:

Jan got any info on canals? (I mean where amalgams have been removed and replaced with composite?) Anth

Canals?? Just root canals. http://www.zip.com.au/~rgammal/RCTframeset.htm http://www.ericdavisdental.com/root_canals.htm http://www.whale.to/d/root2.html http://www.drshankland.com/rootcanal.html http://webpages.charter.net/kyarbrough/rootcanals.htm http://www.dentistry-toothtruth.com/faq.htm http://www.cfsn.com/maz/ http://cnorman.best.vwh.net/blazing/dental.html http://rheumatic.org/teeth.htm http://www.zip.com.au/~rgammal/root_therapies.htm http://zap.intergate.ca/root.html http://www.toothwisdom.net/ http://www.dentistryholistic.com/education.html http://www.hugnet.com/Root_Canals.html http://www.karlloren.com/ultrasound/p25.htm http://www.hallvtox.dircon.co.uk/hallvt.html Root Canals. A tooth has miles of tiny canals running through the root. A dead or root filled tooth will have bacteria in these canals. There is no way of removing the bacteria once they are in there. http://www.toothwisdom.net/ Toxicity from Root Canals The next subject to be discussed are root canals and their possible source of toxicity. Approximately twenty five million Americans undergo root canal therapy every year in an effort to prevent the loss of teeth that have abscessed. The root canal is the left portion of the tooth which houses the vital organs such as the nerve and blood vessels. The dentist endeavors to clean and sterilize this canal and fill it with a sterile, non toxic inert material. This usually renders this tooth serviceable and non painful; however, the entire inner hard core of the tooth is made of dentin which has several million dentinal tubules. These tubules allow the circulation of lymphatic type fluid to circulate from the vital organs of the root canal to the outside of the tooth. This is a viable circulatory phenomenon which has a purpose. It services the periodontal ligament as well as the sensory aspect of the nerve and blood centers in the root canal. If the body chemistry is healthy, the flow of lymphatic fluid is from the root canal to the outside of the tooth. This creates an irrigation for the tooth and usually prevents the accumulation of plaque to form. When the body chemistry is not healthy, then the circulation is from the outside of the tooth to the inner root canal. This allows for no irrigation, but rather an accumulation of plaque to form. There are many more reasons for maintaining the integrity of the circulation in the dentinal tubules. Root canal therapy completely destroys this integrity, and what happens to the non-circulating fluid in these tubules? This fluid as it ages becomes stagnant and becomes a toxic substance. This porous structure now becomes a septic mass emanating poisons into the body. Is this what you want? Mercury amalgams are said to be the caskets of the body. Root canals are said to be the cadavers of the body. I do not recommend root canals for anyone. Each individual has a right to their decisions. Many people simply do not wish to lose a member of their body. I respect this, and I always discuss the consequences. The next area of discussion is whether the root canal filling actually sterilizes the apical end of the tooth. There are so many lateral canals at the root end of the tooth where bacteria can harbor that it is unlikely that a complete aseptic condition exists. This, however, is a debateable subject. Again, the complete acceptance of root canal therapy as a viable substitution for extraction is completely and whole heartedly supported by organized dentistry. You are in violation of the code of ethics if you speak out against root canal therapy. When I was a practicing dentist, I always let the patient make that decision after explaining all pros and cons. FOR IMMEDIATE RELEASE: – Hide quoted text — Show quoted text -California Judge Approves Landmark Warning on Mercury Use in Dentistry. (San Francisco, CA) – For the first time anywhere, dentists will be required to post a warning about the dangers of mercury in their dental fillings. A California Superior court judge finalized the language for the warning to be posted in dentists’ offices here today. The warning will read as follows: Notice to Patients, Proposition 65: Warning on dental amalgams, used in many dental fillings, causes exposure to mercury, a chemical known to the state of California to cause birth defects or other reproductive harm. Root canal treatments and restorations including fillings, crowns and bridges, use chemicals known to the state of California to cause cancer. The U.S. Food and Drug Administration has studied the situation and approved for use all dental restorative materials. Consult your dentist to determine which materials are appropriate for your treatment. The exact language of the warning was argued and then finalized before Superior Court Judge James A. Robertson II between the California Dental Association, the largest constituent organization of the American Dental Association and Attorney Shawn Khorrami (Cor-ahm-mee). The agreement requires its member dentists to warn patients about the toxic dangers of mercury dental fillings and root canals. The agreement also allows non-CDA dentists to opt in to the agreement and post the warning. The warning is the result of a lawsuit filed by The Law Offices of Shawn Khorrami on behalf of As You Sow, a not-for-profit foundation dedicated to advocacy and activism in the public interest. "This is the first admission by organized dentistry that amalgams pose a potential health risk," says Shawn Khorrami, lead attorney. "The only problem is that it’s about 100 years too late." This California consent judgment follows on the heels of recent lawsuits filed in Georgia, Texas, Ohio and Los Angeles, California charging that mercury fillings placed in a woman’s mouth contributed to the autism of her child, as well as lawsuits in Maryland, California, and New York charging the American Dental Association with misrepresenting amalgam dental fillings as "silver." The lawsuits basically allege that such fillings actually contain approximately 50% mercury by weight. They cause continuous, daily exposure to mercury and, thereby pose substantial health risks to certain users. Mercury, a highly toxic substance, is the most widely used substance in dental fillings today. The use of mercury-based thimerosal in vaccines also has been the source of the recent controversy in the Homeland Security legislation. Khorrami filed the lawsuit against Roger Fieldman D.D.S., Inc., the Citadel Dental Group, Inc. dental offices, dental laboratories and private dental schools and training programs with more than nine employees. The suit won the enforcement of Proposition 65, Safe Drinking Water and Toxics Enforcement Act [Health & Safety Code
