Summary
Early radicular flaring eases root canal instrumentation but does not significantly affect apical transportation compared to late flaring when using balanced force techniques. Both methods show similar outcomes for apical transportation.
Area of Science:
- Endodontics
- Dental Morphology
- Biomaterials
Background:
- Root canal instrumentation aims to clean and shape the canal system.
- Apical transportation is a critical factor in endodontic treatment success.
- Balanced force instrumentation is a widely used technique for shaping root canals.
Purpose of the Study:
- To compare the effects of early versus late radicular flaring on apical canal transportation.
- To evaluate the influence of flaring timing on instrumentation ease using balanced force.
- To assess apical transportation in curved root canals treated with different flaring strategies.
Main Methods:
- Sixty-six human teeth with 20-65 degree curvatures were used.
- Teeth were divided into two groups: early radicular flaring and late radicular flaring.
- Balanced force instrumentation was employed, followed by radiographic assessment of apical transportation.
Main Results:
- Early radicular flaring significantly improved the ease of instrumentation.
- No statistically significant difference in apical canal transportation was observed between the early and late flaring groups.
- Both techniques resulted in comparable apical transportation outcomes.
Conclusions:
- The timing of radicular flaring does not impact apical transportation when using balanced force instrumentation.
- Early flaring enhances procedural efficiency without compromising apical control.
- Clinicians can consider early flaring for improved instrumentation ease in endodontic procedures.
