The reason we do what we do, is so that we can to do what we want to do, when we want to do it!

It’s a tongue twister, but working as a team and making informed decisions, will get us there.

Insurance Incentive Level Plans . . . video demo…………………………………………….

This Week’s Dentrix Office Manager’s Blog by Dayna Johnson

Managing basic dental insurance plans can be frustrating, but what about incentive level plans?  Here in the State of Washington we deal with a lot of incentive level plans and it can be tricky to get it all straight.  I have created a video demonstration to help show you how to attach different incentive level plans to each patient.

Product Review – CRT Bacteria by Ivoclar Vivadent!………………………………………………..

CRT bacteria Test for determining mutans streptococci and lactobacilli counts in saliva and plaque.

 High counts of mutans streptococci and/or lactobacilli indicate a high caries risk status. If protective factors cannot take effect, carious lesions will develop. CRT bacteria provides you with fundamental information before any changes in the tooth structure can be detected. As a result, you have the possibility of introducing adequate counter measures at an early stage. The proven biological test CRT bacteria allows you to clearly identify and semi-quantitatively determine cariogenic bacteria.

“The Root of It” Commentary for Sunday July 29, 2012………………………………….

 This past week I have received a number for calls from clients asking how to respond to a recent article referencing a study on dentistry’s use of Bisphenol A and its effect on children. I contacted several manufacturers and they all provide written statements that BPA is not used in the manufacturing process; however, a small trace may develop as a bi-product from manufacturing equipment. The levels reported are almost un-detectable and well below any government regulation. My suggestion is to contact the manufacturer of the composite that you use and request their written statement so that you can assure your patient base that you are providing the highest standard of care. Also, make sure that all of your clinical purchases are from manufacturer authorized distributor so that you can avoid the chance of purchasing counterfeit products. 

Also, as a side note the reports on the news were referencing a study done on less than 550 children over 5 years. Although I have not had the opportunity to read up on the study, a small group can be influenced by environment, cultural life style & educational opportunities. I think a broader study is required before we scare parents from preventive or restorative dental procedures. After all, many of us buy bottled water to avoid the tap. What about the BPA level in the plastic containers, isn’t that where it all started?

From the ADA Archives:

Dental patients may ask about a widely reported article on exposure to bisphenol-A (BPA) from sealants and composite materials, which was published on September 7th in the journal Pediatrics and will appear in the October print edition.1 News coverage on the article has raised several common questions about the relationship between BPA, a synthetic chemical resin, and dental materials. This “Science in the News” provides analysis based on the current body of knowledge on sealants and composites that contain BPA derivatives (monomers derived from BPA).

In recent years, widespread media attention has focused on environmental exposure to BPA in consumer products (e.g., plastic bottles and canned foods), citing public health concerns and persistent debates about BPA’s safety, its reported estrogenic properties, and potential adverse health effects. Of relevance to dentistry, BPA has often been publicized as a chemical that was “found in” or “released from” dental materials, which has generated some misperceptions and inaccurate information about health risks related to potential BPA exposure from dental materials. Many questions have also been raised about the presence of BPA as a starting ingredient in the formation of two monomers that are widely used in resin-based materials: bis-DMA and bis-GMA. 

To read the rest of this article log onto:

In the vast majority of dental materials, bisphenol-A is not used directly in the manufacturing process. Resin-based materials are commonly made with bis-GMA, and research has shown that bis-GMA does not hydrolyze into BPA.2 For these reasons, previous studies have not identified significant amounts of BPA in dental sealants or composites

The American Academy of Pediatrics (AAP):

On September 7, 2010 published a very interesting article online titled, “Bisphenol A and Related Compounds in Dental Materials: A Critical Review,” which takes a look at dental materials, and their BPA content. Certain dental material such as composite (white) fillings and dental sealants may contain BPA. It is not yet known how much BPA is absorbed into the body, but what is known is how BPA is released from the resin. Enzymes from your saliva have been found to release the BPA from resin materials. According to the researchers, the time immediately after the placement of such materials represents the period in which the greatest chance of exposure may occur. The research team did note that dentists may reduce the potential for BPA exposure by using an abrasive, such as pumice, to remove the top liquefied layer, in this case for a dental sealant, and rinse the tooth for 30 seconds immediately after placement of the sealants, to reduce the levels of salivary BPA.

ADA Council on Scientific Affairs Statement:  

CHICAGO (July 2010)—Bisphenol A (BPA) is widely used in the manufacture of many consumer plastic products. Some laboratory testing has suggested that BPA may affect reproduction and development in animals by mimicking the effects of the female hormone estrogen, thereby raising concerns about its safety. To date, these effects have not been observed in humans and are questionable at the exposure levels resulting from consumer products.

The food industry uses BPA when manufacturing the epoxy resins that coat cans and polycarbonate bottles intended to hold foods and beverages. Bisphenol A also is found in some children’s toys, plastic tableware and infant bottles. The release of industrial and household wastes into the environment also exposes humans to BPA. There is also evidence that some dental sealants, and to a lesser extent dental composites, may contribute to very low-level BPA exposure.

BPA can become part of dental composites or sealants in three ways: as a direct ingredient, as a by-product of other ingredients in dental composites or sealants that may have degraded, and as a trace material left-over from the manufacture of other ingredients used in dental composites or sealants.

 As a direct ingredient: ADA research, confirmed by direct communications from dental manufacturers, indicates that BPA is rarely used as a formula ingredient in dental products.
