Apical Extrusion of Debris Following Root Canal Preparation With ProTaper Universal, Reciproc Blue, and WaveOne...

Area of Science:

• Endodontics
• Dental Materials Science

Background:

• Apical extrusion of debris during root canal cleaning and shaping can lead to inflammation and treatment failure.
• Minimizing debris extrusion is essential for successful endodontic outcomes.

Purpose of the Study:

• To compare the amount of apically extruded debris produced by three different rotary root canal instrumentation systems: ProTaper Universal (PTU), Reciproc Blue (RB), and WaveOne (WO).

Main Methods:

• An in vitro experimental study using 45 single-rooted teeth.
• Teeth were instrumented using PTU, RB, or WO systems.
• Apically extruded debris was collected and weighed to quantify extrusion levels.

Main Results:

• The WaveOne (WO) system produced the least amount of apically extruded debris (9.087 ± 2.004 µg).
• ProTaper Universal (PTU) resulted in moderate debris extrusion (13.809 ± 2.424 µg).
• Reciproc Blue (RB) showed the highest debris extrusion (19.177 ± 7.661 µg), with statistically significant differences between all groups (p < 0.001).

Conclusions:

• All tested rotary systems caused apical debris extrusion.
• The WaveOne (WO) system demonstrated significantly less apical debris extrusion compared to both ProTaper Universal (PTU) and Reciproc Blue (RB) systems.
