Design outcomes

Primary

Measure	Time frame
The aim of the study is to examine the sealing ability of different adhesives applied to carious and sound dentine of deciduous teeth. Therefore, images are taken by a scanning electron microscope (SEM), depicting the interface between carious or sound primary dentine and the filling material. The tightness of the sealing is assessed on the basis of school grades, from grade 1 (= continuous, complete transition between the filling material and dentine) to grade 6 (= loss of the filling material, so that the dentine is left with no sealing at all).	—
