Pré tratamento dentinário influência do condicionamento ácido, irradiação laser e hipermineralização na resistência ao cisalhamento de sistema adesivo multi uso

The disadvantages generated by the acid etching of the dentin, such as an increase in its permeability, in the surface moisture and in the potential to denature the external dentinal collagen, the formation of a fragility zone and the citotoxicity of the adhesive monomers; which are all aggravated by the depth of the dentin, have stimulated new and different treatment philosophies of the dentin. The purpose of the present study, therefore, was to investigate the effects of three dentin treatments: laser irradiation, acid etching and hypermineralization, in the shear bond strength of the SMP Plus bonding system. Sixty bovine incisors were extracted and randomly selected immediatly alter the animal's death. They were kept frozen (-18°C) for no longer than 14 days. After buccal dentinal surface had been exposed, X-Rays were taken to control the dentin thickness. The specimens were separated into two groups: (1) Control, kept in distilled water at 4ºC; (2) Mineralized, kept in hypermineralized solution at 4°C for 14 days. Each group was divided into three sub-groups according to the type of dentin treatment used: group F - followed the manufacturer instructions (acid-etching + primer + bond), group AL (acid-etching + primer + bond + laser) and group LA (laser + (laser + acid-etching + primer + bond). A composite resin standard cylinder (Z100-3M) was bond to the dentinal surface and the shear bond strength performed on a Universal lnstron machine 4301, with 500 Kg load and at 0,5mm/min. speed. The analysis of variance (ANOVA) determined that the treatments influenced the shear bond strength values (p<0,05) with the following average shearing load at failure: AL (9,96 MPa), F (7,28MPa) e LA (4,87 MPa). The interaction between the two factors analyzed Group (control and mineralized) and treatment (F, AL, LA) also influenced the shear bond strength (p<0,05). The highest values were obtained...

Desenvolvimento de sistema de análise para valerato de estradiol baseado em polímeros biomiméticos

Abstracts : The development of analytic methods more selective and sensitive is of great importance for a better quality in the determination of chemical species, therefore increasing the reliability of the results. In this way, the optimization of separation/concentration is still necessary. The use of Molecularly Imprinted Polymers - MIPs have demonstrated to be an efficient tool of analysis with a great potential in minimizing limitations of separation/concentration techniques traditionally employed. In general, the MIPs are obtained by polymerization in the presence of a template to be imprinted so that a polymeric skeleton is formed around the future analyte. In the present work, the template used is Estradiol Valerate (EV), compound used in the hormone replacement therapy (HRT) during climacteric. After the polymerization in bulk and in an anaerobic environment using MAA, EGDMA, AIBN, acetonitrile and VE, the obtained MIP was powdered, sifted (<120 μm) and placed in a soxhlet system containing ethanol at 60 °C, in order to remove the imprinted molecule through six successive washes in periods of 24 hours. The water used in the washings was analyzed using HPLC and spectrophotometry UV/Vis. Then, the obtained MIP was dried at room temperature and 150 mg was inset in SPE cartridges in order to evaluate the polymer's efficiency in the analyte pre-concentration and extraction. To do so, 100,0 mL of VE standard solution (2mg L-1) were pre-concentrated at 4,0 mL min-1 and eluted with 10,0 mL ethanol at 1,0 mL min-1, obtaining recoveries of 53%. Additionally, a NIP (non-imprinting polymer) was prepared to compare the obtained results, in which the recovery was 80%. In the same way, studies were conducted using commercial Strata™-X cartridges, obtaining 53% recovery. Since, the results did not reflect that than was expected, in relation with the MIP efficiency in the recovery, a computational ...

Parafunção severa: reabilitação oral com prótese total mandibular x overlay maxilar: relato de caso

In many oral rehabilitation professionals seeking venture renew people smile. However, these procedures have functional implications and aesthetic criteria which must be satisfied so that the final result is predictable. The restoration of relations intermaxillary, phonetics, masticatory function, esthetics and patient comfort are the goals to be achieved. An effective way to achieve these goals when immediate reconstruction with permanent dentures is not possible, make use of a type of partial denture called overlay. Bruxism is a manifestation of biopsychological imbalance that affects the stomatognathic system, characterized by clenching and / or attrition of teeth together so centric or eccentric, can be manifestation of nocturnal or diurnal. Its effects can manifest themselves in different parts of the stomatognathic system, varying the severity of the damage as the resistance of the structures affected, the time of existence, its regularity and the general state of the wearer. The description of the steps followed in solving this case, in which the patient edentulous mandibular arch while the maxillary arch showed absence of teeth 16 and 26 and, except for the teeth 17 and 27, all other teeth showed wear very sharp in the sense denoting incisal cervical, severe impairment of the vertical dimension, the quality of masticatory function and a marked impairment phonetic, this case report aims to guide the beginning of a rehabilitation, as well as the transitional phase of treatment for recovery of functional and aesthetic relationships intermaxillary .
