Motorized files overpower traditional K-files in pediatric root canal treatment: Study
It has been recently noted that motorized files extruded less debris and required less instrumentation time compared to traditional K-files, which could benefit paediatric patients with root canal treatment needs, as published in the Scientific Reports.
All endodontic instrumentation methods have a tendency to push debris through the apical foramen and into the periapical tissues. Such debris may consist of necrotic pulp tissue, dentin chips and bacteria. Extrusion of such debris may induce postoperative pain and inflammation and may inhibit periapical healing.
A growing body of literature has recognized the importance of reducing apically extruded debris. Estimating the root canal length just short of the apex, using an electronic apex locator, would also seem helpful in reducing the chance of extruding debris beyond the apex.
The extent of debris extrusion and the time required for instrumentation of the canals of primary teeth using motarized files have not been reported to date.
