Resumo: | Chemical substances used in endodontic treatment can affect the quality of adhesion in the final restoration. The moment of dentin hybridization (HD) can act to minimize the effects of these substances on dentin and influence the quality of adhesion. This study evaluated the timing of HD and different chemical substances in dentin bond strength in human teeth. Twenty human molars were distributed in four experimental groups: G1. RD - direct restoration in composite resin, the control group being without exposure to chemical substances or temporary restoration; G2. HDT - late dentin hybridization with HD at the time of final restoration, after exposure to chemicals and temporary restoration; G3. HDI - immediate dentin hybridization with HD after simulation of endodontic treatment and prior to provisional restoration; G4. HDP - previous dentin hybridization with HD prior to exposure to chemical substances and temporary restoration. The coronary dentin was exposed, submerged with 2.5% sodium hypochlorite, 17% EDTA and endodontic cement, molded with addition silicone, temporarily restored, and stored for 2 weeks in artificial saliva. Then it was restored with composite resin and the microtensile test was performed after 24 hours. The toothpicks were cut to a size of 1mm² and subjected to microtraction at 0.05mm / min (MPa) in the universal testing machine. After assessing normality and homogeneity, the microtensile bond strength values were analyzed using ANOVA, a 5% significance test, followed by a post hoc test (Tukey). The highest bond strength value was found in the control group (42.39 MPa ± 5.69), followed by the HDP group (41.51 MPa ± 3.68), the HDI group (21.16 MPa ± 9.66) and the lowest value in the HDT group (9.86 MPa ± 1.30). The control group (RD) showed no statistically significant difference in relation to the previous dentin hybridization (HDP) approach. The HDI and HDT groups showed a decrease in the tensile strength value when compared to the control group of 76.7% and 50.1%, respectively. It can be concluded that dentin hybridization prior to exposure to chemical substances used in endodontic treatment positively influenced the microtensile bond strength of the studied samples. |

O momento da hibridização dentinária (HD) pode atuar minimizando os efeitos dessas substâncias na dentina e influenciar na qualidade de adesão. Este estudo avaliou o momento da realização da HD e de diferentes substâncias químicas na resistência de união à dentina em dentes humanos. Vinte molares humanos foram distribuídos em quatro grupos experimentais: G1. RD - restauração direta em resina composta, sendo o grupo controle sem exposição às substâncias químicas ou restauração provisória; G2. HDT - hibridização dentinária tardia com HD no momento da restauração final, após exposição às substâncias químicas e restauração provisória; G3. HDI - hibridização dentinária imediata com HD após a simulação do tratamento endodôntico e previamente à restauração provisória; G4. HDP - hibridização dentinária prévia com HD previamente à exposição às substâncias químicas e restauração provisória. A dentina coronária foi exposta, submersa com hipoclorito de sódio 2,5%, EDTA 17% e cimento endodôntico, moldada com silicone de adição, restaurada provisoriamente, e estocada por 2 semanas em saliva artificial. Em seguida foi restaurada com resina composta e o teste de microtração foi realizado após 24 horas. Os palitos foram cortados no tamanho de 1mm² e submetidos ao microtracionamento a 0,05mm/min (MPa) na máquina de ensaio universal. Após avaliação de normalidade e homogeneidade, os valores de resistência de união à microtração foram analisados por meio de ANOVA, teste de significância de 5%, seguidos por teste post hoc (Tukey). O maior valor de resistência de união foi encontrado no grupo controle (42,39 MPa ±5,69), logo em seguida o grupo HDP (41,51 MPa ±3,68), o grupo HDI (21,16 MPa ±9,66) e o menor valor no grupo HDT (9,86 MPa ±1,30). O grupo controle (RD) não apresentou diferença estatisticamente significante em relação a abordagem de hibridização dentinária prévia (HDP). Os grupos HDI e HDT apresentaram uma diminuição do valor de resistência a tração quando comparados ao grupo controle de 76,7% e 50,1%, respectivamente. Pode-se concluir que a hibridização dentinária previamente à exposição a substâncias químicas utilizadas no tratamento endodôntico influenciou positivamente a resistência de união à microtração das amostras estudadas.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2020-09-14T13:06:04Z No. of bitstreams: 2 license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5) Dissertação - Thabata Frederico Izelli - 2020.pdf: 2723782 bytes, checksum: 8ccb2ab879eeb972359237f2fbd2e7b0 (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2020-09-15T11:22:34Z (GMT) No. of bitstreams: 2 license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5) Dissertação - Thabata Frederico Izelli - 2020.pdf: 2723782 bytes, checksum: 8ccb2ab879eeb972359237f2fbd2e7b0 (MD5)Made available in DSpace on 2020-09-15T11:22:34Z (GMT).

Chemical substances used in endodontic treatment can affect the quality of adhesion in the final restoration. The moment of dentin hybridization (HD) can act to minimize the effects of these substances on dentin and influence the quality of adhesion. This study evaluated the timing of HD and different chemical substances in dentin bond strength in human teeth. Twenty human molars were distributed in four experimental groups: G1. RD - direct restoration in composite resin, the control group being without exposure to chemical substances or temporary restoration; G2. HDT - late dentin hybridization with HD at the time of final restoration, after exposure to chemicals and temporary restoration; G3. HDI - immediate dentin hybridization with HD after simulation of endodontic treatment and prior to provisional restoration; G4. HDP - previous dentin hybridization with HD prior to exposure to chemical substances and temporary restoration. The coronary dentin was exposed, submerged with 2.5% sodium hypochlorite, 17% EDTA and endodontic cement, molded with addition silicone, temporarily restored, and stored for 2 weeks in artificial saliva. Then it was restored with composite resin and the microtensile test was performed after 24 hours. The toothpicks were cut to a size of 1mm² and subjected to microtraction at 0.05mm / min (MPa) in the universal testing machine. After assessing normality and homogeneity, the microtensile bond strength values were analyzed using ANOVA, a 5% significance test, followed by a post hoc test (Tukey). The highest bond strength value was found in the control group (42.39 MPa ± 5.69), followed by the HDP group (41.51 MPa ± 3.68), the HDI group (21.16 MPa ± 9.66) and the lowest value in the HDT group (9.86 MPa ± 1.30). The control group (RD) showed no statistically significant difference in relation to the previous dentin hybridization (HDP) approach. The HDI and HDT groups showed a decrease in the tensile strength value when compared to the control group of 76.7% and 50.1%, respectively. It can be concluded that dentin hybridization prior to exposure to chemical substances used in endodontic treatment positively influenced the microtensile bond strength of the studied samples. |
