1. Skeletal and nonskeletal consequences of hypoparathyroidism
ABSTRACT Hypoparathyroidism, despite the conventional therapy with calcium and active vitamin D, can lead to skeletal and nonskeletal abnormalities. Chronic hypoparathyroidism is associated with a significant reduction in bone remodeling, increases in areal and volumetric bone density, and improvement in trabecular microarchitecture and in trabecular bone sc

2. Update on trabecular bone score
ABSTRACT Trabecular bone score (TBS) is an indirect and noninvasive measure of bone quality. A low TBS indicates degraded bone microarchitecture, predicts osteoporotic fracture, and is partially independent of clinical risk factors and bone mineral density (BMD). There is substantial evidence supporting the use of TBS to assess vertebral, hip, and major oste

3. Radioprotective Effect of Sodium Selenite on Mandible of Irradiated Rats
Resumo O propósito deste estudo foi testar o efeito radioprotetor do selênio na microarquitetura óssea de mandíbulas de ratos irradiados. Quarenta ratos foram separados em 4 grupos com 10 animais: grupo controle (GC), grupo irradiado (GI), grupo selenito de sódio (SSG) e grupo selenito de sódio irradiado (SSIG). Uma dose única de 0,8 mg/kg de selenito

4. Swimming training potentiates the recovery of femoral neck strength in young diabetic rats under insulin therapy
OBJECTIVE: To test whether swimming training benefits femoral neck strength in young diabetic rats under insulin therapy. METHODS: A total of 60 male Wistar rats (age: 40 days) were divided equally into the following six groups: control sedentary, control exercise, diabetic sedentary, diabetic exercise, diabetic sedentary plus insulin and diabetic exercise

5. Undernutrition impairs the quality of growth plate and trabecular and cortical bones in growing rats
Abstract Purpose: To investigate the effects of dietary restriction on the growth plate and long bone tissue in growing rats. Methods: Sixty male Wistar rats were randomly assigned to two groups: Control (Con) and Diet-restricted (Res). After weaning, the Res rats were offered 50% of the chow ingested by the control (ad libitum food intake). The animals

6. ALVEOLAR BONE PATTERN AND SALIVARY LEPTIN LEVELS AMONG PREMENOPAUSAL OBESE WOMEN
RESUMO Racional: A perda óssea sistêmica pode levar à destruição periodontal mais severa, diminuindo a densidade mineral óssea local. Objetivo: Investigar as associações entre padrão ósseo alveolar, concentrações de leptina salivar e estado periodontal em mulheres obesas na pré-menopausa e eutróficas. Métodos: Foram avaliadas 30 mulheres co

7. Hyaluronic acid accelerates bone repair in human dental sockets: a randomized triple-blind clinical trial
Abstract This study evaluated the effects of hyaluronic acid (HA) on bone repair of human dental sockets. Thirty-two lower first premolars were extracted from 16 patients (2 per patient) for orthodontic reasons. Following the extractions, one socket was randomly filled with 1% HA gel, while the other was allowed to naturally fill with blood clot. After 30 an

8. Estructuras de titanio con gradiente de porosidad – fabricación por el método de partículas espaciadoras y caracterización
ABSTRACT It has proposed the use of porous titanium to reduce the problem of mechanical incompatibility, which occurs between such material used in implants and bone. The pores introduction in titanium decreases its elastic modulus by bringing it closer to that of both cortical and trabecular bones. This paper describes titanium fabrication by powder metallu

9. Obtención de compuesto de titanio con gradiente de porosidad mediante técnica pulvimetalúrgica
ABSTRACT Within the study of biomaterials for implantological use titanium is among the most widely employed metals due to its excellent corrosion and mechanical resistance. In spite of the advances made, there are some issues remaining with the value of the elastic moduli of the titanium (110GPa) in comparison with the elastic moduli of the cortical bone (2

10. Alveolar bone healing in rats: micro-CT, immunohistochemical and molecular analysis
Abstract Alveolar bone healing after upper incisor extraction in rats is a classical model of preclinical studies. The underlying morphometric, cellular and molecular mechanism, however, remains imprecise in a unique study. Objectives The aim of this study was therefore to characterize the alveolar bone healing after upper incisor extraction in rats by mic

11. Use of Micro-Computed Tomography for Bone Evaluation in Dentistry
Resumo A microtomografia computadorizada segue o mesmo princípio da tomografia computadorizada utilizada para avaliação dos pacientes, mas neste caso, é empregada para pequenas amostras com alta resolução. De forma não destrutiva, as amostras podem ser escaneadas, e cada fatia obtida é organizada de forma seriada para formar um volume tridimensional

12. To what extent does hyaluronic acid affect healing of xenografts? A histomorphometric study in a rabbit model
ABSTRACT Among the many graft materials that have been used for the treatment of bone defects in oral and maxillofacial regions is xenograft. To improve osteoconductive effects of xenografts, they have been combined with various biocompatible materials, such as hyaluronic acid and bone morphogenetic protein. Objective: To determine bone-healing capacity of
