Summary

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 class I and class II cavities. A total of 140 (80 class I and 60 class II) lesions in 59 patients were restored with a glass ionomer restorative system (Equia) or a micro hybrid composite(Gradia Direct). 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).

Conditions

  • Dental Caries

Interventions

OTHER

EQUIA

Placing glass ionomer restorations, the dentin and enamel of cavities were conditioned with 20% polyacrylic acid for 20 seconds, washed, and briefly dried. Equia 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 Coat was applied and photocured for 20 seconds using a photo-curing light.

OTHER

Gradia Direct Posterior

The enamel and dentin were conditioned with G-Bond 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, Gradia Direct Posterior 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.
