Alveolar bone healing in rats: micro-CT, immunohistochemical and molecular analysis

J. appl. oral sci; 26 (), 2018
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 bon...

El esqueleto como órgano endocrino: funciones metabólicas de la osteocalcina
The skeleton as an endocrine organ: metabolic functions of osteocalcin

Actual. osteol; 13 (3), 2017
El esqueleto es uno de los sistemas más grandes de un vertebrado y, como tal, es razonable especular que no puede funcionar aislado del resto del organismo. De hecho, sabemos que existen sistemas complejos de regulación cruzada entre el esqueleto y muchos otros órganos. Hoy poseemos herramientas que n...

Effects of Syzygium aromaticum, Cinnamomum zeylanicum, and Salvia triloba extracts on proliferation and differentiation of dental pulp stem cells

J. appl. oral sci; 25 (5), 2017
Abstract Hypersensitivity, local irritative and cytotoxic effects are known for the chemical components of Syzygium aromaticum and Cinnamomum zeylanicum contained in dental materials. However, there is no intimate data in dentistry using the whole extracts of these plants and introducing new ones. Salvia...

Evaluación de la respuesta densitométrica en pacientes con osteoporosis posmenopáusica tratadas con ranelato de estroncio o denosumab
Densitometric response in postmenopausal osteoporosis treated with strontium ranelate or denosumab

Actual. osteol; 13 (1), 2017
Tanto el ranelato de estroncio (RSr) como el denosumab (Dmab) son eficaces en el tratamiento de la osteoporosis (OP) posmenopáusica (PM). El efecto de cada fármaco por separado sobre la densidad mineral ósea (DMO) ha sido estudiado recientemente. Con ambas drogas se observó, al año de tratamiento, u...

Marcadores de formación y resorción ósea y su utilidad para determinar el final del periodo de aposición ósea
Bone formation and resorption markers to evaluate the end of bone apposition

Actual. osteol; 13 (1), 2017
El pico de masa ósea (PMO) se alcanza entre los 20 y 35 años, pero la aposición ósea continúa hasta alcanzar el pico de fortaleza ósea (PFO). Se crea así una ventana entre ambos picos que podría ser evaluada mediante marcadores bioquímicos de recambio óseo, ya que durante dicho período la dens...

Short term sodium alendronate administration improves the peri-implant bone quality in osteoporotic animals

J. appl. oral sci; 25 (1), 2017
Abstract Sodium alendronate is a bisphosphonate drug that exerts antiresorptive action and is used to treat osteoporosis. Objective The aim of this study was to evaluate the bone repair process at the bone/implant interface of osteoporotic rats treated with sodium alendronate through the analysis of mi...

Osteogenic potential of periodontal ligament stem cells are unaffected after exposure to lipopolysaccharides

Abstract Periodontitis develops as a result of a continuous interaction between host cells and subgingival pathogenic bacteria. The periodontium has a limited capacity for regeneration, probably due to changes in periodontal ligament stem cells (PDLSCs) phenotype. The aim of this study was to evaluate th...

Primary Hyperparathyroidism: The Influence of Bone Marrow Adipose Tissue on Bone Loss and of Osteocalcin on Insulin Resistance

Clinics; 71 (8), 2016
OBJECTIVES: Bone marrow adipose tissue has been associated with low bone mineral density. However, no data exist regarding marrow adipose tissue in primary hyperparathyroidism, a disorder associated with bone loss in conditions of high bone turnover. The objective of the present study was to investigate ...

Efeito do tratamento periodontal nos níveis de osteocalcina sérica em pacientes com diabetes tipo 2 e periodontite crônica severa

O tecido ósseo é metabolicamente ativo e sofre um processo contínuo de renovação e remodelação. A osteocalcina é um peptídeo secretado pelos osteoblastos. Apesar de ser primariamente depositada na matriz óssea recém-formada, uma pequena fração entra em circulação na corrente sanguínea, se...
