Graft application and dexamethasone treatment influences new bone formation in rat tibial bone defects

Int. j. morphol; 38 (5), 2020
SUMMARY: The objective of this study were bone defect complications that occur due to traumas or infections. Bone grafts are required to provide support, fill gaps and improve biological repair in skeletal damage. Dexamethasone plays role in calcium signaling modulation and used in diseases. Aim of this ...

The influence of Aloe vera with mesenchymal stem cells from dental pulp on bone regeneration: characterization and treatment of non-critical defects of the tibia in rats

J. appl. oral sci; 27 (), 2019
Abstract Objective This study aimed to evaluate the inflammatory effect and bone formation in sterile surgical failures after implantation of a collagen sponge with mesenchymal stem cells from human dental pulp (hDPSCs) and Aloe vera. Material and Methods Rattus norvegicus (n=75) were divided into fiv...

The effect of graft application and simvastatin treatment on tibial bone defect in rats. A histological and immunohistochemical study

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To evaluate histologically and immunohistochemically the bone regeneration after application of simvastatin on tibial bone defects in rats. Methods: Sixty Wistar albino rats were divided into 3 groups as control (6 mm tibial bone defect), defect + graft (allograft treatment), and def...

Action of a deproteinized xenogenic biomaterial in the process of bone repair in rats submitted to inhalation of cigarette smoke

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To investigate if the inorganic bovine bone matrix changes the bone formation in rats submitted to inhalation of cigarette smoke. Methods: Twenty Wistar rats were divided into two groups: Cigarette Clot Group (CCG), which in the inhalation chamber received the smoke of 10 cigarettes...

Daily melatonin administration improves osseointegration in pinealectomized rats

J. appl. oral sci; 26 (), 2018
Abstract The hypothesis of this study was that the peri-implant bone healing of the group of pinealectomized rats would differ from the control group. The samples were subjected to immunohistochemical, microtomographic (total porosity and connectivity density), and fluorochrome (mineralized surface) anal...

The effects of supplemental melatonin administration on the healing of bone defects in streptozotocin-induced diabetic rats

J. appl. oral sci; 24 (3), 2016
ABSTRACT Diabetes mellitus (DM) causes an increased production of free radicals that can impair bone healing. Melatonin is a hormone secreted mainly by the pineal gland, which participates in the neutralization process of free radicals. Objective The aim of this study was to investigate histologic and ...

Impact of micronutrients supplementation on bone repair around implants: microCT and counter-torque analysis in rats

J. appl. oral sci; 24 (1), 2016
ABSTRACT The use of natural substances and micronutritional approaches has been suggested as a therapeutic alternative to benefit the bone healing associated with no side effects. Nevertheless, the influence of micronutritional interventions with therapeutic proprieties on the bone repair has yet to be i...

Histomorphometric evaluation of strontium-containing nanostructured hydroxyapatite as bone substitute in sheep

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study is to evaluate the biocompatibility and osteoconductivity in surgical defects of sheep tibias filled with 1% strontium-containing nanostructured hydroxyapatite microspheres (SrHA), stoichiometric hydroxyapatite without strontium microspheres (HA), or blood clots. Santa Ines...
