Evaluation of surgical cavities filled with three types of calcium sulfate.

Numai utilizatorii înregistrați pot traduce articole

The aim of this study was to evaluate histologically, three types of calcium sulfate - Merck (Brazil), Surgiplaster (Italy) and Capset (USA) - in surgically created defects on rabbit femurs. Twenty male New Zealand rabbits were used. Two surgical bone defects (5 mm diameter x 8 mm depth) were

Clinical and radiological evaluation of calcium sulfate as direct pulp capping material in primary teeth.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To evaluate the clinical and radiological response of primary molars to direct pulp capping with calcium sulfate hemihydrate. METHODS Forty primary molar teeth in 40 healthy children aged 5-9 years were treated by direct pulp capping. Teeth were randomly assigned to two groups (n=20)

Effect of repeated vertical loads on microleakage of IRM and calcium sulfate-based temporary fillings.

Numai utilizatorii înregistrați pot traduce articole

Temporary fillings are commonly used to seal endodontic access cavities between visits. IRM and Cavidentin were selected to represent two widely used groups of temporary filling materials. The first is a reinforced zinc oxide-eugenol preparation that is mixed at chairside, whereas the second is a

Calcium sulfate as a mandibular implant.

Mandibular reconstruction has posed significant problems, particularly when dealing with loss of mandibular substance. Various implant substances have been utilized in attempts to repair mandibular defects. These have included metals, synthetic material, and organic substances. All have posed

[Restoration of segmental bone defect by calcium sulfate pellet: experiment with rabbit].

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To compare the effects of different calcium sulfate pellets made by different methods in treating segmental defect of bone. METHODS Eighty New Zealand white rabbits underwent cutting off a segment in the middle part of radius so as to establish models of radial segmental defect, and than

Effect of calcium sulfate-chitosan composite: pellet on bone formation in bone defect.

Numai utilizatorii înregistrați pot traduce articole

The purpose of this experiment was to study the effects of chitosan, calcium sulfate, and calcium sulfate-chitosan composite pellet on the osteogenesis of defective tibia in rabbits. Eighty New Zealand white rabbits, each weighing approximately 3 to 3.5 kg, were used for this study. A 1-cm ostectomy

Comparison of the effect of hemihydrate calcium sulfate granules and Cerabone on dental socket preservation: An animal experiment.

Numai utilizatorii înregistrați pot traduce articole

Background. Early bone loss due to tooth extraction can be significantly reduced by socket preservation. The aim of this study was to compare the in vivo effects of hemihydrate calcium sulfate granules (an alloplastic material) and Cerabone (a bovine-derived xenograft) on socket preservation

Effect of adding resorbable calcium sulfate to grafting materials on early bone regeneration in osseous defects in rabbits.

Numai utilizatorii înregistrați pot traduce articole

This experiment was designed to study the osteogenic potential of adding medical-grade resorbable calcium sulfate mixture to grafting materials for filling osseous defects. Twelve New Zealand rabbits were divided into an active group of 10 animals and a control group of 2 animals. The median condyle

A comparative study of calcium sulfate artificial bone graft versus allograft in the reconstruction of bone defect after tumor curettage.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Cavity reconstruction after benign bone tumor removal is varied and controversial. Allograft is widely used but is associated with complications. New bone substitutes, such as calcium sulfate artificial bone, have been introduced for bone tumor operation. However, the bone healing

[Effect evaluation of medical calcium sulfate--OsteoSet in repairing jaw bone defect].

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To investigate the effectiveness of the medical calcium sulfate-OsteoSet bone graft substitute in the treatment of defect after excision of jaw cyst. METHODS Between December 2009 and May 2010, 15 cases of jaw cystic lesion were treated, including 9 males and 6 females with an average age

In vitro and in vivo efficacies of teicoplanin-loaded calcium sulfate for treatment of chronic methicillin-resistant Staphylococcus aureus osteomyelitis.

Numai utilizatorii înregistrați pot traduce articole

The in vitro and in vivo therapeutic efficacies of teicoplanin-loaded calcium sulfate (TCS; 10% [wt] teicoplanin) were investigated in a rabbit model of chronic methicillin-resistant Staphylococcus aureus (MRSA) osteomyelitis. The in vitro elution characteristics of teicoplanin from TCS pellets were

This study provides a facile method to map the microwave field distribution in a multimode microwave cavity. Anhydrous calcium sulfate powder was used to make the gypsum plates that were used as the carrying medium. Cobalt chloride hexahydrate, whose color changes when losing part or all of its

Bone repair process in calvarial defects using bioactive glass and calcium sulfate barrier.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To analyze bone repair process in Wistar rats' calvaria, with the use of two different biomaterials. METHODS Forty two male Wistar rats were used, and four bicortical cranial cavities were created in each animal. The cavities were filled with: bioactive glass (BG); calcium sulfate barrier

Engineering scaffolds integrated with calcium sulfate and oyster shell for enhanced bone tissue regeneration.

Numai utilizatorii înregistrați pot traduce articole

Engineering scaffolds combinging natural biomineral and artificially synthesized material hold promising potential for bone tissue regeneration. In this study, novel bioactive calcium sulfate/oyster shell (CS/OS) composites were prepared. Comparing to CS scaffold, the CS/OS composites with a
