Methods: The analyses were performed in a scanning electronic microscope (JEOL, model JSM-5800 LV) with EDS system of microanalysis (energy dispersive spectroscopy). Results: The results showed that NiTi wires presented Ni and Ti as the main elements of the alloy with minimum differences in their composition. The CuNiTi wires, however, presented Ni and Ti with a significant percentage of copper (Cu). As for surface morphology, the wires that presented the lowest wire-surface roughness were the superelastic ones by Masel and Morelli, while those that presented the greatest wire-surface roughness were the CuNiTi 27 o C and 35 o C ones by Ormco, due to presence of microcavity formed as a result of pulling out some particles, possibly of NiTi. 4 The fracture surfaces presented characteristics of ductile fracture, with presence of microcavities. The superelastic wires by GAC and the CuNiTi 27 o C and the heat-activated ones by Unitek presented the smallest microcavities and the lowest wire-surface roughness with regard to fracture, while the CuNiTi 35 o C wires presented inadequate wire-surface roughness in the fracture region. Conclusion: CuNiTi 35 o C wires did not present better morphologic characteristics in comparison to the other wires with regard to surfaces and fracture region.

Methods: The tests were performed in an EMIC mechanical testing machine, model DL10000, capacity of 10 tons, at the Military Institute of Engineering (IME). Results: The results showed that, generally, heat-activated NiTi archwires presented slighter deactivation loadings in relation to superelastic. Among the archwires that presented deactivation loadings biologically more adequate are the heat-activated by GAC and by Unitek. Among the superelastic NiTi, the CuNiTi 27°C by Ormco were the ones that presented slighter deactivation loadings, being statistically (ANOVA) similar, to the ones presented by the heat-activated NiTi archwires by Unitek. When compared the CuNiTi 27°C and 35°C archwires, it was observed that the 27°C presented deactivation forces of, nearly, ⅓ of the presented by the 35°C. Conclusion: It was concluded that the CuNiTi 35°C archwires presented deactivation loadings biologically less favorable in relation to the other heat-activated NiTi archwires, associated to lower percentage of deformation, on the constant baselines of deactivation, showing less adequate mechanical behavior, under traction, in relation to the other archwires.

The sample consisted of 19 randomly selected patients in each group, as well as 20 individuals in the control group. All patients were treated during the prepubertal growth spurt for 12 months. Lateral cephalograms were analyzed at the beginning of active treatment and 12 months later. All data were tested with the ANOVA and Bonferroni tests. These tests showed that the twin block promotes a significant increase (P<.001) in the total length of the mandible, as well as an increase in anterior facial height. In contrast, ANB and NAPog were reduced. In both treatment groups, the maxillary incisors retruded significantly (P<.001), although more so in the twin block group. In the Thurow appliance group, the mandibular incisors protruded significantly (P<.001). All other differences between the two treated groups...

METHODS: The sample consisted of 138 students attending the last semester of 10 dental schools in the State of Rio de Janeiro/Brazil assessed by questionnaires with closed questions. They were presented with photographs and dental casts of a patient in the mixed dentition, with Angle Class II malocclusion, increased overjet and overbite, deviated dental midlines and anterior diastemas in the upper arch. RESULTS: It was found that students easily identified increased overjet (92% of students), followed by the presence of diastemas (89%), midline deviation (84.7%) and increased overbite (77.3%). Conversely, approximately half the sample (n=70 or 51% of the students) were able to identify bilateral Angle Class II malocclusion. Nearly all agreed on the need for treatment and that it should be provided by a specialist (n=131 or 95%), but found it difficult to determine the ideal moment to start orthodontic treatment: 48.9% of the sample would begin treatment at the end of the mixed dentition, 41.7% would indicate treatment during deciduous dentition and 7.9% during permanent dentition. CONCLUSIONS: On completion of their undergraduate courses, students encounter difficulties in diagnosing Class II and even find it hard to articulate ideas about a basic treatment protocol to correct this malocclusion.

Métodos: para quantificar essas modificações, foram mensuradas as áreas dos quadrantes labiais antes (T1) e após o tratamento (T2). Os lábios superiores e inferiores foram subdivididos em 4 quadrantes e as suas áreas foram medidas e expressas como percentagem da sua área total. A quantidade de correção da assimetria foi obtida calculando a diferença no percentual da área entre os quadrantes do lábio em T1 e T2. Resultados: os resultados demonstraram haver uma melhora significativa na assimetria observada inicialmente nestes pacientes do lado onde o desvio postural da mandíbula se apresentava.

The purpose of this case report was to present the diagnosis and treatment descriptions of a patient with an Angle Class II malocclusion complicated by tooth losses, severe dentoalveolar protrusion, and skeletal discrepancy. Treatment involved extraction of the maxillary first premolars, high-pull headgear to enhance anchorage, and high-pull J-hook headgear to retract and intrude the maxillary anterior segments. A successful outcome was achieved with traditional orthodontic treatment in this borderline surgical case. (Am J Orthod Dentofacial Orthop 2012;141:105-12)

Two hundred and eighty test samples were divided into 28 groups (n = 10), where 140 specimens were filled with Durafill micro-particulate resin and 140 with Charisma composite. In 140 samples, a coupling agent (silane) was applied. The surface treatment methods were: Phosphoric and hydrofluoric acid etching, sodium bicarbonate and aluminum oxide blasting, stone and burs. A Universal Instron Machine was used to apply an occlusal shear force directly to the resin composite bracket surface at a speed of 0.5 mm/min. The means were compared using analysis of variance and multivariate regression to assess the interaction between composites and surface treatment methods. Means and standard deviations for the groups were: Sodium bicarbonate jet 11.27 ± 2.78; burs 9.26 ± 3.01; stone 7.95 ± 3.67; aluminum oxide blasting 7.04 ± 3.21; phosphoric acid 5.82 ± 1.90; hydrofluoric acid 4.54 ± 2.87, and without treatment 2.75 ± 1.49. An increase of 1.94 MPa in shear bond strength was seen in Charisma groups. Silane agent application reduced the Charisma shear bond strength by 0.68 Mpa, but increased Durafill means for bicarbonate blasting (0.83), burs (0.98) and stone drilling (0.46). The sodium bicarbonate blasting, burs and stone drilling methods produced adequate shear bond strength and may be suitable for clinical use. The Charisma micro hybrid resin composite showed higher shear bond means than Durafill micro particle composite.
