1. Low-intensity pulsed ultrasound promotes tissue regeneration in rat dental follicle cells in a porous ceramic scaffold
Abstract The aim of this study was to investigate the effects of low-intensity pulsed ultrasound (LIPUS) on the osteogenic differentiation of dental follicle cells (DFCs) in vitro and on the regenerative effects of DFC-OsteoBoneTM complexes in vivo. DFCs were isolated and characterized. In the in vitro study, DFCs were cultured in an osteogenic medium in the

2. Hyperplastic dental follicle: case report
RESUMO O folículo pericoronário caracteriza-se como uma área radiolúcida em volta de um dente incluso. Acredita-se que esses folículos podem originar cistos e tumores. O objetivo deste trabalho foi relatar o caso clínico de um paciente do gênero feminino, 15 anos de idade, normossistêmica, que apresentava folículo pericoronário aumentado, envolvend

3. Avaliação do tamanho da imagem radiográfica do folículo do germe de incisivos centrais superiores permanentes / Assessment of the size of the radiographic image of permanent upper central incisors dental follicle
Ao entender o desenvolvimento do folículo dental, conhecemos a normalidade, diagnosticamos possíveis alterações, e realizamos o tratamento adequado. Os objetivos foram avaliar: o tamanho e comportamento da imagem radiográfica do folículo do germe de incisivos centrais superiores permanentes e estimar os valores máximos da distância e da área para ca

4. Distribuição de MT1-MMP na região odontogenica de incisivos inferiores de ratos em condições funcionais de erupção normal e alterada : estudo imunohistoquimico / MT1-MMP distribuiton in the odontogenic region of lower incisors in rats with normal and altered eruption : an immunohistochemical study
Matrix metalloproteinases (MMPs) are a growing family of endopeptidases that are capable of degrading many structural components of the extracellular matrix, including collagen. MMPs on the dental follicle may be related with remodelation that occurs in this tissue during dental eruption. MT1-MMP has been considered an important membrane-type matrix metallop

5. Imunolocalização de CSF-1, OPG e RANKL no periodonto relacionado ao esmalte de incisivos de ratos em erupção normal e contida / Immunolocalization of CSF-1, OPG and RANKL in the enamel-related periodontium of rat incisors in normal and immobilized eruption
In the rat incisors the face of the socket related to the enamel is resorpted continually on the inner side and formed on the outer side. A study accomplished at our laboratory showed that in rat incisors immobilized by a period of 18 days, there is a replacement of bone resorption in the face of the socket related to the enamel by bone formation, where oste

6. Primary failure of tooth eruption associated with secondarily inflamed dental follicle: inflammatory follicular cyst?
A falha primária de erupção é caracterizada pelo não irrompimento de um dente sem que haja impedimento mecânico ou que o dente esteja em posição anormal ou devido à causas sistêmicas. É um fenômeno raro e não foi associado com alterações do folículo dentário. Este relato descreve um caso de falha primária de erupção de um primeiro molar i

7. CorrelaÃÃo dos aspectos radiogrÃficos e morfolÃgicos de folÃculos pericoronÃrios e terceiros molares com rizogÃnese incompleta / Correlation between the radiographic and morphological features of the dental follicle of unerupted third molars with incomplete root formation
The objective of this research was to determinate the correlation between the radiographic and morphological features of the dental follicle of unerupted third molars with incomplete root formation. To accomplish that, one cross sectional study was done, with 56 patients (105 teeth) from 13 to 24 years of age. The panoramic radiograph was used to determine i

8. A histological study of the innervation of developing mouse teeth.
The innervation of developing mouse teeth between initial formation and crown formation was investigated using silver-stained serial sections. The developing innervation correlated with the stage of development of individual teeth rather than the chronological age of the mice. Nerves approached the developing dental papilla during the bud stage and formed a

9. Parathyroid hormone-related protein induces spontaneous osteoclast formation via a paracrine cascade
Experiments in vivo have established that tooth eruption fails in the absence of parathyroid hormone (PTH)-related protein (PTHrP) action in the microenvironment of the tooth because of the failure of osteoclastic bone resorption on the coronal tooth surface to form an eruption pathway. To elucidate the effects of PTHrP on osteoclast regulation in this envir

10. Changing expression of intermediate filaments in fibroblasts and cementoblasts of the developing periodontal ligament of the rat molar tooth.
The distributing of vimentin and cytokeratin intermediate filaments within the cells of the dental follicle and developing periodontal ligament is described during eruption of the rat 1st molar tooth. Alcohol-fixed tissues from animals ranging from neonates to 12 wk old were cryosectioned, immunolabelled with monoclonal antibodies against vimentin and a rang

11. The role of transforming growth factor alpha in rat craniofacial development and chondrogenesis.
To explore the possible role of transforming growth factor alpha (TGF-alpha) in craniofacial development, its expression in the craniofacial region of rat embryos from embryonic day (d) 9 to d 20 was examined by in situ hybridisation and immunostaining. The TGF-alpha transcripts were first detected in the neural fold of embryonic d 9 and 10 embryos. In the c
