Özet

AIM: The aim of this study to compare the effect of apically extruded debris amount of various kinematic

(continuous rotation, reciprocation and adaptive motion) with conventional needle irrigation (CNI), passive

ultrasonic irrigation (PUI) and sonic irrigation (SI).

Methodology: 162 mandibular premolar teeth selected according to certain criteria were used in this study

(n:18). Continuous rotation (ProTaper Next, Dentsply, Ballaigues, Switzerland), reciprocation (OneRECI,

MicroMega, Besancon, France) and adaptive motion (TF Adaptive, SybronEndo, Orange, CA) were used for

root canal shaping procedures. CNI, PUI (DTE E97, Guilin Woodpecker Medical Instrument Co., Guilin,

Guangxi, China) and SI (EndoActivator, Dentsply Sirona, Baillagues, Switzerland) were used for final

irrigation procedures. 9 experimental groups were created to use three different root canal shaping

techniques in three different final irrigation methods. To ensure standardization in the study, root lengths (20

mm), apical preparation diameters (25/.06) of the root canals, irrigation amounts used and irrigation times

were adjusted to be the same. Root canal shaping and irrigation procedures were performed after the teeth

were placed in Eppendorf tubes. Two-way ANOVA and post hoc Tukey HSD tests were used for data

evaluation, with statistical significance set at p<0.05.

According to the results, in all kinematics, reciprocation resulted in the least statistically significant ADE. In all

final irrigation procedures CNI led to statistically significantly greater apical debris extrusion (ADE) than SI

and PUI. Shaping with continuous rotation and using CNI for final irrigation led to the highest amount of ADE

among all groups.

Results: • ADE is influenced by both the shaping and irrigation techniques employed.

• Despite the various shaping and irrigation systems used over the years, ADE has not been

prevented; however, reciprocation may be more advantageous in this regard compared to other kinematics
