Post-endodontic Access Cavity Cleaning Techniques

The contaminated dentine surface was scrubbed with a dry cotton pellet until no visible sealer remnants were observed

The contaminated dentine surface was scrubbed with a 70% ethanol-saturated cotton pellet for 7 seconds

The contaminated dentine surface was scrubbed with a 70% ethanol-saturated cotton pellet until no visible sealer remnants were observed.

After the contaminated dentine surface scrubbing with an 70% ethanol-saturated cotton pellet until no visible sealer remnants were observed, air polishing was performed for 10 seconds using the AquaCare Twin device (Velopex, UK). Sodium bicarbonate powder (Velopex) was applied at a pressure of 2 bar, with a medium media flow and 17.5% ethanol-saturated solution (AquaSol, Velopex). The standard tip was positioned approximately 5 mm from the dentin surface and moved in a vertical (up-and-down) direction during the procedure. The application time and parameters were determined in consultation with the manufacturer due to the lack of previous clinical studies using the AquaCare device for this purpose.

The contaminated dentine surface was scrubbed with a 70% ethanol-saturated microbrush for 7 seconds

The contaminated dentine surface was scrubbed with a 70% ethanol-saturated microbrush until no visible sealer remnants were observed.

Air abrasion was performed for 10 seconds using the AquaCare Twin device (Velopex, UK). Aluminium oxide particles (53 µm, Velopex) were applied at a pressure of 2 bar, with a medium media flow and 17.5% ethanol-saturated solution (AquaSol, Velopex). The standard tip was positioned approximately 5 mm from the dentin surface and moved in a vertical (up-and-down) direction during the procedure.
