Resumo: | The aim of this study was to evaluate the pulpal response of dogs primary teeth to an adhesive system or to a calcium hidroxide cement after mechanic exposure of the pulp. Three mongrel dogs were used and ten class V cavities were prepared on their teeth. A mechanic pulp exposure was produced with a sterile exploratory probe in the central portion of each cavity and bleeding was controlled with dry sterile cotton pellets. Enamel, dentin and the site of the pulp exposure of five teeth were etched with 35% phosphoric acid followed by the application of an adhesive system (Scotchbond Multi-Purpose - 3M). In the other five teeth, calcium hydroxide cement (Hydro C - Dentsply) was applied on the site of the pulp exposition before application of the adhesive system (Scotchbond Multi-Purpose - 3M). All teeth were restored with a resin composite (Z-100 - 3M). After 7, 30 or 45 days the dogs were anesthetized and perfused with saline followed by a solution of neutral buffered formalin. Maxilla and mandible were sectioned into three parts and placed in a solution for demineralization. Following bone demineralization, all teeth were cut, trimmed, embedded in paraffin and longitudinally cut. Then, the teeth were stained with hematoxilin and eosin and observed under a light microscope. The results obtained with the treatments proposed in this study showed the presence and persistence of an inflammatory response of different intensities at the three experimental periods. There was no variation in the inflammatory response regarding the different treatments performed. |

Foram utilizados três cães sem raça definida, e nestes foram realizados dez preparos cavitários classe V. Uma exposição pulpar mecânica foi produzida com uma sonda exploradora esterilizada, na porção central de cada cavidade. A hemorragia foi controlada com bolinhas de algodão esterilizadas. O esmalte, dentina e local da exposição pulpar de cinco dentes foram condicionados com ácido fosfórico a 35%, seguido da aplicação de um sistema adesivo (Scotchbond Multi-Uso - 3M). Nos outros cinco dentes, um cimento de hidróxido de cálcio (Hydro C - Dentsply) foi aplicada no local da exposição pulpar antes da aplicação do mesmo sistema adesivo. Todos os dentes foram restaurados com uma resina composta (Z-100 - 3M). Após 7, 30 ou 45 dias os cães foram anestesiados e perfundidos com solução salina seguida de uma solução de formalina neutra tamponada. A maxila e a mandíbula foram seccionadas em três partes e estocadas em uma solução para desmineralização. Após a desmineralização óssea, todos os dentes foram cortados, incluídos em parafina e seccionados longitudinalmente. A seguir todos os dentes foram corados com hematoxilina e eosina e observados em microscópio de luz. Os resultados demonstraram a presença e persistência de uma resposta inflamatória de diferentes intensidades nos três períodos experimentais. Não houve variação na resposta inflamatória pelos diferentes tratamentos propostos.Universidade Federal de Juiz de Fora, School of DentistryUniversidade de São Paulo, School of DentistryUniversidade Estadual Paulista, School of DentistryUniversidade Estadual Paulista, School of DentistrySociedade Brasileira de Pesquisa Odontológica e Faculdade de Odontologia da Universidade de São PauloUniversidade Federal de Juiz de ForaUniversidade de São Paulo (USP)Universidade Estadual Paulista (Unesp)Ribeiro, Rosângela AlmeidaMyaki, Silvio Issáo [UNESP]Gioso, Marco AntônioAraújo, Ney Soares De2021-07-14T10:48:32Z2021-07-14T10:48:32Z2000-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article47-52application/pdfhttp://dx.doi.org/10.1590/S1517-74912000000100009Pesquisa Odontológica Brasileira.
