Esta pesquisa teve como proposição verificar, por meio de um estudo epidemiológico, a distribuição do potencial hidrogeniônico da placa e de possíveis variáveis que o influenciam, em escolares de 14 anos, do sexo masculino. Foram coletadas informações sobre o potencial hidrogeniônico da placa em repouso e aos 5 e 20 minutos após um bochecho com solucão de sacarose a 10 por cento , a ingestão usual de alimentos, o índice de placa, os índices de cárie, as práticas preventivas relacionadas à saúde bucal e a ocupaçao e o nível educacional dos pais, ou responsáveis, dos escolares. Analisados os dados, pôde-se verificar que nas condições deste estudo não se observaram associações que permitissem detectar influências das variáveis estudadas em relação ao potencial hidrogeniônico da placa dentária. / This research has the purpose of investigating through an epidemiological study, the distribution of the hydrogenionic potential of the Plaque and the possibles variables which influence them in 14-year old schoolboys. Data on the hydrogenionic potential of the plaque were collected at rest and five and twenty minutes after having rinsed the mouth with a saccharose solution at 10 per cent . Data were also collected about usual ingestion of food, plaque rate, caries rates, preventive practices related to Buccal health, occupation and educational level of parents or adults responsible for the schoolboys. The analysis of the data made it evident that under the conditions of this study, no associations were observed that would allow for the detection of influences of the variables investigated in relation to the hydrogenionic potential of the dental plaque.

This thesis deals with a CAD programmed construction design of dental prosthetics and its subsequent production by means of a five axis machine tool. In the theoretical part of the thesis one can find characteristics and analysis of materials designed for a production of dental prosthetics constructions. Among other things, the practical part of the thesis follows up digitization of a patient´s oral cavity part with the use of Trios intraoral scanner representing the latest scanning technology. The obtained data created a basis for a design of the respective dental prosthetics construction using the shape dental system programme called DentalDesigner 2015. Furthermore, the paper deals with a production of a dental prosthetics construction by means of a five axis machine tool and pursues completion works which resulted in the prosthetics final shape. The paper is concluded with discussion comprising a summary of results acquired in the practical part beginning from dental implant introduction to insertion of the made prosthetics construction into the patient´s oral cavity.
