Evaluation of Mixed-Dentition Employing Three Different Methods: Plaster, Digital, CBCT and Directly Measurements of Non-Erupted Permanent Teeth in CBCT
Journal Title: International Journal of Dentistry and Oral Science (IJDOS) - Year 2015, Vol 0, Issue 1
Abstract
This study was to evaluate the Moyers method for mixed-dentition, in dental plaster models (DP), dental digital (DD), in dental tomography models (DT) generated using Cone-beam computer tomography (CBCT) with the possibility to measure directly unerupted permanent teeth with assessing the diameter of intra-osseous (DPDT), and compare the results with those. Material and Methods: The sample consisted of 20 healthy children, 9, 5 years, with mixed dentitions. The measurements were performed on DP, DD, DT, DPDT, using the reference of Moyers analysis with 75% and 95% error probability. Results: We obtained significant differences between most measures, although they correlated and reliability demonstrating that the measures were related and could be used clinically, (p-value < 0.005 and p-value <0.016 , in Manova e Bartlett test and 95% intervals of Bonferroni reliability for standard deviations to Moyers 75% and 95%, respectively). There is a significant association in the average for discrepancies between DP and DD (p<0.0018), DP and DT (p<0.031) , DP and SDPT (p<0.04). There was a positive Pearson correlation between DP and DD (0.694533), DP and DT (0.603836), DP and SDPT (0.602709) and DT and SDPT (0.998076). Conclusion: DP and DT can be used with the parameters of Moyers analysis with 75% and 95% probability of error. There were significant differences between DP and DD, and DT and DPDT. For the application of analysis Moyers 75%, the differences between techniques was positive, and that within the orthodontic planning could not be clinical difference.
