Comparison of Different Cleansing Agents for Decontamination of Lithium Disilicate Ceramics

Aim: The aim of this in-vitro study was to investigate the efficacy of three cleansing agents for decontamination of lithium disilicate (LD) ceramics. Material and Methods: Six LD ceramics (IPS e.max Press, Ivoclar Vivadent, Schaan, Liechtenstein) (4x4 mm) were fabricated. Composite discs were also fabricated with the same size of ceramics. Ceramic discs were contaminated with a light body impression material. Ceramic discs were then divided into 3 groups according to the cleansing method Group I (Ivoclean), Group E (Ethyl alcohol) and Group U (Ultrasonic cleaning with detergant). Composite and ceramic discs were cemented with adhesive cement (Variolink N). The composite-ceramic discs were embedded in polymethylmetacrilate. Specimens were then cut with low-speed diamond knife (Isomet, Buehler, IL, USA) into 1x1x8 mm bars. There were 18 bars for every group. The bars were positioned in a universal testing machine (Lloyd, Hampshire, UK) for microtensile test 0.5 mm/min, 50kgf load cell). Data were recorded then statistically analyzed with Levene, one-way ANOVA and Tukey tests (p=0.05). Results: The highest bond strenght were seen in Group E (ethyl alcohol) (41.28±12.05 MPa) and the lowest were seen in Group U (30.51±11.64 MPa) (p=0.048). There were no statistically significant differences between Group I (34.88±15.51) and Group E, Group I and Group U either. Conclusion: Ethyl alcohol showed effective cleaning and the highest bond strength value than the Ivoclean and ultrasonic cleaning. All cleaning methods in this study showed acceptable bond strength values within the acceptable clinical ones.
