The defensive mechanism of the human body includes a wide range of antioxidants (non-enzymatic and enzymatic) that can eliminate reactive oxygen species and prevent their harmful consequences on the host. Total antioxidant capacity (TAC) is a biomarker used to measure the antioxidant potential of body fluids and it may be the most relevant parameter for assessing the defense capabilities. Because of the cumulative effect of antioxidants, it is better to measure the combined activity of all the antioxidants (total antioxidant capacity) instead of measuring the activity of each agent separated. The aim of this study is to investigate the effect of different orthodontic appliances (fixed and removable-aligners) on salivary total antioxidant capacity and if is a correlation between TAC and oral injuries made by them. Three groups of subjects have been tested: one group of ten patients with metallic fixed appliances, one group of ten patients with aligners, and a control group consisting in ten subjects. 2,2-diphenyl-1-picrylhydrazyl (DPPH) method was used for TAC assessment and salivary samples were obtained from all individuals before treatment, at two weeks from the beginning, at one and two month of treatment. Also, it was quantified the presence of the injuries in the mucosa (clinical parameter). The result shows that different types of orthodontic appliances increase differently the TAC and seems to be influenced by the injuries. KeywordsTotal antioxidant capacity (TAC), DPPH method, orthodontic aligners, fixed appliances.To cite this article: MĀDĀLINA RA, SEBASTIAN M, AURELIANA C, VICTORIA B.Studies regarding salivary total antioxidant activity in different types of orthodontic treatement.

“…The effect of fixed orthodontic appliances on salivary pH has been investigated in previous studies without reporting which type of archwire ligation material was used. In an observational study, Zogakis et al [ 25 ] demonstrated a significant decrease in pH of saliva six weeks after fitting the appliance. Different results were presented by Peros et al [ 26 ] who reported an increase in salivary pH at 6, 12 and 18 weeks after fixed orthodontic therapy.…”

Salivary pH changes under the effect of stainless steel versus elastomeric ligatures in fixed orthodontic patients: a single-center, randomized controlled clinical trial

Background Fluctuations in pH of saliva during a prolonged treatment course influences the enamel demineralization progress, which is one of the complications of fixed orthodontic treatment. This randomized clinical trial aimed to evaluate and compare the short-term effects of stainless steel (SS) versus elastomeric (EM) ligatures on salivary pH in patients scheduled for fixed orthodontic treatment. Methods Seventy participants were enrolled in the study (54 female, 16 male) aged 19–36 years who met specific inclusion criteria. They were randomly selected and allocated into two equal groups through computer-generated randomization. All patients received fixed orthodontic treatment using conventional orthodontic brackets. Two commonly used archwire ligature methods were used: SS and EMs. An unstimulated (resting) salivary sample was collected before tying of the ligatures at T0 (baseline), 2 weeks, 6 (weeks), and 12 (weeks). Salivary pH was measured using a digital pH meter. The level of significance was set at p value < 0.05. Results The salivary pH level was stable between T0 and T1 (6.72 ± 0.14), then significantly and progressively increased from T1 to T2 (6.78 ± 0.13) and from T2 to T3 (6.81 ± 0.14) with (p < 0.05) in the SS group. In the EM group, the salivary pH level was significantly decreased in all follow-up periods; T0 (6.77 ± 0.16), T1 (6.72 ± 0.14), T2 (6.67 ± 0.13) and T3 (6.64 ± 0.13). Conclusion The EM ligatures showed a significant decrease in salivary pH to an unfavorable level, which increased the risk of enamel demineralization. Therefore, EMs as ligature material is preferably should not be recommended in patients with high caries index or inadequate oral hygiene. Trial registration ANZCTR.org.
