Peri-implantitis or Periimplantitis is characterized as an inflammatory reaction that affects the hard and soft tissue, which results in loss of supporting bone and pocket formation surrounding the functioning osseointegrated implant. This review aimed to evaluate the effectiveness of surgical and non-surgical treatment of peri-implantitis. The data sources used was PubMed. Searches of this dat...

Inflammatory infiltrate may be important in the evolution of inflammatory processes involving peri-implant tissues. Angiogenesis is an important feature of inflammation and healing, but its role in the development and progression or in the healing of periodontal lesions has not been elucidated. Vascular endothelial growth factor (VEGF) is a potent inducer of endothelial cell proliferation. The ...

OBJECTIVES Most studies that clinically validated peri-ictal SPECT in intractable partial epilepsy had used technetium-99m-hexamethylpropylene amine oxime (99mTc-HMPAO or 99mTc-exametazime) as the radiopharmaceutical. Because of some theoretical advantages, technetium-99m-ethyl cysteinate diethylester (99mTc-ECD or 99mTc-bicisate) is increasingly being used instead. This study compares unstabil...

Rats have an attenuated febrile response to endogenous pyrogen near the term of pregnancy. Given the fundamental role of E-series prostaglandins (PGEs) in mediating the febrile response to blood-borne endogenous pyrogen, the present experiments were carried out to determine whether PGEs increase in the area surrounding the organum vasculosum laminae terminalis (peri-OVLT) of near-term pregnant ...

Dental implants have become a widely used dental treatment approach. It is important to identify factors that can be detrimental to dental implants and the peri-implant complex. There is controversy regarding whether occlusion plays a role in the implant and peri-implant condition. The present study aims to review the scientific literature regarding this topic. Animal and human studies, and pre...

The poor prognosis for patients with glioblastoma (GB) heightens the importance of maintaining function throughout treatment. Hyperglycemia has been linked to poor neurological outcomes following stroke, traumatic brain and spinal cord injury. We hypothesized this may also be true following the resection of GB. We assessed associations with post-operative function with the goal of identifying m...

PURPOSE The aim of this study was to examine whether a previous peri-implantitis site can affect osseointegration, by comparing implant placement at a site where peri-implantitis was present and at a normal bone site. A second aim of this study was to identify the tissue and bone reaction after treating the contaminated implant surface to determine the optimal treatment for peri-implant disease...

BACKGROUND Recent evidence suggests that application of the Revised Cardiac Risk Index (RCRI) for peri-operative cardiovascular risk stratification in vascular surgery patients may be inappropriate, necessitating the development of risk indices specific to vascular surgery patients. OBJECTIVES To identify risk factors for cardiovascular morbidity and mortality in South African patients underg...
