Glass ionomer cements: chemistry of erosion.

abstract：:Minimizing patient exposure while maintaining a diagnostically acceptable radiograph is a major goal in diagnostic radiography. Rare-earth filters may be the means to achieve this goal due to their "band-pass effect". The purpose of this study was to examine the image contrast effects and exposure reductions for vario...
