Summary
Chitosan-based endo-radiopaque solution (CERS) significantly improves visualization of root canal anatomy in human teeth. This study compared CERS with traditional contrast media for enhanced endodontic imaging.
Area of Science:
- Endodontics
- Dental Radiology
- Biomaterials
Background:
- Accurate visualization of root canal anatomy is crucial for successful endodontic treatment.
- Traditional contrast media have limitations in depicting complex root canal systems.
Purpose of the Study:
- To evaluate the efficacy of ionic and non-ionic contrast media for in vitro root canal visualization.
- To assess the in vivo performance of chitosan-based endo-radiopaque solution (CERS) for root canal anatomy imaging.
Main Methods:
- In vitro study: 120 teeth analyzed with 4 contrast media and sodium hypochlorite.
- In vivo study: 80 teeth compared Xenetix 350 + NaOCl with CERS using radiovisiography.
- Statistical analysis included Kruskal-Wallis and Mann-Whitney U tests.
Main Results:
- Xenetix 350 + 5.25% NaOCl showed significantly higher visualization in vitro.
- CERS demonstrated a statistically significant depth of ingress in vivo.
- CERS was effective in identifying aberrant root canal anatomy.
Conclusions:
- Chitosan-based endo-radiopaque solution (CERS) provides superior visualization of human premolar and molar root canal anatomy.
- CERS shows promise as an advanced imaging agent in endodontics.
