Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).
