Mandibular Kennedy Class I and maxillary Kennedy Class III presented the highest frequency in patients treated at the FO-UFF. These results are in agreement with previous studies that evaluated the different Kennedy classes in partially edentulous arches.

Após o movimento da reforma Sanitária no Brasil e a Implantação do Sistema Único de Saúde através da constituição de 1988, diversas mudanças foram observadas no cenário da saúde do país. Contudo, algumasescolas de Odontologia não acompanharam essas transformações, mantendo até então um currículo defasado. O presente estudo buscou analisar a percepçãodos alunos da Faculdade de Odontologia da Universidade Federal Fluminense (FOUFF) no ano de 2008 com relação à atual grade curricular. De um total de 102 estudantes, 43 (42,2%) acham ruim a atual grade curricular, enquanto 55 (53,9%) consideram boa, e apenas 4 (3,9%) consideram ótima. Já de um total de 111 alunos, 82 (73,9%) acreditam na necessidade de mudança do atual currículo oferecido pela Faculdade, enquanto apenas 2 (1,8%) não acham necessária a mudança e 27 (24,3%) não souberam opinar.

Purpose: The aim of this study was to evaluate the physical-mechanical properties of experimental orthodontic resins, containing different photoinitiators systems and photoactivated through a ceramic bracket, using a high irradiance and wide spectrum light emitting diode curing unit. Methods: Experimental resin composites (50:50 BisGMA/TEGDMA: 60% feldspar silanized particles) were formulated with different photoinitiators according to the following groups: phenylpropaneamine + amine DMAEMA (PPD), camphorquinone + amine DMAEMA (CQ) or bisacylphosphinic oxide (BAPO). A commercial orthodontic resin composite (Transbond XT) was used as control. The materials were then distributed into two groups, according to the photoactivation condition: directly or through a ceramic bracket, for 20s at 1200 mW/cm2. In the sequence, fifteen composite disks, 5mm of diameter and 1mm of thickness, were made for each of the eight groups. The degree of conversion (DC) was determined by means of Raman spectroscopy. Knoop hardness (KHN) was measured immediately after confection and after 24 hours of storage in 100% ethanol for indirect crosslink density (CLD) evaluation. Data were analyzed using two-way ANOVA followed by Tukey's test (α = 0.05). Results: The DC of the BAPO composite was significantly higher in comparison to the other materials, regardless of the photoactivation condition. The KHN was significantly different between the composite groups in the following sequence: BAPO> Transbond XT> CQ> PPD. The direct photoactivation presented higher KHN values, regardless the type of material. Regarding the CLD, there was statistical difference only for the material factor, as follow: PPD> BAPO = CQ = Transbond XT. Conclusion: The photoinitiator type and the photoactivation condition had a significant influence on the physical-mechanical properties of the evaluated materials.
