    Abstract:
    OBJECTIVE:: The purpose of this study was to evaluate the dental radiographic characteristics as described in 40 records of patients with panoramic radiography. MATERIAL AND METHODS:: The patients were in the range of 6-17 years old, and were divided into two groups (20 subjects who were compatible with the normality standard and 20 individuals diagnosed with the FXS), which were matched for gender and age. Analysis of the panoramic radiographic examination involved the evaluation of dental mineralization stage, mandibular angle size, and presence of dental anomalies in both deciduous and permanent dentitions. RESULTS:: The results of radiographic evaluation demonstrated that the chronology of tooth eruption of all third and second lower molars is anticipated in individuals with FXS (p<0.05). In this group, supernumerary deciduous teeth (2.83%), giroversion of permanent teeth (2.31%), and partial anodontia (1.82%) were the most frequent dental anomalies. In addition, an increase was observed in the mandibular angle size in the FXS group (p<0.05). CONCLUSION:: We conclude that knowledge of dental radiographic changes is of great importance for dental surgeons to plan the treatment of these individuals.
