ABSTRACT
Objective:
To verify the dental age of individuals with Angle Class II, division 2 malocclusion. Material andMethods:
The sample consisted of 200 panoramic radiographs of schoolchildren from the city of Fortaleza in the state of Ceará, in the northeast of Brazil. These radiographs were divided into two groups (N=100) a Control group comprising radiographs of patients with normal occlusion and a CIID2 group comprising radiographs of patients with an Angle Class II, division 2 malocclusion. The Demirjian method was used to identify dental age. All the radiographs were evaluated by a sole duly trained and calibrated technician. The Kappa coefficient for inter-annotator agreement was 0.98 based on the criteria of eruption stage of each tooth. Statistical analysis was performed using the Chi-squared test, Student's t-test and the Mann-Whitney test, with a level of significance of 5%.Results:
There was a significant statistical difference between the dental ages of the groups tested. The CIID2 group had a lower dental age than the control group, signifying late eruption in patients with an Angle Class II, division 2 malocclusion.Conclusion:
Patients with an Angle Class II, division 2 malocclusion had a lower dental age than patients with normal occlusion, suggesting that orthodontic treatment should be delayed. The first molars, second pre-molars and canines suffered late eruption.
