Clinical evaluation of glass ionomer with glass hybrid technology versus conventional high viscosity glass ionomer in class I cavities in patients with high caries risk: Randomized controlled trial

Abstract

Aim: Glass ionomer is a well-known name in caries management and control. Meanwhile, the dark side in its history is being limited as an interim restoration inside patient mouth. The recently introduced glass ionomer with glass hybrid technology could be a new breakthrough in its future. The aim of this study was to evaluate the clinical performance of glass hybrid glass ionomer compared to conventional high-viscosity glass ionomer in class I cavities in patients with high caries risk. Materials and Methods: In a split-mouth design, 31 high caries risk patients with class I cavities received randomly two pairs of restorations, either EQUIA Forte (glass ionomer with glass hybrid technology) or EQUIA Fil (conventional high-viscosity glass ionomer); both materials were applied according to manufacturer’s instructions. Restorations were evaluated at baseline (1 week) and after 1 year by two blinded assessors using Federation Dentaire Internationale criteria for assessment of dental restoration measuring (functional properties and biological properties). Results: Chi-square test was used to compare the difference between glass-ionomer restorative materials at the base line and after 1 year. A value of P ≤ 0.05 was considered statistically significant. There was no statistically significant difference between both materials for all tested outcomes with 100% success rate (score 1 or 2). Conclusion: Glass hybrid glass-ionomer restoration has shown clinical performance similar to conventional high-viscosity glass-ionomer restoration in class I cavities in patients with high caries risk after 1 year of clinical service.
