The aim of this study was to analyze through clinical and histomorphometric parameters the use of acellular dermal matrix (ADM) with or without mineralized bone allograft (AB) on bone formation in human alveoli after a 6- to 8-month healing period. A total of 19 patients in need of extraction of the maxillary anterior teeth were selected and randomly assigned to the test group (ADM plus AB) or ...

Enoxaparin sodium is a low-molecular-weight heparin. It is not clear whether the risk of development of osteoporosis after administration of low-molecular-weight heparins is lower than after administration of standard heparin. The aim of the present study was to investigate the effects of enoxaparin on histomorphometric parameters of bones in female Wistar rats (13-15 weeks old at the beginning...

PURPOSE To carry out a radiological and histomorphometric evaluation of bone response to two xenografts of animal origin, one porcine, and the other bovine, inserted in rabbits' tibiae. MATERIAL AND METHODS Twenty New Zealand rabbits weighing 3900-4500 g were used. Twenty bovine bone grafts (Endobon) in granulated form of 500-1000 μm granulometry were inserted in the proximal metaphyseal area...

The purpose of this study was to analyze the bone repair around commercially pure titanium implants with rough and porous surface, fabricated using powder metallurgy technique, after their insertion in tibiae of rabbits. Seven male rabbits were used. Each animal received 3 porous-surface implants in the left tibia and 3 rough-surface implants in the right tibia. The rabbits were sacrificed 4 we...

Aims: The aim of the current study is to evaluate effect Aloe Vera gel on healing process surgically made maxillary alveolar bone defects and new tissue formation in rabbits. Materials Methods: Twenty albino rabbits were randomly chosen conduct study, all selected inhabited under same circumstances involving ventilation, temperature, diet. Each rabbit received anesthetic solution separately und...

BACKGROUND Animal models of fracture consolidation are fundamental for the understanding of the biological process of bone repair in humans, but histological studies are rare and provide only qualitative results. The objective of this article is to present the histomorphometric study of the bone healing process using an experimental model of osteotomy in rabbit fibula without interference of sy...

This study aimed to evaluate the histological, histomorphometric and radiographic features of the bone repair in ovariectomized rats submitted to mandibular distraction osteogenesis. Thirty female Wistar rats were equally divided in ovariectomy and control group and submitted to mandibular distraction osteogenesis. After 7, 14 and 28 days the animals were sacrificed and mandibles were removed a...

OBJECTIVE(S) The adverse effects of pyridaben on reproductive system in male animals are not well established. This study was designed to elucidate how pyridaben can effects the histomorphometric, hormonal alternations and reproductive functions of BALB/c mice. Materials and Methods : For this study, 80 adult and apparently healthy male BALB/c mice were divided into three groups Viz, control, t...

BACKGROUND Following loss of teeth, atrophy of alveolar ridge of the jaws is a substantial problem and unintended outcome that compels clinicians to perform bone reconstruction ahead of implant placement. Although autogenous bone is recommended as the gold standard in bone reconstruction, aninvasive second surgery harvestinga limited volume of bone (from intraoral source) has led a significant ...
