Objective The preliminary in vitro study was performed to determine the fluoride retention on enamel surface after topical application with 1.23 % acidulated phosphate fluoride (APF) gel. Materials and methods Thirty caries-free human third molars were used in this study. The teeth were cross sectioned at 2 millimeters below cervical line. Five specimens were randomly chosen as a control group. The fluoride content of the enamel surface was measured by using scanning electron microscope and energy dispersive spectroscopy. Other 25 specimens were topically applied with APF gel for 4 minutes and suspended in artificial saliva. Each five randomized specimens were …
