Aim: This research used two distinct pediatric rotary files and traditional manual files for evaluation and contrast of the amount of apically extruded debris during root canal cleaning in deciduous teeth.
Materials And Methods: Thirty maxillary deciduous central incisors that showed no symptoms of resorption were removed and enrolled in the study. Three distinct file systems were used in the preparation of the canals: Group 1: Manual K-files (Uniflex NiTi K-Files), Group 2: Kedo SG Blue files (Kedo Dental, Chennai, India), and Group 3: Pro AF baby gold files (Kids-e-Dental, India). Apical extrusion was gathered and desiccated in Eppendorf tubes that had been previously weighed. The weight measured preoperative was deducted from the postoperative weight to get the dry weight. To examine the data's statistics, we applied a one-way ANOVA with Tukey's test.
Results: Rotary file systems produced considerably a lesser debris extrusion than the hand files ( < 0.05).
Conclusion: Debris was apically ejected from primary teeth by all the groups. The extrusion of debris apically was reduced while using Pro AF baby gold files.

The success rate of root canal treatment is high, but it can fail. In these cases, orthograde root canal retreatment is often the treatment of choice, for which numerous biomaterials are available on the market, including endodontic files. This systematic review aimed to study the endodontic files available on the market and establish their efficacy in root canal retreatment.

Background: TruNatomy instruments promises a more conservative alternative to conventionally used instruments. They are claimed by the manufacture to decrease the amount of debris extrusion as well as the torque generated during instrumentation, potentially resulting in lower post-operative discomfort and a safer more convenient experience for the patient and clinician.
Aim: To compare the effect of canal shaping using TruNatomy (TN) rotary system to RaCe (RC) rotary system on post-operative pain in necrotic maxillary bi-rooted premolars, while simultaneously inspecting the real-time dynamic forces produced during instrumentation.

This study compared the shaping ability and apical debris extrusion of four nickel-titanium (Ni-Ti) single-file systems in simulated curved root canals. Forty simulated curved root canals in resin blocks were randomly assigned to four groups ( = 10): Reciproc Blue (RCB), V-Blue, One Plex, and S-ONE. Images of the simulated root canals were captured before and after instrumentation.

Background: The formation of apical debris is a common occurrence during root canal preparation, which may cause postoperative complications like pain and infection. Different file motions-rotary, reciprocating, and adaptive-can influence the extent of debris extrusion.
Materials And Methods: A total of 90 extracted single-rooted teeth were randomly divided into three groups ( = 30) based on the file motion used: Group 1-rotary, Group 2-reciprocating, and Group 3-adaptive motion.

Background: After root canal preparation, apical debris may cause discomfort and delayed healing. Rotary, reciprocating, and adaptive file movements affect debris extrusion.
Materials And Methods: Sixty extracted mandibular premolars with single root canals were randomly divided into three file motion groups (n = 20): Group A (rotary motion using ProTaper Universal files), Group B (reciprocating motion using WaveOne files), and Group C (adaptive motion using TF Adaptive files).
