Bisphenol A and Dental Sealants: The Evidence

September 8, 2010

Researchers at Children’s Hospital in Boston recently conducted a systematic review examining the existence of Bisphenol A in dental materials and assessing potential health risks. This chemical is thought to cause problems with reproduction and development.

Read Summaries of Systematic Reviews

March 25, 2010

Wouldn’t it be nice if you could find all the systematic reviews pertaining to dentistry in one place?  You can!

The American Dental Association (ADA)  Evidence Based Dentistry website includes a database of systematic reviews in oral health. The reviews may be found by searching the site or using the ADA’s drill down topic menu.

Even better, the ADA provides  critical summaries of many of these  systematic reviews.  Critical summaries are brief, concise assessments of a review that are written by ADA Evidence Reviewers.  These reviewers are trained  in the critical appraisal of scientific literature.

Here is a list of the most recently published critical summaries:

Xylitol and Dental Caries

July 31, 2009

Xylitol is a natural sugar alcohol found in some food products and used as a sugar substitute.  Studies strongly suggest that xylitol is non-cariogenic.  That is, xylitol decreases streptococcus mutans levels in plaque and saliva, thus reducing the incidence of dental caries.

Despite these findings, there is little information on the amount of xylitol needed in food products to be effective.  In addition, xylitol is not a clearly labeled ingredient on food packages.

According to the HealthPartners Dental Group and Clinics caries guideline, “xylitol can significantly reduce caries progression if used for five minutes 3-4 times a day after meals and snacks.”  The guideline also states that at least 4 grams of xylitol should be consumed daily.”

In its revised Policy on the use of Xlyitol in Caries Prevention, The American Academy of Pediatric Dentistry stated that they support preventive strategies that use sugar substitutes.  However, the academy recommends further research  and encourages clear labeling of products which contain xylitol.

Cochrane Collaboration Publishes Two Sytematic Reviews for Pediatric Dentistry

Two new systematic reviews pertaining to pediatric dentistry are available in the Cochrane Library.

The first, Dental fillings for the treatment of caries in the primary dentition, compared the outcomes  for restorative materials used to treat caries in the primary dentition in children.  There was insufficient evidence from the included trials to make any recommendations about which filling material to use.

The second review, Extraction of primary teeth for unerupted palatally displaced permanent canine teeth in children, evaluated the effect of extracting the primary maxillary canine on the eruption of the palatally ectopic maxillary permanent canine.  Reviewers concluded that there was  no evidence to support the extraction of the deciduous maxillary canine to facilitate the eruption of the palatally ectopic maxillary permanent canine.

Full text acess to both reviews is available for URMC affiliates.  Select Cochrane Library from the Bibby Library website.

Eating Disorders and Oral Health

February 19, 2009

February 22-28, 2009 is National Eating Disorders Awareness Week.

Physical changes in the mouth are one of the first signs an eating disorder exists. According to the Alliance for Eating Disorders Awareness, up to 89% of bulimics show signs of tooth erosion, and 28% of all bulimic cases are first diagnosed by dental professionals.

Dental practitioners should be knowledgeable about eating disorders and be comfortable discussing their concerns with patients and families.
