3Y-TZP showed the smallest grain size and cubic content. A significant amount of wear was observed in both materials up to 50,000 cycles until it reached a plateau. MULTI showed higher volume loss and greater wear depth than 3Y-TZP (p < 0.01). The higher volume loss was associated with extensive lateral fracture, leading to material spalling from the surface of cubic-containing zirconias.

The wear pattern in multi-layered zirconia was more severe than 3Y-TZP. Additionally, the different layers of the multi-layered zirconia had similar wear behavior.

Known as dental sclerosis, this process begins at the root apex, progresses coronally, and is associated with a degradation in the resistance to fracture of dentin.
To determine i) age-related changes of intertubular dentin with aging, particularly within the root, and ii) the differences in age-related degradation between vital and pulpless (i.e. non-vital) teeth.

We performed nanoscopic dynamic mechanical analysis (nanoDMA) in scanning mode on the intertubular and peritubular dentin of teeth from young and old adults. The complex, loss and storage moduli, as well as the tan delta parameter were evaluated for teeth with no restorations and teeth with root canal treatment (non-vital).

There were significant changes in the dynamic moduli of intertubular dentin with age, which were most substantial in the apical third of the root. The storage modulus of the intertubular dentin, which quantifies the purely elastic resistance to deformation, was significantly (p < 0.0005) larger for both the old vital and non-vital teeth than that of the young teeth, over the entire root length. However, the tan delta parameter, which quantifies the relative capacity for viscous deformation, was significantly lower in these two groups (p < 0.005).

Radicular dentin undergoes an embrittlement with aging, involving reduced capacity for viscous deformation. The extent of degradation is largest in the apical third. Removal of the pulp appears to accelerate the aging process or compound the extent of degradation.

The aim of this study was to explore elderly patients' beliefs about medicines in general, and specific towards their treatment and the relationship between beliefs and adherence.

A cross-sectional study was performed by administering a questionnaire developed to meet the study's objectives. Elderly patients were recruited from three different settings.

167 patients agreed to participate to our study, having a mean age of 73 years. Patients were aware of the necessity for treatment, but they also showed concern over the potential for the adverse outcomes. Only 15% of the patients were completely accepting their treatment having high necessity and low concerns, while 40% were ambivalent, having high necessity beliefs, but also high concerns, with 89% being adherent in this group. Overall, higher adherence was significantly correlated with higher necessity and with higher necessity-concern differential.

Patients beliefs have an impact on adherence, thus patients' concerns and necessities should be addressed in order to improve adherence and treatment outcome.

Higher necessity positively influenced adherence to treatment, suggesting the fact that healthcare professionals could improve patients' adherence by outlining and educating the patients on the necessity of the treatment, while also managing patients' concerns.

A mixed-method study involving patient focus groups and survey of primary care providers (PCPs) sought to compare perspectives about chronic pain (CP) and its treatment. Our goal was to identify needs and barriers for facilitating patient-centered care.

Two focus groups of CP patients from a single academic medical center explored interactions with PCPs and their understandings, experiences, and expectations of CP treatment. They were also asked their opinions about self-assessment/communication tools. We compared themes with survey data from two PCP research networks.

CP patients understand opioid risks and fear PCP judgement and condescension, while sensing PCP fear and avoidance of opioid prescribing. PCPs are dissatisfied with their ability to provide optimal CP care, despite feeling that patients are generally satisfied with their clinic visits. Evaluation tools, especially assessment of functional activities, are favorably viewed by all, but deemed time prohibitive.

Patients' understanding of opioid risks, desire for attention on functional goals and behavioral treatment may be greater than PCPs perceive. Such gaps in understanding and attitudes, if recognized, could support high-quality communication and interventional strategies.

These findings guide patient-PCP communication toward alignment of treatment goals and enhanced coordination of care.

The fracture incidence of implant-supported overdentures is more frequent in the area of attachment because of stress concentration and denture deformation in this area. How E-glass fiber reinforcement can address this problem is unclear.

The purpose of this invitro study was to evaluate the influence of unidirectional E-glass fiber reinforcement on the mid-line denture base strains of single implant-supported overdentures.

An experimental acrylic resin cast was constructed with a single implant placed in the mid-line area and a ball attachment screwed to the implant. Twenty-four experimental overdentures were constructed and divided into 4 groups group AP fabricated from autopolymerizing acrylic resin without fiber reinforcement, group APF fabricated from autopolymerizing acrylic resin with unidirectional E-glass fiber reinforcement running over the residual ridge and the ball matrix, group HP fabricated from heat-polymerized acrylic resin without fiber reinforcement, and group HPF fabricated from heatrded significantly lower strain values by almost 50% than those of group AP and group HP (P<.05).

