ABSTRACT
Purpose/Aim: To determine the effect of translucency of four CAD/CAM materials and different curing modes on the degree of conversion of resin cements. Materials and Methods: Disks were fabricated from IPS e.max CAD, Vita Suprinity, Vita Enamic, and DD Cube X². Translucency was measured using a spectrophotometer. The degree of conversion of two resin cements Variolink Esthetic DC and LC were measured using a Fourier transform infrared spectrometer. For Esthetic DC, the degree of conversion was determined in self-cure and dual cure modes. ANOVA, Tukey HSD test, and /Linear Regression R2 were used to statistically analyze the data. Results: There was a significant difference in the translucency of the four materials (P ⟨ 0.0001). The mean translucency of Vita Suprinity was significantly higher, followed by Vita Enamic, DD Cube X², and IPS E.max CAD. Degree of conversion of resin cements cured under DD Cube X² had the highest values (25.22%), whereas those cured under Vita Suprinity showed the lowest values (17.86%). The self-cure mode had the lowest degree of conversion values (16.22%) and dual cure mode showed the highest values (26.12%). A negative linear relationship was found between degree of conversion and translucency of the CAD/CAM materials.
