| Outline of Final Research Achievements |
The aim of this study was to assess the effect of chewing gums containing POs-Ca and fluoride on natural WSL remineralization in comparison with POs-Ca or placebo (control) chewing gums, in double- blind, randomized, controlled trial. The subjects were randomly divided into three groups and chewed two slabs of each gum three times every day. Each subject followed this regimen for 3 months and attended a monthly review appointment. WSL was assessed using ICDAS criteria and optical boundary depth (BD) recovery rate as a measure of lesion depth by OCT system at a monthly review. This double-blind, randomized, controlled trial study highlights the importance of calcium and fluoride ion bioavailability in the reinforcement of demineralized enamel while the recovery potential of natural WSL was variable among the cases studied in the course of consuming the POs-Ca F chewing gum.
