Purpose.
To investigate the cavity adaptation of mineral trioxide (ProRoot MTA/MT), tricalcium silicate (Biodentine/BD), and glass ionomer (Equia Fil/EF) cements used as liners and the interfacial integrity between those liners and a composite resin placed as the main restorative material.
Materials and Methods.
Standardized class I cavities (n: 8 per group) were prepared in upper premolars.
Cavities were lined with a 1 mm thick layer of each of the tested materials and restored with Optibond FL adhesive and Herculite Precis composite resin.
Cavity adaptation of the restorations was investigated by computerized X-ray microtomography.
The regions of interest (ROI) were set at the cavity-liner (CL) interface and the liner-resin (LR) interface.
The percentage void volume fraction (%VVF) in the ROI was calculated.
The specimens were then sectioned and the interfaces were evaluated by reflection optical microscopy, to measure the % length (%LD) of the interfacial gaps.
Selected samples were further evaluated by scanning electron microscopy.
Statistical analysis was performed by two-way ANOVA and Student-Newman-Keuls multiple comparison test (a=0.05).
Results.
MT showed significantly higher %VVF and %LD values in CL interfaces than BD and EF (p<0.05).
No significant differences were found among the materials for the same values at the LR interfaces.
Conclusions.
When used as a composite liner, ProRoot MTA showed inferior cavity adaptation at dentin/liner interface when compared to Biodentine and Equia Fil.
