Resumo: | Purpose: To evaluate the surface roughness and dimensional stability of types III and IV gypsum models, obtained from irreversible hydrocolloid impressions after disinfection with 5.25% sodium hypochlorite steam. Methods: The impressions to obtain type III and type IV gypsum models were divided into 3 groups: Group 1 (disinfection with 5.25% sodium hypochlorite steam for 10 minutes); Group 2 (simulated disinfection with distilled water steam) and Group 3 (no treatment). To measure the dimensional changes with a digital caliper, 36 models (18 for each type of gypsum) were cast according to a stainless steel master model with four pillars. For the surface roughness measurement, 36 gypsum models were cast from the impressions of the polished stainless steel platform. The data were analyzed using ANOVA and Tukey’s test (α=1%). Results: There was no statistically significant difference in linear dimensions or surface roughness when the different disinfection treatments were compared (Groups 1, 2 and 3), for all types of gypsum. Conclusion: The disinfection treatments with sodium hypochlorite steam and distilled water steam for irreversible hydrocolloid impressions did not significantly affect the dimensional stability and surface roughness of the types III and IV gypsum dental models. |

Metodologia: Os moldes para obtenção dos modelos de gesso tipo III e tipo IV foram designados: Grupo 1 (desinfecção com vapor de hipoclorito de sódio 5,25% por 10 minutos); Grupo 2 (simulação de desinfecção com vapor de água destilada) e Grupo 3 (sem tratamento). Para medição das alterações dimensionais, moldou-se modelo mestre de aço inox com quatro pilares e confeccionou-se 36 modelos (18 para cada tipo de gesso) e as distâncias foram mensuradas com paquímetro digital. Para leitura da rugosidade, confeccionaram-se 36 modelos a partir de moldes de plataforma de aço inox polida e avaliou-se a superfície dos gessos com rugosímetro. Os dados foram submetidos à análise de variância e teste de Tukey (α=1%). Resultados: Na medição das dimensões lineares entre pilares e leitura da rugosidade superficial, não houve diferença estatística significativa, quando comparados os tipos de tratamento (Grupos 1, 2 e 3) em nenhum dos tipos de gesso. Conclusão: Os tratamentos dos moldes de hidrocolóide irreversível com vapor de hipoclorito de sódio e água destilada não afetaram significantemente a estabilidade dimensional e a rugosidade superficial dos modelos de gesso tipo III e tipo IV.EDIPUCRS - Editora Universitária da PUCRS2010-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articlein vitro; experimentallaboratorial; experimental; in vitroapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/6252Revista Odonto Ciência; Vol. 25 No. 3 (2010); 276 - 281Revista Odonto Ciência; v. 25 n. 3 (2010); 276 - 2811980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/6252/5548Moura, Carmem Dolores Vilarinho Soares deMoura, Walter Leal deFrança, Fabiana Mantovani GomesMartins, Gregório Antônio SoaresNogueira, Lorenna Bastos Lima VerdeZanetti, Raquel Vírginiainfo:eu-repo/semantics/openAccess2013-11-11T12:30:19Zoai:ojs.revistaseletronicas.pucrs.br:article/6252Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T12:30:19Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
