ABSTRACT
Frequency dentition anomalies in children and adolescents according to different authors, ranging from rising 50.8 to 81%. Anomalies of dental systems lead to aesthetic and functional disturbances affecting the child's psyche, and often lead to the development of dental caries and periodontal diseases. So, the purpose of our study was to investigate the dynamics of dental caries' indexes in children with dentoalveolar anomalies under the influence of preventive measures. We observed 50 children aged 12, who were divided into four groups. The most effective prophylactic complex in terms of reduction of growth of caries (59.4%) was the one that involved the use of "Tooth Mousse" (applying to the surface of the teeth 5 minutes after eating one time a day, in the morning after brushing teeth), "Osteovit" (one tablet three times a day), "Pektodent--dentifrice? (dental cleaning powder twice a day--in the morning and evening). This complex creates conditions for increasing the resistance of hard dental tissues, resulting in low levels of intensity of caries in children.

OBJECTIVE: To estimate the magnitude of a change in the position of the hyoid bone when displacing the lower jaw during surgical treatment in patients with dentofacial abnormalities. MATERIAL AND METHODS: Fifty patients with dentofacial abnormalities (25 and 25 patients with distal and mesial occlusion, respectively) were examined and treated. All the patients underwent multislice spiral computed tomography before and 6 months after surgery. The authors developed linear quantities to analyze the position of the hyoid bone with respect to the skull base and cervical spine. The paired Wilcoxon signed-rank test was used. RESULTS: None of the examined groups was noted to have a statistically significant change in the distance between the basihyoid and the vertebral column, suggesting that the datum was moderately changed. No case of worse respiratory function was found. CONCLUSION: Our investigation has revealed that mandible displacement during orthognathic surgery causes no critcal change in the position of the hyoid bone and hence it has no significant impact on upper airway patency in this area.
