After many years of practicing hygiene, I recently tried a R138 as suggested by DIS for supragingival scaling. In the past, I used a McCall 17/18 for posterior scaling and a U15/30 for anterior scaling. The blade on the DIS R138 is straight enough for anterior teeth and curved enough for posterior. Now I can use 1 scaler vs 2 which means less trips to the bracket table and fewer hand motions. Thank you DIS. Please keep these suggestions coming!
