introduction: the aim of this study was to compare centering ability and dentin removal of three rotary systems in curved root canals of extracted teeth. materials and methods: sixty root canals of mandibular first molars with curvatures ranging between 25-35 o were divided into three groups of 20 teeth each. based on pre-instrumentation radiographs that assessed the angle and the radius of can...

Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tub...

background: connective tissue attachment following periodontal regenerative surgery is directly related to the attachment of fibrin clot on to the root surface during early wound healing events. the adhesion of fibrin clot to the root surface affected by periodontal disease depends on the biologic acceptance of the root surface which can be accomplished by various root conditioning procedures d...

INTRODUCTION Oval-shaped canals represent a challenge for rotary nickel-titanium (NiTi) files because buccal and/or lingual recesses are commonly left uninstrumented. The aim of the present study was to evaluate the debridement quality of the Self-Adjusting File (SAF) system in oval canals and compare it with the debridement achieved by a commonly used NiTi rotary system. METHODS A careful sp...

conclusions prp dressing could significantly decrease the depth and surface area of dfus in a three-week period. background some of the studies confirmed the effectiveness of platelet rich plasma (prp) in the treatment of diabetic foot ulcers (dfu). however, these studies had small sample size and used different methods such as prp gel or prp injections. the results are also contraversial. obje...

Recognition of aberrant root canal configurations is critical to successfully negotiate and treat a one such aberrancies C shape system. The fins webs present in system presents challenge debridement obturation. Knowledge variations through advanced imaging modalities like CBCT, rotary hand instruments assisted with ultrasonics modified obturation techniques aid effective management shaped cana...

T he process of debridement is an important step in the preparation of the wound bed in chronic wounds. Ways in which wound debridement can be achieved include surgical, sharp, mechanical, enzymatic and autolytic debridement. Expert opinion and clinical experience suggest that removal of the material such as necrotic tissue and fibrinous slough from the surface of a wound is necessary for the p...

The debridement treatments of dental implants are very important in longterm maintenance after implant placement in a patient. Deposition of periodontal pathogens around the implant surface has a high risk of causing periimplantitis. The aim of this study was to evaluate the extent of elimination of Porphyromonas gingivalis, known as representative periodontopathic bacteria, from titanium, whic...

abstract introduction: scaling and root planing is one of the most commonly used procedures during periodontal treatments. removal of calculus using conventional hand instruments is incomplete and rather time consuming. to find more efficient and less difficult instrumentation method, investigators have proposed lasers as an alternative or adjunct to hand instruments for scaling and root planin...
