For that purpose, 40 extracted decayed human molars were divided into 4 groups: GI (burs + Prime & Bond NT + TPH), GII (Carisolv + Prime & Bond NT + TPH), GIII (burs + SBMP + Z100) and GIV (Carisolv + SBMP + Z100). After accomplishment of the restorations and thermal cycling, the teeth were exposed to dye, sectioned and qualitatively evaluated. The results demonstrated that the system of removal of carious tissue did not influence the results of microleakage at any of the cavity margins. At dentinal margins, use of the Prime & Bond NT + TPH restorative system allowed the occurrence of less microleakage than the SBMP + Z100 system.176-181engDental cariesDental leakageDental restorationPermanentCarisolvglutamic acidleucinelysineresintooth cementunclassified drugchemistrycomparative studydental bondingdental cariesdental surgeryendodonticshumanin vitro studymaterials testingmethodologystandardtooth diseaseComposite ResinsDental BondingDental CariesDental Cavity PreparationDental CementsDental LeakageDental Restoration, PermanentGlutamic AcidHumansLeucineLysineMarginal Adaptation (Dentistry)Materials TestingArtigo10.1590/S1806-83242007000200014S1806-83242007000200014Acesso aberto2-s2.0-345478280572-s2.0-34547828057.pdf43012687750188645761956467234702
