About

The aim of this clinical trial was to compare the clinical performances of a glass ionomer restorative system with a micro hybrid resin based composite in extended sized class II cavities. A total of 100 class 2 lesions were restored with a glass ionomer restorative system (Equia Forte) or a micro hybrid composite (G-aenial Posterior). Restorations were evaluated at baseline and yearly during 6 years according to the modified-USPHS criteria. Data were analyzed with Cohcran's Q and McNemar's tests (p<0.05).

Full description

Since the introduction of glass ionomers many modifications of these materials have been performed over the years. Compared to other permanent filling materials like resin-based composites, glass ionomers show several advantages, such as the ability to adhere to moist enamel and dentin and anti-cariogenic properties such as the long-term fluoride release. So, it was doubtful that glass ionomers represent a capable counterpart of amalgam or resin-based composites in posterior teeth.

Trial design

50 participants in 2 patient groups

Equia Forte, randomly applied
Active Comparator group
Description:
Placing glass ionomer restorations, the dentin and enamel of cavities were washed, and briefly dried. Equia Forte Fil was injected into the cavity. Isolation was maintained using cotton rolls and a saliva ejector. After the setting time of 2.5 minutes, the restoration was polished wet using high-speed fine diamonds. When the restoration was briefly dried, Equia Forte Coat was applied and photocured for 20 seconds using a photo-curing light.
Treatment:
Other: Equia Forte
G-aenial Posterior, randomly applied
Active Comparator group
Description:
After etching procedure, the enamel and dentin were conditioned with G-aenial adhesive using a microtip applicator, left undisturbed for five to 10 seconds, and then dried thoroughly for five seconds with oil-free air under air pressure, G-aenial posterior composite resin was applied with the incremental technique (2 mm thick layers) and light-cured for 20 seconds. Finally, the restoration was shaped with finishing diamonds and silicon instruments.
Treatment:
Other: G-aenial Posterior
