Abstract: This study evaluate the amount of debris and irrigants extruded apically during the use of different irrigation needle (open end & double side vented needle) attached to different device (pressurized water device  Aqua-pick 300 & syringe) with depth of penetration 2mm and 4mm from the working length. A Total number of 80 permanent single rooted teeth (premolars) with same working length were divided into two main groups, group A: penetration depth of irrigation syringe to 2mm from the working, group B: penetration depth of irrigation syringe to 4mm from the working length. Each group was subdivided into 4 subgroups (n=10) weight of extruded debris and irrigants were weighed and the data statistically analyzed by ANOVA and the Tukey test. Statistical analysis using one way ANOVA and Tukey test revealed that there was a high significant difference among the tested groups with least amount of apically extruded irrigants when the penetration length was 4mm from the working length with Aquapick device with double side vented needle. The study concluded that different irrigation needles attached to pressurized water(Aqua-pick 300 device)   with different penetration depth lead to less amount of apical extrusion of irrigants when compared to syringe with statistically non-significant differences.
