“…The lower TP of the VS group compared to E.max is mostly related to its composition and the addition of 10% zirconia particles in its matrix. Notably, the values recorded in this study were higher than the ones reported by Alp and Subaşi (12.9 ±0.59 at 0.6 mm) [22].…”

“…The smoothness, and the surface quality of the prosthetic material are important to achieve the desired aesthetic appearance and long-term clinical success [43], because rough surfaces affect discoloration and shade matching. Alp and Subaşı (2019) and Al-Hebshi et al (2005) assessed the effect of khat on salivary parameters and found that it caused inadequate and decreased salivary flow rate with high viscosity and lowered the pH of saliva. These factors were associated with increased risk of teeth discoloration [44,45].…”

Background and Objectives: Khat chewing is considered as a daily habit that is practiced by more than five million people globally. The effect of khat chewing on the surface roughness and the color stability of natural teeth and the material used in the fabrication of dental prosthesis remains unknown. This study was conducted to explore and compare the effect of khat homogenate (KH) on the surface roughness (Ra) and the average color changes (ΔE*) amongst natural teeth and selected shades from different porcelain types, namely, feldspathic metal ceramic (MC) VM13, computer-aided design/computer assisted manufacture (CAD/CAM) feldspathic (Vitablocs Mark II), and multilayer zirconia (Ceramill Zolid PS) porcelains. Materials and Methods: Seventy samples were prepared from natural teeth, feldspathic MC, CAD/CAM Vitablocs Mark II, and zirconia porcelain. The Ra values were measured using a profilometer and expressed in micrometers, whereas the ΔE* values were measured using VITA Easyshade® V spectrophotometer for all samples before and after frequent immersion and thermocycling in KH for 30 days. The surface topography was used to assess the materials surfaces (glazed or polished) after KH immersion by using a white light interferometry machine. Results: Results revealed that the Ra and the ΔE* values of the different types of tested porcelain were influenced by KH. The order of surface roughness values was glazed or polished MC > polished Zircon > polished Vitablocs Mark II > natural teeth. The lowest ΔE* values were recorded for glazed Vitablocs Mark II and MC, and the values could be arranged as polished zircon > natural teeth > glazed zircon > polished MC > polished Vitablocs Mark II. P values were significantly varied (<0.001) among all the tested groups, except the zircon group (>0.05) for both Ra and ΔE*. Conclusions: KH significantly affected both surface parameter and color of glazed or polished porcelain materials and natural teeth.

“…In this study, lithium disilicate glass ceramic E-max CAD was chosen as a standard for comparison with ZLS ceramics because of its frequent use in many clinical and laboratory research papers (6,10,18) . Two ZLS (Celtra) ceramic materials with different restoration manufacturing techniques and surface finishing were also chosen as the processing method (19) and surface finishing (20) can affect the outcomes.…”

“…Thermocycling accompanied the wear simulation test did not maintain the uniform aspect of the glazed surface resulting in some defects (34) . According to the study of Alp and Subaşı, the surface roughness was increased with aging of the ZLS glass-ceramic and the type of surface finishing significantly affected the surface roughness (20) . However, the crystal size of milled Celtra Duo is smaller than that of heat pressed Celtra Press ceramic.…”

Aim:The purpose of this in vitro study was to evaluate the wear resistance and surface roughness of zirconia reinforced lithium silicate glass-ceramic (ZLS) compared to lithium disilicate glass-ceramic after simulated mastication.Materials and Methods: Thirty samples were prepared and divided according to the material of construction into three groups (n = 10). Group ( 1): E Max-CAD, Group (2): Celtra Duo ZLS, Group (3): Celtra Press ZLS. The sectioned samples of E-max CAD (Ivoclar, Vivadent, Schaan, Liechtenstein) blocks were polished and crystalized. The sectioned samples of Celtra Duo ZLS (Dentsply Sirona) blocks were glazed and fired. The Ingots of Celtra Press (Dentsply Sirona) were lab pressed, sectioned, glazed and power fired. The two-body wear testing was done using a chewing simulator integrated with thermo-cycling. Each ceramic sample was weighed and evaluated for surface roughness before and after the wear simulation test using an electronic analytical balance and optical profilometry, respectively.Results: IPS E-max CAD revealed the highest amount of weight loss with no statistically significant difference between groups as indicated by ANOVA test. The change in weight for each group was non-significant as demonstrated by paired t-test. The roughness mean value for E-max CAD was significantly decreased and recorded the lowest roughness change. Tukey's post-hoc showed a non-significant difference in the roughness mean value between Celtra Duo and Celtra Press. The roughness change for either Celtra Duo or Celtra Press groups was non-significantly increased as demonstrated by paired t-test.Conclusions: ZLS Celtra ceramics had insignificant less wear and significantly higher surface roughness with enamel antagonist compared to E-max CAD. Although wear and roughness were affected by the surface finishing of glass ceramics, the construction method of ZLS restorative materials had no significant impact on both.
