2. Dormancy overcoming and germination test in Piptadenia stipulacea (Benth.) Ducke seeds
RESUMO Piptadenia stipulacea (Benth.) Ducke apresenta germinação lenta e desuniforme, devido à dormência tegumentar, além disto, não há indicações padronizadas quanto à temperatura e substrato para condução do teste de germinação em laboratório. Objetivou-se avaliar métodos de superação de dormência, temperaturas e substratos na germinaç�

4. Effect of hydrofluoric acid concentration and etching time on resin-bond strength to different glass ceramics
Abstract: The objective of this study was to evaluate the effect of the hydrofluoridric acid (HF) concentration and time of acid conditioning on bond strength of three glass ceramics to a resin cement. Thus, fifty blocks (10 mm x 5 mm x 2 mm) of each ceramic (LDCAD: IPS e.max CAD; LCAD: IPS Empress CAD and LDHP: IPS e.max Press) were made and embedded in acr

5. Influence of ethanol-wet dentin, adhesive mode of application, and aging on bond strength of universal adhesive
Abstract The aim of this study was to evaluate the effect of ethanol on the bond longevity of a universal adhesive system to bovine dentin, under different modes of adhesive application and artificial aging. Bovine dentin was exposed, and the smear layer was standardized by sandpaper polishing. Specimens were randomly divided into 2 groups: ethanol (E) and n

6. Métodosdesuperaçãodedormênciadesementesde Flamboyant / Methods of overcoming seed dormancy flamboyant
The Flamboyant (Delonix regia (Bojer ex Hook) Raf.) is an exotic ornamental species adapted to the conditions of the Brazilian territory, belonging to subfamily Caesalpinioideae and it has seeds with hard coat that promotes seed dormancy caused by the impermeability of seed coat to water and oxygen. The aim of this study was to test different types of mechan

7. Quantitative analysis of S. mutans and S. sobrinus cultivated independently and adhered to polished orthodontic composite resins
In Orthodontics, fixed appliances placed in the oral cavity are colonized by microorganisms. OBJECTIVE: The purpose of this study was to quantitatively determine the independent bacterial colonization of S. mutans and S. sobrinus in orthodontic composite resins. MATERIAL AND METHODS: Seven orthodontic composite adhesives for bonding brackets were selected an

8. Avaliação do substrato dentinário irradiado com laser de Er:YAG : resistência de união, padrão de fratura e análise ultramorfológica / Evaluation of dentin irradiated with Er:YAG laser : bond strength, failure pattern and ultramorphology analysis
The Er:YAG laser has been widely used in Dentistry and because its ability to remove mineralized dental tissues, it is indicate to be used in Operative Dentistry. As the Er:YAG laser is recent, little is known about the consequences of dental tissues irradiation and their effects on adhesive restorative procedures. Thus, the objectives of this study were to

9. Influência da contaminação do campo operatório na resistência de união à dentina / Influence of the contamination of the operatory Field at dentin bonding strength
Studies on contamination are difficult to compare due to the variety of experimental designs as the type of substrate, the time when contamination takes place during the adhesive procedure and how this contamination is treated in order to clean the operatory field. Thus, further studies are needed to investigate more thoroughly the conditions described in th

12. Streptococcus mutans attachment on a cast titanium surface
This study examined by means of scanning electron microscopy (SEM), the attachment of Streptococcus mutans and the corrosion of cast commercially pure titanium, used in dental dentures. The sample discs were cast in commercially pure titanium using the vacuum-pressure machine (Rematitan System). The surfaces of each metal were ground and polished with sandpa
