ABSTRACT

Introduction: The aim of this study is to measure the strength needed to debond ceramic cylinders by using CO₂ and Er,Cr:YSGG lasers. Materials and methods: The in vitro experiment consists of 60 human teeth divided in 3 groups: Group 1 control, Group 2 with 3 seconds application of CO₂ laser, and Group 3 with 5 seconds application of Er,Cr:YSGG laser. The 3mmx3mm cylinders are made with E-max Press pressed ceramic and are cemented to the teeth with Relyx ®. After the laser application on the samples, a Shear Bond Tester device was used to measure the shear strength. Results: Significant differences are found between the Group 1 control and the two treated with laser (p<0.001). Conclusion: The use of CO₂ and Er,Cr:YSGG lasers can be considered as a valid and safe method of ceramic restoration debonding. Further studies are necessary to evaluate different currents, the use water spray and different debonding times.
