| Abstract: |
Introduction: Assessment of maxillary transverse discrepancy requires an accurate tool in order to implement the appropriate treatment plan. Aim: To evaluate the accuracy of Pont's Index in confirming a transverse maxillary deficiency by comparing its results with the corresponding results yielded by the University of Pennsylvania CBCT analysis. Material and methods: The study was performed on dental casts and CBCT's of 60 randomly selected patients by adopting a cluster sampling method. The results of Pont's Index and University of Pennsylvania CBCT analysis were analyzed through McNemar's test using Excel Data Analysis, and the accuracy indicators for Pont's Index were computed using MedCalc Ltd. Results: Mc Nemar's test revealed a p-value of 0.85. The accuracy indicators of Pont's Index were: sensitivity: 69%; specificity: 16.6%; positive predictive value: 65%; negative predictive value: 18.75%; positive likelihood ratio: 0.83; negative likelihood ratio: 1.86; and accuracy: 53.28%. Conclusion: Due to the fact that CBCT is not used on a daily basis and Pont's Index has a relatively high sensitivity (69%) making it suitable to detect patients with a narrow maxilla, assessment of the maxillary deficiency on CBCT can be recommended for cases were the midpalatal suture maturation should be evaluated.
