ABSTRACT

Objective:

To evaluate the efficacy of rotary Kedo-S and hand K-files in shaping ability in primary canines using cone beam computed tomography. Material and

Methods:

Thirty extracted primary maxillary and mandibular canines were selected. Using cone beam computed tomography the teeth were scanned before instrumentation. In Group I, the teeth were prepared using stainless steel K file up to the size of 40. In the Group II teeth, U1 size Kedo-S rotary file was used in crown down technique. The instrumented teeth were scanned again with cone beam computed tomography and the images were compared.

Results:

The canal taper was more conical for rotary Kedo-S files as compared to K-files, which was statistically significant.

Conclusion:

Canal preparation with Rotary files resulted in more conical canals when compared to manual instrumentation in primary teeth that contributes to more uniform obturation. (AU)
RESUMO

Objetivo:

Avaliar a eficácia da instrumentação rotatória com limas Kedo-S e instrumentação manual com limas Kerr na modelagem de caninos decíduos utilizando tomografia computadorizada de feixe cônico (TCFC). Material e

Métodos:

Foram selecionados 30 caninos decíduos superiores e inferiores extraídos. Usando a TCFC, os dentes foram escaneados previamente a instrumentação. No Grupo I, os dentes foram confeccionados com limas de aço inoxidável até o tamanho 40. Nos dentes do Grupo II, utilizou-se a lima rotatória Kedo-S tamanho U1 na técnica coroaápice. Os dentes instrumentados foram novamente escaneados por TCFC e as imagens foram comparadas.

Resultados:

A conicidade do canal foi maior no grupo com instrumentação rotatória em comparação com a instrumentação manual, com diferença estatística significante entre eles.

Conclusão:

O preparo do canal com o Rotary resulta em canais mais cônicos em comparação com a instrumentação manual em dentes decíduos, o que contribui para uma obturação mais uniforme.(AU)
