dc.description.abstractObjective: The aim of this study is to evaluate the effects of Er,Cr:YSGG laser debonding on the mechanical properties of aged and non-aged lithium disilicate ceramics. Materials and Methods: A total of 36 lithium disilicate samples with dimensions of 14x4x1 mm were prepared. Half of the samples underwent 5000 thermal cycles to simulate artificial aging. The aged and non-aged samples were divided into two subgroups: one subgroup was designated as the control group and did not receive laser treatment, while the other subgroup was treated with Er, Cr:YSGG laser for debonding (n=9). The flexural strength and modulus of the lithium disilicate samples were assessed using three-point bending tests before and after artificial aging. The surface roughness of a sample that did not undergo the three-point bending test was measured with AFM, its microhardness was assessed using the Vickers hardness test, and surface morphology was examined with FESEM. Two-way ANOVA and Bonferroni correction to determine the significance of the results were used for statistical analysis. Results: The results indicated that aging significantly reduced the flexural strength (p=0.031), however, laser debonding did not have a significant effect on the flexural strength or elastic modulus of either aged or non-aged samples. Aged groups had higher roughness. No fractures or microcracks were observed in any group in FESEM analysis. Conclusion: Laser debonding effectively removes lithium disilicate restorations without compromising their mechanical properties, supporting their reuse in clinical practice. It is important to note that aging reduces the flexural strength of lithium disilicate ceramics.
