Resumo

Resumo: Introdução: O selamento dentinário imediato consiste na aplicação imediata de um sistema adesivo sobre exposições dentinárias após o preparo dental e previamente aos procedimentos de moldagem.

Objetivo: O objetivo do estudo foi avaliar a influência do selamento dentinário imediato (SDI) na resistência adesiva do sistema adesivo universal (Single Bond Universal, 3M ESPE) em dentina, na forma de aplicação autocondicionante.

Material e método: 30 incisivos bovinos foram divididos em 3 grupos (n = 10): grupo S (Sem Selamento Dentinário Imediato), grupo SDI (Selamento Dentinário Imediato) e grupo SDIF (Selamento Dentinário Imediato + Resina Flow). A superfície vestibular foi desgastada com pontas diamantadas até a exposição superficial de dentina. A simulação da lama dentinária foi realizada com lixa d’água por 30s e a dentina tratada de acordo com o respectivo grupo. Para simulação da restauração provisória, foram cimentados blocos de resina bisacrílica com cimento de óxido de zinco. Após 7 dias, foi realizada a cimentação definitiva de blocos de resina com cimento resinoso dual (RelyX ARC, 3M ESPE). Os espécimes foram seccionados para obtenção de filetes de 1mm2 e submetidos ao teste de microtração, em uma máquina universal de ensaios (Instron). Os resultados foram tabulados e submetidos a Análise de Variância (ANOVA) e teste de Tukey a 5% de significância.

Resultado: Observaram-se maiores valores de resistência de união para o grupo SDIF (23,53 MPa), diferindo estatisticamente do Grupo S (17,65 MPa) (p=0,008). O grupo SDI apresentou valor médio de resistência de união (19,25 MPa), não diferindo estatisticamente dos grupos S (p=0,68) e SDIF (p=0,07).

Conclusão: Recomenda-se a técnica de selamento dentinário imediato seguido da uma camada de resina flow, em exposições dentinárias ocasionadas pelo preparo dental para restaurações indiretas.

Abstract

Abstract: Introduction: Imediate dentin sealing (IDS) is a procedure where a dentin adhesive is applied on the exposed dentin surfaces after its preparation to indirect restorations and before impression procedures.

Objective: The objective of the study was to evaluate the effectiveness of the immediate dentin sealing technique (SDI) in adhesive resistance, using the Universal adhesive system (Single Bond Universal, 3M ESPE).

Material and method: 30 bovine incisors were selected and divided into 3 groups (n = 10): Groups S (Without Immediate Dentin Seal), SDI (Immediate Dentin Seal with Adhesive) and SDIF (Immediate Dentin Seal with Adhesive + Flow Resin). The vestibular surface was worn with diamond-tipped conical tips until superficial dentin exposure. The smear layer simulation was carried out with # 600 granulation sandpaper for 30s and the dentin was treated according to the respective group. To simulate the temporary restoration, blocks of bisacrylic resin were cemented with zinc oxide cement. After 7 days, the final cementation of resin blocks with dual resin cement (RelyX ARC, 3M ESPE) was carried out. The specimens were sectioned to obtain 1mm2 fillets and subjected to the microtensile test.

Result: The ANOVA test showed a statistical difference between the groups evaluated. Higher values of bond strength were observed for the SDIF group (23.53 MPa), differing statistically from Group S (17,65 MPa) (p = 0.008). The SDI group showed an average bond strength (19.25 MPa), which did not differ statistically from groups S (p = 0.68) and SDIF (p = 0.07).

Conclusion: Based on the results, it is recommended the immediate dental sealing technique with adhesive + flow resin in dental exposures caused in the dental preparation for indirect restorations.
