The aim of this study was to evaluate and compare the costs for the three orthodontic retention methods using a cost-minimisation analysis (CMA). The cost analysis was based on previous randomised controlled trial data (Dental Elf 22nd Jan 2013).

Another critical summary from American Dental Association Centre for Evidence-based Dentistry – March 2013


This latest critical summary prepared under the auspices of the ADA Center for Evidence Based Dentistry looks at a 2012 meta-analysis by Kühnisch et al that looks at the retention rates of pit and fissure sealants. The results of the meta-analysis suggest that resin-based sealants have the highest retention rates at 5-years. The appraiser notes [read the full story…]
