Resin infiltration enhanced the SBS of porcelain discs bonded to demineralized enamel when compared with the other demineralization-inhibiting methods. Clinical Relevance: Resin infiltration could be useful to enhance adhesion of glass-ceramics to teeth with white spot lesions. “
“Although milled titanium may be used as a substructure in fixed and implant prosthodontics, the application of the veneering porcelain presents particular challenges compared to traditional alloys. To address these challenges, some Ti ceramic systems incorporate the application of a bonding agent
prior to the opaque layer. Vita Titankeramik’s bonding agent is available as a powder, paste, and spray-on formulation. We examined the effect of these three application methods on the https://www.selleckchem.com/products/LBH-589.html bond strength. Four titanium bars were milled from each of 11 wafers cut from grade II Ti using the Kavo Everest milling unit and a custom-designed milling toolpath. An experienced technician prepared the 25 × 3 × 0.5 mm3 metal bars and applied bonding agent using one of three application methods, and then applied opaque, dentin, and enamel porcelains according to manufacturer’s instructions to a 8 × 3 × 1 mm3 porcelain. A control group received no bonding
agent prior to porcelain application. The four groups (n = 11) were blindly tested for differences in bond strength using a universal testing machine in a three-point bend test configuration, based ICG-001 concentration on ISO 9693–1:2012. The average (SD) bond strengths for the control, powder, paste, and spray-on groups, respectively, were: 24.8 (2.6), 24.6 (2.6), 25.3 (4.0), and 24.1 (3.9) MPa. One-way ANOVA and Tukey’s multiple comparison tests Docetaxel order were performed between all groups. There were no statistically significant differences among groups (p = 0.951). Titanium-porcelain bond strength was not affected by the use of a bonding agent or its application method when tested by ISO 9693–1 standard. “
“An edentulous patient’s
psychosocial attributes that may have influence on the oral health-related quality of life (OHRQoL) are given little consideration in therapeutic care. The aim of this study was to assess the impact of complete denture therapy on overall OHRQoL in elderly edentulous patients. The possible role of the patient’s initial expectation toward OHRQoL was also evaluated. OHRQoL was assessed using the OHIP-EDENT psychometric instrument, and 56 patients participated in the study. The assessment was done at three time points including pretreatment, after 1 month, and after 6 months. Significant differences in the OHIP-EDENT scores between pretreatment to after 1 month and pretreatment to after 6 months were calculated using Wilcoxon Signed Rank test (p < 0.05). Mann-Whitney test was used to analyze the association of patient expectations with OHIP-EDENT scores. Statistically significant improvement in OHRQoL after complete denture therapy at both 1 and 6 months postinsertion was evident.
