Table 3 Qualitative analysis results of root length
Study ID | Groups | Surgical intervention | Outcomes | Results | Root length | Conclusion |
|---|---|---|---|---|---|---|
Ahn (2016) [37] | T: PAOO n = 15 C: Conventional Orthodontics n = 15 | T1: Full-thickness flaps were elevated, vertical interproximal cortical bone incisions were created with bone grafting. T2: traditional orthodontic treatment | root length | Root length decreased in T Group by 0.6 mm vs. 0.67 mm in C Group. There were no significant differences in their changes between the groups. |
| PAOO in presurgical orthodontic treatment does not increase the risk of root resorption. |
Ma (2023) [31] | T: PAOO n = 18 C: Conventional Orthodontics n = 18 | T1: Full-thickness flaps were elevated, and with a vertical releasing incision added at the premolar area, circumscribing the corticotomy with bone grafting. T2: traditional orthodontic treatment | root length | Root length decreased in T Group by 1.16 mm vs. 0.82 mm in C Group. There were no significant differences in their changes between the groups. |
| There was no statistically significant difference between the groups in regards to root resorption. |
