A novel digital way to measure the vertical and horizontal dimensions of the supra-crestal peri-implant soft tissues.

Aim: To report on a novel digital superimposition workflow that enables measuring the supra-crestal peri-implant soft tissue dimensions all along implant treatment and afterwards.

Materials And Methods: A preoperative CBCT and intra-oral scans (IOS) are successively taken before surgery, at the end of the healing period, at prosthesis delivery, and over time; they are digitally superposed on a dedicated software. Then, the stereolithography files (STL) of the healing abutment, of the prosthetic abutment and the crown are successively merged into the superposition set of IOSs.

P-selectin inhibition reduces severity of acute experimental pancreatitis.

Background: Acute pancreatitis (AP) is characterized by disturbed pancreatic microcirculation with tissue necrosis. Platelet and leukocyte activation contributes to microcirculatory disorders and inflammatory tissue infiltration. P-selectin mediates the adhesion of both activated platelets and leukocytes to the vessel wall.

Adhesion of bonded orthodontic attachments to dental amalgam: In vitro study.

Bonding orthodontic attachments to molars is difficult in the presence of extensive buccal amalgam restorations. The purposes of this study were (1) to examine different amalgam surface preparations, (2) to examine properties of adhesive cements to amalgam, (3) to determine the most shear-resistant bonding technique and (4) to discuss whether these shear bond strengths were of adequate magnitude to be of clinical acceptability. The sample consisted of 108 standardized amalgam cylinders divided into 9 groups of 12 based on surface treatment technique and resin type.

Normal lung perfusion scan with extensive thromboembolic disease.

A 50-year-old woman with unexplained pulmonary hypertension had normal findings on six-view lung perfusion scan prior to open lung biopsy. The biopsy demonstrated old organized thrombi. The patient expired and autopsy disclosed extensive thromboembolic disease, both old and new.
