Fixation of the short-term central venous catheter. A comparison of two techniques.

Purpose:: To compare the fixation of the central venous catheter (CVC) using two suture techniques.

Methods:: A clinical, analytical, interventional, longitudinal, prospective, controlled, single-blind and randomized study in adult, intensive care unit (ICU) patients. After admission and indication of CVC use, the patients were allocated to the Wing group (n = 35, catheter fixation with clamping wings and retainers) or Shoelace group (n = 35, catheter fixation using shoelace cross-tied sutures around the device).

The use of a biocompatible cement in endodontic surgery. A randomized clinical trial 1.

Purpose: To evaluate the clinical applicability of Pozzolana Biologic Silva cement (PBS(r)) in endodontic surgery.

Methods: Persistent apical periodontitis was diagnosed in 30 teeth of 12 patients by cone-beam computed tomography (CT). All patients had 2 or 4 affected teeth and underwent endodontic surgery with root-end filling.
