ABSTRACT
Proposta: Avaliou-se a liberação de fluoretos de materiais ionoméricos através de colorimetria e potenciometria. Material e métodos: Utilizaram-se três cimentos ionoméricos, sendo dois compômeros, e um ionômero de vidro resinoso. Preparou-se 10 amostras para cada um dos três materiais analisados. A liberação de fluoreto foi medida após 24 horas e no 15° dia. As amostras foram estocadas em 40ml de água deionizada a qual era trocada a cada 24 horas. Desta solução 20 ml serviu para mensurar os níveis de fluoretos através de colorimetria e 20 ml para análise potenciométrica. Resultados: Quanto ao desempenho dos materiais ambas análises apresentaram o mesmo comportamento estatístico com diferença estatística significante (ANOVA = p<0,05) em qualquer um dos intervalos de tempo avaliados. A partir destes resultados, obteve-se elevada correlação estatística (Person r = 0,971). Conclusão: Tanto a análise por colorimetria quanto por eletrodo específico mostraram-se adequadas e estatisticamente correlacionadas
Objective: It was studied fluoride release from glassionomer cement by means of colorimetric and potentiometry. Materials and methods: It was used three ionomeric cements, have been two compomers and one resin based ionomer. The fluoride release was measured after 24 hours and on 15° day . The samples were storage in 40ml deionized water that have been changed each 24 hours. From this solution 20 ml were used to potentiometry and others 20ml were used to colorimetric measurements. Results: The materials behavior in both analysis showed the same statistic difference (ANOVA p<0,05) independent the time spend. From this results high correlation were obtained between analysis methods (Person r = 0,971). Conclusion: Colorimetric and potentiometry analysis showed able to use and statistic correlated

Objetivo: O objetivo desse estudo foi através de revisão bibliográfica elucidar a aplicação do Botox como alternativas terapêutica para o tratamento do sorriso gengival. Revisão: Qualquer exposição gengival ao sorriso natural ou ao discurso, superior a uma faixa contínua de gengiva de 3mm, caracteriza sorriso gengival. Este possui frequentemente causa multifatorial, podendo estar presente excesso de crescimento vertical da maxila, contração labial excessiva, lábio superior curto, excesso gengival e extrusão dos dentes anteriores. Conclusão: O Botox pode ser utilizado como alternativas terapêuticas para o tratamento do sorriso gengival somente quando a etiologia for causada por hipercontração labial
Objective: The aim of this study was by means of literature review shown the clinical application to Botox as treatment alternatives to gummy smile. Review: The exposure of gingival display shape during natural smile over than 3mm calls gummy smile. The ethiology is multifactorial and can be showed excessive vertical maxillary grow up, excessive labial contraction, shorter upper lip, gingival excess and extrusion of the anterior teeth. Conclusion: the botox therapeutics alternative can be used only in muscle hyperactive

Tooth avulsion is a very common event in children and emergency care procedures are crucial for case prognosis. As anyone at the moment of accident can provide first-aid measures, knowledge of school professionals dealing with children is of paramount importance. An informative campaign about dental trauma was performed in urban schools in the city of Adamantina, São Paulo state, Brazil, in an attempt to educate school professionals about emergency procedures in cases of tooth avulsion. A questionnaire arguing on personal information, tooth avulsion knowledge and personal impressions of the campaign was handed out for evaluation of the informative campaign. Eighty school professionals participated in the survey. Most participants were females (93.75 percent) aged 41-60 years old (53.75 percent) with a college degree (77.5 percent). Time at work ranged from 1-5 years (22.5 percent). The efficacy of the campaign was considered positive, as 100 percent of the interviewees replied to the importance of emergency procedures in case of tooth avulsion. In addition, 81.25 percent of the respondents answered that they would store the avulsed tooth in some storage medium, of which milk was the most frequently mentioned (84.61 percent). The participants considered the campaign as satisfactory and a region-wide campaign will be accomplished at other schools.
