RESUMO
OBJECTIVE: The aim: To increase the efficiency of diagnosis and planning of orthodontic treatment of patients with interarch relationship of teeth and teeth position anomalies by developing an optimal algorithm for radiological research using cone-beam computed tomography (CBCT), teleroentgenography (TRG), orthopantomography (OPG). PATIENTS AND METHODS: Materials and methods: 1,460 patients with interarch relationship of teeth and teeth position anomalies were examined at the Department of Radiology of the P. L. Shupyk National Healthcare University of Ukraine. The cohort of 1460 examined patients was divided by gender: 600 men (41.1%) and 860 women (58.9%) aged 6 to 18 years and 18 to 44 years. Distribution of patients was held by the number of the primary pathology signs and the number of concomitant pathology signs. RESULTS: Results: The choice of the optimal radiological examination of patients is influenced by the number of signs of the main and accompanying pathology. The risk of secondary examination of the patient with a mathematical method of choosing the optimal diagnostic technique is determined.The risk of secondary radiological examination of the patient was determined at a marginal probability of 88% (at a higher value, the model predicts a repeat visit). CONCLUSION: Conclusions: The developed diagnostic model shows that when determining the Pr-coefficient of 0.79, it is recommended to carry out OPTG and TRG. With indicators of 0.88, the recommendation is to conduct CBCT in the age groups 6-18 and 18-44 years.
