Total 30 teeth in each group were included. Preoperatively shade was checked with VITA classical A1-D4® shade guide. The mixture (hydrochloric acid pumice compound) was applied 10 times or more during the same session. Total treatment time was around 30 minutes. Every patient received entire microabrasion treatment. At the end of the treatment, neutral sodium fluoride gel was applied. Then change in shade was checked again with VITA classical A1-D4® shade guide.

It is a non-restorative, conservative treatment that works both chemically and mechanically to remove up to 0.2 mm of affected enamel per application. Pumice either mixed with 18% hydrochloric acid or 5.25% sodium hypochlorite was used to remove fluorosis stains.

Tooth shade was recorded at the baseline with the help of VITA classical A1-D4® shade guide. The arrangement of the shades in the VITA classical family of shades is as follows: A1 - A4 (reddish-brownish), B1 - B4 (reddish-yellowish), C1 - C4 (greyish shades), D2 - D4 (reddish-grey).Determination of shade was done under daylight. Closest shade was selected from the shade tab. Effectiveness was marked positive if there was atleast one change in shade from the baseline just after the procedure to shade group from A1-D4. Effectiveness was marked negative if there is no change in shade from the baseline.
