05). The cavity depth of the sandblasted area increased statistically with an increased sandblasting duration (P0.05) but did not increase with an increase NTD (P0.05). The 95% limits of inter-examiner agreement were narrow. All distance and duration combinations tested caused enamel damage. Sandblasting duration had greater impact on the cavity depth than the NTD. The blasting duration should, therefore, not exceed 2s and the NTD should be held at maximum 2mm to minimize the risk of unintentional spread.
