Examination Of Teeth Eruption In The Support Area Of The Romanian Subjects

Abstract

The aim of this study was to find out how many of the orthodontic patients had problems with the support area and if these could be identified and treated before any complications could occur; and also how the eruption process in the support area is influenced by these modifications. Materials and Methods: In this study, 62 patients, 34 girls (mean age: 10.03 years), and 28 boys (mean age: 9.67 years) were sampled from those who were prepared for treatment at the Orthodontic Department. Their panormaic radiographs were analyzed, especially the support area and the sequence of eruption of canine and bicuspids. Results: 56% of female and 43% of male subjects had an intact support area, while the rest showed modifications. 61% from patients with a good support area showed a normal sequence of eruption. However, when the second group was analyzed, 90% of them presented a modified sequence of eruption. In the first group in 84% of situations, even the second molar erupted normally, but, in the second group, 68% of the patients showed a modified sequence. Conclusion: Half of the investigated subjects showed some modifications in the support area. The number of male subjects with this situation is higher than that of the female subjects. When the support area develops normally, the sequence of eruption of permanent teeth is not modified, but, in those subjects who showed a changed support area, even the sequence of eruption was changed. In the same way, we can conclude about the sequence of eruption of the second molar: if the support area is normal, it will erupt after the second premolar; but if otherwise, some changes will occur in the process of eruption.
