Medical Forum / General / Dentistry / July 2007Fluoride Gel
Our dentist suggested to use Fluoride OMNII Gel Just for Kids (http:// www.omniipharma.com/omniigel.asp ) for my child because there were cavities on back primary teeth. We searched on web site and found that some web sites mentioned the gel was used for the place with low fluoride drinking water. We live in Los Angeles Area and already use fluoride tooth paste for my 5-year-old child. Before we finally make decision, we would like to give some advices for the nice dentists here. Because we concern the side effects of too much fluoride. Will Drinking water + toothpaste + the gel be under the safe fluoride level? > Our dentist suggested to use Fluoride OMNII Gel Just for Kids (http:// > www.omniipharma.com/omniigel.asp ) for my child because there were [quoted text clipped - 9 lines] > Will Drinking water + toothpaste + the gel be under the safe fluoride > level? The imponderable here is how much is ingested. My own daughter was not efficient at clearing toothpaste from her mouth (in other words, swallowed much of whatever she put on the brush) until she was at least 4 years old and for this reason I only used a very small amount of toothpaste on her brush. Optimal water fluoridation is 0.6 to 1.0 parts per million. The concentration of fluoride in toothpaste is on the order of 1 part per thousand, so even a little swallowed toothpaste over time can throw off the careful calculation of fluoride in water. This brush-on gel appears to be a few times more concentrated than regular fluoridated toothpaste, but I'd imagine the absolute amount brushed on is pretty small. My impression is that the risk of this is probably lower than using large amounts of fluoridated toothpaste. Whether this is the best product to use is another story. If the decay is on the chewing surfaces of the teeth dental sealants may be more important. If the cavities are on the smooth surfaces some kind of fluoride application is probably a good idea. I don't use take-home gels for children because of the potential for overuse. I apply a fluoride varnish such as Duraphat in the office every few months. It is easy to do, and it eliminates the fear of accidental overdosing. Steve  SignatureMark & Steven Bornfeld DDS http://www.dentaltwins.com Brooklyn, NY 718-258-5001 I just think we already use fluoride toothpaste, don't understand why the dentist still give us the gel. Looks a bit surplus. Or maybe it is different kind of stuff from toothpaste. Speaking about the fluoride ingest, if we brush teeth for children and tell them to spit toothpaste and rinse mouth. Will they still ingest some portion of fluoride? How much fluoride will be left on the teeth? Does the fluoride varnish keep releasing fluoride into the mouth, which is then ingested? Thank you very much, Dr. Steve. > I just think we already use fluoride toothpaste, don't understand why > the dentist still give us the gel. Looks a bit surplus.

As the child becomes more efficient at rinsing, less fluoride will be ingested. The usual recommendation is no more than a pea-sized quantity of toothpaste on the brush should be used. There has to be some ingestion from the varnish too, but here the good thing is that the concentration of fluoride where it is applied is very high, but the total amount of fluoride in the application is very low, since the total volume of varnish used is minuscule. Steve About Fluoride Varnish http://jada.ada.org/cgi/content/full/131/5/589 Excerpts: " Two commercially available fluoride varnishes in the United States have the highest fluoride concentration of any fluoride vehicle (22,600 ppm F-)80 and are intended to be delivered by dental professionals. Despite the rapid setting time of the varnish and the small dosage used, the risk exists that young children will ingest some of the product during placement. In addition, as fluoride is released from the varnishes after treatment, some fluoride will be ingested. " "Ekstrand and associates82 conducted analyses of plasma fluoride concentrations in four children (ages 4, 5, 12 and 14 years) after Duraphat varnish was applied. The amount of varnish applied ranged from 2.3 to 5.0 mg. Peak plasma fluoride concentrations of 3.2 to 6.3 micromolar were found within two hours of treatment, followed by a rapid two-hour decrease and a slower decrease thereafter. These levels were comparable with those found after brushing with a fluoridated toothpaste (mean ? standard deviation, 3.63 ? 0.45 ?mol/L) or after ingesting a 1-mg F- tablet (4.47 ? 0.47 ?mol/L)," "Two cases of contact allergy to Duraphat varnish have been reported: one is a case of dermatitis in a dental assistant's hand, and the other is a case of a stomatitis in a patient.85 These allergies were likely related to the colophony component of the varnish. The manufacturer of Fluor Protector claimed that a short-term burning sensation is a side effect if the varnish comes into contact with the gingival tissue. In product advertisements, the manufacturer of Duraphat claims that the use of varnish in patients with ulcerative gingivitis and stomatitis is contraindicated." *** NYSCOF http://www.orgsites.com/ny/nyscof Fluoridation News Releases http://tinyurl.com/6kqtu Tooth Decay Crises in Fluoridated Areas http://www.fluoridenews.blogspot.com/ Fluoride Action Network http://www.FluorideAction.Net Fluoride Journal http://www.FluorideResearch.Org On Jul 22, 10:42 am, Steven Bornfeld <dentaltwinm...@earthlink.net> wrote: > > I just think we already use fluoride toothpaste, don't understand why > > the dentist still give us the gel.
