Bacteriologic evaluation of ultrasonic root canal instrumentation
Oral Surgery, Oral Medicine, and Oral Pathology
|March 1, 1987
Summary
Ultrasonic instrumentation significantly enhanced root canal disinfection compared to hand methods alone. However, antibacterial dressings remain crucial between appointments for optimal bacterial reduction in infected root canals.
Area of Science:
- Endodontics
- Microbiology
Background:
- Root canal infections necessitate effective disinfection.
- Traditional hand instrumentation may leave residual bacteria.
Purpose of the Study:
- To clinically evaluate the antibacterial efficacy of ultrasonic instrumentation in infected root canals.
- To compare ultrasonic versus hand instrumentation for bacterial elimination.
Main Methods:
- Clinical evaluation of ultrasonic instrumentation.
- Use of 0.5% sodium hypochlorite as irrigant.
- No antibacterial intracanal dressing used between appointments.
Main Results:
- Ultrasonic instrumentation demonstrated superior bacterial elimination compared to hand instrumentation alone.
- Significant improvement in root canal disinfection was observed with ultrasonication.
Conclusions:
- Ultrasonic instrumentation enhances root canal disinfection procedures.
- Adjunctive antibacterial intracanal dressings are recommended for maximal bacterial reduction.
