Summary
This study quantified remaining orthodontic bracket adhesive on teeth using 3D scans. Resin-modified glass ionomer adhesives left less residue than resin-based types, impacting enamel surface analysis.
Area of Science:
- Orthodontics
- Dental Materials Science
Background:
- Assessing residual adhesive after orthodontic bracket debonding is crucial for enamel evaluation.
- Previous methods lacked precise 3D quantification of remaining adhesive.
- Understanding adhesive behavior aids in selecting optimal bonding agents.
Purpose of the Study:
- To quantitatively determine the 3D amount of adhesive remaining on teeth post-orthodontic bracket debonding.
- To compare adhesive remnant amounts among different adhesive types.
- To correlate quantitative adhesive parameters with the Adhesive Remnant Index (ARI).
Main Methods:
- Investigated three adhesive types on 45 extracted premolars.
- Utilized 3D scanning of tooth surfaces before and after debonding.
- Measured remaining adhesive volume, maximum height, mean maximum height, mean height, and ARI scores.
Main Results:
- Significant differences in remaining adhesive volume and mean height were observed between adhesive types (P <0.05).
- Resin-modified glass ionomer adhesives resulted in less remaining adhesive compared to resin-based adhesives.
- Significant correlations were found between quantitative adhesive parameters and ARI scores (r = 0.332-0.486; P <0.05).
Conclusions:
- 3D quantitative analysis provides detailed insights into the debonded enamel surface.
- Adhesive type significantly influences the amount of residual adhesive.
- ARI scores correlate with quantitative measurements, aiding in clinical assessment.
