[Use of Detravenol in treatment of chronic venous insufficiency of lower limbs].

Aim: The purpose of this study was to prove that Detravenol is not inferior by clinical efficacy to Detralex® in the course administration in patients presenting with chronic venous insufficiency of the lower extremities caused by lower limb varicose veins.

Patients And Methods: Ours was a prospective randomized open-liable comparative trial aimed at determining efficacy and safety of the two drugs in parallel groups with active control. The trial enrolled a total of 106 patients with chronic venous insufficiency of the lower extremities secondary to lower limb varicose veins.

The detection of vertical root fractures in post-core restored teeth with cone-beam CT: in vivo and ex vivo.

Objectives: To compare the accuracy of cone-beam CT and for the detection of artificially created large and small vertical root fractures in extracted teeth restored with post-core.

Methods: Individual metal cast post-cores were fixed in the root canals of 50 extracted single-rooted human teeth. In 30 teeth fractures were created by tapping posts with a hammer.

The accuracy of CBCT for the detection and diagnosis of vertical root fractures in vivo.

Aim: To compare the in vivo accuracy of CBCT for the detection of fracture lines versus the diagnosis of vertical root fractures (VRFs) according to characteristic patterns of associated bone resorption.

Methodology: Eighty-eight patients with symptoms typical of VRFs in root filled teeth, who underwent a CBCT examination and later had the teeth extracted, were divided into two groups: the fracture group (n = 65) and the control group (n = 23). Five blinded observers assessed the CBCT images in two sessions.

[Detection of vertical root fractures by cone beam CT].

The aim of the study was to assess the feasibility and precision of vertical root fracture diagnostics by cone beam CT (CBCT). Vertical root fractures were simulated in 25 sound teeth extracted because of orthodontic and periodontal reasons and examined by CBCT. The roots were then sectioned in corresponding planes and fractures were assessed microscopically.

Detection of artificially induced vertical root fractures of different widths by cone beam computed tomography in vitro and in vivo.

Aims: To compare the diagnostic accuracy of cone beam computed tomography (CBCT) for the detection of artificially induced vertical root fractures (VRFs) of different widths in vitro and in vivo.

Methodology: Vertical root fractures were induced in 25 extracted nonendodontically treated single-rooted human teeth (maxillary first premolars, maxillary canines and mandibular incisors). Twenty teeth without VRFs served as a control group.
