Summary
Three root canal file systems showed similar fracture resistance in mandibular premolars. XP-endo® shaper demonstrated slightly better results, though not statistically significant, compared to Reciproc® and Self-adjusting file (SAF).
Area of Science:
- Endodontics
- Dental Materials Science
- Biomaterials
Background:
- Root canal therapy is crucial for saving teeth but requires balancing cleaning efficacy with preserving tooth structure.
- Innovative endodontic file systems aim to improve cleaning while minimizing risks to tooth integrity.
- Evaluating the impact of new instrumentation techniques on root fracture resistance is essential for clinical success.
Purpose of the Study:
- To compare the effect of three novel file systems—XP-endo® shaper, Reciproc®, and Self-adjusting file (SAF)—on the fracture resistance of mandibular premolars.
- To determine if differences in instrumentation technique influence the mechanical strength of endodontically treated teeth.
- To provide data guiding the selection of file systems that optimize root canal treatment outcomes.
Main Methods:
- Thirty single-rooted mandibular premolars were prepared and divided into three groups (n=10) for instrumentation with XP-endo® shaper, Reciproc®, or SAF.
- Roots were decoronated, mounted in resin, and subjected to fracture resistance testing using a universal testing machine.
- Statistical analysis involved one-way ANOVA and Bonferroni post hoc tests to compare fracture resistance between groups.
Main Results:
- No statistically significant difference in fracture resistance was found among the three tested file systems (p>0.05).
- XP-endo® shaper exhibited a trend towards higher fracture resistance compared to Reciproc® and SAF.
- The instrumentation methods evaluated did not compromise the overall fracture resistance of the mandibular premolars tested.
Conclusions:
- XP-endo® shaper, Reciproc®, and SAF demonstrate comparable outcomes regarding the fracture resistance of mandibular premolars.
- While not statistically significant, XP-endo® shaper showed a potential advantage in maintaining tooth strength post-instrumentation.
- All three file systems appear to be safe alternatives for root canal instrumentation concerning tooth fracture resistance.
