Background: This study aimed to compare the efficacy of resin composite for establishing a proper proximal contact in comparison to digital work flow Zirconia for restoration of endodontically treated teeth (ETT).
Material And Methods: Forty patients with posterior root canal treated teeth considering the inclusion and exclusion criteria were divided into two groups: half were restored by resin composite while the other received zirconia crown. Then, the proximal contact tightness (PCT) was measured via two methods: 1: VAS: the magnitude of felt PCT was recorded as a number between 0 to 10 (Visual Analogue Scale (VAS)). VAS direct and indirect as VAS-D, and VAS-I respectively. 2: Quantitative: using a custom-made force gage device to record the amount of force needed to pass a mounted dental floss through the proximal contact (Quantitative direct and indirect as Qn-D, and Qn-I respectively) those were compared with the PCT of natural teeth (NT). Data was compared with each other using Chi-square, Shapiro-Wilk, One Way ANOVA, Tukey Post Hoc, Linear regression, and Pearson tests (α= 0.05 in all tests).
Results: There were no significant difference between direct and in-direct groups regarding either sex of the patients (= 0.10), type of teeth (= 0.32), or jaw side (= 0.36). The VAS-D and VAS-I showed similar results in pairwise comparison (= 0.21). Moreover, both the Qn-D and Qn-I showed significantly higher PCT comparing to NT (= 0.45 and 0.0.0001 respectively) while the Qn-D and Qn-I were not distinguishable statistically (= 0.23). Furthermore, significant correlation was observed between VAS and quantitative methods for evaluation of PCT (Pearson value= 0.005).
Conclusions: Both the direct and in-direct restorations lead to clinically acceptable PCT, whilst indirect restorations showed slightly better results which was not statistically noticeable. Composite resins, Zirconium oxide, Digital Technology.

Background: Repetitive head impacts (RHI) from contact sports can lead to long-term white matter injury visualized on FLAIR scans as white matter hyperintensities (WMH). The goal of this study was to preliminarily characterize the unique pattern and features of WMH in middle aged- to older adults with remote history of exposure to RHI from contact sports.
Method: 76 participants (38 with substantial RHI, 38 with minimal or no RHI) from the Boston University Alzheimer's Disease Research Center had a FLAIR MRI during their annual study visit.
Three-dimensional architecture and linearized mapping of vibrissa follicle afferents.

Understanding vibrissal transduction has advanced by serial sectioning and identified afferent recordings, but afferent mapping onto the complex, encapsulated follicle remains unclear. Here, we reveal male rat C2 vibrissa follicle innervation through synchrotron X-ray phase contrast tomograms. Morphological analysis identified 5% superficial, ~32 % unmyelinated and 63% myelinated deep vibrissal nerve axons.

Aim: The aim of the study was to compare and evaluate proximal contact tightness and contours using two newer contact-forming systems in Class II composite restorations.
Materials And Methods: After institutional ethical approval and Clinical Trials Registry-India registration, patients were chosen according to the inclusion-exclusion criteria with informed consent. A total of 60 patients were randomly assigned to two groups.
Article Synopsis
- The "no-touch" technique allows for safe navigation of a guiding catheter during carotid artery stenting, especially in patients with complicated arterial lesions.
- A specially designed 4-Fr Newton-shaped catheter minimizes contact with stenotic lesions while advancing to the target area.
- In a study of eight procedures, this technique was successful in all cases, showing it can be effective for patients with tortuous anatomy and floating thrombi without causing complications.
Patellofemoral mechanics after uniplane open wedge high tibial osteotomy is superior to those after biplane open wedge high tibial osteotomy.

Background: It is known that open wedge high tibial osteotomy (OWHTO) may lead to progression of patellofemoral degeneration due to descent of the patellar height. However, the difference in patellofemoral joint (PFJ) loads with normal daily activity between uniplane and biplane osteotomies is unclear. The purpose of this study was to reveal the differences in PFJ biomechanics between uniplane and biplane OWHTO using finite element analysis (FEA).
