“…The teeth specimens treated with CPP-ACP with fluoride (Group A) showed the highest remineralising potential compared to the teeth treated with S-PRG Fillers (Group B). In tandem with the current study, Wokamatsu et al (2018) [12] concluded that the application of PRG coat to WSLs is a more conservative approach. PRG barrier acts as an adjunct to a periodic fluoride application, promoting a beneficial remineralisation effect on WSLs [12].…”

Background: Early treatment of white spot lesions is essential to prevent the progression of the lesion. Aim: To evaluate and compare the remineralizing potential of CPP-ACP with fluoride (Casein Phospho Peptide-Amorphous Calcium Phosphate) and S-PRG fillers (Surface Pre reacted glass fillers) using atomic absorption spectroscopy and colorimetric method. Materials and methods: Forty sound human premolars were used in this study. They were divided into two groups (A & B), consisting of 20 samples in each. White spot lesions (WSLs) were established on the window (4x4 mm 2 ) created on the buccal surfaces of the samples. Samples in group A were treated with casein phosphopeptide amorphous calcium phosphate (CPP-ACP) with fluoride, those of group B were treated with S-PRG Fillers. The sample teeth were immersed in a demineralizing solution for 4 days. All the samples were subjected to loss of mineral content (wt %), i.e., calcium, using atomic absorption spectroscopy and phosphorus using the colorimetric method. Results: Statistical analysis was performed using one-way analysis of variance, Tukey's and paired t-tests. Group A exhibited the highest remineralizing potential, followed by Group B. Statistically, a significant difference (p=0.001) was observed between the two groups. Conclusion:There was a significant difference in remineralizing potential of CPP-ACP with fluoride and S-PRG Fillers. CPP-ACP with fluoride appears to be an effective technique in the remineralization of white spot lesions.

“…The varnish containing this filler, in its calcium type (PRG-Ca), prevents demineralization around materials containing this compound [37] . As a varnish, it induces the release of fluoride and, in addition, has the capacity to recharge when in contact with fluoride pastes, varnishes or mouthwashes [38] . As a sealant, it has a higher fluoride recharging property compared to sealants containing GI [39] .…”

Introduction: Giomers are composed of PRG fillers which in turn contain some ions, in addition to fluoride, which are beneficial to enamel so, it could be used for remineralization. Glass ionomer also contains fluoride and has been a commonly used material for many years. Objective: to analyze information about its chemical composition, physical properties, chemical properties and application of S-PRG technology in comparison with glass ionomer. Methodology: articles were searched in PubMed, Science Direct, Springer and EBSCO. Terms such as S-PRG OR GIOMER, S-PRG AND prevention, glass ionomer AND pediatric dentistry were used. Results: S-PRG has a pre-reactive glass ionomer layer containing reactive ions that acts in contact with water and saliva, thus releasing ions that promote remineralization, bacterial control, etc. It has lower setting shrinkage compared to some ionomers and allows remineralization around the restoration and can be used as a restorative material for primary and permanent teeth. Glass ionomer has an acid-base reaction. By bonding glass ionomer filler to resins, it improves their properties, is successful in the presence of secondary caries and is well accepted as a restorative material after selective removal of carious tissue. Conclusion:Both materials have fluoride releasing and recharging capabilities as well as restorative properties. However, giomer has better esthetic advantages. Further studies are required because giomers are relatively new.

“…S-PRG-filled materials have been shown to be effective in the remineralization of enamel in primary teeth and can therefore be considered as a material for caries prevention treatment [45,38] . Some studies have found that it has less long-term success compared to resins, however, it can be used for cervical and occlusal restorations and even in primary teeth [12] , clinical and radiographic success has been reported both at 6 and 12 months in class II cavities in primary molars [46] and even maintain acceptable qualities after 13 years of follow-up [47] .…”
