Objectives: The purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (DEC) could accelerate the amount of orthodontic tooth movement (OTM) in young adult mixed breed dogs. Methods: Fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. Orthodontic force...

BACKGROUND CONTEXT Magnetic resonance imaging (MRI) is commonly used to assess patients with lumbar spinal stenosis. No single MRI sequence has been shown to be superior in spinal canal measurements. There are also cost concerns for the increased clinical and research use of MRI. Using only a single sequence may lower the financial burden; however, this requires spinal canal measurements in bot...

The purpose of this study is to evaluate calcium hydroxide as a root canal dressing in presence apical lesion due pulpal necrosis, after chemomechanical preparation. Culture test were done 19 patients wich 80% all teeth treated with remained negative and 100% PMCC. Under the present experimental conditions, PMCC well mantained desinfection status pursued during preparation therefore indicated a...

This study evaluated the efficacy of 2 types of rotary instruments employed in association with sodium hypochlorite (NaOCl) or EDTA in removing calcium hydroxide (CH) residues from root canals dentin walls. Forty-two mandibular human incisors were instrumented with the ProTaper System up to F2 instrument, irrigated with 2.5% NaOCl followed by 17% EDTA and filled with a CH intracanal dressing. A...

introduction: root canal treatment is based on elimination of intraradicular microorganisms. calcium hydroxide ca(oh) 2 is the most widely used material for canal dressing, however, enterococcus faecalis has been reported to be resistant bacteria in persistent apical periodontitis . the purpose of this study was to evaluate the efficacy of ca(oh) 2 on the elimination of intraluminal and intratu...

objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics. cone beam computed tomography (cbct)  has significantly enhanced image quality compared to digital radiography (dr) and greatly aids the diagnosis of vrfs but, metal artifacts has remained as a problem in vrf detection.  this study evaluated the effect of intra canal posts on the diagnostic accuracy of cbct and d...
