Resumo: Purpose: The aim of this study was to compare the apical extrusion of debris during rotary versus ultrasonic instrumentation of root canals. Methods: The sample comprised 20 mandibular premolars with similar root length. To collect the extruded material during endodontic instrumentation, acrylic resin containers were fixed on the root external surfaces. All teeth were prepared with Gates-Glidden drills at the cervical and middle thirds of the root canal. Root canal instrumentation was accomplished using ultrasound or rotary systems (n=10/group) according to the established work length. The resin containers were weighed before and after instrumentation, and the weight difference was considered the amount of extruded material. Data were analyzed by Mann-Whitney test at a 0.05 level of significance. Results: Both instrumentation techniques showed large variability of amount of extruded material with values ranging from 0.0009 to 0.0860 g. No significant difference was found between the two experimental groups (P>0.05). Conclusion: It can be concluded that ultrasonic or rotary systems promoted similar apical extrusion of debris during root canal instrumentation. Key words: Root canal preparation; tooth apex; waste products

Metodologia: A amostra constituiu-se de 20 pré-molares inferiores com dimensões radiculares similares. Para coleta do material extruído apicalmente durante a instrumentação endodôntica, foram fixados recipientes de resina acrílica na superfície externa das raízes. Todos os dentes tiveram os terços cervical e médio dos canais radiculares preparado com brocas Gates-Glidden. Após odontometria, a instrumentação apical foi realizada com sistema ultra-sônico ou sistema rotatório (n=10/grupo). Os recipientes de resina foram pesados antes e após a instrumentação e a diferença de peso foi considerada a quantidade de material extruído. Os dados foram analisados por teste de Mann-Whitney, ao nível de significância de 0,05. Resultados: Houve grande variabilidade de quantidade de material extruído para ambas as técnicas de instrumentação, com valores de 0,0009 a 0,0860 g. Não houve diferença estatisticamente significante entre os dois grupos (P>0.05). Conclusão: Pode-se concluir que ambas as técnicas de instrumentação testadas, com ultra-som ou sistema rotatório, apresentaram extrusão apical de debris em quantidade semelhante.
