Abstract
Objective: To evaluate the bond strength (BS), pH and solubility (Sol) of a new PBS HP®
bioceramic cement compared to MTA REPAIR HP® cement.
Material and methods: Twenty human premolars were selected for BS analysis. Roots
were cut into thirds (cervical, medium and apical) and filled with one of the cements (n=10):
PC (PBS HP) or MC (MTA REPAIR HP). Half of these samples were subjected to 2,000
thermal cycles. After 48 hours, the BS test was performed in a universal testing machine
(0.5mm/min). Cylindrical specimens (1.0mm in diameter and 10mm in height) were made
with PC or MC and immersed in distilled water for pH analysis. After 0.3 and 24 hours, the
pH was measured. Solubility was evaluated through the mass loss of the samples after 24
hours. Teflon rings of 20mm in diameter and 1.5mm in height were filled with PC or MC
and kept at 37ºC in 100% humidity. Descriptive and exploratory analyzes of BS, pH and
Sol data were performed (p<0.05).
Results: There was no significant difference in BS between the two types of cement.
Thermo cycling did not affect the BS (p>0.05). MC cement showed significantly higher pH
values than the PC at the initial and 3 hours (p<0.05). There was no difference between them
(p>0.05) after 24 hours. There was no significant difference regarding solubility (p>0.05).
Conclusion: Bioceramic cements have similar properties, as they did not differ in relation
to dentin bond strength, pH after 24 hours and solubility.
