The purpose study was to test nine commercial brands of glass ionomer (Chelor Fill, Chelon Silver, Fuji II LC, Variglass Azul Variglass DY, Vitrebond, Vitremer Cimentaçãc e Vitremer Restauração) in order to identify one that is most radiopaque. This informatior would help in a future radiographic diagnosis o: analysis. In carrying out this experiment, nine glas ionomer samples were made from the nine brands mentioned above, and the oclusal anc apical regions of nine premolars teeth wert restored. Later, the samples as well as the restoœc premolars wcre submited to radiographi¿ exposure. The subjects went through densitometric evaluation, and the premola5 were visually evaluated by ten observers. In both densitometric and visua. evaluation, the results showed Chelon Silver as the most radiopaque of the glass ionome: followcd by Variglass DY. The least radiopaqut was Chelon Fili.
Uma das mais recentes preocupações no controle de infecções em Odontologia é a contaminação da água usada nos procedimentos odontológicos. O estudo proposto avaliou a qualidade da água que alimenta as canetas de alta rotação de 4 Ambulatórios da Faculdade de Odontologia da UFRGS, através de uma análise microbiológica quantitativa. Em um total de 27 amostras de água analisou-se: o número de unidades formadoras de colônias por mililitro (UFC/ml), através da contagem de bactérias heterotróficas pelo método de "Pour Plate" e a presença ou ausência de coliformes totais e de coliformes fecais usando o método dos "Túbulos Múltiplos". Os resultados revelam que 24 das 27 (88,89%) amostras analisadas, coletadas nos 4 Ambulatórios, estavam fora dos padrões de potabilidade, segundo a Portaria n° 36 de 19 de janeiro de 1990, apresentando contagens de UFC/ml com uma variação de 1,2 a mais de 130 vezes além do máximo permitido. Apenas uma das amostras apresentou coliformes totais e nenhuma das amostras apresentou coliformes fecais.
No período de março a maio de 1995, foi realizado na Faculdade de Odontologia da UFRGS, pelos alunos do 6° semestre, um levantamento sobre a opinião e o grau de satisfação dos pacientes quanto ao atendimento recebido nesta instituição. Para tanto, foram realizadas entrevistas com 61 pacientes que estavam retornando para atendimento no periodo citado. A partir disso, observou-se que os pacientes estão satisfeitos com o atendimento e ambiente físico da faculdade, acreditam na competéncia do aluno e indicariam o atendimento recebido para outras pessoas.
Objetivo: Este trabalho tem por objetivo verificar a freqüência das complicações relacionadas à retenção do terceiro molar inferior. Materiais e métodos: Os dados foram obtidos nos prontuários dos pacientes atendidos no Centro de Tratamento Buco-Maxilo-Facial do Departamento de Cirurgia e Ortopedia da Faculdade de Odontologia da Universidade Federal do Rio Grande do Sul no período de janeiro de 1996 a julho de 1999. O instrumento de coleta de dados é composto por itens referentes ao sexo, idade, raça, presença ou não de terceiro molar inferior retido, classificação das retenções e complicações associadas à retenção. Foram selecionados os casos de retenção dos terceiros molares inferiores (38 e 48), levantadas as complicações das retenções e realizada a relação destas com as variáveis sexo, idade, raça e classificação das retenções. Resultados: Detectou-se 366 dentes dentes retidos, sendo 110 dentes com e 256 sem complicação. A pericoronarite foi a complicação mais freqüente para os dentes 38 (60%) e 48 (63%), seguida por cisto, rizólise e cárie. Conclusões: A pericoronarite foi a complicação predominante (61,8%) e o sexo feminino, nesses casos, foi o mais freqüente (58,8%). Considera-se a extração profilática como indicada para terceiros molares inferiores retidos.
1035 students in third grade of secondary school, in São Luís, the capital of Maranhão, Brazil, were examined. The mean age of them was about 18 years old. Utilizing a plan mirror and explorers number 5, each student in the study received a clinical dentel examination for diagnosing caries prevalence, through the DMF index and its components, by half maxilla and half jaw. In 99,50 per cent of the population studied, an average of caries incidence was 12,37 DMF by person and dental caries reached 44,31 per cent of erupted teeth. The highest caries incidence was on the superior arcade, in special in the left half maxilla. On the average, each student had 4,68 lost teeth; 4,72 with caries; and 2,87 restered. 15,10 per cent did not have removed teeth and 50,10 per cent needed at least, dental extraction. 45,50 per cent did not have restoretion.
This study reports an evaluation of a program performed by seniors students at the Faculdade de Odontologia de São José dos Campos (Brazil) during the development of clinical activities in Extra-Mural Programs. The analysis of efficiency (productivity, program-costs and time) and work environment conditions was carried out by comparison between two different types of dental units: a standart unit and a mobile dental unit. The data indicated that better efficiency and work environmental conditions were found in the standart unit.
The aim of the present paper is to prove the difficult of diagnosis and the variations in clinical procedure from Bite Wing x-rays as well as to analyze the relation teaching - leaving based on such x-rays. To reach the objective of the research we counted on the participation os students from the 6th and 8th semesters of F.O. UFRGS who made the diagnosis and conducted the clinical procedures based on the 4 Bite Wing x-rays. These had been previosly analysed by the professors of the course on Radiology, the results of which were taken as a pattern. The research sought to identify the existance of homogeneity or the lack of it, in the formulation of diagnosis and of clinical procedures, using as criteria the variables of sex and level of education.
The water-powder relationship is essential to achieve a proper performance of gypsum for prosthetic purposes. The ideal measure can be obtained with a balance, but this is clinically unavailable, once it is timeconsuming. A powder-compacting technique using a volume measurement is suggested in order to substitute the balance. The technique consists of using a gypsum meter within the gypsum bag. While the operator holds the gypsum meter with one hand, the palm of the other hand is pressed over the surface of the meter, supported by the ventral aspect of the fingers of the hand that is pressing. This procedure is based upon three compactation movements for each operator, then counting the average of compacting sample. Each of the ten operators repeated six times the procedure, and the final average was defined. The resulting samples for each procedure, of each operator, were weighted, and the statistical analysis showed significant differences (p = 0,006) among the operators.
