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.
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).

| Surface lustre of dental restorations | Surface lustre of dental restorations were observed by visual examination of two examiners. Restorations were scored 1 to 5 according to FDI criteria (1. Lustre comparable to enamel, 2. Slightly dull, not noticeable from speaking distance, 3.Dull surface but acceptable if covered with film of saliva, 4. Rough surface, cannot be masked by saliva film, simple polishing is not sufficient. Further intervention necessary, 5. Very rough, unacceptable plaque retentive surface.). | Changes of dental restorations regarding surface lustre were observed at 1-week, 6-month, 1-year, and 2-year results were compared between two restorative material and change of material suring the study is observed |
| Staining restoration surface and restoration margin | Surface lustre of dental restorations were observed by visual examination of two examiners. Restorations were scored 1 to 5 according to FDI criteria (1. No surface staining, no marginal staining, 2. Minor surface staining, minor marginal staining easily removable by polishing, 3. oderate surface staining and moderate marginal staining that may also present on other teeth, not esthetically unacceptable, 4. Unacceptable surface staining on the restoration and major intervention necessary for improvement and Pronounced marginal staining; major intervention necessary for improvement, 5. Severe surface staining and/or subsurface staining, generalized or localized, not accessible for intervention and deep marginal staining, not accessible for intervention.). | Changes of dental restorations regarding surface lustre were observed at 1-week, 6-month, 1-year, and 2-year results were compared between two restorative material and change of material suring the study is observed |
| Fracture of material and retention | Fracture of material and retention of dental restorations were observed by visual examination of two examiners. Restorations were scored 1 to 5 according to FDI criteria (1. No fractures / cracks, 2. Small hairline crack. 3. Two or more or larger hairline cracks and/or material chip fracture not affecting the marginal integrity or approximal contact, 4. Material chip fractures which damage marginal quality or, approximal contacts. 5. (Partial or complete) loss of restoration or multiple fractures.). |
