Ultrasonic versus hand filing of dentin: a quantitative study
Oral Surgery, Oral Medicine, and Oral Pathology
|January 1, 1980
Summary
Ultrasonic K-type files removed significantly more dentin than hand-powered files in a set time. This study compared ultrasonic and hand instrumentation for root canal dentin removal efficiency.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root canal preparation is crucial for endodontic treatment success.
- Effective dentin removal ensures thorough cleaning and shaping of the root canal system.
Purpose of the Study:
- To compare the dentin removal efficacy of ultrasonic K-type files versus traditional hand-powered K-type files.
- To evaluate the efficiency of ultrasonic instrumentation in a standardized root canal model.
Main Methods:
- Standardized root canals were prepared using both ultrasonic and hand-powered K-type files.
- Dentin removal was measured after a fixed period of instrumentation for both groups.
Main Results:
- Ultrasonic energized K-type files demonstrated significantly greater dentin removal compared to hand-powered K-type files.
- A higher volume of dentin was removed by ultrasonic instrumentation within the specified time frame.
Conclusions:
- Ultrasonic K-type files are more efficient in removing dentin during root canal preparation than hand-powered K-type files.
- Ultrasonic instrumentation offers a potential advantage for faster and more effective root canal cleaning and shaping.
