Influence of orthodontic treatment with removable devices in children on the properties of oral fluid

Abstract

Relevance. The present article provides data regarding changes in the oral cavity during orthodontic tratment with custom-made removable appliances. Purpose. To study the condition of the oral cavity in children aged 7-12 with dentoalveolar abnormalities during treatment with removable orthodontic appliances.Materials and methods. 110 patients aged 7-12 were examined in Nakhodka, Russia. Group I – control (34 subjects) with no dentoalveolar pathology. Group II – children with dentoalveolar pathology (74 subjects), undergoing orthodontic treatment. Besides clinical examination the following laboratory tests were taken, namely: saliva viscosity, saliva PH, saliva buffer capacity, microcrystallography of saliva. Type III prevailed in 60% of cases. Results. Caries intensity during orthodontic treatment was detected to increase up to 8.32 ± 0.28 in comparison with control group 6.57 ± 0.22 (p < 0.05). Hygiene rate decreased in experimental group to 2.8 ± 0.08, in comparison with controls – 1.40 ± 0.02 (p < 0.05). Salivary PH decreased during orthodontic treatment. Microcrystallization type III of saliva prevailed in 60% of cases.Conclusions. The study revealed strong relationship between orthodonotic treatment with removable appliances and physicochemical properties of mixed saliva r = 0.95 (p < 0.05). Appropriate approach and timely preventive measures can help correct oral condition in orthodontic treatment. Despite changes in oral fluid composition, esthetic and functional result of treatment with orthodontic customized removable appliances was high.
