| Abstract | ||
| Purpose: This study aimed to compare two self-ligating systems in terms of biological mediators Interleukin-I (IL1) and TNF-α found in the Gingival Crevicular Fluid (GCF) and the mechanical deterioration of Copper Titanium (CU-Niti) wires being used in this study. Subjects and Methods: Patients aged 18 to 25 years old were randomly assigned to one of three groups: Patients in Group I were treated with the conventional Foresta-dent system (control), patients in Group ІІ were treated by Ortho Pro-self-ligating brackets, and finally, group III patients were treated with Foresta-dent self-ligating systems. For each group, changes were assessed, and data management was performed by the statistical package for social sciences (SPSS) version 18. Post hoc and Wallis tests were used to compare the three groups. Results: The control group had the highest mean values in TNF-α and IL-1, followed by Foresta-dent and Ortho-pro self-ligating. The ANOVA test revealed no significant difference between group ІІ and group ІІІ. The two experimental groups had significantly lower values than the control group (P = 0.00). Conclusions: The two experimental groups recorded a significantly lower value in comparison to the control (p = 0.00). | ||
