Abstract

AIM: To assess the effect of the application of fluoride gels on the acid resistance of occlusal enamel in primary molars. STUDY DESIGN: Forty-five primary second molars were randomly assigned to three groups: a) control (pH-cycling); b) 2% NaF gel/pH-cycling; and c) 1.23% APF gel/pH-cycling. METHODS: Specimens were longitudinally sectioned in the buccal-lingual direction and used for cross-sectional microhardness testing. Knoop hardness values were converted into vol.% mineral and mineral loss (ΔZ) was then calculated. STSTISTICS: The response variables were vol.% mineral and ΔZ. Data were tested using parametric tests at a significance level of 5%. RESULTS: No statistically significant differences were found between groups regarding vol.% mineral or ΔZ. CONCLUSIONS: A single application of a high concentration fluoride compound does not promote greater resistance to demineralisation in enamel pits and fissures, regardless of the product used.
