Summary
Reciprocating endodontic file systems show good acceptance among new users in undergraduate dental education. Concerns about work safety decrease with training, indicating these systems are safe and effective for teaching root canal shaping.
Area of Science:
- Endodontics
- Dental Education
- Materials Science
Background:
- Reciprocating endodontic one-file systems offer an alternative to traditional rotating systems for root canal shaping.
- Limited data exists on the subjective assessment and application quality of these newer systems, particularly in educational settings.
Purpose of the Study:
- To evaluate the subjective assessment and application quality of a reciprocating one-file system in undergraduate endodontic education.
- To gauge student acceptance and perceived work safety during the learning process.
Main Methods:
- A questionnaire-based study involving 42 undergraduate dental students with no prior experience with reciprocating file systems.
- Anonymously collected data using a numerical rating scale at four time points (t1-t4) throughout theoretical and practical training.
- Statistical analysis included a least significant difference post-hoc test with Bonferroni correction (p < 0.004).
Main Results:
- All rating scores improved after initial theoretical instruction.
- Significant improvements were observed in "time efficiency" (p = 0.002), "handling" (p < 0.001), and "overall impression" (p < 0.001) after practical training.
- The "overall impression" remained stable after the first practical training session.
Conclusions:
- Reciprocating endodontic systems demonstrate positive acceptance among novice users in undergraduate education.
- Concerns regarding "work safety" diminish progressively throughout the educational process.
- Reciprocating one-file systems are a safe and well-accepted modality for teaching root canal shaping to dental undergraduates.
