Resumo
Objective: To determine the linear measurements of human permanent dentition de-
velopment stages using Cone-Beam Computed Tomography. Methods: This study was
based on databases of private radiology clinics involving 18 patients (13 male and 5 fe-
male, with age ranging from 3 to 20 years). Cone-Beam Computed Tomography (CBCT)
images were acquired with i-CAT system and measured with a specific function of the
i-CAT software. Two hundred and thirty-eight teeth were analyzed in different develop-
ment stages in the coronal and sagittal planes. The method was based on delimitation
and measurement of the distance between anatomical landmarks corresponding to the
development of the dental crowns and roots. These measurements allowed the develop-
ment of a quantitative model to evaluate the initial and final development stages for
all dental groups. Results and Conclusions: The measurements acquired from different
dental groups are in agreement with estimates of investigations previously published.
CBCT images of different development stages may contribute to diagnosis, planning
and outcome of treatment in various dental specialties. The dimensions of dental crowns
and roots may have important clinical and research applications, constituting a noninva-
sive technique which contributes to in vivo studies. However, further studies are recom-
mended to minimize methodological variables.
