Hypothesis
Does the use of a novel cyclical force device in orthodontics produce root resorption as shown on 3D images?
Conclusion
The study found no statistically significant changes in root lengths at the end of treatment compared to the start when using the novel device.
Supporting Evidence
- No significant differences were noted between roots of anterior and posterior teeth.
- No clinically significant changes between root lengths were noted above 0.5 mm.
- 14 out of 17 subjects completed the study.
Takeaway
The study tested a new device to see if it would hurt teeth during braces treatment, but it didn't cause any noticeable damage.
Methodology
Patients used a cyclical force device for 20 minutes daily over six months, with CBCT images taken at the start and end of the study.
Limitations
The study had a small sample size and only included subjects who were first-time brace users.
Participant Demographics
Mean age of participants was 20.3 years, with ages ranging from 12.1 to 56.6 years.
