Resumo
The aim of this study was to evaluate and compare the quantitative and qualitative inflammatory responses and bone formation potential after implantation of polyethylene tubes filled with a new calcium hydroxide containing sealer (MBPc) and Prolloot mineral trioxide aggregate (MIA). There were 48 Wistar rats divided in three groups: Group I (control group) empty polyethylene tubes were implanted in the extraction site; group II and III, polyethylene tubes were implanted filled with ProRoot mineral trioxide aggregate (MIA) and MBPc, respectively. At 7, 15, and 30 days after tube implantation, the animals were killed, the hemi-maxillas were removed and prepared to light microscopic analyses. The scores obtained were submitted to Kruskal-Wallis statistical test (p < 0.05). Significant differences between the materials were not observed. The results showed that both materials had similar biological response.
