The glass ionomer cements present very good bio compatibility especially due to the presence of Fluor in their composition. The reactivity from the dental pulp to the ionomer cements is also favorable, even in the case of the profound cavities. The metallic ionomer cements are obturation materials that tend to replace the amalgams and were created by adding of metallic alloys to the glass powder for the purpose of improving the mechanic properties. The resistance to abrasion of the glass ionomer cements reinforced with Ag is increased compared to the ionomer cements, being close to that of the composite resins with micro filling, but inferior to the amalgams or composites for the posterior area. All these properties of the metallic glass ionomers recommend their utilization in accomplishing the definitive obturations of the permanent teeth from the lateral area, where the physiognomic aspect is not on the first place and where it is necessary a
material with fast grip. The physical-chemical qualities and the bio compatibility of the glass ionomers reinforced with particles of silver was our premise in their utilization for the obturation of the molars of six
years in children. Copyright K. Earar, A. Porumb, Simona Cavalu et al.

The glass ionomer cements present a very good biocompatibility due, especially, to the presence of fluoride in their composition. This inhibits the microbial infiltration, protecting the adjacent dental structures against the decay injury. Glass ionomer is a real tank of fluoride on the entire period of life of the restoration. The reactivity from the dental pulp to the ionomer cements is favorable, even in the case of the profound cavities. The fluoride release of conventional glass ionomer cements is estimated higher compared with light-curing glass ionomer cements and compomers. Especially in young children the fluoride release may not only help to prevent secondary caries around the filling but may also reduce the risk of caries at the surface of the adjacent tooth.

The properties of the glass ionomers recommend them to be used in the performance of definitive obturations in the young permanent teeth from the lateral area, where the physiognomic aspect is not prioritary and where it is necessary a material with fast grip. Still is recommended to be used with care in the areas of maximum occlusal stress. The physical-chemical qualities, the absence of the secondary decays and the bio compatibility of the glass ionomers reinforced with particles of silver was our premise
in their utilization in the obturation of the molars of six years in children, as an alternative to the composite materials. Copyright K. Earar, A. Porumb, Simona Cavalu et al.
