1. Beneficial effects of Cuscuta chinensis extract on glucocorticoid-induced osteoporosis through modulation of RANKL/OPG signals
Cuscuta chinensis Lam. (Convolvulaceae) is an important herbal medicine widely used to improve sexual function, treat osteoporosis, and prevent aging, and has been reported to exhibit anti-osteoporotic effects in vitro. However, the activity of Cuscuta chinensis Lam. on glucocorticoid-induced osteoporosis still remains unclear. The present study aimed to ass

3. Evaluation of Bone Repair in the Mandible of Rabbits Using Biphasic Calcium Phosphate Micro-Macroporous Hydroxyapatite Bioceramics and Beta-Tricalcium Phosphate
Abstract Objective: To perform a clinical and histological evaluation, characterizing and proving the feasibility of the use of beta tricalcium phosphate (HA/βTCP) bioceramics as a bone defect repair material, comparing it with autogenous bone and blood clot in terms of osteoinductive, conductive, and genic capacities. Material and Methods: The experiment

4. Short-term use of resveratrol in alloplastic graft material applied with calvarial bone defects in rats
Abstract Purpose: The effects of resveratrol administration on calvarial bone defects with alloplastic graft material was investigated for osteoinductive reaction and bone development in rats. Methods: Healthy male rats were randomly divided into 3 groups consisting of 10 rats. Groups were as follows: control (defect) group, defect + graft group, and defec

5. Effect of avocado/soybean unsaponifiables on periodontal repair in rats with arthritis and induced periodontitis
Abstract Objective: This study aimed to evaluate the effect of avocado/soybean unsaponifiables (ASU) on periodontal repair in rats with induced periodontitis and arthritis. Methodology: Forty-five rats were submitted to periodontitis induction by insertion of ligatures into the upper second molars, maintained for 15 days. These animals were randomly alloca

6. A comparative study of osteopontin and MMP-2 protein expression in peripheral and central giant cell granuloma of the jaw
Resumo Introdução: Os granulomas periféricos e centrais de células gigantes são lesões com etiologia e patogênese pouco conhecidas. Objetivo: Comparar a expressão das proteínas metaloproteinases da matriz-2 e osteopontina nas células gigantes multinucleadas e células mononucleares no granuloma periférico e central de células gigantes. Método

7. The effect of colchicine on alveolar bone loss in ligature-induced periodontitis
Abstract Colchicine is widely used in the treatment of several inflammatory diseases due to its anti-inflammatory effect, but effects on bone metabolism are unclear. The aim of this study was to evaluate the effects of systemically-administered colchicine on healthy periodontium and experimentally-induced periodontitis. In total, 42 male Wistar rats were inc

8. Effect of ProRoot MTA® and Biodentine® on osteoclastic differentiation and activity of mouse bone marrow macrophages
Abstract Objectives This investigation aimed to assess the differentiation inhibitory effects of ProRoot MTA® (PMTA) and Biodentine® (BIOD) on osteoclasts originated from murine bone marrow macrophages (BMMs) and compare these effects with those of alendronate (ALD). Materials and Methods Mouse BMMs were cultured to differentiate into osteoclasts with ma

9. A novel effect of geraniin on OPG/RANKL signaling in osteoblasts
In this study, the effects of geraniin on osteoprotegerin/receptor activator of nuclear factor-κB ligand(OPG/RANKL) in regulating the proliferation of osteoblasts and suppression of osteoclast-like cells (OLC) in OLC-osteoblast co-cultured system in vitro were investigated. Osteoblasts were cultured and identified with alkaline phosphatase (ALP), gomori sta

10. Effect of acute administration of nicotine and ethanol on tooth movement in rats
Abstract The aim of this study was to evaluate the effect of acute administration of nicotine and ethanol on tooth movement in rats. Two hundred rats were divided into eight groups: S: saline; N: nicotine; E: ethanol; NE: nicotine and ethanol; SM: saline with tooth movement; NM: nicotine with tooth movement; EM: ethanol with tooth movement; and NEM: nicotine

11. Systemic melatonin application increases bone formation in mandibular distraction osteogenesis
Abstract This study aimed to investigate the effects of different doses of systemic melatonin application on new bone formation during mandibular distraction osteogenesis (DO) in rats. Mandibular DO was performed on 30 adult female Sprague-Dawley rats, which were randomly divided into three groups: control group (CNT), melatonin dose 1 (MLT-D1), and melatoni

12. Up-regulated expression of CD147 gene in malignant bone tumor and the possible induction mechanism during osteoclast formation
It is increasingly evident that the microenvironment of bone can influence cancer phenotype in many ways that favor growth in bone. CD147, a transmembrane protein of the immunoglobulin (Ig) superfamily, was identified independently in different species and has many designations across different species. However, expression levels of CD147 mRNA in bone cancer
