PURPOSE The purpose of this report was to evaluate the effect of the fabrication method and material type on the fracture strength of provisional crowns. MATERIALS AND METHODS A master model with one crown (maxillary left second premolar) was manufactured from Cr-Co alloy. The master model was scanned, and the data set was transferred to a CAD/CAM unit (Yenamak D50, Yenadent Ltd, Istanbul, Tu...

We report the case of a 43-year-old man who sustained a head injury with left frontal hematoma after being hit by a falling steel plate. He had persistent left shoulder pain but plain film could not clearly demonstrate the suspected scapular fracture, which was finally confirmed by 3-dimensional (3D) reconstructed computed tomography (CT). With the presence of fractures at the base of the corac...

Background and Aim: Different methods and materials are available for post and core (P&C) fabrication. We aimed to compare the fracture resistance and failure modes of endodontically treated maxillary central incisors restored with six different P&C systems. Materials and Methods: In this in-vitro study, after endodontic treatment and coronal preparation of 60 maxillary central incisors, six d...

We report an 85-year-old woman with an L3 vertebral body fracture who presented with back pain, bilateral leg pain, and weakness after four months of conservative treatment. Because of unstable pseudoarthrosis, the L3 vertebral body collapsed in the standing position and the L3 nerve root was compressed. The indicated surgery decompressed the L3-L4 foramen and fused the unstable segment. The ba...

This paper characterizes the fracture toughness of layer-by-layer (LBL) manufactured thin films with elastic polyurethane, a tough polymer, and poly(acrylic acid) as a stiffening agent. A single-edge-notch tension (SENT) specimen is used to study mode I crack propagation as a function of applied loading. Experimental results for the full-field time histories of the strain maps in the fracturing...

Background Adolescent athletes are a high-risk population for stress fractures. We report four cases of stress fractures of the second proximal phalanx, which had not been previously diagnosed as the location of the stress fracture of the foot, in teenage athletes. Case report All fractures were on the plantar side of the proximal phalangeal base, and the oblique images of the plain radiograp...

This article describes 2 cases of osteochondroma emanating from the posterior aspect of the femoral neck with a fracture at the base of its stalk caused by impingement between the tumor and the ischium. A 44-year-old man and a 57-year-old man presented with left hip pain. Radiographs revealed a mass at the posterior aspect of the femoral neck. Computed tomography and magnetic resonance imaging ...

OBJECTIVE To investigate the influence of the use of a rollator walking aid on assessment of gait and mobility. DESIGN Prospective, longitudinal study. SUBJECTS Geriatric patients during inpatient rehabilitation (n=109; mean age 83.1 years). METHODS Assessment at the beginning and prior to discharge from rehabilitation using: gait-analysis (GAITRite®, speed, cadence, stride-time, stride-l...

introduction: skull-based osteomyelitis is bony infection which generally originates from inadequately treated chronic infection, adjoining tissue infection or after trauma.case: 11 month female child had a trivial fall while standing near a bucket. the child developed fracture of right clavicle and left orbital swelling which was inadequately treated. this resulted in in spread of infection to...
