Efficacy of Minimal vs. Conventional Apical Preparation With Passive Ultrasonic Irrigation in Reducing Intracanal Bacteria: A Clinical Study

Medipol University·interventional·Posted Jun 5, 2025·Updated Jun 5, 2025

In Brief

A clinical study evaluating Root canal shaping with One Curve Mini #25/0.4 and passive ultrasonic irrigation and Root canal shaping with One Curve Mini #35/0.4 and passive ultrasonic irrigation for Periapical Periodontitis and Root Canal Infection. Completed, enrolled 24 participants across 1 site.

Detailed Summary

This study evaluates intracanal bacterial load in molar teeth with chronic apical periodontitis before and after root canal shaping with two different apical enlargement sizes and ultrasonic irrigation activation.

Interventions

Root canal shaping with One Curve Mini #25/0.4 and passive ultrasonic irrigationprocedure

Participants in this group underwent root canal shaping using a One Curve Mini #25/0.4 rotary file. After mechanical preparation, passive ultrasonic irrigation (PUI) was performed using a VDW Ultra device with an IRRI S 21/25 ultrasonic tip. Irrigation was activated with 3% sodium hypochlorite (NaOCl) in three 20-second cycles, using 1 ml per cycle. The ultrasonic tip was placed 2 mm short of the working length without contacting canal walls.

Root canal shaping with One Curve Mini #35/0.4 and passive ultrasonic irrigationprocedure

Participants in this group underwent root canal shaping using a One Curve Mini #35/0.4 rotary file. The same passive ultrasonic irrigation protocol was applied as in Arm 1, using 3% NaOCl in three 20-second cycles with 1 ml per cycle. The ultrasonic tip was positioned 2 mm short of the working length without contacting the canal walls.
