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
Introduction Direct pulp capping therapies use bio material s to protect exposed tissues , inducing repair through the production of a mineralized barrier .
The purpose of this study was to compare the effectiveness of bio material s and techniques by means of a systematic review and meta‐ analysis .
Partial pulpotomy on caries-free teeth using enamel matrix derivative or calcium hydroxide: a randomized controlled trial.
AIM To compare the effect of enamel matrix derivative ( EMD ) and calcium hydroxide [ Ca(OH)(2 ) ] on exposed human pulp . METHODOLOGY Fifteen pairs of human contralateral premolars were intentionally and partially pulpotomized . The exposed pulps were r and omly capped with either EMDgel ( Emdogain ) or a mix of Ca(OH)(2 ) and sterile water . The subjects recorded pain or discomfort during the first 10 days and were also interviewed and examined by a blinded examiner at 1 day , 2 weeks , 3 and 6 months post-operation . Periapical radiographs were taken prior to the operation , and 3 and 6 months post-operation . After 6 months , the teeth were extracted and processed for histological evaluation . The data were described and analysed using McNemar test and Kaplan-Meier survival analysis . RESULTS The EMDgel-treated teeth had significantly less tooth hypersensitivity than the Ca(OH)(2)-treated teeth during the first 2 weeks ( P = 0.031 ) but were not significantly different after 2 weeks ( P = 0.125 ) . No detectable periapical radiographic changes were observed in any teeth and radiographic evidence of dentine bridge formation from both groups were not significantly different during the follow-up periods ( P > 0.05 ) . Histological evaluation demonstrated that the Ca(OH)(2)-treated teeth had less inflammation and more dentine bridge formation than those in the EMDgel-treated teeth . CONCLUSIONS After 6 months , healthy pulps capped with Ca(OH)(2 ) had more favourable results than counterparts capped with EMDgel . However , similar clinical and radiographic results were seen in both groups
