ABSTRACT

Objective:

The current study aimed at assessing the induced apical pressure at various simulated irrigant flow rates. Materials and

Methods:

Forty eight freshly extracted single-rooted premolars were decoronated and prepared to size 30 0.04 taper using HY-Flex CM rotary file system and were scanned using cone-beam computed tomography (CBCT). The scanned images were reconstructed to three-dimensional Computer-aided design models (CAD) and the 3D needle was also reconstructed. Finally, simulations were done by placing the 30 gauge open-ended needle 3 mm short of the working length.

Results:

There was a statistically significant difference (p<0.05) among the different groups compared. 1 ml/min flow rate induced the least apical pressures (p<0.05) as compared to the other types.

Conclusion:

1 ml/min flow rates induced the least apical pressures when open-ended needles are used for irrigation.(AU)
RESUMO

Objetivo:

O presente estudo teve como objetivo avaliar a indução de pressão apical em várias taxas de fluxo irrigante simuladas. Material e

Métodos:

Quarenta e oito raízes de pré-molares unirradiculares recém extraídos tiveram suas coroas removidas, foram preparados para uma conicidade de tamanho 30 0.04 através de um sistema rotatório de limas HYFlex CM e foram escaneados via tomografia computadorizada cone-beam (CBCT). As imagens escaneadas e as agulhas para irrigação foram reconstruídas em modelos tridimensionais de design assistido por computador (CAD). Ao final, foram feitas simulações através de agulhas de calibre 30 e 3 mm a menos que o comprimento de trabalho.

Resultados:

Houve diferença estatisticamente significativa (p<0.05) entre os diferentes grupos. A taxa de fluxo de 1 ml/min induziu as menores pressões apicais (p<0.05) quando comparada às demais taxas.

Conclusão:

Taxas de fluxo de 1 ml/min induziram as menores pressões apicais quando agulhas de ponta aberta foram utilizadas para irrigação (AU)
