Comparative study of the effect of different temperatures on bovine bone used for bone repair of critical calvaria defects in rats.

To evaluate the osteoconductive potential of inorganic biomaterials of bovine origin submitted to different temperatures in the bone repair of critical defects in rat calvaria. Forty-eight rats were divided into four groups according to the material used to fill the defect: control group (GC), the defect was filled only with blood clot (n = 12); GBO, defect filled with Bio-Oss®, deproteinzed at 300°C (n = 12); GOX, defect filled with Inorganic GenOx®, deproteinzed from 850 to 1200°C (n = 12) and G700, defect filled with Inorganic GenOx 700, deproteinzed at 700°C (n = 12). In each animal's calvaria, a trephine bur with 5 mm internal diameter was used to produce a 6 mm-diameter central defect.

Successful Osseointegrated Implants in Hypertensive Patients: Retrospective Clinical Study.

Purpose: The aim of this study was to investigate the association of hypertension and antihypertensive drugs with the failure of osseointegrated dental implants.

Materials And Methods: This study conformed to STROBE Guidelines regarding retrospective studies. Data from 602 medical records of patients who received rehabilitation treatment with osseointegrated implants between 2000 and 2017, completed at least 6 months before the study, were analyzed.

Cervicofacial Necrotizing Fasciitis and Drugs.

Necrotizing fasciitis (NF) is a devastating disease that typically affects immunocompromised patients, chronically debilitated patients or drug users, but can also affect healthy patients. Necrotizing fasciitis can rapidly produce septic shock and requires immediate surgical management of the necrotic tissue. It is a bacterial infection that progresses rapidly and has a high mortality generally caused by aerobic and anaerobic bacteria.
