Repair of Vertically Fractured Root

"The canal walls were etched with 37% orthophosphoric acid for 30 seconds with use of a microbrush.~The primer was applied on the wet canal walls, with a microbrush several times, after checking by drying the canal, that the appearance of the dentine was shiny and not opaque or chalky.~The next step was the application of bonding with a microbrush, blowing in the fracture line to make sure it is not loaded with bonding.~Flow composite was used to make it penetrate the fracture line with the help of a 0.06 mm k-file.~The canals were filled with dual composite parts more deeply, light cured at the canal entrance and pulp chamber; the following phase was the coronal restoration with a sandwich technique, covering the cusp with composite."
