NCT06507592

Brief Summary

The purpose of this prospective observational study is to evaluate the differences in oxidative-reductive processes and the degree of inflammation in saliva during treatment with conventional brackets and clear aligners. The evaluation will be performed by determining the salivary values of Total oxidant status (TOS), total antioxidant status (TAS) and 8-hidroxy-2'-deoxyguanosine (8OHdG).

Outcome Measures

Primary Outcomes (1)

  • Oxidative-reduction and inflammation

    The Total Antioxidant Status (TAS) in saliva samples was measured using a N 2 615700-1KIT Total Antioxidant Status Assay Kit, a colorimetric assay for antioxidant levels in serum or plasma. The Total Oxidant Status (TOS) was measured with a CS0790-1KT Antioxidant Assay Kit, which includes all necessary reagents to measure total antioxidant capacity in plasma, serum, urine, saliva, cells, and tissue lysates. It also measures the radical cation (ABTS+) scavenging capacity. The 8-Hydroxy-2'-deoxyguanosine (8-OHdG) and Tumor Necrosis Factor-α (TNF-α) levels were determined using an E-EL-H0109 HUMAN TNF-ALPHA ELISA KIT, which detects protein levels quantitatively in serum, plasma, or cell lysate supernatants.

Study Arms (2)

Fixed Appliances (FA)

OTHER

13 patients with fixed appliances, between 10 and 18 years of age, with good oral hygiene and without gingival inflammation, has been recruited

Diagnostic Test: Saliva samples collection

Clear Aligners (CA)

OTHER

13 patients with clear aligners, between 10 and 18 years of age, with good oral hygiene and without gingival inflammation, has been recruited

Diagnostic Test: Saliva samples collection

Interventions

The first sample of saliva was be taken before the start of the treatment and considered as the control sample (T0); the second sample was be taken one month after the start of the treatment (T1) and the third one after three months (T2).
