The comparison of the precision of different dental radiographic methods in mandibular peri-implantary measurements: an in vitro study.

Purpose: The objective of this in vitro study was to investigate and compare the precisions of several radiodiagnostic methods used in dentistry for the measurement of peri-implantary sites.

Materials And Methods: Six dental implants were placed in a human cadaver mandible. Periapical radiographs obtained with the parallel as well as the bisecting angle technique, digital and conventional panoramic radiographs were used for implant and peri-implant bone measurements.

Patients with anemia on admission who have undergone primary angioplasty for ST elevation myocardial infarction: in-hospital and long-term clinical outcomes.

Objective: We investigated the in-hospital and long-term follow-up (mean 21 months) results of patients with and without anemia on admission and who have undergone primary angioplasty for ST elevation myocardial infarction (STEMI).

Study Design: A total of 2509 patients (616 patients with anemia on admission, 1893 patients without anemia on admission), who were treated with primary angioplasty due to STEMI, were included in this study. Demographics and basic clinical features of the patients, outcomes of the primary angioplasty procedures, and clinical course of the patients during and a mean period of 21-month follow-up after hospitalization were retrospectively evaluated.
