Abstract

Some topical fluorides cause surface changes in dental materials. The purpose of this study was to compare the effects of a topical acidulated phosphate sodium fluoride (1.23% APF) foam with the effects of other topical fluorides on the surface of veneer porcelain. Forty porcelain specimens (Ceramco) were placed into eight groups (N = 5). Four groups were immersed in either 1.23% APF foam, 1.23% APF gel, 2.0% sodium fluoride (NaF) gel, or water (reference) for 1 min. The other four groups were immersed in one of the above agents for four 1-min immersions. The surface topography of two scanning electron micrographs of each specimen was scored visually by two raters and by computer digital analysis (CDA). Inter-rater reliability was r = 0.67 (intraclass correlation coefficient). There were no significant differences in the mean visual scores or CDA scores among any of the groups immersed for 1 min. Porcelain immersed 4 min in APF gel had significantly greater mean visual scores and CDA scores than the other treatments (P <or = 0.0001; one-way ANOVA and Tukey's Studentized Range Test). The average surface topography scores of veneer porcelain immersed for 1 min in 1.23% APF gel, 2.0% NaF gel, 1.23% APF foam, or water were not significantly different. Significantly greater surface topography scores occurred following 4 min of immersion in 1.23% APF gel than all other agents.
