Abstract:

Objective

To analyze the effect of corticotomy on root resorption in orthodontic treatment by comparing the differences between corticotomy assisted orthodontic treatment and conventional orthodontic treatment in the existing studies.

Methods

PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang database and SinoMed were searched from January 1st, 2000 to January 27th, 2024 for randomized controlled trials on the effect of corticotomy on root resorption after orthodontic treatment. Quality assessment, data input and meta-analysis of the included studies were performed using RevMan 5.4.1 and Stata 18 software.

Results

According to the inclusion criteria, a total of 12 studies were included for the meta-analysis. The results showed that corticotomy assisted orthodontic treatment manifested the decrease in root resorption [WMD = -0.14, 95% CI = (-0.23, -0.04) , Z = 2.86, P = 0.004, I2 = 47%], compared with the control group receiving conventional orthodontic treatment, and the difference was statistically significant. Subgroup analysis was carried out to explore the source of heterogeneity, indicating that flap surgery was the main source of heterogeneity. There was no statistical difference between subgroups according to tooth extraction condition and tooth position.

Conclusion

Root resorption can be effectively reduced after corticotomy assisted orthodontic treatment.
