Brief Summary

This prospective cohort study evaluates dental students' self-assessment of clinical endodontic performance and compares it with independent evaluations conducted in a dental education clinical setting. Endodontic treatments are performed by undergraduate dental students using two distinct rotary file systems selected according to routine clinical practice. Students' self-assessments are prospectively collected using a structured questionnaire and compared with evaluations performed by two experienced evaluators with access to clinical and radiographic information, considered the reference standard, as well as by two different experienced evaluators using radiographic information only. Secondary analyses examine whether assessment outcomes differ according to the rotary file system used. The null hypothesis is that there is no difference between dental students' self-assessments and reference standard evaluations of endodontic treatment quality, and that assessment outcomes do not differ according to the rotary file system used.

Outcome Measures

Primary Outcomes (1)

  • Agreement between dental students' self-assessment and reference standard evaluation of endodontic treatment quality

    The level of agreement between dental students' self-assessment of completed endodontic treatments and evaluations performed by two experienced evaluators with access to both clinical and radiographic information, considered the reference standard.

    Up to 2 weeks (at completion of endodontic treatment)

Secondary Outcomes (4)

  • Agreement between radiographic-only evaluation and reference standard evaluation of endodontic treatment quality

    Up to 2 weeks (at completion of endodontic treatment)

  • Proportion of self-reported assessment findings by rotary file system based on dental students' self-assessment

    Up to 2 weeks (at completion of endodontic treatment)

  • Proportion of reference standard evaluation findings by rotary file system

    Up to 2 weeks (at completion of endodontic treatment)

  • Proportion of radiographic-only evaluation findings by rotary file system

    Up to 2 weeks (at completion of endodontic treatment)
