Resumo: OBJECTIVE: To investigate the pulpal response to direct pulp capping in healthy human teeth with Portland cement (PC) as against mineral trioxide aggregate (MTA) as control.METHODS: Forty healthy human third molars indicated for extraction were randomly divided into two groups: PC and MTA. The teeth had iatrogenic pulp exposed and direct pulp capping with PC or MTA. After 1, 7, 14 and 21 days, the teeth were extracted and prepared for histological examination and bacterial detection. The Mann-Whitney test was applied for statistical analysis (p < 0.05).RESULTS: The MTA presented higher capacity to form of dentin bridges at 14- and 21-day intervals (p < 0.05). However, no significant statistical difference was found between the groups at all evaluated intervals (p > 0.05) for the response variables of inflammatory cells, soft tissue organization and bacterial staining.CONCLUSION: The PC has a biocompatibility equivalent to the MTA but with a lower capacity to form of dentin bridges. Therefore, MTA should be the material of choice for direct pulp capping.

Os dentes tiveram a polpa exposta iatrogenicamente e em seguida foi realizado o capeamento pulpar direto com PC ou MTA. Após 1, 7, 14 e 21 dias, os dentes foram extraídos e preparados para exame histológico e detecção bacteriana. O teste de Mann-Whitney foi aplicado para análise estatística (p < 0,05).RESULTADOS: O MTA apresentou maior capacidade de formação de pontes dentinárias nos intervalos de 14 e 21 dias (p < 0,05). No entanto, não foi encontrada diferença estatística significativa entre os grupos em todos os intervalos avaliados (p > 0,05) para as variáveis de resposta de células inflamatórias, organização de tecidos moles e coloração bacteriana.CONCLUSÃO: O PC tem uma biocompatibilidade equivalente ao MTA, mas com menor capacidade de formar pontes dentinárias. Portanto, o MTA deve ser o material de escolha para o capeamento direto da polpa.Palavras-chave: biocompatibilidade; polpa humana; agregado de trióxido mineral; cimento portland; capeamento pulpar.EDIPUCRS - Editora Universitária da PUCRS2018-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/2925910.15448/1980-6523.2018.1.29259Revista Odonto Ciência; Vol. 33 No. 1 (2018); 11-15Revista Odonto Ciência; v. 33 n. 1 (2018); 11-151980-65230102-946010.15448/1980-6523.2018.1reponame: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/29259/17879Copyright (c) 2019 Revista Odonto Ciênciainfo:eu-repo/semantics/openAccessBarbosa, Antônio Vinícius HolandaSantos Junior, Valdeci Elias dosMartins, Márcia MarquesFerreira, Leila SoaresSobral, Ana Paula Veras2019-04-24T17:19:21Zoai:ojs.revistaseletronicas.pucrs.br:article/29259Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2019-04-24T17:19:21Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
