Light cured glass ionomer cements offer improved handling characteristics. Photocuring within the cavity preparation may assist in decreasing the moisture contamination and dehydration difficulties associated with the early stage of setting reaction. The success of restoration depends on good adhesion between glass ionomer cement and the tooth structure. Various dentin conditioners have been ad...

This study determined the shear bond strength of resin composites to primary dentin using three dentin adhesives and the presence or absence of a hybrid zone. The buccal and lingual surfaces of 40 recently extracted noncarious primary teeth were ground flat with SiC paper ending with the 600 grit. The teeth were divided at randomly into eight groups of five teeth (10 surfaces) each: 1) Unetched...
