“…Light exposure and humidity changes can be simulated artifical aging process which has been widely used for the testing of dental resin and ceramic materials 11,43,44) . The manufacturer of the universal test machine used in this study claimed that 300 h of artificial aging is equivalent to 1 year of clinic service.…”

The purpose of this study was to investigate the flexural strength of all-ceramics with varying core thicknesses submitted to aging. In-Ceram Alumina (IC), IPS e.max Press (EM) and Katana (K) (n=40), were selected. Each group contained two core groups based on the core thickness as follows: IC/0.5, IC/0.8, EM/0.5, EM/0.8, K/0.5 and K/0.8 mm in thickness (n=20 each). Ten specimens from each group were subjected to aging and all specimens were tested for strength in a testing machine either with or without being subjected aging. The mean strength of the K were higher (873.05 MPa) than that of the IC (548.28 MPa) and EM (374.32 MPa) regardless of core thickness. Strength values increased with increasing core thickness for all IC, EM and K regardless of aging. Results of this study concluded that strength was not significantly affected by aging. Different core thicknesses affected strength of the all-ceramic materials tested (p<0.05).

“…[4][5][6] Translucency has been emphasized as one of the primary factors in controlling the esthetic outcome 7 because it makes ceramic and resinbased restorations appear more natural. 8,9 As translucency permits the passage of light and also disperses light, it could be described as a state between complete opacity and transparency, 10 the light being diffused rather than reflected or absorbed. [11][12][13][14] Errors in brightness among teeth are considered the most noticeable esthetic error [15][16][17] because the human eye is more sensitive to the differences in value (brightness) than hue or chroma.…”

“…Translucency is emphasized as one of the primary factors in controlling the esthetic outcome because it makes restorations appear more natural [2,3]. Requirements for dental esthetic materials are contradictory since translucency of restorative materials influences the masking ability and color blending effect [4].…”

Translucency of dental ceramics, esthetic posts and orthodontic brackets was reviewed. Translucency parameter (TP) and contrast ratio (CR) are generally used for translucency evaluation. For the evaluation of translucency, two criteria such as the translucency of human teeth (TP = 15–19, 1 mm thick) and the visual perceptibility threshold for the translucency difference (∆CR > 0.07 or ∆TP > 2) were used. In ceramics, translucency differences were in the perceptible range depending on the type of material and the thickness. However, variations caused by the difference in the required thickness for each layer by the material and also by the measurement protocols should be considered. As to the translucency of esthetic posts, a significant difference was found among the post systems. Translucency was influenced by the bracket composition and brand, and the differences by the brand were visually perceptible.
