Introdução: A correta determinação do comprimento de trabalho para o
tratamento endodôntico de dentes decíduos é um desafio para o médico dentista
devido às diferenças morfológicas e anatómicas, a exfoliação fisiológica e a
frequente falta de colaboração dos pacientes. Os localizadores apicais
eletrónicos têm vindo a ser cada vez mais utilizados em dentes decíduos para
este efeito. O objetivo deste trabalho foi testar e comparar métodos de
determinação do comprimento do canal radicular, sendo um deles o método
radiográfico, e os outros dois, localizadores apicais eletrónicos diferentes, em
modelos de dentes decíduos artificiais.
Materiais e Métodos: Foram utilizados neste estudo seis dentes
decíduos artificiais anteriores (incisivos) e seis posteriores (segundos molares).
Após se ter realizados as cavidades de acesso em cada um dos dentes, os
comprimentos dos seus canais radiculares foram determinados através do
método radiográfico e com os localizadores apicais eletrónicos Root ZX e
ProppexL
e comparados com as suas medidas reais.
Resultados: Foi observado que as medições realizadas com o método
radiográfico apresentavam uma diferença estatística significativa, quando
comparados com o tamanho real dos canais radiculares, ao contrário das
medições realizadas com os aparelhos que localização apical eletrónica, que
apresentarem-semais fiéis ao comprimento real de trabalho.
Conclusão: Os métodos de determinação do comprimento dos canais
radiculares com localizador apical eletrónico foram os que demonstraram
melhores resultados, provando a viabilidade destes dentes para o estudo e
pesquisa em Endodontia e Odontopediatria.
Introduction: The correct determination of the working length for the endodontic treatment of primary teeth is a challenge for the dentist due to the morphological and anatomical differences, physiological exfoliation, and the frequent lack of patient cooperation. Electronic apical locators have been increasingly used in primary teeth for this purpose. The aim of this study was to evaluate and compare methods for determining the length of the root canal, one of them being the radiographic method, and the other two, different electronic apex locators, in models of artificial deciduous teeth. Materials and Methods: Six artificial deciduous anterior teeth (incisors) and six posterior (second molars) were used in this study. Access cavities were made in each one of the teeth and the lengths of their root canals were determined using the radiographic method and two different electronic apex locators, the Root ZX and ProppexL and compared with their actual measurements. Results: It was observed that the measurements obtained with the radiographic method showed a statistically significant difference when compared to the actual size of the root canals, unlike the measurements performed with electronic apex locators, which are more effective when compared to the actual length. Conclusion: The electronic apex locators showed the best performance in determining root canal length in comparison with the radiographic method, proving the viability of these teeth for study and research in Endodontics and Pediatric Dentistry.
