1. Effect of a novel bioceramic root canal sealer on the angiogenesis-enhancing potential of assorted human odontogenic stem cells compared with principal tricalcium silicate-based cements
Abstract Objective: This study evaluated the angiogenesis-enhancing potential of a tricalcium silicate-based mineral trioxide aggregate (ProRoot MTA), Biodentine, and a novel bioceramic root canal sealer (Well-Root ST) in human dental pulp stem cells (hDPSCs), human periodontal ligament stem cells (hPLSCs), and human tooth germ stem cells (hTGSCs). Methodo

2. Effect of EDTA on TGF-β1 released from the dentin matrix and its influence on dental pulp stem cell migration
Abstract: Bioactive molecules stored in dentin, such as transforming growth factor beta1 (TGF-b1), may be involved in the signaling events related to dental tissue repair. The authors conducted an in vitro evaluation of the amount of TGF-b1 released from dentin slices after treatment with 10% ethylenediaminetetraacetic acid (EDTA), 2.5% sodium hypochlorite (

3. Inflammatory response of human dental pulp to at-home and in-office tooth bleaching
ABSTRACT Tooth bleaching is a technique of choice to obtain a harmonious smile, but bleaching agents may damage the dental pulp. Objective: This study evaluated the inflammatory responses of human dental pulp after the use of two bleaching techniques. Material and Methods: Pulp samples were collected from human third molars extracted for orthodontic reason

4. Combined therapy with mineral trioxide aggregate, and guided tissue regeneration for a large radicular cyst: a 13-year follow-up
Biomaterials such as membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. A combination of apical surgery and these biomaterials is one of the latest treatment options for avoiding tooth extraction. In case of periapical lesions, guided tissue regeneration (GTR) is attempted to improve the self-regenerative healing pr

5. Influência do tamanho das bases ósseas apicais no apinhamento dentário / Relationship of apical base length and dental crowding
The influence of many factors on dental crowding has been studied since long time ago, mainly in its relationship with anterior lower crowding. But, the influence of the apical bases length on the dental crowding was still not clarified. As there are evidences in the literature, it was decided to carry out the present study to investigate the relationship be

6. Mechanisms underlying the differentiation of stem cells from human exfoliated deciduous teeth (SHED) into odontoblasts and endothelial cells / Mecanismos envolvidos na diferenciação de células-tronco de dentes decíduos exfoliados humanos (SHED) em odontoblastos e células endoteliais
Dental pulp tissue engineering aims to replace the inflamed or necrotic pulp by a healthy and functionally competent tissue able to form new dentin in order to repair lost structure. The purposes of this work were: to evaluate the differentiation ability of stem cells from human exfoliated deciduous teeth (SHED) into functional odontoblasts, showing the form

7. Efeito do peróxido de carbamida a 16% na mucosa oral de ratos diabéticos e não diabéticos / Effects of 16% carbamide peroxide in the oral mucosa of diabetic and non diabetic rats
Purpose: to evaluate the effects of the application of 16% carbamide peroxide in the oral mucosa of diabetic and non diabetic rats. Methods: we studied 30 young, male and adult Wistar albino rats, 15 diabetics induced by streptozotocin, and 15 non diabetics. The animals were divided in 6 groups: NDC(non diabetic control), NDIP(non diabetic immediately peroxi

8. Transmigration of mandibular second premolar in a patient with cleft lip and palate: case report
Disturbances involving abnormalities in tooth eruption are named ectopia. Transmigration is the name assigned to ectopia in the presence of teeth in areas distant from the alveolar process. Initial angulation of the tooth bud of the second premolar and premature loss of permanent mandibular 1st molars can influence the distal migration of the second premolar

9. Fibroblast cell population kinetics in the mouse molar periodontal ligament and tooth eruption.
Fibroblast cell population kinetics in the developing molar periodontal ligament was investigated in 10, 12, 16 and 20 days old mice by autoradiography after the administration of [3H]thymidine. Labelled mitoses, in number per unit area, were counted over the apical zones of the sections and percentage labelled mitoses (PLM) curves were drawn. Median values

10. On the incremental lines in human dentine as revealed by tetracycline labeling.
Growth of human dentine was investigated in extracted permanent teeth exhibiting more than two tetracycline lines. It was concluded that: (1) The secretory activity of an odontoblast varies considerably during its life cycle, and likewise the rate of migration of the odontoblast cell body varies. Odontoblast secretion and migration as a general rule start sl

11. An autoradiographical study of [3H]thymidine incorporation into subcutaneously transplanted mouse molar teeth. Cell proliferation and migration in transplanted teeth.
Mice bearing either allografts or isografts of 10 day old molar teeth were injected with [3H]thymidine to identify proliferating and migrating cells within the graft and surrounding tissues. In isografts proliferating cells were found successively in the area underlying the cervix, in the cervical pulp and the coronal pulp. However, cells did not migrate fro

12. Fibroblast cell proliferation in the mouse molar periodontal ligament.
Cytogenesis of the developing molar periodontal ligament was studied by determining labelling indices in 4 groups of young mice. Autoradiographs were made using paraffin sections of demineralised specimens from 10 days, 12 days, 16 days and 20 days old mice allowed to survive a varying period (1--96 hours) after the administration of [3H]thymidine.
