A metodologia utilizada foi a pesquisa qualitativa e explorat?ria. Os dados foram coletados nos meses de fevereiro a abril de 2013, por meio de entrevistas individuais semiestruturadas, gravadas, transcritas, submetidas ? analise de conte?do do tipo tem?tica e discutidas ? luz de alguns estudiosos do assunto. Contou com a colabora??o de treze acad?micos de gradua??o em odontologia de uma institui??o p?blica de ensino dos Vales do Jequitinhonha e Mucuri. Em rela??o ? percep??o sobre sa?de coletiva, foi poss?vel identificar tr?s categorias: a sa?de coletiva como atendimento ? comunidade; a sa?de coletiva como preven??o e a sa?de coletiva como ?rea interdisciplinar. Quanto ? forma??o profissional, os acad?micos ressaltaram a dist?ncia entre a teoria apresentada no curso e a pr?tica no servi?o p?blico; bem como a estrutura curricular vigente, direcionando a forma??o para o consult?rio particular. Para alguns desses acad?micos, trabalhar no SUS est? associado a: oportunidade para adquirir experi?ncia e necessidade financeira; compromisso com a sa?de coletiva e articular o servi?o p?blico com o servi?o privado. E, para outros, o SUS n?o se apresenta como campo profissional. A pesquisa revela a necessidade de oferecer uma forma??o em sa?de coletiva estruturada a partir do cuidado coletivo com a sa?de, para que o aluno possa conhecer e refletir o que ? na atualidade a sa?de coletiva e o SUS, bem como o caminho que se faz atrav?s de integra??o efetiva entre ensino-servi?o, articulando pol?ticas de educa??o e pol?ticas de sa?de, adequando os novos egressos ?s necessidades sociais da popula??o. / Disserta??o (Mestrado) ? Programa de P?s-gradua??o em Ensino em Sa?de, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2013. / ABSTRACT The aim of the present study was to analyze the academic perception of dentistry students of public health care, the student?s professional education in the area of public health, and their perspective of working in the public health care system. A qualitative, exploratory and descriptive study was undertaken. Data was collected between the months of February and April 2013 through semi-structured individual interviews, which were recorded, transcribed, submitted to thematic analysis and discussed in the light of existing scientific literature on the object. A total of 13 dental students from the Public Education Instituition of Valeys Jequitinhonha e Mucur? participated in the study. In relation to public health three categories were identified: community health care; prevention based in public health care, and interdisciplinary public health care. With regard to professional education the students emphasized the gap between the theoretical formation in the course and the realities of the public health care system, and the course curriculum of the that directs the graduate towards private practice. For these students working in the public health system is associated with: the opportunity to acquire experience, financial necessity, a commitment to public health, and linking the public and private health care systems. For others the public health care system was not mentioned as a professional area. The study revealed the importance of offering professional education that considers the difficulties of working in the public health care system, integration between education and work, and of creating education and health policies that prepare newly graduated health professionals to address the social needs of the population.

Primeiramente ? feita uma segmenta??o baseada nas cores dos dentes e n?o dentes presentes na imagem atrav?s do uso de m?quina de vetores de suporte. A partir da identifica??o das regi?es de interesse, dentes e n?o dentes, os dados s?o representados de modo que a contagem, detec??o de fronteiras e classifica??o dos dentes possa ser feita. Para contagem e detec??o de fronteiras s?o utilizadas t?cnicas baseadas em operadores morfol?gicos, eros?o e transformada watershed, respectivamente. A classifica??o quanto aos tipos de dentes ? baseada na utiliza??o dos descritores de posi??o e forma, sendo esse ?ltimo definido por descritores de Fourier. O sistema portanto ? capaz de realizar a segmenta??o, a contagem e a classifica??o de dentes presentes nas imagens. / Several are the areas in which digital images are used in solving day-to-day problems. In medicine the use of computer systems have improved the diagnosis and medical interpretations. In dentistry it?s not different, increasingly procedures assisted by computers have support dentists in their tasks. Set in this context, an area of dentistry known as public oral health is responsible for diagnosis and oral health treatment of a population. To this end, oral visual inspections are held in order to obtain oral health status information of a given population. From this collection of information, also known as epidemiological survey, the dentist can plan and evaluate taken actions for the different problems identified. This procedure has limiting factors, such as a limited number of qualified professionals to perform these tasks, different diagnoses interpretations among other factors. Given this context came the ideia of using intelligent systems techniques in supporting carrying out these tasks. Thus, it was proposed in this paper the development of an intelligent system able to segment, count and classify teeth from occlusal intraoral digital photographic images. The proposed system makes combined use of machine learning techniques and digital image processing. We first carried out a color-based segmentation on regions of interest, teeth and non teeth, in the images through the use of Support Vector Machine. After identifying these regions were used techniques based on morphological operators such as erosion and transformed watershed for counting and detecting the boundaries of the teeth, respectively. With the border detection of teeth was possible to calculate the Fourier descriptors for their shape and the position descriptors. Then the teeth were classified according to their types through the use of the SVM from the method one-against-all used in multiclass problem. The multiclass classification problem has been approached in two different ways. In the first approach we have considered three class types: molar, premolar and non teeth, while the second approach were considered five class types: molar, premolar, canine, incisor and non teeth. The system presented a satisfactory performance in the segmenting, counting and classification of teeth present in the images.
