Distribution of Trabecular Bone Density in the Maxilla and Mandible.

Introduction: Implant osseointegration is strongly influenced by the bone quality at the implant insertion site. The present work aims to create distribution diagrams showing the average bone density at each position within the jaws.

Materials And Methods: Data were retrospectively collected from 4 oral surgeons who sought bone-density measurements during implant placement using a torque-measuring implant micromotor.

Sinus lift with autologous bone alone or in addition to equine bone: an immunohistochemical study in man.

Purpose: The aim of the present study was to perform a comparative histological and immunohistochemical evaluation of microvessel density, vascular endothelial growth factor, and nitric oxide synthase (NOS) expression in sinus augmentation using autologous bone alone or in combination with equine bone.

Materials And Methods: Sixteen patients underwent sinus augmentation with autologous bone and a 50:50 mixture of autologous and equine bone. Control cores were harvested from preexisting nonaugmented bone under the sinus floor.

Vertical ridge augmentation using a flexible heterologous cortical bone sheet: three-year follow-up.

Rehabilitation of the atrophic alveolar ridge is often problematic. Bone augmentation surgery may be hindered by a lack of surfaces from which blood vessels can spread during the initial stages of bone regeneration. If heterologous biomaterials are used as an alternative to autologous bone grafts, the standard delivery formats-blocks or granules-both have significant limitations.

Alveolar ridge regeneration with equine spongy bone: a clinical, histological, and immunohistochemical case series.

Background: In the case of localized ridge atrophy, a ridge augmentation procedure, with the use of bone substitutes and barrier membranes, may then be necessary.

Purpose: The aim of the present study was a clinical, histological, and immunohistochemical evaluation of an equine spongy bone in alveolar ridge augmentation procedures.

Materials And Methods: Five patients showing horizontal mandibular ridge defects participated in this study.

Treatment of chemotherapy-induced oral mucositis with light-emitting diode.

Objective: The aim of this study was to assess the clinical effectiveness of phototherapy with noncoherent light in the alleviation of chemotherapy-induced mucositis in patients with metastatic cancer.

Background Data: Mucositis occurs in more than 40% of chemotherapy-treated patients, significantly reducing the quality of their lives. Many different interventions have been evaluated to reduce oral mucositis.

Familial hemiplegic migraine mutations increase Ca(2+) influx through single human CaV2.1 channels and decrease maximal CaV2.1 current density in neurons.

Insights into the pathogenesis of migraine with aura may be gained from a study of human Ca(V)2.1 channels containing mutations linked to familial hemiplegic migraine (FHM). Here, we extend the previous single-channel analysis to human Ca(V)2.
