Resumen
Objetivo:
Comparar la microfiltración de la técnica adhesiva Single bond Universal y sellante
Concise con el sistema adhesivo gold standard (Optibond Fl).
Materiales y métodos:
Se realizó un estudio in vitro de 36 dientes, molares o premolares sanos con
indicación de exodoncia, recolectados en la Facultad de Odontología UNAB Santiago.
En cada pieza dentaria se realizaron 2 cavidades clase I con las mismas
características. En una cavidad se realizó el protocolo adhesivo con Single bond
Universal adicionando una capa superficial de sellante Concise y en la otra cavidad
se aplicó protocolo adhesivo gold standard (Optibond Fl). Ambas cavidades se
restauraron con resina Bulk Fill en un incremento de 2 mm y se procedió a sellar los
ápices con composite Revolution formula 2 Flow–Kerr. Se realizó el protocolo de
termociclado, con 500 ciclos térmicos entre 5° y 55°C Se cortaron los dientes con disco
diamantado a baja velocidad en sentido transversal de la preparación dividiéndolo en
dos, para visualizar la interfaz restauración-diente. Se sumergieron las 36 piezas en
azul de metileno por 48 horas. Finalmente, cada preparación fue pulida con discos
soflex para la visualización de la microfiltración y eliminar la tinción superficial. Se
evaluó la penetración del colorante azul de metileno en la interfaz simulando la
microfiltración marginal. Se analizaron los resultados a través de una fotografía macro
tomada con cámara profesional evaluando la ausencia o presencia de microfiltración.
Resultados:
Analizando los resultados obtenidos, ambas técnicas adhesivas obtuvieron un 75%
de muestras con microfiltración respectivamente. Obteniendo un valor P=>0.05, lo que
significa que no hay diferencias estadísticamente significativas en cuanto a los datos
recolectados de microfiltración de ambas técnicas.
Conclusión:
Los resultados no mostraron diferencias estadísticamente significativas respecto a
la microfiltración marginal, concluyendo que hay un desempeño similar con relación a
la fuerza adhesiva de ambas técnicas, lo que queda demostrado en la falla adhesiva
en el piso de las cavidades de ambos grupos.
Objective: To compare the microleakage of the Single bond Universal adhesive technique and Concise sealant with the gold standard adhesive system (Optibond Fl). Materials and methods: An in vitro study was carried out on 36 healthy teeth, molars or premolars with indication for exodontia, collected at the Faculty of Dentistry UNAB Santiago. Two class I cavities with the same characteristics were made in each tooth. In one cavity the adhesive protocol was performed with Single bond Universal adding a superficial layer of Concise sealant and in the other cavity the gold standard adhesive protocol (Optibond Fl) was applied. Both cavities were restored with Bulk Fill resin in a 2 mm increment and the apices were sealed with Revolution formula 2 Flow-Kerr composite. The thermocycling protocol was carried out, with 500 thermal cycles between 5° and 55°C. The teeth were cut with a diamond disk at low speed in the transversal direction of the preparation, dividing it in two, to visualize the restoration-tooth interface. The 36 pieces were immersed in methylene blue for 48 hours. Finally, each preparation was polished with soflex discs for visualization of microleakage and removal of surface staining. Penetration of the methylene blue dye at the interface was evaluated by simulating marginal microleakage. Results were analyzed through a macro photograph taken with professional camera evaluating the absence or presence of microleakage. Results: Analyzing the results obtained, both adhesive techniques obtained 75% of samples with microfiltration respectively. Obtaining a P=>0.05 value, which means that there are no statistically significant differences in terms of the collected data of microfiltration of both techniques. Conclusion: The results showed no statistically significant differences regarding marginal microfiltration, concluding that there is a similar performance regarding the adhesive strength of both techniques, which is demonstrated in the adhesive failure on the floor of the cavities of both groups.
