简要总结
This study was designed to find out the stain removal efficacy and also, to find out the operators and patients opinion when use or receive treatment with both air polishing powders.
详细描述
Using air polishing with sodium bicarbonate powders with grain size 65 µm provides efficacy in the removal of dental stains but it can cause gingival trauma if used towards the gingiva. Since having big size particles is uncomfortable, the current recommendation according to literature is to use a smaller grain size (40 µm) that results in more patient comfort. However, the efficacy of small grain size on stain removal has not been studied adequately. This study aimed to compare the stain removal efficacy between sodium bicarbonate powders with grain size 65 µm and 40 µm and also to evaluate patient's acceptance after treatment and operator's opinion after using both air polishing powders.

盲法说明
Each group received treatment through a different operator (one operator per one group). Each patient was randomized using sealed envelopes according to treatment side (right or left) using powder grain size 65 µm or 40 µm. The patients and operators were blinded from the type of the powder.
