CASE SUMMARY
The aim of this study is to measure the amount of debris extruded into the periapical area during root canal irrigation with three types of needles: Max-I-Probe, NaviTip Fx, and IrriFlex.
The lowest amount of debris was observed with IrriFlex (and a penetration depth of 3 mm), while the highest amount was found with NaviTip Fx (and a penetration depth of 1 mm).
In conclusion, the study shows that needle design and penetration depth significantly influence debris extrusion. The use of more flexible needles and less apical penetration would be recommended to limit extrusion.
