The overall results of the computed data sets suggest that GIC has a higher caries-preventive effect than amalgam for restorations in permanent teeth .
No difference was found for restorations in the primary dentition .
Background This article aims to up date the existing systematic review evidence elicited by Mickenautsch et al. up to 18 January 2008 ( published in the European Journal of Paediatric Dentistry in 2009 ) and addressing the review question of whether , in the same dentition and same cavity class ,  glass-ionomer cement ( GIC ) restored cavities show less recurrent carious lesions on cavity margins than cavities restored with amalgam .
Evidence favoring the use of anticoagulants in the hospital phase of acute myocardial infarction.
Since the last comprehensive review of anticoagulation in acute myocardial infa rct ion four additional r and omized control trials have been reported . The overwhelming majority of all trials favored anticoagulation .  Rates of thromboembolism were higher in the control , and hemorrhagic complications in the anticoagulated group . Pooling of all r and omized control trials gives mean case fatality rates of 19.6 % for the control and 15.4 % for the anticoagulated group , a relative reduction of 21 % ( P less than 0.05 or less than 0.001 , depending on the analytic method ) . Five of six r and omized control trials reported " no effect " because the difference favoring anticoagulation was not statistically significant . However , sample sizes in these " negative " papers were too small to protect against missing a 21 % reduction in true case fatality rate due to anticoagulation ( beta greater than 0.10 ) . All patients who present no specific contraindication should receive  anticoagulants  during hospitalization for infa rct ion
