Summary
Piezocision, a procedure used in orthodontics, significantly increased root resorption and damage by 110% compared to controls. Careful application is advised to prevent iatrogenic root damage during orthodontic treatment.
Area of Science:
- Orthodontics
- Periodontology
- Biomaterials
Background:
- Orthodontically induced inflammatory root resorption (OIIRR) is a common side effect of orthodontic treatment.
- Piezocision is a surgical technique used to accelerate tooth movement.
Purpose of the Study:
- To investigate the effect of piezocision on OIIRR.
- To evaluate the incidence of iatrogenic root damage associated with piezocision.
Main Methods:
- A split-mouth study design was used with 14 patients.
- Piezocision was applied to one side, with the contralateral side serving as the control.
- Microcomputed tomography was used to assess root resorption after 4 weeks of orthodontic force application.
Main Results:
- Piezocision significantly increased total root resorption by 44% (P=0.029).
- Piezocision-related iatrogenic root damage was observed in 5 patients.
- Combined orthodontic and piezocision treatment resulted in a 110% average increase in volumetric root loss (P=0.005).
Conclusions:
- Piezocision may enhance OIIRR and cause iatrogenic root damage.
- Careful application of piezocision is recommended to minimize risks to adjacent roots.
- The regional acceleratory phenomenon initiated by piezocision may contribute to increased root resorption.
