[Markers of dental children`s health in the application of therapeutic orthodontic equipment].
INTRODUCTION: Treatment of teeth anomalies using removable and non-removable orthodontic devices in children leads to complications such as caries, gingivitis, periodontitis, oral mucosa hyperplasia. Etiopathogenetical of these diseases can be associated with biochemical changes in the composition of saliva.
AIM: To determine the activity of lysozyme and amylase in oral fluid in children when using a fixed and removable orthodontic devices.
MATERIALS AND METHODS: Amylase and lysozyme were studied in oral fluid. Analyzed the biochemical composition of the freshly samples of oral fluid that was obtained in the control, experimental group 1 and 2 (children ages 7-18 years, which were used medical non-removable and removable orthodontic devices). Saliva was collected at the beginning of the therapeutic use of orthodontic devices (the first day of treatment), on 3 and 6 months of treatment. Assessment of lysozyme activity was carried nephelometric method on the ability of lysozyme to dissolve indicator organism Micrococcus lysodeicticus. To construct a calibration graph using dry lysozyme company Sigma. Salivary amylase activity was determined by hydrolysis of starch. The results were subjected to statistical analysis by standard methods. Data processed using software packages applied statistical analysis Statistica 6.0, Microsoft Excel, 2003.
RESULTS: The use of a fixed and removable orthodontic equipment led to a decrease in saliva amylase, major changes are observed on the 6th month of treatment. The activity of lysozyme in saliva decreased the mostin patients with a permanent equipment. Major changes were also recorded on the 6th month of treatment.
CONCLUSIONS: Complications of orthodontic treatment teeth anomalies in children (caries, gingivitis, periodontitis) caused by changes in the biochemical composition of saliva. For the prevention of the emergence and development of these complications is necessary to control the level of amylase and lysozyme in the mouth.
