Clinical Performance of Bioactive Restorative Material Versus Glass Hybrid Restorative in Posterior Restorations

Clinical Performance of Bioactive Restorative Material Versus Glass Hybrid Restorative in Posterior Restorations of High Caries Risk Patients: Randomized Clinical Trial

Clinical performance of bioactive restorative material versus glass hybrid restorative in posterior restorations of high caries risk patients will be evaluated over 12 months using Fédération Dentaire Internationale' (FDI) clinical criteria for the evaluation of direct and indirect restorations

Study Overview

• Status: Unknown
• Conditions: Dental Restoration Failure
• Intervention / Treatment: Other: Resin-modified glass ionomer; Other: Bulk-fill glass hybrid restorative

Detailed Description

The application of resin composite has been described as "technique sensitive". Although glass ionomers are inferior to resin composite in esthetics, there are specific clinical situations where glass ionomers are the materials of choice for restoring teeth as patients at risk for caries and with carious lesions due to its ability to release fluoride and to self-adhere to enamel and dentin.

However, Conventional glass ionomer have poor physical and mechanical properties and are more liable to wear when compared to resin composite. The change in formulation of resin modified glass ionomer restorations allowed them to have improved physic-mechanical properties, combined with significant improvement in esthetic properties. Thus, in recent years glass ionomer as direct restorative materials have become more user friendly. Unfortunately, most of glass ionomers are not recommended as definitive final restorations for the permanent dentition in stress bearing areas because they do not have the physical and mechanical properties of amalgam or composite resin.

ACTIVA™ BioACTIVE-RESTORATIVE™ is recently introduced enhanced resin modified glass ionomer, which the manufacturer (Pulpdent Corporation, USA) reports to be the first bioactive dental materials with an ionic resin matrix, a shock-absorbing resin component, and bioactive fillers that mimic physical and chemical properties of natural teeth. They are durable, fracture and wear resistant, chemically bond to teeth, seal against bacterial microleakage, and release and recharge with calcium, phosphate, and more fluoride ions than glass ionomers. Thus, ACTIVA has more release and recharge of calcium, phosphate and fluoride than glass ionomers with the esthetics, strength, and physical properties of composites, combining the best attributes of both materials without compromising either one.

EQUIA® Forte is a fluoride-releasing, bulk-fill system which consists of EQUIA® Forte Fil, a high strength glass hybrid restorative, and EQUIA® Forte Coat, a wear-resistant, self-adhesive, light-cured resin coating. With improved flexural strength, and acid and wear resistance, the manufacturer claims that EQUIA® Forte extends the recommended indications to include stress-bearing Class II restorations.

The clinical performance of these materials regarding functional, esthetic and biological properties is yet to be evaluated. The FDI clinical criteria provide more detailed evaluation criteria and better differentiation between different types of failure; and incorporate objective assessment tools and a clear scoring system than other scoring systems. Thus, this study aims to contribute to providing evidence-based literature concerning current innovative Resin-modified glass ionomer restorations using the most updated and standardized assessment criteria, namely the FDI.
