Aim and objective The present study aims to evaluate the difference in torsional resistance of two reciprocating nickel-titanium (Ni-Ti) rotary files: WaveOne Gold EdgeOne Fire. Materials methods A total 40 instruments (n = 40): 20 Small (WOGS) Fire (EOFS) were divided into groups. Each instrument was tested using a device already validated previous studies compare resistance. static test imple...

Objective: The aim of this study was to evaluate the effect different glide path files on amount apically extruded debris. Material and Methods: Sixty single-canaled mandibular premolars were accessed randomly divided into three groups (n= 20) according file used for glid creation; group A using Traverse file, B WaveOne Gold Glider, C stainless steel K file. All teeth then instrumented Reciproc...

Abstract Background Radiographic analysis of tooth morphology is mandatory for accurate calibration the degree canal curvature angle and radiographic working length to its real dimensions in case difficulty assessment protocols. This study aimed determine impact root on maintaining original axis prepared canals using a reciprocating rotary instrumentation technique. Methods image was performed ...

AIM: The aim of the study was to evaluate and compare effects WaveOne Protaper Next on volume dentin removed, centering ability thickness using CBCT human mandibular molars. MATERIALS AND METHOD: Methodology: 50 recently extracted molars were taken divided into two groups i.e. Group 1- Pro taper next -2 Wave One. distal root discarded mesiobuccal canals selected. Further selected scanned standa...

Background: This study aimed to compare the continuous rotation and reciprocating movements of rotary files in achieving apical patency root canal retreatment. Materials Methods: vitro, experimental evaluated 64 extracted mandibular molars. The teeth were prepared up F3 with ProTaper Universal obturated using lateral compaction technique. divided into four groups (n = 16) based on mesiobuccal c...

Objective: The purpose of this study was to evaluate the effect using single-file with different tapered coronal flaring files on dentinal crack. Material and Methods: Human extracted mandibular premolars (n=128) were selected divided into four groups (n=32) based instruments; Group 1, One Flare; 2, Endoflare; 3, Gates Glidden Drills; 4, Control Group. Specimens subgroups single file system (n=...
