Conclusions MTA cements have a higher success rate , with a lower inflammatory response and a more predictable hard dentin barrier formation  than calcium hydroxide cements .
However , there were no differences , in these parameters , when MTA cement was compared with tricalcium silicate cements .
Dental adhesives systems showed the lowest success rates

Evaluation of two mineral trioxide aggregate compounds as pulp-capping agents in human teeth.
AIM The present r and omized , controlled prospect i ve study evaluated the histomorphological response of human dental pulps capped with two grey mineral trioxide aggregate ( MTA ) compounds . METHODOLOGY Pulp exposures were performed on the occlusal floor of 40 human permanent pre-molars . The pulp was capped either with ProRoot ( Dentsply ) or MTA-Angelus ( Angelus ) and restored with zinc oxide eugenol cement . After 30 and 60 days , teeth were extracted and processed for histological examination and the effects on the pulp were scored . The data were subjected to Kruskal-Wallis and Conover tests ( alpha = 0.05 ) . RESULTS In five out of the 40 teeth bacteria were present in pulp tissue . No significant difference was observed between the two material s ( P > 0.05 ) in terms of overall histological features ( hard tissue bridge , inflammatory response , giant cells and particles of capping material s ) . Overall , 94 % and 88 % of the specimens capped with MTA-Angelus and ProRoot , respectively , showed either total or partial hard tissue bridge formation ( P > 0.05 ) . CONCLUSIONS Both commercial material s ProRoot ( Dentsply ) and MTA-Angelus ( Angelus ) produced similar responses in the pulp when used for pulp capping in intact , caries-free teeth
