Restorative Glass Ionomer

Details and patient eligibility

About

The aim of this randomised-controlled, single-blind, split-mouth, and single-centre clinical trial was to evaluate the 2-year clinical performances of a high-viscosity glass ionomer and nanohybrid composite resin in occlusal restorations on mandibular second molar teeth in patients at risk for salivary contamination.

Full description

Occlusal carious lesions on the right and left mandibular second molars of 56 patients (26 females, 30 males) were restored in a split-mouth design. A high-viscosity glass ionomer (Hv-GIC) (Equia, GC) was used to restore the carious lesions in patients in the treatment group, while a nano-hybrid composite resin (GSO) (GrandioSO, Voco) was used for patients in the control group. Clinical evaluations of the restorations were performed at 1-week, 6-month, 1-year, and 2-year follow-up appointments, according to the FDI criteria. Data were analysed using the Friedman's analysis of variance and Mann-Whitney U tests (α=0.05).
