Evaluation and comparison of mandibular molar root canal filling quality performed by undergraduate preclinical dental students.

ABSTRACT: The present study aims to evaluate the quality of root canal fillings (RCFs) on extracted mandibular molars performed by undergraduate students during their preclinical training which spans 2 academic years. Endodontics records and periapical radiographs of 260 extracted human first and second mandibular molars without site specification consisted the sample of this retrospective cross-sectional study. All root canal fillings were performed by undergraduate students during the preclinical phase of their training The samples collected were assessed using radiographs based on three quality criteria: length, density, and taper. Chi-square test was used for statistical analysis and Cohen's Kappa coefficient was implemented to assess inter-rater reliability. The majority of the evaluated RCFs w
