BACKGROUND Marginal integrity of glass ionomer as a restorative material is an important factor for the longevity of the restoration. Class V and cervical abrasions are the most critical and challenging lesions for restorations. The choice of material for restoring class V and cervical abrasions is glass ionomer cement (GIC). Sensitivity to moisture contact during the early setting stages is the drawback of GIC. To overcome the drawback, modifications of glass ionomer cement were made by the addition of chitosan. Chitosan (CH) is a natural linear polysaccharide obtained partially and fully by deacetylated chitin compounds, which are found in crab and shrimp shells, with properties like nontoxicity, biodegradability, bioadhesive, biocompatibility, and biorenewabilty which has led to its use in various fields. Thus, this study intended to evaluate the microleakage of conventional glass ionomer cement and chitosan modified glass ionomer cement using a spectrophotometer. METHODS 60 teeth extracted for orthodontic propose were selected for the study and randomly divided into two groups, class V cavities were prepared on the buccal surface and samples were restored with conventional glass ionomer cement and chitosan modified glass ionomer cement respectively, teeth were immersed in 0.5 % methylene blue for 24 hours and assessed using a spectrophotometer. RESULTS The data were analysed using the Unpaired T - test, and with statistical package for social sciences (SPSS) for Windows, version 25.0 (IBM Corp., Armonk, N.Y., USA). The confidence interval was set at 95 % and values of P < 0.05 were interpreted as statistically significant. CONCLUSIONS The study concluded that the addition of chitosan improves the mechanical properties of conventional glass ionomer cement, and a spectrophotometer can be used as a better evaluation tool in assessing microleakage.

Ionomer Cement

Glass ionomer cement (GIC) is a material that can release fluoride to prevent caries especially in primary teeth. One of the developments of glass ionomer cement in the world of pediatry dentistry is resin-modified glass ionomer cement (RMGIC). The resin-modified glass ionomer cement were still maintaining the clinical advantages oforiginal material, such as fluoride realease, good compatibility and aestehetically. The mechanical properties of rmgic is more higher than gic. These materials have a better adhesion, higher moisture resistance, and a longer shelft life. This paper review aims to know the ability RMGIC as alternative restorative material for primary teeth.

ABSTRACT Objectives The purpose of this in vitro study is to compare the compressive strength (CS) and diametral tensile strength (DTS) of the zirconia-reinforced restorative material (Zirconomer®) with conventional glass ionomers (Fuji 1X) and amalgam. Materials and methods Specimens (n = 120) were fabricated from silver amalgam, reinforced glass ionomer cement (GIC) (glass ionomer, Fuji 1X GC Corp.), and zirconia-reinforced glass ionomer (Zirconomer, Shofu Inc.) for testing the CS and DTS. The results were analyzed using analysis of variance, followed by a Tukey post hoc test. Results Both CS and DTS were found to be significantly higher for the zirconia-reinforced GIC and silver amalgam compared with GIC (p < 0.001). Conclusion A newer class of restorative material like Zirconomer helps to overcome the potential hazard of mercury, but retains the strength and durability of amalgam as well as the sustained high-fluoride release of GICs. Furthermore, long-term studies are required to confirm its use as an alternative to the currently available posterior restorative material.

Dental Applications

Glass ionomer cements and resin-based composites are promising materials in restorative dentistry. However, their limited mechanical properties and the risk of bulk/marginal fracture compromise their lifespan. Intensive research has been conducted to understand and develop new materials that can mimic the functional behavior of the oral cavity. Nanotechnological approaches have emerged to treat oral infections and become a part of scaffolds for tissue regeneration. Carbon nanotubes are promising materials to create multifunctional platforms for dental applications. This review provides a comprehensive survey of and information on the status of this state-of-the-art technology and describes the development of glass ionomers reinforced with carbon nanotubes possessing improved mechanical properties. The applications of carbon nanotubes in drug delivery and tissue engineering for healing infections and lesions of the oral cavity are also described. The review concludes with a summary of the current status and presents a vision of future applications of carbon nanotubes in the practice of dentistry.

This article describes the properties, advances and shortcomings of glass-ionomer cement as a restorative material. The adhesion of glass-ionomer to tooth structure is less technique sensitive than composite resins and its quality increases with time. Therefore glass-ionomer might turn out to the more reliable restorative material in minimal invasive dentistry based on adhesive techniques.

Restorative material is a class of dental materials used for direct filling and fabrication of indirect restoration. NiCr alloy is a restorative material frequently used for dental prostheses due to its properties and economic reasons. In present work beryllium free NiCrMo alloy was developed and studied for dental restoration application. The alloy have unique characteristics of resistance to oxidation and biocompatibility; the requisites for dental prostheses. NiCrMo alloy is found to possess mechanical strength and fabrication properties suitable for dental repairs. In this study the developed alloy was tested for its mechanical properties, biocompatibility and corrosion resistance. An in-vitro biocompatibility study was carried out. No signs of toxicity and no signs of cell growth inhibition, in presence of NiCrMo alloy specimen, were observed. Mechanical properties and corrosion resistance are found in the range that is suitable for dental prostheses and easy fabrication.
