Background: Through assessment of the midpalatal suture morphology, it was found out that it is possible to minimize the failure of rapid maxillary expansion in adolescent and young adult patients. However, it is not possible to obtain routine CBCT of every patient, and especially those without any diagnostic need (e.g., impacted tooth, cyst). Hence the present study is taken up to correlate Angelieri et al CBCT classification of midpalatal suture morphology with routinely used various skeletal maturity indicators like Second molar calcification stages by Demirjian, CVMI stages by Hassel and Farman and MP3 stages by Hagg and Tarranger which are available as a part of the routinely obtained diagnostic records for patients requiring maxillary expansion.
Methods: The study was performed using CBCT of axial view of maxilla, Orthopantomograms, lateral cephalograms, Intra oral periapical radiographs of Middle phalanx of third finger obtained from 25 patients aged between 10 to 25 years seeking orthodontic treatment.
Results: The results showed that Correlation between Cervical vertebrae maturation stages and CBCT (midpalatal suture) stages values showed statistically highly significant correlation(p<0.001). Correlation between middle phalanx of third finger stages and CBCT (midpalatal suture) stages values showed statistically highly significant correlation(p<0.001). Correlation between second molar calcification stages and CBCT (midpalatal suture) stages values showed statistically significant corelation(p<0.008)
Conclusion: Among developmental age indices, CVMI and MP3 Showed highly significant correlation, suggesting that they can be useful in assessing maturation of the midpalatal suture.
