Clinical and laboratory assessment the levels of oral hygiene, total protein, hydrogen sulfide and nitrogen metabolites in oral fluid in the development of inflammatory complications during orthodontic treatment of children.

Objective: Introduction: Orthodontic treatment often causes inflammatory diseases in the oral cavity. The aim: То іncrease the effectiveness of prevention of inflammatory complications in the provision of orthodontic care to children with dentomaxillary anomalies using nonremovable orthodontic devices on the basis of study of clinical and biochemical parameters.

Patients And Methods: Materials and methods: The study was conducted among 100 patients divided into two groups: control and experimental group 2 (50 patients in each). The control group included healthy children without dento-maxillary anomalies. The second group were children aged 9-15 years with dento-maxillary anomalies which used non-removable (bracket systems) orthodontic devices. The oral fluid was collected at the beginning of the medical application of orthodontic devices (at the first day of treatment in the clinic) and after 3 and 6 months of treatment. The study included the definition of the oral hygiene degree by using the Green-Vermillion index (OHI-S), the modified Fedorov-Volodkin's and Siness-Loe index, the determination of hydrogen sulfide and total protein levels, the content of nitrogen metabolites in the oral liquid.

Results: Results: The use of non-removable orthodontic devices led to signs of inflammation in the oral cavity. This was accompanied by a deterioration of the oral hygiene, increase the total protein, hydrogen sulfide and nitrogen metabolites levels in the oral fluid.

Conclusion: Conclusions: Complex accounting is required of keeping oral hygiene in good condition, level determination of total protein, hydrogen sulfide and nitrogen metabolites for the prevention of the development of inflammatory diseases in the provision of orthodontic care.
