bacterial colonization on coated and uncoated orthodontic wires:a prospective clinical trial

Clinical, Salivary and Bacterial Markers on the Orthodontic Treatment

Inhibition of restenosis in femoropopliteal arteries: paclitaxel-coated versus uncoated balloon: femoral paclitaxel randomized pilot trial.

BACKGROUND The success of percutaneous intervention in peripheral arterial disease is limited by restenosis. The aim of the present pilot study was to evaluate a novel method of local drug delivery. METHODS AND RESULTS This randomized multicenter study with blinded reading enrolled 87 patients in Rutherford class 1 to 4 with occlusion or hemodynamically relevant stenosis, restenosis, or in-st...

effect of postoperative amoxicillin on early bacterial colonization of peri-implant sulcus: a randomized controlled clinical trial

objectives: with side effects of antibiotics taken into consideration, the necessity of antibiotic therapy after simple implant placement procedures is still a subject of debate and the existing literature on this topic is widely controversial. the aim of this study was to assess the effect of postoperative amoxicillin therapy on early colonization of peri-implant sulcus after implant placement...

Comparison of survival time between two types of orthodontic fixed retainer: a prospective randomized clinical trial

BACKGROUND The aim of this prospective clinical study was to compare the mean durability and the failure rates of two types of orthodontic retainers. METHODS Orthodontic patients (142) aged between 14 and 28 years were recruited in this study. The polyethylene woven ribbon (Ribbond, Seattle, WA, USA) retainer was compared with a 0.0175-in flexible spiral wire (Respond, Ormco, Glendora, CA, US...

Prospective randomized clinical trial to compare pain levels associated with 2 orthodontic fixed bracket systems.

INTRODUCTION In this randomized clinical trial, we compared pain levels associated with 2 fixed appliance systems during initial orthodontic tooth movement. METHODS Sixty-six patients (36 female, 30 male) were randomly allocated to either a conventional twin bracket (Tru Straight, Ormco Europe, Amersfoort, The Netherlands) or a self-ligating bracket (Damon 3, Ormco). Both arches were bonded, ...

Antibiotic coated catheter to decrease infection: pilot study.

BACKGROUND AND OBJECTIVES Nosocomial catheter related bloodstream infections (CR-BSI) increase morbidity and mortality in critically ill patients. Central venous catheters (CVC) coated with rifampin and minocycline (RM) decrease rates of colonization and CR-BSI. However, recent trials challenged the clinical impact of such catheters. We designed this trial to compare rates of colonization and C...
