The Early Fluoride Release Pattern of an Aged Glass Ionomer Treated With Fluoride
Abstract
Abstract - The aim of this study was to examine the pattern of early fluoride release from aged glass-ionomer cement after treatment with a 1,000 mg/L NaF solution using hourly and daily time point and to investigate whether surface proï¬le affected release. Composite resin was used as a control. The aged glass-ionomer discs showed a 15 fold greater rate of fluoride release during 1st hour post-treatment, equivalent to the original fluoride release value of the newly mixed material. This rate of release dropped sharply to 3 fold greater than baseline during the 2nd hour. Composite resin showed negligible levels of release. No signiï¬cant differences were found between smooth and rough surfaced groups.
