Biofilm determination and removal
PLAQUE
Bioclear dual-color disclosing solution was applied to the thoroughly dry teeth using a brush applicator letting it set followed by rinsing as the newer plaque stains were pink and the plaque older than 24 h and cracks were stained purple, then blasting with (aluminum oxide air–water slurry) aluminum oxide powder with Jeep sandblasting device until the entire biofilm was removed.
