Feasibility and Outcomes of Temporary Bulbar Urethral Stent Placement After Internal Urethrotomy in the Largest Multicenter Series.

Background: Recent years have seen the development of a new generation of temporary urethral stents as an adjuvant option after direct vision internal urethrotomy (DVIU). Despite some early promising results, large series addressing their safety and outcomes are still lacking.

Objective: To report complications and outcomes from the largest series of patients receiving a temporary bulbar urethral stent to date.

Outcomes of COVID-19: Disparities by ethnicity.

Objectives: To investigate the role of ethnicity in COVID-19 outcome disparities in a cohort in Kuwait.

Methods: This is a retrospective analysis of 405 individuals infected with SARS-CoV-2 in Kuwait. Outcomes such as symptoms severity and mortality were considered.

The Effect of the Application Sequence of Casein Phosphopeptide-Amorphous Calcium Phosphate Paste on the Shear Bond Strength of Etch-and-Rinse Resin Cements to Dentin.

Purpose: To evaluate the effect of the application sequence of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste (MI paste) on shear bond strength (SBS) of 2 etch-and-rinse resin cements to dentin.

Materials And Methods: Sixty extracted human maxillary premolars were cut to expose the mid-coronal dentin surfaces. The teeth were randomly divided into 6 groups (n = 10), based on the resin cement used and CPP-ACP application.

Influence of Primers and Additional Resin Layer on Zirconia Repair Bond Strength.

Purpose: To evaluate the influence of alloy/zirconia primer and 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-containing resin layer treatments on the shear bond strength (SBS) of composite resin to zirconia after aging.

Materials And Methods: Sixty zirconia (Y-TZP) blocks were air-abraded (35-µm Al O ) and divided into 6 experimental groups (n = 10) in terms of primer/resin layer as follows: (1) control, without any primer or resin; (2) AP, Alloy Primer; (3) ZPP, Z-Prime Plus; (4) PL/ZPP, Z-Prime Plus with light polymerization; (5) AP+SEB, Alloy Primer along with light-cured bonding resin of a self-etch adhesive system (SE Bond); and (6) ZPP+SEB, Z-Prime Plus with SE Bond. After composite resin placement and light polymerization, the specimens were stored in distilled water (37°C for 4 months) and thermal-cycled for 6000 cycles.

A technique to ensure the reproducibility of a cast post and core.

The post-and-core pattern duplication technique is a simple, cost-effective, and accurate method of ensuring the reproducibility of a cast post and core. An acrylic resin pattern is fabricated for an endodontically treated tooth. The post portion of the pattern is duplicated with a polyvinyl siloxane impression material in the lower compartment of a container.

The influences of implant angulations in one and two directions on the retentive properties of overdenture attachments: an in vitro study.

Implant alignment is an important factor in overdentures retained by solitary abutments. In this study, the effect of implant angulations in two directions, on the amount of retention of attachments was evaluated. Ninety models were divided into nine groups of two blocks each; one for two implants and one for two attachments.

The effects of two attachment types on the stresses introduced to the mandibular residual ridge: a 3D finite element analysis.

Purpose: Two commonly used attachment systems for implant-retained overdentures are bar and ball systems. The aim of this study was to compare these two types of attachments on the basis of the stresses introduced to the mandibular posterior residual ridge by an overdenture retained by two implants.

Method And Materials: A basic model was generated from the data provided by a CT scan of a patient's mandible, the diagnostic casts, and the existing overdenture.

Thrombosis risk in carriers of the factor V Leiden mutation: is it associated with a defined skin color?

Factor V Leiden (FVL; G1691A) is an autosomal dominant mutation with a high risk for thrombosis. Speculation that founders of FVL lived in the Middle East is supported by a prevalence of FVL that is higher in Arabs residing in Israel, Jordan, Lebanon, and Syria (12-14%) than in other white populations like Europeans (4-5%, up to 15% in the South of Sweden). We sought to verify the appropriate use of skin color as a clinical sign by which Arab individuals in Kuwait are included or excluded from testing for FVL.

The prevalence of occlusal disharmony and its associated causes in complete dentures.

Aim: Occlusal disharmony is frequently observed among edentulous patients. With the side effects of occlusal disharmony in mind, the goal of this research was to investigate the prevalence of occlusal disharmony in inserted complete dentures and its associated causes.

Methods And Materials: This cross-sectional study was conducted on 107 selected patients.
