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.

A Micro-computed Tomography Analysis of Marginal and Internal Fit of Endocrowns Fabricated from Three CAD/CAM Materials.

Objective: To assess the marginal and internal misfit of endocrowns fabricated from a resin matrix ceramic (CS), a partially crystallized (EMC), and a fully crystallized (ILS) lithium disilicate glass-ceramic.

Methods And Materials: Thirty human premolar teeth restored with endocrowns were investigated. Three CAD/CAM materials were used (n=10 per group): CS, EMC, and ILS.

Color Changes Associated with Sandblasting, Hydrofluoric Acid Etching, and Er:YAG Laser Irradiation of Milled Feldspathic Porcelain Laminate Veneers.

Objectives: To evaluate color changes in milled feldspathic porcelain laminate veneers following hydrofluoric acid etching (HFA), sandblasting (SB), or Er:YAG laser irradiation (LI).

Methods And Materials: Disc-shaped specimens (thickness=1 mm, diameter=8 mm) were milled from feldspathic porcelain blocks (n=40). Glazed specimens were randomly assigned to four subgroups (n=10 each) according to surface treatment: negative control, HFA, SB, and LI.

Neurosyphilis in disguise.

Purpose: Neurosyphilis can mimic different diseases, not only in its clinical presentation but also on imaging. Treponema pallidum is also known as the "great imitator." Having an ultimate diagnosis of neurosyphilis is quite critical as this can affect management drastically.
