EFICÁCIA DA INTERVENÇÃO EDUCACIONAL À DISTÂNCIA NA CAPACITAÇÃO DE CIRURGIÕES-DENTISTAS DA REDE PÚBLICA SOBRE O USO CONSCIENTE DA TOMOGRAFIA COMPUTADORIZADA DE FEIXE CÔNICO: UM ENSAIO CLÍNICO CONTROLADO QUASE-EXPERIMENTAL

Abstract

Objective: To verify the effectiveness of an educational intervention by videoconference, for dentists of a public health service, on acquiring knowledge in cone-beam computed
tomography. Materials and Methods: This is a controlled clinical trial with structured questionnaires on the judicious use of cone-beam computed tomography, before and after the educational intervention. Study participants were divided into control (faceto-face class) and experimental (videoconference class) groups. A total of 133 dentists participated in the pre-test (questionnaire applied before the intervention) and 129 in the post-test (questionnaire applied after the intervention). The analyzes were performed to evaluate the variables of the teaching methodology and to compare the proportion of correct and “I do not know” answers between times, broken down by the dental specialty of the participants. The level of significance adopted was 0.05. The chi-square tests and the binary logistic regression model were used and, when significant, the Bonferroni
post-hoc test was applied. Results: The analysis of the answers “I don’t know” and correct answers between the teaching modalities showed no significant change in the results.
The result of the “I don’t know” answers showed a significant difference between the times, where the percentage of these answers, after the intervention, varied from 23.6% to 4.7% (p<0.001). In all specialties, this reduction was significant in questions related to knowledge about radioprotection. The increase incorrect answers were almost 10% (p<0.001). Conclusion: Professional training through the videoconference method
proved effective and comparable to the face-to-face method for acquiring knowledge in cone-beam computed tomography.
