Abstract

Objective: The aim of this paper is to present the results of a consensus meeting on the threshold property requirements for the clinical use of conventional glass-ionomer cements (GICs) for restorative indications. Methods: Twenty-one experts on GICs evaluated the results of tests on mechanical and optical properties of 18 different brands of restorative GICs: Bioglass R {[}B], Chemfil Rock {[}CR], Equia Forte {[}EF], Gold Label 2 {[}GL2], Gold Label 9 {[}GL9], Glass Ionomer Cement II {[}GI], Ionglass {[}IG], Ion Z {[}IZ], Ionomaster {[}IM], Ionofil Plus {[}IP], Ionostar Plus {[}IS], Ketac Molar Easymix {[}KM], Magic Glass {[}MG], Maxxion R {[}MA], Riva Self Cure {[}R], Vidrion R {[}V], Vitro Fil {[}VF] and Vitro Molar {[}VM]. All experiments were carried out by a team of researchers from Brazil and England following strict protocols, under the same laboratory conditions throughout, and maintaining data integrity. Results: There was consensus on: determining as primary properties of the material: compressive strength, microhardness, acid erosion and fluoride release, and as secondary properties: contrast ratio and translucency parameter, in order to rank the materials. Seven brands were below the thresholds for restorative indications: IZ, IM, IG, MA, VF, B and MG. Conclusions: Based on the primary properties adopted as being essential for restorative indications, the conventional restorative GICs that met the thresholds and could be considered suitable as long-term restorative materials were: EF, GI, GL9, KM, IP, GL2, IS, CR, V, VM and R. A decision-making process to select the best GIC must also include results from clinical trials. Clinical significance: This study provides a ranking of GICs that could be considered suitable as long-term restorative materials based on their main properties. (AU)
