【 摘 要 】

The aim of this study was to examine the effect of Biodentine® and two newnanostructured materials based on active silicate cements on exposed toothpulp of Vietnamese pigs. The study comprised 40 teeth in two Vietnamese pigs(24 months old). After class V cavity preparation, the pulp on each tooth wasexposed using a small round bur. The following materials were applied on pulpexposures: Biodentine® (10 teeth), ALBO MPCA-I (10 teeth), and ALBO MPCA-II(10 teeth). In the control group, exposed pulp was covered with ProRoot MTA®(10 teeth). After the observation period of 28 days, the animals weresacrificed and the teeth prepared for histological analysis. Light microscopewas used for the analysis of dentin bridge formation, tissue reorganizationand inflammation, and the presence of bacteria in the pulp. In the group ofBiodentine®, a complete dentin bridge was noted in 3 cases, while incompletedentin bridge in the form of dental islets was detected in 4 cases.Nanostructured material ALBO-MPCA I provided complete dentin bridge formationin 5 teeth, in 3 teeth the formed dentin bridge was incomplete. ALBO MPCA-IIshowed complete closure of the pulp opening by dentin bridge in 4 samples,while in the same number of teeth it was incomplete. In the control group, 4teeth showed a complete dentin bridge, whereas in 6 teeth it was incomplete.Histological analysis indicated favourable therapeutic effects of Biodentine®and the two materials ALBO-MPCA I and ALBO-MPCA II after teeth pulp cappingin Vietnamese pigs. Pulp reaction was similar to that caused by ProRoot MTA®.[Projekat Ministarstva nauke Republike Srbije, br. ON172026]
