Assessment of Marginal Adaptation and Microleakage of Ceramic Crowns Cemented with Different Luting Agents- A Comparative Study

Abstract

Aim: The aim of the present study was to assess the marginal integrity and microleakage of ceramic crowns cemented with different luting agents.

Materials and Methods: A total of forty-five sound maxillary first premolar teeth were included in this study. All teeth were marked 2 mm apical to the CEJ with a permanent marker. Each tooth was then embedded into a block of acrylic resin.Crown preparation and fabrication was done by a calibrated and trained researcher. All forty-five samples were randomly allotted to the one of the following group for cementation.Group 1: Fuji I glass ionomer cement, Group 2: Riva Luting Plus resin-modified glass ionomer cement, Group 3: RelyX ultimate adhesive resin cement. All premolar samples were subjected to thermocycling process at 5°C ± 2°C along with 55°C ± 2°C for 500 cycles. Microleakage patterns were fully registered using stereomicroscope 10X magnification.

Results: The least microleakage was found in RelyX ultimate adhesive resin cement group (1.04± 0.08), followed by the Riva Luting Plus resin-modified glass ionomer cement group (1.28± 0.11) and then the Fuji I glass ionomer cement group (2.16 ± 0.06). And the statistically significant difference was between the different luting cements.

Conclusion: Within the limitation, the present study concluded that theleast microleakage was found in RelyX ultimate adhesive resin cement group compared to Riva luting plus resin-modified glass ionomer cement group and Fuji I glass ionomer cement group.
