Comparison of fracture strength, surface hardness, and color stain of conventionally fabricated, 3D printed, and CAD-CAM milled interim prosthodontic materials after thermocycling.

Purpose: The purpose of this study was to investigate the fracture resistance, surface hardness, and color stain of 3D printed, CAD-CAM milled, and conventional interim materials.

Materials And Methods: A total of 80 specimens were fabricated from auto polymerizing polymethyl methacrylate (PMMA), bis-acryl composite resin, CAD-CAM polymethyl methacrylate resin (milled), and 3D printed composite resin (printed) (n = 20). Forty of them were crown-shaped, on which fracture strength test was performed (n = 10).

Rectus Sheath Hematoma as a Complication in Patients With COVID-19: Clinical and Imaging Findings.

Objectives This study aims to investigate the frequency of rectus sheath hematoma (RSH), clinical findings, imaging findings, and prognosis in patients admitted to the hospital due to COVID-19. Methods In this retrospective study, the patient's demographic characteristics, known diseases, laboratory values, RSH-related symptoms, the treatment they received, imaging modality used to diagnose RSH, and side and size of RSH were recorded. In addition, the inpatient ward to which the patients were admitted, length of hospital stay, time from the beginning of anticoagulant use to the diagnosis of RSH, and prognosis were noted.

Shear bond strength of a self-adhesive resin cement to dentin surface treated with Nd:YAG and femtosecond lasers.

This study aims to evaluate the effect of Nd:YAG and femtosecond lasers irradiation on the shear bond strength (SBS) of a self-adhesive resin cement to the human dentin surface. One hundred extracted third molar teeth were randomly divided into 10 experimental groups according to dentin surface treatments; with and without the bonding agent, Nd:YAG 302 J/cm and 440 J/cm, femtosecond 4 J/cm and 7 J/cm, and control groups were prepared. After surface treatments, a self-adhesive resin cement was luted by using a bonding jig (Ultradent Products Inc.

Is routine abdominal ultrasonography necessary in macrosomic newborns with difficult delivery?

Adrenal hemorrhage is a relatively uncommon clinical problem of the newborn period. Clinical features of adrenal hemorrhage are variable. An abdominal mass, anemia, unexplained/persistent jaundice, bluish discoloration of the scrotum may be the presenting sign.

Diagnosis and percutaneous treatment of partial subclavian steal: Doppler ultrasonography and phase contrast magnetic resonance angiography findings and a brief review of the literature.

A 66-year-old woman presented with back pain and arm claudication. Severe stenosis of the left proximal subclavian artery was detected incidentally by thorax computed tomography. Doppler ultrasonography and phase contrast magnetic resonance angiography (PCMRA) evaluation revealed partial subclavian steal.
