Objective: Thus, this research aimed to evaluate the conformity degree amongst orthodontists regarding morphological analysis of lateral teleradiography in order to determine the craniofacial growth tendency. Material and methods: Three lateral radiographs of children aged between 7 and 11 years old and with class I skeletal and dental relationship were selected. Each lateral radiograph featured a different type of growth tendency (vertical, balanced or horizontal), which were confirmed by tracing the cephalogram and measuring the SN.GoGn, SN.Gn and FMA angles and the VERT index. The lateral radiographs were cut in the regions of mandibular head, mandibular ramus, gonial angle, mandibular plane, antegonial notch, mandibular symphysis, occlusal plane and interincisal angle. These cuts as well as the complete versions of the lateral radiographs were randomly included into an electronic questionnaire applied for 105 orthodontists that were divided into three different groups: group 1 was composed of orthodontists with up to 1 year as specialists, group 2 was constituted by orthodontists whose graduation was concluded in between 1 and 5 years, and group 3 was formed by orthodontists who have graduated in more than 5 years. At first, the orthodontists were not aware of which cut belonged to each radiograph and so the orthodontists should define the growth tendency suggested by the images. The conformity degree was measured using Intraclass Correlation Coefficient (ICC) and the comparisons between the groups and between growth tendencies were evaluated using Kruskal-Wallis test, followed by the post test of Dunnet. Results: The orthodontists demonstrated a poor degree of conformity for the jaw head in the tendency of horizontal growth. Nevertheless, an almost-perfect conformity degree was observed for the gonial angle and mandibular plane in the vertical tendency as well as for the antegonial notch and mandibular plane in the tendency of horizontal growth and also when all anatomic structures were analyzed in the complete lateral radiographs. Therefore, significant discrepancies in the morphological analysis performed by the studied groups were not observed. Conclusion: In conclusion, the orthodontists demonstrated different degrees of conformity in the morphological analysis of lateral radiograph depending on the anatomical structure and the analyzed tendency of craniofacial growth.Acesso AbertoOrtodontiaCefalometriaCrescimento e desenvolvimentoDiagnósticomasterThesisCNPQ::CIENCIAS DA SAUDE::SAUDE COLETIVA