Unidirectional E-glass fiber reinforcement placed over the residual ridge and implant attachment significantly reduced denture base strains and deformation of single implant-supported overdentures.

Although contemporary analytical methods are available for application to data which exhibit a lack of equality of variances or a lack of normality in the error distribution, little guidance is provided for selecting the methods of data handling and analysis which best fit color difference data for stained esthetic materials.

The purposes of this invitro study were to apply information criteria of analysis of variance (ANOVA)methods of differing error distributions and covariance structures when analyzing color differencesto determine the degree of alienation among 3 Commission Internationale de l'Eclairage (CIE) color difference formulaeto assess the linearity of relationships among these formulaeand to independently assess differences among various computer-aided design and computer-aided manufacture (CAD-CAM)materials in any color change after common forms of staining over time.

Hybrid ceramic, resin nanoceramic, feldspathic-ceramic, and lithium-disilicate ceramicspecimens (N=128) were subjected to s linear correlation between the 3 color difference formulae studied, each formula is unique, and each represents a different assessment of the perceived color difference. CAD-CAM materials, staining liquids, and time points affected the notable color changes.Precise preparation of guiding planes is essential for removable partial dentures (RPDs). MDL-28170 clinical trial This report introduces a metal template fabricated by computer-aided design and computer-aided manufacturing (CAD-CAM) to help prepare guiding planes for RPDs.
Although studies have reported the accuracy of 3D-printed dental casts, studies addressing cast distortion throughout the complete-arch range are lacking.

The purpose of this invitro study was to evaluate the dimensional accuracy of different areas in complete-arch casts made with various 3D printing methods.

A computer-aided design (CAD)reference cast was modified from a mandibular cast by adding 6 cylinders in the canine, second premolar, and second molar locations and 3 spheres to define a coordinate system. A total of 50 casts were printed with 5 group materials, which included fused deposition modeling (FDM), digital light processing (DLP1 and DLP2), photopolymer jetting (Polyjet), and stereolithography (SLA). After scanning the 3D printed casts, the overall consistency was examined by superimposing them on the CAD reference cast and measuring the deviations. For dimensional accuracy, cylinder top coordinates were extracted from each printed cast, and X-, Y-, and Z-deviations and the 3D deviation wions were smaller than those in the other directions.
FDM and DLP casts tended to contract, whereas casts in the Polyjet and SLA groups expanded buccolingually and anterioposteriorly. Vertically, deviations were smaller than those in the other directions.In this paper, a time series model based on hybrid-kernel least-squares support vector machine (HKLSSVM) with three processes of decomposition, classification, and reconstruction is proposed to predict short-term wind power. Firstly, on the basis of the maximal wavelet decomposition (MWD) and fuzzy C-means algorithm, a decomposition method decomposes wind power time series and classifies the decomposition time series components into three classes according to amplitude-frequency characteristics. Then, time series models on the basis of least-squares support vector machine (LSSVM) with three different kernels are established for these three classes. Non-dominated sorting genetic algorithm II optimizes the parameters of each forecasting model. Finally, outputs of forecasting models are reconstructed to obtain the forecasting power. The proposed model is compared with the empirical-mode-decomposition least-squares support vector machine (EMD-LSSVM) model and wavelet-decomposition least-squares support vector machine (WDLSSVM) model. The results of the comparison show that proposed model performs better than these benchmark models.Exogenous disturbances largely affect the control performance of systems with time delays. This study considers a control problem of rejecting a disturbance in a PI control system for a time-varying state-delay plant. The equivalent-input-disturbance (EID) approach is integrated in a PI control system. An EID estimator estimates the overall effects of a time-varying delay and a disturbance. An EID estimate is combined into a PI control law to improve control performance. A less-conservative stability condition of the control system is derived using a Lyapunov-Krasovskii functional together with the Jensen's integral inequality and the reciprocally convex combination lemma. Parameters of the controllers in the system are calculated using the condition. Engine idle speed control is used to verify the effectiveness of this approach. Compared with the generalized extended-state observer and the sliding-mode control methods, our method reduced the tracking error to about one third and one sixth, respectively. This demonstrates the validity and superiority of our method.
