Introduction. From the variety of direct restorative dental materials, composite resins are considered as having the most esthetic and functional properties. The conservative preparation, esthetic results, good mechanical qualities and surface finishing properties of dental composites, combined with the protective properties of fluoride from glass-ionomers, led to a new generation of dental materials: the giomers. Objective. The purpose is to review the available literature about the giomers, regarding the chemical composition, handling properties and esthetics, adhesion and microleakage, fluoride releasing and protection offered, clinical indications. Method. The search was carried out using ScienceDirect and PubMed databases with the following keywords: giomer, esthetic properties giomers and fluoride releasing giomers. A total of 232 articles were initially selected, with the following inclusion criteria: full text articles, written in English, with topics on the properties and the clinical implications of giomers. Papers presented as abstract were not included. In the next step, review articles, duplicates, and articles in other languages were removed; as a result, a total of 44 sources published between 2004 and 2017 were selected. Results. The selected articles referred to the following aspects about the giomers: chemical composition (8 articles), adhesion and microleakage (10 articles), fluoride releasing and pulp protection (15 articles), clinical indications (6 articles), effects of additional treatments and dietary habits (11 articles).

“…The shrinkage of the giomer (Beautifil II) was lower than Fuji II LC when using low mode [26] . It is important to avoid disinfecting the cavity with chlorhexidine before applying the material [27] or contact with aluminum chloride (in class V cavities) because it increases the space between the material and the tooth [28] . Nevertheless, it has high quality mechanical and optical properties [29] .…”

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.

“…Giomers are a new group of composite materials composed of pre-reacted glass-ionomer fillers in a resin matrix; they have some advantages, including the release of fluoride ions and recharging, similar to glass-ionomers, in conjunction with other properties of composite resins, such as optimal esthetics, polishability, and tissue compatibility [ 10 , 11 ]. A study reported that the use of 15% carbamide peroxide increased the surface roughness of giomer, with no change in its color [ 12 ].…”

Objectives: Considering the increasing use of vital bleaching procedures and the increased application of newly introduced resin-based materials for tooth restoration, this study was designed to evaluate the effect of 15% carbamide peroxide gel on the flexural strength of three resin-based restorative materials. Materials and Methods: Three different types of restorative materials namely Beautifil II giomer, Cention N, and Z250 micro-hybrid composite resin were evaluated in this in vitro, experimental study. Twenty-four bar-shaped specimens were prepared from each restorative material, totaling 72 specimens, and were randomly assigned to two subgroups with and without bleaching procedure (n=12). In the bleaching subgroups, 15% carbamide peroxide gel was applied on the specimen surface 8 h a day for 14 days. The flexural strength of the specimens was then measured. Two-way ANOVA was used to compare the flexural strength of the specimens. Results: There was a significant reduction in the flexural strength of materials following exposure to the bleaching agent (P<0.05). The flexural strength was significantly higher in the groups that did not undergo bleaching. However, the mean flexural strength of the restorative materials was not significantly different (P=0.12). Conclusion: The flexural strength of Beautifil II giomer, Cention N, and Z250 micro-hybrid composite resin could be compromised subsequent to bleaching with 15% carbamide peroxide gel. The three resin-based restorative materials exhibited similar flexural strength values irrespective of the use or no use of 15% carbamide peroxide gel.
