| description | Aims and background: In primary molars, pulpotomy is recommended when the radicular pulp tissue is either healthy or capable of healing. A biologically compatible pulpotomy agent is used to seal the radicular pulp. The biocompatibility, sealing ability, and adaptability of these materials to the overlying restoration play an important role in the outcome of pulpotomy. Mineral trioxide aggregate (MTA) is a recently sought-after pulpotomy agent. However, there is a need to evaluate the newer premixed bioceramics as pulpotomy agents, due to the difficult handling characteristics of the conventional calcium silicate-based cements. To evaluate shear bond strength (SBS) and marginal adaptation of calcium silicate-based cement and premixed bioceramics when restored with glass ionomer cement (GIC) immediately.
Materials and methods: Forty extracted primary molars were randomly divided into two equal groups according to the material used (group I—e-MTA® Cement and group II—e-MTA Putty). Half of the samples from each group were allotted to two test groups for SBS and marginal adaptation evaluation. Calcium silicate-based cement and premixed bioceramics were used in the determined standardized thickness, and both groups were restored with GIC. The SBS was evaluated using a universal testing machine. Field emission scanning electron microscope (FE-SEM) analysis was performed to evaluate the marginal adaptation. The mean SBS and mean marginal adaptation were determined using an unpaired <i>t</i>-test.
Results: The mean SBS value of calcium silicate-based cements was higher than premixed bioceramics; however, no significant difference in SBS values was reported for both groups (<i>p</i> = 0.058). Fewer gaps were seen between GIC and premixed bioceramics group, thus demonstrating better marginal adaptation than calcium silicate-based cements which was statistically significant (<i>p</i> = 0.000).
Conclusion: Premixed bioceramics showed better marginal adaptation as compared to calcium silicate-based cements and similar SBSs, making them a good alternative to the conventional calcium silicate-based cements with the added advantage of better handling properties.
Clinical significance: This study helped to evaluate the newer premixed bioceramics that pose an advantage of a decrease in chairside time as compared to conventional calcium silicate-based cements. |
