To investigate the effect of training on scanning times of complete-arch scans (CAS) performed by first-time users, with a distinction made between specific training (repeated practice of CAS) and nonspecific training (simple use of an intraoral scanner for a sextant scan in the context of a student CAD/CAM course).

Thirty-six students with no experience in intraoral scanning were randomized into three groups (n = 12 per group) according to the number of specific CAS training sessions three sessions (3S), two sessions (2S), and one session (1S). Each student performed 10 CAS per scanning session. SJ6986 These sessions were scheduled at baseline (T
), T
(2 weeks after T
), and T
(4 weeks after T
) for group 3S; at T
and T
for group 2S; and at T
for group 1S. Before the final scanning session in each group (ie, the first scanning session in group 1S), the students participated in a CAD/CAM course (3 weeks after T0) in which a monolithic crown was fabricated in a fully digital chairside workflow. The sises at least 12 CAS.
Training does affect the scanning time required for CAS. To perform such scans in a time-efficient manner, dental practitioners should undertake training that comprises at least 12 CAS.
To evaluate and compare the occlusal fit of zirconia crowns designed using a digital articulator method and the traditional method in a self-controlled clinical trial.

Two zirconia crowns each were prepared for 12 patients with a single posterior tooth defect using two different methods a digital articulator method and the traditional method. In the traditional method, casts were scanned using a model scanner, and the relative positions of the maxillary and mandibular arches were determined by the intercuspal occlusion of the casts. In the digital articulator method, casts were mounted on a mechanical articulator and scanned, and the relative positions were determined by their respective positions in the articulator. Additional dynamic occlusal adjustments of the digital articulator crowns were performed. Both groups of zirconia crowns were milled in a five-axis milling machine. The time required for occlusal adjustments, the occlusal contacts, the occlusal contact distributions, the number of occlusal co
To determine whether the use of implant-supported overdentures (IODs) with different attachments influences the Mini Nutritional Assessment (MNA) and Geriatric Oral Health Assessment Index (GOHAI) scores in edentulous patients > 65 years of age.

The MNA and GOHAI were administered to 54 edentulous patients > 65 years of age (mean age = 68.35 ± 4.1 years) before treatment (A) and 6 months after treatment (B) 10 with maxillary + mandibular conventional complete dentures (CDs); 10 with a maxillary conventional CD + mandibular magnetic-retained IOD; 12 with a maxillary conventional CD + mandibular ball-retained IOD; 12 with a maxillary conventional CD + mandibular Locator-retained IOD; and 10 with a maxillary conventional CD + mandibular bar-retained IOD. Statistical differences between treatment types were evaluated using one-way analysis of variance and paired-sample t tests. The correlation between MNA and GOHAI scores was determined using Pearson correlation analysis (α = .05).

The difference between mean GOHAI-A and GOHAI-B scores was statistically significant for each type of denture (P < .005). The difference between the mean MNA-A and MNA-B scores was statistically significant for all types of denture except for conventional CDs (P < .05). There was a statistically significant positive correlation between MNA and GOHAI scores (P < .01).

Regardless of the type of denture used, treatment of edentulous geriatric patients is important for improving nutritional status and self-rated oral health.

Several aspects of CKD differ significantly in the Eastern European nephrology community compared with Western Europe because of different geographic, socio-economic, infrastructure, cultural and educational features. The two most frequent aetiologies of CKD, DM and hypertension, and many other predisposing factors, are more frequent in the Eastern region, resulting in more prevalent CKD Stages 3-5. Interventions may minimize the potential drawbacks of the high prevalence of CKD in Eastern Europe, which include several options at various stages of the disease, such as raising public, medical personnel and healthcare authorities awareness; early detection by screening high-risk populations; preventing progression and CKD-related complications by training health professionals and patients; promoting transplantation or home dialysis as the preferred modality; disseminating and implementing guidelines and guided therapy and encouraging/supporting country-specific observational research as well as international collaborative projects. Specific ways to significantly impact CKD-related problems in every region of Europe through education, science and networking are collaboration with non-nephrology European societies who have a common interest in CKD and its associated complications, representation through an advisory role within nephrology via national nephrology societies, contributing to the training of local nephrologists and stimulating patient-oriented research. The latter is mandatory to identify country-specific kidney disease-related priorities. Active involvement of patients in this research via collaboration with the European Kidney Patient Federation or national patient federations is imperative to ensure that projects reflect specific patient needs.
Sleep disturbance and deficiency are common among older adults and have been linked with dementia and all-cause mortality. Using nationally representative data, we examine the relationship between sleep disturbance and deficiency and their risk for incident dementia and all-cause mortality among older adults.

The National Health and Aging Trends Study (NHATS) is a nationally-representative longitudinal study of Medicare beneficiaries in the US age 65 and older. Surveys that assessed sleep disturbance and duration were administered at baseline. We examined the relationship between sleep disturbance and deficiency and incident dementia and all-cause mortality over the following 5 years using Cox proportional hazards modeling, controlling for confounders.

Among the sample (n = 2,812), very short sleep duration (≤5 hours HR = 2.04, 95% CI 1.26 - 3.33) and sleep latency (>30 minutes HR = 1.45, 95% CI 1.03 - 2.03) were associated with incident dementia in adjusted Cox models. Difficulty maintaining alertness ("Some Days" HR = 1.
