Optimal Timeline and Hematoma Size Parameters for Middle Meningeal Artery Embolization in Acute-On-Chronic Subdural Hematomas.

Background And Purpose: Chronic subdural hematomas (cSDH) are subdural collection of blood for which the current treatment option remains as surgical evacuation due to recurring focal inflammation and angiogenesis. An adjunctive therapeutic intervention is endovascular embolization of the middle meningeal artery (MMA) to cease the prolific cycle of angiogenesis. Few investigations have been made into the indications of this treatment modality regarding the intervention timeline and hematoma size for non-surgical candidates with acute-on-chronic subdural hematomas.

A randomized clinical trial investigating the effect of three vital tooth bleaching protocols on oral health-related quality of life.

Objectives: This study aimed to compare changes in oral health-related quality of life (OHRQoL) resulting from three vital tooth bleaching protocols.

Methods: The participants (n = 105) were randomly assigned to one of three vital bleaching treatment groups: home bleaching (HB), in-office bleaching (IOB), or combined bleaching (CB). HB involved the use of custom-made trays and 10% carbamide peroxide for a 14-day treatment period.

The survey explored various aspects related to primary sources and prevention of disease exposure, dental management of suspected cases, impact of COVID-19 on students' clinical performance and effects of suspension of educational activities on academic performance and clinical competence.

Stress and behavioral changes with remote E-exams during the Covid-19 pandemic: A cross-sectional study among undergraduates of medical sciences.

Emergence of coronavirus disease 2019 (COVID-19) forced the worldwide higher educational institutes to adopt distance learning mode. Further, remote electronic exams (E-exams) were considered as mode of assessment. : This cross-sectional study evaluated the students' experience of remote E-exams during the COVID-19 pandemic among Medical Sciences students in Jordan.

COVID-19 and dental clinical practice: Students and clinical staff perceptions of health risks and educational impact.

Purpose/objectives: Due to the nature of the profession, dental healthcare workers are exposed to infectious diseases such as coronavirus disease 2019 (COVID-19), and the severity of the pandemic presents challenges to dental education institutions worldwide. This study investigated dental students and clinical staff perceptions of health risks and impacts on clinical competence of working in teaching clinics during the COVID-19 outbreak.

Methods: A 39-item survey composed of closed and open questions was sent to students and clinical staff of a prominent Australasian dental school.

Simulated clinical adjustment and intra-oral polishing of two translucent, monolithic zirconia dental ceramics: An in vitro investigation of surface roughness.

Objective: To assess the surface roughness and residual flaws in two translucent zirconia substrates following simulated clinical adjustment and intra-oral finishing/polishing.

Materials And Methods: Specimens were prepared from two translucent (5Y-ZP/8Y-ZP) and one conventional (3Y-TZP) zirconia substrates (n = 84 p/g). Arithmetic mean roughness parameter (R) was determined for all experimental groups at four stages (n = 21 p/g): (1) as-sintered, (2) surface grinding using a zirconia cutting diamond bur, (3) polishing using 1-step, 2-step or 4-step intra-oral polishing kits, and (4) laboratory polishing/glazing.

Post-fatigue fracture resistance of premolar teeth restored with endocrowns: An in vitro investigation.

Objectives: To evaluate the post-fatigue load-to-failure and failure modes of endodontically treated premolar teeth restored with endocrowns fabricated from different CAD/CAM materials.

Materials And Methods: A total of 60 extracted human, single-rooted premolar teeth were endodontically treated and sectioned horizontally 2 mm above the cementoenamel junction. Sectioned teeth were restored using two reconstruction designs: endocrowns (C) or post-crowns (C) (n = 30 p/g).

The Bacterial Microbiota of Gastrointestinal Cancers: Role in Cancer Pathogenesis and Therapeutic Perspectives.

The microbiota has an essential role in the pathogenesis of many gastrointestinal diseases including cancer. This effect is mediated through different mechanisms such as damaging DNA, activation of oncogenic pathways, production of carcinogenic metabolites, stimulation of chronic inflammation, and inhibition of antitumor immunity. Recently, the concept of "pharmacomicrobiomics" has emerged as a new field concerned with exploring the interplay between drugs and microbes.

The Windowed Removable Partial Denture: A Treatment Option for Patients with Lone-Standing Teeth.

The decision as to whether to retain or extract a single remaining natural tooth prior to the provision of dentures can be a difficult one. If the tooth is left in situ, the development of an adequate peripheral seal around the denture is not possible thereby compromising the appliance' retention. If the tooth is extracted the possibility of gaining direct retention with the use of clasps or attachments is lost.
