Determination of metal ion release from fixed orthodontic appliances – an in vivo study
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 5
Abstract
Aim: To determine the amount of Ni, Cr, Fe and Co in the saliva of patients being treated with fixed orthodontic appliances. Materials and Methods: A total number of 50 patients aged between 14-30 years of age were included in the study. Salivary samples were collected at four stages from the patient undergoing orthodontic treatment at the following times: T(0) – before insertion of the appliance, T(1) – 1 hour after insertion of the appliance, T(2) – 3 months after insertion of theappliance, T (3) - months after insertion of the appliance. Metal ion concentrations of saliva were evaluated using atomic absorption spectrophotometer (AAS). Statistical analysis: The results of the salivary ion concentrations were statistically evaluated using paired t test. A significance level of p>0.05 was considered as statistically insignificant. Results: It was noted that there was a significant (p<0.001) increase in concentration of metal ion in the saliva. Conclusion: The findings indicate that measurable amounts of nickel, chromium, iron and cobalt can be found in the saliva of the patients underwent fixed orthodontic treatment over a period of six months but the increase in values do not reach toxic levels. Further studies should be carried out to evaluate the effects of these changes over the course of the treatment.
