Abstract
Abstract A 2‐year clinical trial was conducted using an adolescent population from a low‐fluoride area to evaluate the anticaries effect of self‐applications of zirconium silicate paste containing 9 % stannous fluoride. Three study groups totaling 464 children, with an initial average age of 12.8 years, completed the study. The control group brushed with a non‐fluoride zirconium silicate paste (Zircate Prophylaxis Paste®) once each year; the first experimental group brushed with zirconium silicate paste containing 9 % stannous fluoride (Zircate Treatment Paste®) once each year; and the second experimental group brushed every 6 months with Zircate Treatment Paste. After 2 years, the DMFT and DMFS increments were virtually identical for the control group and the group that received one application of fluoride paste per year. The group that received two applications of fluoride paste per year had a DMFT increment that was about 24 % less than that of the control group; however, the DMFS increment was only 5 % less. These differences were not statistically significant at the P= 0.05 level.
