Root Canal Preparation: Cleaning and Shaping

Shaping and disinfection are the cornerstones of root canal treatment (endodontics). Shaping prepares the space for the filling material, while disinfection eliminates bacteria from the root system. Both processes occur simultaneously to ensure clinical success and healing. 1. Shaping (Biomechanical Preparation) The goal is to give the canal a conical and continuous shape that respects its original anatomy, facilitating cleaning and three-dimensional sealing. -Instrumentation: This is performed using manual or rotary files (generally nickel-titanium), accompanied by constant irrigation. -Techniques used: Strategies such as Crown-Down (from coronal to apical) and Step-Back are employed to remove necrotic or inflamed pulp tissue without pushing debris toward the apex. 2. Disinfection and Chemical Cleaning Instrumentation alone cannot clean anatomical irregularities or destroy all bacterial biofilm. -Irrigation: Use of antibacterial solutions and organic tissue solvents, such as sodium hypochlorite and EDTA, to remove dentin debris and eliminate bacteria such as Enterococcus faecalis. #dentist #shorts #doctor #medical #dentalcare #braces #invisalign #tooth #smile #smiley #wisdomtooth #wisdomteeth #pain #infection #satisfying #satisfyingvideo #implant #implants #oddlysatisfying
