The article presents a study for the evaluation of caries-like lesion formation around glass ionomer restorations placed in the coronal surfaces of extracted human teeth. For this study, forty extracted permanent teeth were chosen and the method of the study has been described. The study revealed histopathological differences among surface zones from the control and experimental groups. It has been concluded that the initiation and progression of secondary caries may be reduced significantly on the placement of glass ionomer restorations. It was found that the lesions in surface enamel that were adjacent to glass ionomer materials were greatly reduced when compared with control lesions.

    The article focuses on the use of glass ionomer-silver cement in restorative dentistry. The cement bonds with the tooth structure and continually releases fluoride, but due to rapid occlusal wear, glass ionomer cement is not suitable to be used in the high-stress-bearing regions of posterior...

    Fluoride is added to many dental restorative materials, including glass-ionomer cements, for the specific purpose of leaching fluoride into the surrounding tissues to provide secondary caries inhibition. During the caries process, an acidic environment attacks the dental tissues as well as the...
