Adequação de recursos humanos ao PSF: percepção de formandos de dois modelos de formação acadêmica em odontologia The Family Health Program (FHP) and human resources: perceptions of students from two different dentistry schools

O Programa Saúde da Família - PSF foi instituído pelo governo federal objetivando reverter o modelo assistencial. Os recursos humanos envolvidos devem estar preparados para alcançar os objetivos que o PSF propõe. O propósito desse artigo foi avaliar os desejos, percepções e preparo de acadêmicos de Odontologia, em relação aos princípios do PSF, de duas diferentes Faculdades de Odontologia, aqui denominadas Faculdades 1 e 2. Buscou-se ainda analisar se as faculdades tiveram potencial transformador sobre os acadêmicos, graduando-os com compromisso social e sensibilidade humanitária, considerados importantes para aqueles que querem trabalhar no PSF. Questionários individuais foram aplicados por um único pesquisador. As respostas foram analisadas pelo programa Epi-Info. Os resultados mostraram que prevalece entre os acadêmicos o desejo de trabalhar no PSF por razões ligadas às dificuldades do mercado de trabalho e os mesmos citam freqüentemente a técnica como a principal característica necessária a um dentista para que o mesmo atue no PSF. Por outro lado, diferenças estatisticamente significativas foram encontradas entre os acadêmicos, apontando uma provável influência do Estágio Supervisionado, ministrado sob a forma de internato rural, sobre a formação do acadêmico da Faculdade 1, possivelmente habilitando-o melhor para o PSF.<br>The purpose of this study was to evaluate the perceptions and opinions of dental students from two different Dentistry Schools in Brazil, both known here as Dentistry Schools 1 and 2 about the Family Health Program - FHP. The study analyzed if the Dentistry Schools had any influence on the students, graduating professionals with humanitarian and social sensibility, which are considered very important prerequisites for those who wish to work on this governmental health program, as well as searching for professional expectation of the students. Individual questionnaires were applied by only one researcher among the students who took part in the study. Answers were analysed by the Epi-Info program and results showed that difficulties related to the job market may be influencing students to join the FHP. Results also reveal that students consider technician an important prerequisite for dentists who wish to work on this governmental program. Significant statistical differences between the students were found: those who were graduating in Dentistry School 1 seemed more adequate to FHP and the reason for this difference may be the Supervised Training Program, a unit available on this Dentistry School that enables the students face the reality of FHP, as well the social and economical reality of the families assisted by this program

In vitro evaluation of fluoride products in the development of carious lesions in deciduous teeth

The purpose of this study was to evaluate the effect of the application of fluoride products on the development of enamel caries in deciduous teeth. A total of 108 deciduous teeth were chosen for the study. Acid-resistant varnish was applied on the teeth, leaving only one area of 5 mm x 1 mm of dental enamel exposed. The teeth were allocated randomly to one of the following groups: 1) control - toothpaste without fluoride; 2) 1.23% fluoride gel; 3) Duraflur fluoride varnish; 4) Duraphat fluoride varnish; 5) Fluorniz fluoride varnish; 6) Fluorphat fluoride varnish; 7) varnish with Duofluorid; 8) 12% silver fluoride diamine (Cariestop); 9) children's fluoride toothpaste (500 ppm). The tested products were applied on the teeth according to the manufacturer's recommendations and the teeth were stored in a moist environment for 24 hours. Each group of teeth was then subjected to a pH cycling model for 14 days, after which the teeth were cut through the center for an analysis of the depth of the carious lesion by polarized light microscopy. Comparisons were made between the treatments and the control group. The mean lesion depth values were 318 &#956;m ± 39 (control), 213 &#956;m ± 27 (fluoride gel), 203 &#956;m ± 34 (Duraflur), 133 &#956;m ± 25 (Duraphat), 207 &#956;m ± 27 (Fluor-niz), 212 &#956;m ± 27 (Fluorphat), 210 ± 28 (Duofluorid), 146 ± 31 (Cariestop) and 228 ± 24 (fluoride toothpaste). None of the products used here was able to completely prevent the formation of lesions. The highest cariostatic effect was achieved by fluoride varnish Duraphat and the lowest by the fluoride toothpaste
