Hypothesis
The treatment protocol using Nd: YAP laser will be successful in removing or bypassing fractured instruments in teeth with minimal root curvature.
Conclusion
The Nd: YAP laser protocol is effective for removing fractured Ni-Ti files in teeth with minimal root curvature, achieving a 100% success rate.
Supporting Evidence
- The Nd: YAP laser achieved a 100% success rate in removing or bypassing fractured Ni-Ti files.
- 71.66% of cases resulted in bypassing the fractured instrument, while 28.33% achieved total elimination.
- The average time for bypassing or removing the broken files was 7.463 seconds.
- Chemical analysis showed significant presence of Ni and Ti residues in the irradiated canal area.
Takeaway
This study shows that a special laser can help dentists remove broken tools from teeth without causing damage, and it works really well.
Methodology
The study used Nd: YAP laser on 66 extracted teeth with notched Ni-Ti files, evaluating success based on complete removal or bypassing of the fractured instruments.
Limitations
The study only included teeth with minimal root curvature and did not compare different tooth types.
Participant Demographics
Human permanent teeth with minimal root curvature (less than 15 degrees).
