Indications and restorative techniques for glass ionomer cement

Abstract

Introduction: Due to its chemical, mechanical and biological properties, the glass ionomer cements (GIC) consist in one of the most versatile direct restorative materials, with many potential clinical indications, especially in the context of minimally invasive dentistry. Nevertheless, they have some limitations and require the knowledge of their characteristics and procedures of application in order to achieve their maximum potential. Objective: To demonstrate through literature review the main characteristics, indications, limitations and future perspectives for the use of GIC. Literature review: The database, such as Pubmed and Lilacs were used. Additionally, books were also evaluated and included. Conclusion: The GIC is in constant evolution and is one of the materials that are best suited in the context of preventive and conservative dentistry. It has satisfactory properties and versatility. On the other hand, presents inferior properties when compared to other direct restorative materials, requiring caution during its handling.

Glass-ionomer Cements in Restorative Dentistry: A Critical Appraisal

“…If the material is closer to pulp chamber it is desirable to protect it with calcium hydroxide liner. 33 Glass-ionomer cements are highly versatile materials in restorative dentistry with great clinical potential mainly because of their natural adhesion to the tooth and also for their reasonable esthetics. The bonding of GICs to the tooth surface has been shown as a result of a good initial wetting, which reflects the hydrophilic nature of the freshly mixed cements, followed by longterm chemical and mechanical interactions leading to a strong interface.…”

“…The zinc-reinforced GI improved the fluoride release and enhanced the wear resistance, flexural strength and fracture toughness. 33,44 With the introduction of the new generation of GICs, there have been significant improvements to GICs that allow them to be used for routine restorations and provisional restorations. Glass-ionomer cements can be used to successfully restore both permanent and primary teeth based upon these clinical implications.…”

“…The release of fluoride occurs mainly in the first 24 -48 hours, but decreases and stabilizes over time, although it can occur throughout the life of the clinical restoration, with the possible reintroduction of fluoride ions. 32,33 Adhesive Bonding Mechanism…”

Biodegradable polymers for dental tissue engineering and regeneration

“…GICs interfere with subgingival biofilm formation, decreasing the irritation of the periodontal tissues [52]. Examples of commercialized GICs are Fuji IX GP, Ketac N100, Dyract eXtra, and Wave [53,54].…”

Effect of Nano Filler on Microhardness, Diametral Tensile Strength and Compressive Strength of Nano-Filled Glass Ionomer

“…More recently, with the advent of ART (atraumatic restorative technique), there was the need to improve the physical properties of these materials, leading then to high viscosity GICs, with chemical activation. These materials have a greater number of particles with smaller sizes [6].…”
