RESULTS No statistical significant difference in bond strength between both categories was observed in caries-affected dentin at immediate evaluation and in sound dentin after ageing .
Etch- and -rinse adhesives , however , performed better in sound enamel and dentin substrates considering immediate bond strength .
None study assessed the long-term adhesive effectiveness to sound or demineralized enamel .
Although the articles included in this meta- analysis showed high heterogeneity and high risk of bias , the in vitro literature suggests superior performance of etch- and -rinse adhesives in primary teeth in comparison with self-etch systems
AIM To systematic ally review the literature for in vitro studies that evaluated the immediate or after ageing bond strength of  etch- and -rinse and self-etch adhesive systems to enamel and dentin of primary teeth .
Effect of adhesive restorations over incomplete dentin caries removal: 5-year follow-up study in primary teeth.
PURPOSE The purpose of this study was to evaluate the effect of the material s used for indirect pulp treatment ( IPT ) on the long-term outcome of primary molar teeth . METHODS Forty-eight teeth with deep carious lesions , but without signs and symptoms of irreversible pulpitis , were r and omly divided into 2 groups , according to the material placed on the demineralized dentin remain : ( 1 ) experimental group , adhesive system ( Scotchbond Multi purpose ) ; and ( 2 ) control group , calcium hydroxide liner ( Dycal ) . Both groups were followed by a resin restoration application . RESULTS After 4 to 5 years , the clinical and radiographic success rates between groups were similar ( group 1=14 of 15 ; group 2=8 of 10 ; P=0.350 ) . Subsequent to exfoliation , scanning electron microscopy revealed the presence of a hybrid layer at the resin-dentin interface and a microtensile bond strength of 9.63 MPa ( group 1 ) . Histological analysis showed that the pulp health status was similar in both groups . CONCLUSIONS Indirect pulp treatment has a high clinical and radiographic long-term success rate in primary teeth and is not material -dependent
