To evaluate the distance from the cementoenamel junction to pre alveolar crest pre and post-orthodontic treatment through Cone Beam Computed Tomography (CBCT). Methodology: We selected from a database of previous dental CBCT image data and subsequent orthodontic treatment of 30 patients who were diagnosed with malocclusion Angle Class I and mild to moderate crowding. The distance between the cementoenamel junction to bone crest of the buccal (n = 720) and palatal or lingual (n = 720) was measured in 24 teeth for each patient using a software tool specific Xoran version 3.1.62 (Xoran Technologies, Ann Arbor, MI, USA). Statistical analysis of pre and post-orthodontic treatment was assessed using the Wilcoxon test and significance level of p <0.05. Results: It was observed that at least one tooth of each patient had a face with increasing distance from the alveolar crest to orthodontic post-treatment cementoenamel junction. This increase was observed in 822 (57%) of the 1440 evaluated root faces. The buccal surface of lower central incisor showed the highest frequency of increasing distance (75%) and the palatal surface of maxillary lateral incisor presented the smallest (40%). It was found that the 1440 root faces previously assessed orthodontic treatment, 162 (11%) had distance from the cementoenamel junction to bone crest greater than 2 mm (alveolar bone dehiscence), and orthodontic aftertreatment faces evaluated, 279 (19 %). Conclusion: It can be concluded that there was a change of the distance from the junction amelocemetária alveolar crest orthodontic post-treatment; and distance greater than 2mm orthodontic pretreatment orthodontic 11% and 19% after treatment.
