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

Pulpal Responses to Direct Capping with Betamethasone/Gentamicin Cream and Mineral Trioxide Aggregate: Histologic and Micro-Computed Tomography Assessments.
INTRODUCTION This clinical trial was conducted to evaluate the response of human dental pulp to direct capping with betamethasone/gentamicin ( BG ) cream and mineral trioxide aggregate ( MTA ) . We hypothesized that the results of direct pulp capping with a topical BG combination would be similar to or better than those with MTA . METHODS Thirty-six human first premolar teeth scheduled for orthodontic extraction were r and omly divided into 4 groups : BG1 group ( n = 9 ) , BG cream with 2-week follow-up ; BG2 group ( n = 10 ) , BG cream with 8-week follow-up ; MTA1 group ( n = 8) , MTA with 2-week follow-up ; and MTA2 group ( n = 9 ) , MTA with 8-week follow-up . Teeth were extracted and evaluated at respective time intervals . Micro-computed tomography scanning and histologic analyses were performed for all specimens . Pulp pathology ( inflammation , pulp abscesses , and pulp necrosis ) and reparative reaction ( formation of dentin bridges ) were recorded . RESULTS Both BG cream and MTA result ed in significantly better pulpal responses at 8 weeks than at 2 weeks . Dentin bridge formation was significantly thicker in the MTA group at 8 weeks than in any other group ( P < .05 ) . Inflammation was of the acute type in all groups ; no statistically significant differences in the distribution of inflammatory cells were found among the groups . Pulpal abscesses and /or necrosis were observed more often in teeth capped with BG than with MTA . CONCLUSIONS Direct pulp capping with both BG cream and MTA was associated with dentin bridge formation . MTA result ed in a significantly better pulpal response , with less inflammation and a thicker dentin bridge at 8 weeks
