The Fluoridation RecordNov.22,2021Anewsletter of East Coast Science News, Belchertown, Massachusetts, USA_____________________________________________________________________________________Biocompatible hydroxyapatite-toothpastes effective against decayAn analysis of clinical trials on the use of hydroxyapatite-containing toothpastes haslead researchers from the University of Toronto and the Dr. Kurt Wolff Company of Germany to conclude that thesesafe,fluoride-free toothpastes are effective inreducing tooth decay.Aware of the reported neurotoxic effects of fluoride on the developing brains of children, the authors, Hardy Limeback, Joachim Enax and Frederic Meyer,examined evidence that toothpastes containing biocompatible (biomimetic)hydroxyapatite (HAP)crystals, also called calcium phosphate hydroxide,instead of fluoride could reduce the risk of tooth decay.Their report, in the current issue of the Canadian Journal of Dental Hygiene,contains the detailed procedures they usedininvestigating all known published reports on the subject as well as an extensive list of the fluoride-free,HAP-containing
toothpastes available.In addition to their concern overfluoride’s safety, the authors suggest that the smaller amounts of fluoridated toothpastes recommended by dentistsfor children, a rice grain-or pea-sized portion,may not be effective.“There is no direct evidence that these smaller amounts of toothpaste can prevent cavities: the“rice-sized smear”may even be ineffective in preventingcaries formation,”they report.Theauthors conclude:“Based on the evidence published to date one canconclude the following:1. Biomimetic HAP particles rebuild tooth mineral.2. HAP reverses and remineralizes early cariouslesions by providing the ions (calcium andphosphate) required for remineralization.3. HAP provides additional calcium and phosphate insaliva and biofilm for improved remineralizationconditions in the oral cavity. Adding calcium andphosphate to biofilm is an important mechanismfor remineralization.4. HAP works differently from fluoride and works atleast as well as fluoride in preventing dental decayin the primary and secondary dentitions.”Regarding concerns about fluoride’s safety they write, “A simple and convenient solution to the problemis to substitute fluoride in toothpastes targeted for youngchildren with an effective and safe anticaries agent.”https://files.cdha.ca/profession/journal/2752.pdf______________________________________________________________________________The Fluoridation Recordis published weekly at Belchertown, Massachusetts by East Coast Science News, P.O.
