Resumo

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.
