Effect of focal adhesion kinase inhibition on osteoblastic cells grown on titanium with different topographies

J. appl. oral sci; 28 (), 2020
Abstract Objective The present study aimed to investigate the participation of focal adhesion kinases (FAK) in interactions between osteoblastic cells and titanium (Ti) surfaces with three different topographies, namely, untreated (US), microstructured (MS), and nanostructured (NS). Methodology Osteo...

Effects of NSAIDs and environmental oxygen pressure on bone regeneration

J. oral res. (Impresa); 8 (2), 2019
Objective: To evaluate the effects of administering diclofenac and ketoprofen, as well as the effects of environmental oxygen pressure variation on mandibular bone regeneration. Methods: Thirty-six guinea pigs were distributed into two equal groups. Mandibular bone defects were performed on both groups. ...

Effect of risperidone on proliferation and apoptosis of MC3T3-E1 cells

Braz. j. med. biol. res; 52 (3), 2019
This aim of this study was to assess the molecular mechanism of osteoporosis in schizophrenia patients with risperidone use. Here, we investigated the effects of risperidone on cellular proliferation and apoptosis of a preosteoblast cell line, MC3T3-E1. Cell viability and apoptotic rate of MC3T3-E1 were ...

Necroptosis occurs in osteoblasts during tumor necrosis factor-α stimulation and caspase-8 inhibition

Braz. j. med. biol. res; 52 (1), 2019
Necroptosis is a regulated cell death mechanism. However, it is unknown whether necroptosis is involved in the death of tumor necrosis factor-α (TNF-α)-treated osteoblasts. Therefore, we conducted the study with TNF-α, Nec-1 (a specific inhibitor of necroptosis), and Z-IETD-FMK (a specific...

Addition of zirconium oxide to Biodentine increases radiopacity and does not alter its physicochemical and biological properties

J. appl. oral sci; 27 (), 2019
Abstract Objectives: To evaluate the radiopacity of Biodentine (BD) and BD associated with 15% calcium tungstate (BDCaWO4) or zirconium oxide (BDZrO2), by using conventional and digital radiography systems, and their physicochemical and biological properties. Materials and Methods: Radiopacity was eval...

Regulation of ghrelin receptor by microbial and inflammatory signals in human osteoblasts

Abstract: Recently, it has been suggested that the anti-inflammatory hormone ghrelin (GHRL) and its receptor GHS-R may play a pivotal role in periodontal health and diseases. However, their exact regulation and effects in periodontitis are not known. The aim of this in-vitro study was to investigate the ...

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-induce...

Short-term use of resveratrol in alloplastic graft material applied with calvarial bone defects in rats

Acta cir. bras; 34 (7), 2019
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: ...

Retinoic acid increases the effect of bone morphogenetic protein type 2 on osteogenic differentiation of human adipose-derived stem cells

J. appl. oral sci; 27 (), 2019
Abstract Bone morphogenetic protein type 2 (BMP-2) and retinoic acid (RA) are osteoinductive factors that stimulate endogenous mechanisms of bone repair which can be applied on management of osseous defects in oral and maxillofacial fields. Objective Considering the different results of RA on osteogene...

Stanozolol promotes osteogenic gene expression and apposition of bone mineral in vitro

J. appl. oral sci; 27 (), 2019
Abstract Stanozolol (ST) is a synthetic androgen with high anabolic potential. Although it is known that androgens play a positive role in bone metabolism, ST action on bone cells has not been sufficiently tested to support its clinical use for bone augmentation procedures. Objective: This study aimed to...
