A study to evaluate the proximity of anterior border of incisive canal to maxillary central incisors roots in skeletal class i and skeletal class ii malocclusion using cbct

Introduction: Determination of the three-dimensional (3D) position of the maxillary incisors is an integral part of orthodontic diagnosis and treatment planning. The contact of maxillary central incisor root with the incisive canal after maximum retraction was associated with apparent root resorption raising potent complications. Aims & Objectives: To evaluate the relative position of incisive canal with regard to maxillary central incisors roots using CBCT in skeletal class I and skeletal class II malocclusion. To compare the proximity of anterior border of incisive canal to maxillary central incisors roots in Pre treatment stage between skeletal class I and skeletal class II malocclusion using CBCT. To compare the proximity of anterior border of incisive canal to maxillary central incisors roots before strap up and at pre-finishing stage in skeletal class I and skeletal class II malocclusion using CBCT. Material & Methods: Total of 30 patients were divided into two groups: Group A: 15 skeletal class-I patients, Group B: 15 skeletal class-II patients. Both pre and post treatment CBCT images of both the groups were taken to evaluate the anterioposterior distance from incisive canal to maxillary central incisors roots. Results: All the study parameters showed a slight decrease from the pre- treatment to post-treatment time points and the changes in Rm-canal (P value 0.05) and CI root (P value 0.005) mean values with treatment were statistically significant. Conclusion: Anteroposterior distance between maxillary central incisor roots and incisive canal in both skeletal class I and class II groups does not show any significant differences.
