This study evaluated the radiographic technical quality of preclinical and clinical root canal fillings (RCF) performed by undergraduate students on single-rooted teeth. Two independent calibrated endodontic specialists evaluated 94 preclinical radiographs (group 1) and 96 clinical radiographs (group 2). The apical length of each RCF was categorized as acceptable (0-2.0 mm short of the radiogra...
Background and purpose - Manipulation and cast immobilization is the primary management for diaphyseal forearm fractures in children, and re-displacement is the most common complication. We wanted (1) to analyze the incidence of re-displacement in a group of children treated with close reduction and casting; (2) to determine predictive factors such as demographics, mechanism of injury, affected...
BACKGROUND We analyzed the extent of the comminution in the acetabular weight-bearing area, the clinical and radiographic results, and the complications after a minimum 2-year follow-up of the modified Stoppa approach for the treatment of acetabular fractures, and we attempted to evaluate the efficacy of the operative technique. METHODS All of the 22 patients, who needed the anterior approach...
