This study evaluated the response of the dental pulps of dog teeth to capping with mineral trioxide aggregate (MTA) or calcium hydroxide P.A. For that purpose, 37 teeth were divided into two groups, according to the capping material employed. Two dogs were anesthetized and, after placement of a rubber dam, their pulps were exposed in a standardized manner and protected with the experimental capping materials. The cavities were then sealed with resin-modified glass ionomer cement and restored with composite resin. After sixty days, the animals were killed and the specimens were processed in order to be analyzed with optic microscopy. It was observed that MTA presented a higher success rate compared to calcium hydroxide, presenting a lower occurrence of infection and pulp necrosis.219-225engBiocompatible materialsCalcium hydroxideDental pulp cappingaluminum derivativebiomaterialbone cementcalcium derivativecalcium hydroxidemineral trioxide aggregateoxideresinsilicateanimaldentindisease modeldogdrug combinationdrug effectendodonticsmethodologynonparametric testpathologystandardtooth pulpAluminum CompoundsAnimalsBiocompatible MaterialsBone CementsCalcium CompoundsCalcium HydroxideComposite ResinsDental PulpDental Pulp CappingDental Pulp ExposureDentinDisease Models, AnimalDogsDrug CombinationsOxidesPulpotomySilicatesStatistics, NonparametricArtigo10.1590/S1806-83242006000300007S1806-83242006000300007Acesso aberto2-s2.0-337503452792-s2.0-33750345279.pdf576195646723470264262046566569638813777272581972
