Abstract
Introduction
The purpose of this study was to observe and evaluate 3-dimensional pulp cavity changes
during orthodontic treatment.
Methods
Eighty-seven patients formed the study sample and were divided into an experimental
group (48 patients) and a control group (39 patients). Cone-beam computed tomographic
(CBCT) records were obtained before the start of the treatment (T0) and after space
closure for the experimental group, whereas for the control group CBCT images were
obtained approximately 17–18 months (T1) after obtaining the first image (T0). CBCT
data were reconstructed with surface and volume rendering software (Mimics; Materialise,
Leuven, Belgium), and the volumetric images were modified to display the teeth from
various orientations. Six anterior teeth were segmented and their pulps isolated.
Paired t test was used to check for statistical significance.
Results
The difference in the pulp volume was statistically significant at P < .05 for all the anterior teeth in the experimental group and at P < .05 for the right canine, P < .05 for the right and left lateral incisors, and P < .05 for the left central in the control group.
Conclusions
Orthodontic treatment in the experimental group produced a significant decrease in
the size of the pulp, which was statistically significant.
