Modern machine-assisted root canal treatment using a reciprocating system and endometry has significantly enhanced efficiency and precision in endodontics. The reciprocating system employs special files that move alternately forward and backward, increasing flexibility and adaptability in canal preparation. This technique minimizes the risk of instrument breakage and allows for a gentler treatment of the tooth tissue. This approach is complemented by endometry, a method for accurately determining root length through electrical measurements. This combination of reciprocating motion and precise length measurement optimizes the cleaning and shaping of the root canal, contributing to a higher success rate of the treatment.
