Preservation of dental sockets filled with composite bovine bone. A single-blind randomized clinical trial

Braz. dent. j; 29 (6), 2018
Abstract The purpose of this study was to evaluate the preservation of alveolar dimensions in human fresh extraction sockets filled with a composite bovine bone graft by means of design of single-blind randomized clinical trial. Forty participants had monoradicular teeth extracted (one teeth in each part...

Potencial of different hydroxyapatites as biomaterials in the bone remodeling

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To analyze the therapeutic potentials of different hydroxyapatites used for the correction of bone defects in rats. Methods: Forty rats, male, albino wistar, were distributed in 4 groups. They were submitted to a 3.5 mm defect in tibia. They received low purity hydroxyapatite, Stron...

Histomorphometric reference data of transiliac bone biopsy in children from 8 to 17 years old

Abstract: Background: Histomorphometric analysis of bone samples is a key tool for studying bone metabolism; however, only a few pediatric reference data exist. The aim of the present study is to report more reference data and to investigate if histomorphometric differences exist between age and gender...

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...

Oral implant osseointegration model in C57Bl/6 mice: microtomographic, histological, histomorphometric and molecular characterization

J. appl. oral sci; 26 (), 2018
Abstract Despite the successful clinical application of titanium (Ti) as a biomaterial, the exact cellular and molecular mechanisms responsible for Ti osseointegration remains unclear, especially because of the limited methodological tools available in this field. Objective: In this study, we present a ...

Bone turnover after bariatric surgery

ABSTRACT Objective The aim of the present study was to evaluate parameters of bone and mineral metabolism after bariatric surgery. Subjects and methods This sectional study included data from medical records from 61 bariatric surgery (BS) patients (minimum period of 6 months after the procedure) and ...

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...

Bone turnover markers in sheep and goat: A review of the scientific literature

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Bone turnover markers (BTMs) are product of bone cell activity and are generally divided in bone formation and bone resorption markers. The purpose of this review was to structure the available information on the use of BTMs in studies on small ruminants, especially for monitoring their variatio...

The role of daily physical activity and nutritional status on bone turnover in cystic fibrosis: a cross-sectional study

ABSTRACT Background Nutritional status and daily physical activity (PA) may be an excellent tool for the maintenance of bone health in patients with cystic fibrosis (CF). Objective To evaluate the relationship between nutritional status, daily physical activity and bone turnover in cystic fibrosis pati...
