Root Resorption after Piezocision and Micro-osteoperforations in Canine Retraction: A Systematic Review and...

Area of Science:

• Orthodontics
• Periodontology
• Dental Implantology

Background:

• Canine distalization is a common orthodontic procedure.
• Root resorption is a potential adverse effect of orthodontic tooth movement.
• Micro-osteoperforations (MOPs) and Piezocision are techniques used to accelerate orthodontic tooth movement.

Purpose of the Study:

• To systematically review and compare the incidence of root resorption between MOPs and Piezocision during canine distalization.
• To evaluate the safety of MOPs and Piezocision regarding root resorption in orthodontic treatment.

Main Methods:

• A systematic literature search was performed across major databases (PubMed, Web of Science, Scopus, EMBASE, Cochrane Library).
• Six randomized controlled trials were included in the meta-analysis.
• Data were analyzed using the weighted mean difference (WMD) with 95% confidence intervals, employing a random-effects model.

Main Results:

• Micro-osteoperforations (MOPs) showed no statistically significant difference in root resorption compared to the control group (WMD = -0.02; 95% CI: -0.06 to 0.02; p = 0.37).
• Piezocision also demonstrated no statistically significant difference in root resorption compared to the control group (WMD = -0.41; 95% CI: -0.98 to 0.15; p = 0.15).
• Neither MOPs nor Piezocision were associated with adverse events related to root resorption in canine retraction patients.

Conclusions:

• Micro-osteoperforations (MOPs) and Piezocision do not appear to increase the risk of root resorption during canine distalization.
• These adjunctive techniques are considered safe concerning root resorption in orthodontic treatment.
• Further research may explore long-term effects and patient-specific factors influencing root resorption.
