A investigação de plantas medicinais é indispensável na busca de novas substâncias com potencial atividade ansiolítica e antidepressiva, visto que a ansiedade e depressão estão entre os distúrbios do sistema nervoso central (SNC) mais relevantes dentre os problemas de saúde mundial. Tais plantas são fontes de óleos essenciais (OE) que frequentemente são utilizados na aromaterapia, pois fornecem substâncias voláteis capazes de curar e prevenir doenças por meio da inalação. Esta prática já se mostrou efetiva sobre o SNC, trazendo benefícios terapêuticos a pacientes que não respondiam bem aos tratamentos convencionais. Uma espécie vegetal cujo OE possui atividade sobre o SNC é o Citrus aurantium L. (laranja amarga), espécie do gênero que mostrou atividade ansiolítica quando utilizado na aromatização de ambiente na sala de espera de um consultório dentário. Aqui avaliamos o potencial efeito ansiolítico e antidepressivo do OE de Citrus aurantium L por via inalatória em camundongos, por meio da resposta comportamental em modelos experimentais de ansiedade, o Labirinto em Cruz Elevado, e de depressão, o Teste do Nado Forçado. Com esta avaliação, o OE não foi efetivo por via inalatória em nenhuma das concentrações testadas (0,5%, 1,0% e 2,5%), tanto para ansiedade quanto para depressão. No entanto, este resultado não exclui a possibilidade de obtenção de tais efeitos se alterada a concentração de OE

This study is a literature review about promotion of oral health in babies and it discusses the importance of early preventive treatment. The conclusions are: 1 - The early treatment aims to reduce the dental caries prevalence in babies and to make familiar the dentistry´s office. It is important the creation of oral habits in children and in their parents. 2 - The high prevalence of dental caries in babies shows the necessity of programs with health promotion in the first infancy. The aim is to keep the oral health of these children. 3 - The success of the oral health promotion in babies depends on the awareness of the parents about the importance of oral hygiene. This fact must be considered during the planning and development of programs to this age.

The aim of the present study was to point out the importance of the experience of undergraduate dental students in extra-curricular activities and volunteer work, as a means through which to gain essential knowledge and abilities for their professional lives. A literature review of the Medline, Scielo, and Lilacs databases was carried out in an attempt to select articles related to the university extension and volunteer work of undergraduate dental students. It is still extremely difficult to include university extension and volunteer work as an important activity in Dentistry courses. However, the presentday work market demands professionals who have expertise not only in dental techniques, but also in the socio-cultural characteristics of communities, considering that people need to be comprehensive in their psychosocial aspects in order to be treated as a complete professional. Therefore, university dentistry courses should give equal consideration to both oral rehabilitation skills and the promotion of general healthcare, acquired mainly through extracurricular activities, in an attempt to redeem the integral education of the healthcare professional. Moreover, students should pay closer attention to the opportunities offered during their undergraduate courses, as the work market for dentists is becoming more and more competitive. Moreover, the dentist whose professional life is limited to the dental office will most certainly forgo the opportunity to act in other social areas as well as the recognition that comes with such acts.

Since bleaching has become a popular procedure, the effect of peroxides on dental hard tissues is of great interest in research. Purpose: The aim of this in vitro study was to perform a qualitative analysis of the human enamel after the application of in-office bleaching agents, using Scanning Electron Microscopy (SEM). Materials and Methods: Twenty intact human third molars extracted for orthodontic reasons were randomly divided into four groups (n=5) treated as follows: G1- storage in artificial saliva (control group); G2- four 30-minute applications of 35% carbamide peroxide (total exposure: 2h); G3- four 2-hour exposures to 35% carbamide peroxide (total exposure: 8h); G4- two applications of 35% hydrogen peroxide, which was light-activated with halogen lamp at 700mW/cm2 during 7min and remained in contact with enamel for 20min (total exposure: 40min). All bleaching treatments adopted in this study followed the application protocols advised by manufacturers. Evaluation of groups submitted to 35% carbamide peroxide was carried out after two time intervals (30 minutes and 2 hours per session), following the extreme situations recommended by the manufacturer. Specimens were prepared for SEM analysis performing gold sputter coating under vacuum and were examined using 15kV at 500x and 2000x magnification. Results: Morphological alterations on the enamel surface were similarly detected after bleaching with either 35% carbamide peroxide or 35% hydrogen peroxide. Surface porosities were characteristic of an erosive process that took place on human enamel. Depression areas, including the formation of craters, and exposure of enamel rods could also be detected. Conclusion: Bleaching effects on enamel morphology were randomly distributed throughout enamel surface and various degrees of enamel damage could be noticed. Clinical significance: In-office bleaching materials may adversely affect enamel morphology and therefore should be used with caution.
