Summary
Resin infiltration effectively treats early cavities, with deeper lesions showing better resin penetration. This study confirms artificial caries models are suitable for resin infiltration research.
Area of Science:
- Dental research
- Cariology
- Materials science
Background:
- Resin infiltration is a modern approach to treating initial enamel caries.
- Limitations exist, necessitating further research to optimize resin infiltration techniques.
Purpose of the Study:
- To investigate resin infiltration into experimental caries-like lesions of varying depths.
- To assess the suitability of artificial caries models for resin infiltration studies.
Main Methods:
- Human molars and premolars were demineralized for 3, 6, 9, and 12 days to create caries-like lesions.
- Teeth were infiltrated with resin after incubation with sodium fluorescein.
- Resin penetration was quantified using fluorescence microscopy and EDS element analysis on serial sections.
Main Results:
- Lesion depth and expansion increased with longer demineralization times.
- Resin infiltration was consistently nearly complete across all tested lesion depths.
- Artificial caries-like lesions demonstrated suitability for experimental resin infiltration studies.
Conclusions:
- The study validates the use of artificial standardized caries-like lesions for evaluating resin infiltration efficacy.
- Findings support resin infiltration as a viable method for early caries management.
