What is Increase of Enamel Fluoride Retention by Low Fluence Argon Laser in Vivo about?

## Abstract ## Background and Objectives The aim of this in vivo study was to investigate if argon laser irradiation of enamel can increase the retention of fluoride. ## Study Design/Materials and Methods Ninety‐eight teeth in 12 patients were randomly divided into three groups: (1) EF group: 40 teeth were only treated by fluoride gel (application for 5 minutes followed by 1 minute rinsing with distilled water). (2) EFL group: 40 teeth were treated the same way as in the EF group but they were lased after fluoridation. (3) E group of 18 teeth were kept without any treatment and considered as reference. In order to quantify the fluoride content in the enamel samples, the teeth were analyzed by proton beam delivered by a tandem accelerator (PIγE, particle induced gamma‐ray emission). The fluoride content of enamel surface is not homogeneous. Therefore, it is necessary to analyze the same enamel area after each treatment. Each tooth was maintained in a fixed tooth holder which was designed to analyze the tooth enamel surface at the same place (1 mm^2^ and around 20 μm in depth) after various treatments. A low energy density of argon laser beam was used: 10.74 J/cm^2^, 30 seconds of ir
