No. of bitstreams: 1 AmandaOG.pdf: 325824 bytes, checksum: 9e23aa85acfa497e2743d17a723084a9 (MD5) Previous issue date: 2006-05-19 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The purpose of this study was to evaluate the effectiveness during a twelve-month period, of resin-modified glass ionomer (Vitremer@) used as fissure sealants compared to supervised teeth brushing in the prevention of oclusal caries in permarient molars of pubIlc school children from 5 to 7 years of age. A total of 91 children participated in the study, being randomly divided up into three groups of investigation: group with sealant (n=31), group of supervised brushing (m=30), and control gorup (n=30). After 12 months, a total of 28.5% of tosses in the sample of 26 children was registered, and although there wasn t a significant diference between these losses and the groups studles (p = 0.6355), there was a considerable reduction in the sample. The results showed that none of the independentIy studied variables (present caries experience, biofilm, bleeding, sealant retention, position of the tooth in the arch, and sex) interfered in the final results, and that there was no significant difference between applying the sealant in question, perfornling supervised dental brushing, or not intervening at alI (p=0.542). These results could have been a consequence of the limitations found alI through the study, especially relating to the losses occurred because of school evasion, transfer, or because of the accident in the Marise Paiva Municipal School, Keeping students away for approximately one semester, so tht a new reseach had to be developed sos as to better clarify the effects among the treatments done there / O presente estudo teve por finalidade avaliar a efic?cia de selante ionom?rico modificado por resina (Vitremer@), comparado com a escova??o dent?ria supervisionada na preven??o de c?rie ociusal em molares permanentes de escolares da rede p?blica, na faixa et?ria de 5 a 7 anos, ao fmal de 12 meses. Um total de 91 crian?as participou do estudo, sendo divididas aleatoriamente nos tr?s grupos de investiga??o: grupo dos selantes (n=31), grupo da escova??o supervisionada (n=3O) e grupo controle (n=30). Ao final de 12 meses, registrou-se um total de perdas equivalente a 28,5% da amostra (26 crian?as) e, embora n?o tenha havido diferen?a significativa entre essas perdas e os grupos estudados (p=O,6355), houve uma redu??o consider?vel da amostra. Os resultados mostraram que nenhuma das vari?veis independentes estudadas (experi?ncia atual de c?rie, biofilme, sangramento, reten??o do selante, posi??o do dente no arco e sexo) interferiu no desfecho final, e que n?o houve diferen?a significativa entre aplicar o selante em quest?o, realizar a esc ova??o dent?ria supervisionada e n?o efetuar nenhuma interven??o (p=O,542). Estes resultados podem ter sido conseq??ncia das limita??es encontradas ao longo do estudo, sobretudo no que se refere ?s perdas ocorridas em virtude de evas?o escolar, transfer?ncia ou em decorr?ncia do acidente na Escola Municipal Marise Paiva, afastando os alunos de suas ... atividades por aproximadamente um semestre, de modo que novas pesquisas necessitam ser desenvolvidas com o prop?sito de elucidar melhor os efeitos entre os tratamentos aqui realizados

No. of bitstreams: 1 AdrianaGA.pdf: 511387 bytes, checksum: efbc267a66385231b4ff2e6eba3f58a8 (MD5) Previous issue date: 2005-03-03 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Bioethics studies human behavior in the fields ofbiological sciences and health care. Tt strives for humanization in health services along with promoting the rights of patients. In view of the lack of dental research dealing with this topic, the present study was undertaken to identify, from the viewpoint of dental surgeons, ethical problems experienced in dental practice,understand how they occur and how professionals deal with them. It is a descriptive exploratory investigation within a qualitative approach. Empirical material was collected through semi-structured interviews performed with 15 dental surgeons who work both in private and public practice in the state of Rio Grande do Norte, Brazil. The content of the interviews was systemized and organized, resulting in the identification of topics, from which were grouped the ethical problems reported by the participants. The resu1ts indicate that many of the ethical problems coincide with infringements of the norms and mIes of the Dental Code of Ethics, confirming a dental ethic acquired during professional formation and therefore, inadequate for solving the problems that emerge in professional practice. Other questions stand out such as low salaries, competition and poor working conditions. Associated to these problems are lack of commitment and professional responsibility with the patients. Concem with maintaining user autonomy, guaranteeing access to specialized services, and the need for performing only procedures for which they are technically qualified arise in the responses, leading to difficulties in consolidating the principIes proclaimed by bioethics: autonomy, justice, nonmaleficence and beneficence. We concluded that the ethical problems identified in professional practice need to be understood beyond the dental dimension, towards a human approach. It is therefore necessary to incorporate health care management technologies into health practices, including dentistry, which implies recognizing the difTerent dimensions that surround individuaIs, that is, social, economic, political and cultural / A bio?tica estuda a conduta humana no campo das ci?ncias biol?gicas e da aten??o ? sa?de. Tem como caracter?sticas principais a busca pela humaniza??o dos servi?os de sa?de e a promo??o dos direitos dos pacientes. Partindo do pressuposto que na Odontologia s?o escassos os estudos que tratam dessa tem?tica, a presente pesquisa foi desenvolvida com o objetivo de identificar, a partir da vis?o dos cirurgi?es-dentistas, os problemas ?ticos vivenciados na pr?tica odontol?gica, buscando compreender como se produzem e como os profissionais lidam com eles. Trata-se de uma investiga??o de car?ter explorat?rio descritivo, dentro de uma abordagem qualitativa. O material emp?rico foi coletado por meio de entrevistas semi-estruturadas, realizadas com 15 cirurgi?es-dentistas que atuam tanto no ?mbito privado, quanto no p?blico da presta??o de servi?os odontol?gicos no Estado do Rio Grande do Norte. O conte?do das entrevistas foi sistematizado e organizado, resultando na identifica??o de temas, a partir dos quais agrupamos os problemas ?ticos relatados pelos participantes. Os resultados apontam que muitos dos problemas ?ticos coincidem com infra??es ?s normas e regras do C?digo de ?tica Odontol?gica, confirmando uma no??o de ?tica deontol?gica adquirida na forma??o profissional e, portanto, insuficiente para solucionar os problemas que emergem na pr?tica profissional. As quest?es de mercado tamb?m aparecem com lugar de destaque, referentes aos baixos sal?rios, ? concorr?ncia e ?s condi??es inadequadas de trabalho. Associado aos problemas ?ticos que emergem nas rela??es de mercado, s?o referidos a falta de compromisso e de responsabilidade profissional com os usu?rios. As preocupa??es em preservar a autonomia dos usu?rios, em garantir o acesso aos servi?os de refer?ncia especializada, a necessidade de realizar somente procedimentos para os quais estivessem capacitados tecnicamente surgiram nas falas, traduzindo-se em dificuldades na efetiva??o dos princ?pios preconizados pela bio?tica principialista: autonomia, justi?a, n?omalefic?ncia e benefic?ncia. Conclu?mos que os problemas ?ticos identificados na pr?tica profissional precisam ser compreendidos para al?m da dimens?o deontol?gica em dire??o aos aspectos da produ??o do trabalho. Torna-se preciso, ent?o, incorporar nas pr?ticas de sa?de, incluindo a odontologia, as tecnologias da gest?o do cuidado, o que implica no reconhecimento de diferentes dimens?es que envolvem os sujeitos, ou seja, sociais, econ?micas, pol?ticas e culturais

