Resumo: Purpose: To simulate soft and hard tissues to assess radiopacity of three root canal sealers (Endofill, AH Plus and Sealer 26). Methods: Five circular specimens (10x1 mm) were made and three experimental conditions were created. Situation #1: an aluminum step wedge allowed specimen being submitted to three digital radiographs. Situation #2: a retromolar mandibular segment containing the specimen was positioned between the phosphor plate and X-ray machine. Situation #3: a soft tissue simulating material (utility wax – 30 mm) was associated with the mandibular segment. Mean gray values were measured using ImageTool 3.0 software. Two-way ANOVA and Tukey’s test (alpha=0.05) was performed. Results: Radiopacity increased when bone tissue was used (P < 0.05), except for AH Plus. Situation #3 provided greater radiopacity (P < 0.05). Radiopacity between most and least sealers decreased 44% when Situation #1 and #3 were compared. Conclusion: Simulated soft and hard tissues influenced the radiopacity of root canal sealers.

Metodologia: Cinco espécimes circulares (10x1 mm) foram confeccionados e três situações experimentais foram criadas. Situação #1: espécime e uma escala de alumínio foram submetidos a 3 tomadas radiográficas digitais. Situação #2: um segmento retromolar de uma mandibula humana contendo o espécime foi posicionada entre o aparelho de raio X e o sensor digital. Situação #3: um simulador de tecido mole (cera utilidade – 30 mm) foi associado ao segmento mandibular. A média dos valores de cinza foi medida através do programa ImageTool 3.0. Análise de variância de dois critérios e Teste de Tukey (alfa=0.05) foram realizados para análise estatística. Resultados: A radiopacidade aumentou quando tecido ósseo foi usado (P < 0.05), exceto para o Ah Plus. A Situação #3 proporcionou os maiores valores de radiopacidade (P < 0.05). Os valores de radiopacidade entre o cimento mais e o menos radiopaco diminuiu 44% quando as situações #1 e #3 foram comparadas. Conclusão: A simulação de tecidos moles e duros influencia a radiopacidade de cimentos endodônticos.EDIPUCRS - Editora Universitária da PUCRS2011-10-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/9375Revista Odonto Ciência; Vol. 26 No. 4 (2011); 326 - 330Revista Odonto Ciência; v. 26 n. 4 (2011); 326 - 3301980-65230102-9460reponame: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/9375/7497Rosa, Ricardo AbreuBier, Carlos Alexandre SouzaPereira, Charles CunhaSó, Marcus Vinícus ReisWolle, Carlos Frederico Brilhanteinfo:eu-repo/semantics/openAccess2013-11-11T11:44:27Zoai:ojs.revistaseletronicas.pucrs.br:article/9375Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T11:44:27Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
