No results posted yet for this study

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.

Conditions

  • Periapical Periodontitis
  • Root Canal Infection

Interventions

PROCEDURE

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

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.

PROCEDURE

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

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.
