Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Clinical evaluation of materials retention - no difference in resistance between the materials evaluated;Clinical evaluation of materials retention - success rate of 100% in the control group and 65% for the experimental group;Radiographic evaluation of lesion - arrestment of dental caries in both groups;Radiographic evaluation of lesion - absence of caries progression of in 100% of cases in both groups | — |
Secondary
| Measure | Time frame |
|---|---|
| The exfoliated teeth were collected for evaluation of the morphology of the adhesive interface by analysis in Scanning Electron Microscopy.It was visualized formation of hybrid layer, with the presence of adhesive system tags in affected dentin in control group and areas not filled with adhesive system in the interface tooth/restoration for experimental group. | — |
