Abstract
Aim: This study proposes to correlate, by means of cone beam computed tomography (CBCT), the periodontal tissues measurements, of anterosuperior teeth, with the presence/absence of altered active eruption (AAE), in patients with altered passive eruption (APE).
Methods: Eighteen CBCT scans were selected and 10 periodontal measurements were taken for each anterosuperior tooth compiling linear measurements and soft and bone tissue thicknesses.
Results: The data was organized in tables comparing the measurements for each dental group. The statistical analysis presented a relevant difference in the distance between the gingival margin and the cement-enamel junction for central and lateral incisors, indicating that these dental groups, when AAE is present, are more likely to have relatively smaller clinical crowns. The analysis also indicated that lateral incisors with AAE are more likely to have a thinner soft tissue volume.
Conclusion: It was possible to conclude that, by means of CBCT carried out in patients with APE, there is no difference in bone biotype as per the presence/lack of AAE in the teeth groups assessed. In the presence of AAE, incisors teeth have clinical crowns proportionally smaller and the lateral incisors presents a thinner gingival tissue volume.
