Studies regarding salivary total antioxidant activity in different types of orthodontic treatement

Abstract

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.

Diagnostic Role of Saliva in Oral Cancers

“…Saliva is proving to be a noninvasive diagnostic fluid alternative [6], containing almost all the compounds found in blood and also oral cells and tumoral cells. It has constant contact with malignant and premalignant lesions [7,8]. Saliva collection doesn't require trained medical personnel or special medical devices thus making it suitable for everyday screening usage in dental offices [9,10].…”
