Effect of Acid Etching on Long-term Microleakage of Nano Ionomer Restorations in Burand Laser-prepared Cavities in Primary Teeth.

PURPOSE The purpose of this study was to evaluate the effect of etching on marginal sealing of nanofilled resin-modified glass ionomer restorations in Class V cavities in primary teeth prepared with an Er, Cr:YSGG laser compared to bur preparation. METHODS Standard Class V cavities were prepared on the buccal surfaces of 56 extracted primary canines that… CONTINUE READING
