| Resumo: | Cephalometric analysis is the mensuration of linear and angular measures through
demarcation points as distances and lines on teleradiography, and is considered of
fundamental importance for diagnosis and orthodontic planning. In this manner, the objective
of this research was to compare cephalometric measurements obtained by dentists and
radiologists from the analysis of the same radiograph, in a computerized cephalometric
analysis program. All research participants marked 18 cephalometric points on a 14-inch
notebook computer, as directed by the program itself (Radiocef 2®). From there, they
generated 14 cephalometric parameters including skeletal, dental-skeletal, dental and soft
tissue. In order to verify the intra-examiner agreement, 10 professionals from each group
repeated the marking of the points with a minimum interval of eight days between the two
markings. The intra-group variability was calculated based on the coefficients of variation
(CV). The comparison between groups was performed using the Student t-test for normally
distributed variables, and using the Mann-Whitney test for those with non-normal distribution.
In the group of orthodontists, the measurements of Pog and 1-NB, SL, S-Ls Line, S-Li Line
and 1.NB showed high internal variability. In the group of radiologists, the same occurred
with the values of Pog and 1-NB, S-Ls Line, S-Li Line and 1.NA. In the comparison between
groups, all the analyzed linear values and two angular values showed statistically significant
differences between radiologists and dentists (p <0.05). According to the results, the
interexaminer error in cephalometric analysis requires more attention, but does not come from
a specific class of specialists, being either dentists or radiologists. |
