Reciprocation - benefits
NiTi instruments in reciprocation
Plastic phase
• Simplicity
• Ony one instrument for one tooth
• Sterile – single use
• Safety
• Minimized risk of fracture
• No risk of contamination
• Users friendly
Reciprocation - benefits
• Regressive taper

RECIPROC®
Basic rules of power driven endodontics -
reciprocation
• Movement in amplitudes: up/down 3 mm
• Cleansing of instruments each 3amplitudes
• Reach the apical constriction and go out !
