Two new critical summaries are now available at the ADA-EBD site
The first one is of a 2011 review by Yengopal and Mickenautsh; The aim of the review was to assess whether resin-modified glass-ionomer cement (RM-GIC) offered a significant caries-preventive effect compared with resin-based composite (RBC)?
The appraiser generally considers the review to be well conducted although questioning the decision of studies, which evaluated restorations as well as orthodontic adhesives. All the included studies were prospective studies although follow up period ranged from 4 weeks to 25 months.
The review included 4 studies and did not find a difference between in caries adjacent to RM-GIC and RBCs but the available evidence was limited. A commentary on this review by Pendrys is also available in the Journal of Evidence-based Dental Practice.
The second summary is of a 2010 review by Rogers et al that addresses the question; Does the use of fluoride containing orthodontic adhesives reduce decalcification in patients receiving orthodontic treatment.
The appraiser notes that although a detailed search of 5 databases was carried out and 10 studies included there was significant variation in the studies with each of the studies using a different adhesive. As a result the evidence to support an effect for fluoride containing orthodontic adhesives on decalcification was poor. A commentary on this review by Martinez-Mier is also available in the Journal of Evidence-based Dental Practice.