Efic?cia do cimento de ion?mero de vidro como selante oclusal sobre a paralisa??o de les?es cariosas em dentina

Silveira, Ana Daniela Silva da 30 March 2007 (has links)
Made available in DSpace on 2014-12-17T15:31:01Z (GMT). No. of bitstreams: 1 AnaDanielaSS.pdf: 1240978 bytes, checksum: 056e910f21f25b07dc5d0271950d9b13 (MD5) Previous issue date: 2007-03-30 / Dental caries consists in a multifactorial and dynamic process. The knowledge of the ionic interactions among dental tissues and dental biofilm make possible its understanding as a process that can be stopped. Recently, the use of sealants have lost its function as preventive agent and passed to be argued as a possible therapeutical agent. This happens by hindering the substratum flow to the lesion inner and, therefore, controls the advance of the process. This study aimed to evaluate glass ionomer cement as a not invasive technique of treatment in occlusal caries without clinical cavitation, but with dentinal involvement. The research was accomplished using a controlled clinical trial with two groups (experimental and control) in 38 subjects (8-18 years) with 51 molars. The teeth of the experimental group were sealed with glass ionomer cement (Vidrion-R, S.S.White, Juiz de Fora, Brazil) and the molars control did not suffer intervention. The experimental group was followed by a year and the control by 8 months due the progression of the carious injury. Both groups were reevaluated to each 4 months with the use of clinical, radiographic and laser fluorescence (DIAGNOdent?) examination. The analysis of the clinical evaluation did not observe a significant difference between experimental and control groups. However, analysis with radiographic and laser fluorescence (DIAGNOdent?) examination observed a significant difference (p> 0,05) between groups, demonstrating a wors condition to the group without intervention. The results suggest that glass ionomer cement as sealant can be efficient to paralyze dentinal caries without clinical cavitation / A c?rie consiste de um processo multifatorial e din?mico. O conhecimento das intera??es i?nicas entre os tecidos dent?rios e o biofilme possibilitaram a sua compreens?o como um processo pass?vel de paralisa??o. Recentemente, o uso de selantes deixou sua fun??o estrita de agente preventivo e passou a ser discutido como um poss?vel agente terap?utico, pois, impedindo o fluxo de substrato para o interior da les?o, poderia controlar o avan?o do processo carioso. Este estudo objetivou avaliar uma t?cnica n?o invasiva de tratamento em c?rie oclusal sem cavita??o cl?nica, mas com comprometimento dentin?rio detectado atrav?s do exame radiogr?fico. A pesquisa foi realizada por meio de um ensaio cl?nico controlado com dois grupos (um experimental e um controle) em 38 indiv?duos (8-18 anos) totalizando 51 molares permanentes. O grupo experimental foi selado com cimento de ion?mero de vidro restaurador (Vidrion-R, S.S.White, Juiz de Fora, Brasil) e o grupo controle n?o sofreu interven??o. Os grupos experimental e controle foram acompanhados por at? um ano. Ambos os grupos foram reavaliados a cada 4 meses por meio de exame cl?nico, radiogr?fico e fluoresc?ncia a laser (DIAGNOdent?). A an?lise do exame cl?nico n?o mostrou diferen?a entre os grupos de investiga??o. No entanto, o exame radiogr?fico e a fluoresc?ncia a laser (DIAGNOdent?) demonstraram uma diferen?a significativa (p>0,05) entre os grupos experimental e controle, demonstrando um agravo da condi??o estudada para o grupo onde n?o houve interven??o. Os resultados encontrados sugerem que o tratamento n?o invasivo, atrav?s do selamento oclusal com cimento de ion?mero de vidro, pode ser eficaz no caso de c?ries em dentina sem cavita??o cl?nica
