简要总结

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).

详细描述

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.

研究组 & 干预措施

Equia Forte, randomly applied

Active Comparator

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.

干预措施: Equia Forte (Other)

G-aenial Posterior, randomly applied

Active Comparator

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.
