dc.abstract.en Background: The assessment of bone age comprises the basic element of orthodontic diagnostics as it enables the recognition of deviations from normal growth, determines the choice of treatment, helps determine the appropriate moment to begin treatment, establish prognosis and plan a retention strategy. In order to make an assessment of skeletal maturity possible in a single examination, radiological methods were adopted. The following characteristics are evaluated on a radiograph: the appearance, size and shape of ossification centers, the width and the shape of growth cartilage and the degree of fusion between diaphyses and epiphyses. In order to assess the maturity of bones, hand-wrist radiographs were introduced in the second decade of the 20th century. Bone age assessment of bone age could also be made based on an analysis of a morphological maturity of cervical vertebrae utilizing cephalometric radiographs. Objective: The objective of the study was to evaluate the correspondence between bone age assessments made from hand-wrist radiographs and those from cephalometric radiographs. Material/Methods: In order to fulfill the objectives, hand-wrist radiographs as well as cephalometric radiographs of 30 patients (15 girls and 15 boys) between 10 and 17 years of age were collected. Bone age of hand, wrist and cervical spine was assessed. Bone age on hand-wrist radiographs was evaluated using the Björk method, whereas cephalometric radiographs were analyzed by the Baccetti et al.method. Results: A strong and statistically highly significant (r=0.98; p<0.00001) Pearson's correlation was found between bone age assessed from hand-wrist radiographs using Björk's method and bone age assessed from cephalometric radiographs using the method by Baccetti et al. Conclusions: The analysis of cervical vertebrae in cephalometric radiographs appears to be the most desirable method of bone age assessment. Performing the analysis on routinely taken cephalograms eliminates the need for additional exposure to X-ray radiation and shortens the duration of examination. pl
