An in vitro comparison of adhesive techniques and rotary instrumentation on shear bond strength of nanocomposite with simulated pulpal pressure

Abstract: Aim:The aim of this study is to evaluate the shear bond strength of composite to tooth using different adhesive techniques and rotary instruments under simulated pulpal pressure.Materials and Methods:Sixty extracted human molars were randomly divided into two groups of 30 samples each (group I and II), according to the adhesive technique followed (i.e. total etch and self etch groups). Each group was further divided into two sub-groups (Sub-groups A and B) of 15 samples each according to the cutting instrument… Show more

“…[ 10 13 ] C factor for dental restorations typically ranges from 0.1 to 5, with higher values indicating a greater likelihood of high interfacial stress. [ 12 ] C factor in class II restorations is 2, and the restorations are susceptible to adhesive breakdown during curing. Oblique incremental technique with increment of 1-1.5 mm thickness produce lowest C factor.…”

“…Si los instrumentos no realizan el corte y la remoción adecuada del barrillo dentinal, la mayor densidad dicultará su disolución por medio del ácido y, por tanto, menor área de contacto entre el adhesivo y el material restaurador. En este estudio se encontraron algunas diferencias signicativas en el estado nal de las 4 marcas evaluadas, tal y como se observa en los resultados (14).…”

“…La forma y adhesión de los granos de diamante en los vástagos son los factores responsables de la eciencia de corte del instrumento (18): serán determinantes en la calidad de la preparación. Las fresas de diamante, al ser comparadas con otros elementos de corte (19), han resultado tener mejor fuerza adhesiva (14) y resistencia a la tensión de la interfaz de la supercie del diente y el material restaurativo. Lo anterior es importante en la práctica clínica, ya que el estado del instrumento no estará relacionado solamente con la vitalidad del diente, sino con la humectación y óptimo sustrato para procesos de rehabilitación adhesiva.…”
