2. Effect of DLC Films with and without Silver Nanoparticles Deposited On Titanium Alloy
Resumo O filme de carbono semelhante a diamante (DLC) é um material de revestimento duro e biocompatível que pode impedir a corrosão com liberação de íons metálicos. Este estudo avaliou as características estruturais do filme de DLC, com e sem nanopartículas de prata (Ag), depositadas por plasma (PECVD) em liga de titânio (Ti-6Al-4V) e formação �

3. Matriz porosa do BV60S associada a células osteoprogenitoras alógenas no tratamento de defeitos ósseos críticos em rádios de cães
RESUMO O objetivo do estudo foi avaliar o efeito da matriz porosa do biovidro 60S (BV60S) associada a células osteoprogenitoras (CO) alógenas no tratamento de defeitos ósseos críticos de cães. Foram utilizados 20 cães, machos, sem raça definida, com dois anos de idade e massa corporal média de 25kg. Com os cães sob anestesia geral, foram criados def

4. Digital radiography as an alternative method in the evaluation of bone density in uremic rats
RESUMO Introdução: A radiografia digital (RxD) pode representar uma alternativa adequada para investigar o distúrbio mineral e ósseo (DMO) e a perda de densidade óssea (DO) em modelos de roedores da doença renal crônica (DRC). O objetivo deste estudo foi utilizar a RxD para avaliar a DO em ratos com DRC, e avaliar a correlação entre os achados da R

5. Mineral composition, histomorphometry, and bone biomechanical properties are improved with probiotic, prebiotic, and symbiotic supplementation in rats chronically exposed to passive smoking: a randomized pre-clinical study
RESUMO: A fumaça de cigarro em grandes centros é uma das causas mais importantes de doenças inflamatórias crônicas em saúde pública e esta associada à diminuição de massa óssea, processo de consolidação e remodelação óssea. Os alimentos funcionais suplementados na dieta, devido sua capacidade de melhorar a absorção intestinal e competir co

6. 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

7. Bone callus formation is highly disrupted by dietary restriction in growing rats sustaining a femoral fracture
Abstract Purpose: To evaluate the effects of food restriction on fracture healing in growing rats. Methods: Sixty-eight male Wistar rats were assigned to two groups: (1) Control and (2) Dietary restriction. After weaning the dietary restricted animals were fed ad libitum for 42 days with 50% of the standard chow ingested by the control group. Subsequentl

8. Effects of hyperbaric oxygen treatment on implant osseointegration in experimental diabetes mellitus
Abstract Objective To evaluate whether hyperbaric oxygen (HBO) treatment has a favorable effect on implant osseointegration in diabetic rabbits. Material and Methods An experimental diabetes model was induced in 32 New Zealand rabbits through IV injection of alloxan. After the state of diabetes had been confirmed, one dental implant was placed in the met

9. Bioactive glass added to autogenous bone graft in maxillary sinus augmentation: a prospective histomorphometric, immunohistochemical, and bone graft resorption assessment
Abstract Objective The aim of this study was to compare the bone resorption rate, histomorphometry and immunohistochemical findings of bioactive glass (Biogran; Biomet, Warsaw, IN, USA) mixed with autogenous bone grafts (1:1) and autogenous bone graft isolate in maxillary sinus elevation surgery. Material and Methods A total of 9 maxillary sinuses were gra

10. Osteointegration of porous absorbable bone substitutes: A systematic review of the literature
Biomaterials’ structural characteristics and the addition of osteoinductors influence the osteointegration capacity of bone substitutes. This study aims to identify the characteristics of porous and resorbable bone substitutes that influence new bone formation. An Internet search for studies reporting new bone formation rates in bone defects filled with po

11. Effects of avocado/soybean unsaponifiables (ASU) on the treatment of ligature-induced periodontitis in rats
Abstract The purpose of this study is to evaluate the effect of the avocado/soybean unsaponifiables (ASU) on the treatment of induced periodontitis in rats. Periodontitis was induced in 84 rats via ligature placement around the second upper molar, which was removed after 7 days, and scaling and root planning (SRP) was performed at this time. Subsequently, th

12. Hepatic Osteodystrophy: The Mechanism of Bone Loss in Hepatocellular Disease and the Effects of Pamidronate Treatment
OBJECTIVES: The present study was designed to evaluate the bone phenotypes and mechanisms involved in bone disorders associated with hepatic osteodystrophy. Hepatocellular disease was induced by carbon tetrachloride (CCl4). In addition, the effects of disodium pamidronate on bone tissue were evaluated. METHODS: The study included 4 groups of 15 mice: a) C
