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 movem...

Bone repair access of BoneCeramic™ in 5-mm defects: study on rat calvaria

J. appl. oral sci; 26 (), 2018
Abstract Objective: The aim of this study was to evaluate the osteoconductive potential of BoneCeramic™ on bone healing in rat calvaria 5-mm defects. Material and Methods: A 5-mm calvaria bone defect was induced in three groups and the defect was not filled with biomaterial [Clot Group (CG)], aut...

Alveolar bone healing in rats: micro-CT, immunohistochemical and molecular analysis

J. appl. oral sci; 26 (), 2018
Abstract Alveolar bone healing after upper incisor extraction in rats is a classical model of preclinical studies. The underlying morphometric, cellular and molecular mechanism, however, remains imprecise in a unique study. Objectives The aim of this study was therefore to characterize the alveolar bon...

Effects of triethylene glycol dimethacrylate (TEGDMA) on the odontoclastic differentiation ability of human dental pulp cells

J. appl. oral sci; 25 (6), 2017
Abstract Objectives: The primary purpose of this study was to examine the effects of triethylene glycol dimethacrylate (TEGDMA) on odontoclastic differentiation in the dental pulp tissue. Material and Methods: The effects of different TEGDMA dosages on the odontoclastic differentiation capability of de...

Hepatic Osteodystrophy: The Mechanism of Bone Loss in Hepatocellular Disease and the Effects of Pamidronate Treatment

Clinics; 72 (4), 2017
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. ...

Imunomarcação para TRAP em tecido de reparação óssea de ratos espontaneamente hipertensos (SHR) tratados com Atenolol

Introdução: A hipertensão arterial tem sido um dos maiores problemas de saúde no mundo, com grandes alterações para as doenças cardiovasculares e renais. O tecido ósseo tem função importante no suporte, proteção e locomoção e está sob o controle de fatores sistêmicos como hormônios e fat...

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 plan...

Relationship between hypertension and periapical lesion: an in vitro and in vivo study

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to compare potential aspects of periapical lesion formation in hypertensive and normotensive conditions using hypertensive (BPH/2J) and wild-type control (BPN/3J) mice. The mandibular first molars of both strains had their dental pulp exposed. At day 21 the mice were eu...

Effects of alveolar bone displacement with segmental osteotomy: micro-CT and histomorphometric analysis in rats

Braz. oral res. (Online); 30 (1), 2016
Abstract The purpose of this study was to evaluate the effects of segmental osteotomy on the blood vessels and osteoclasts in rats using micro-computed tomography (micro-CT) and histomorphometric analysis. After segmental osteotomy was performed around the maxillary first molars of 36 male Sprague-Dawley...

Flavonoids isolated from Tridax procumbens (TPF) inhibit osteoclasts differentiation and bone resorption

Biol. Res; 48 (), 2015
BACKGROUND: The Tridax procumbens flavonoids (TPF), are well known for their medicinal properties among local natives. The TPF are traditionally used for dropsy, anaemia, arthritis, gout, asthma, ulcer, piles, and urinary problems. It also used in treating gastric problems, body pain, and rheumatic pains...
