Summary
Monocalcium phosphate monohydrate (MCPM) gel enhances fluoride (F) uptake in human tooth root surfaces. This dental treatment significantly increases F absorption, offering a promising clinical application for improved dental health.
Area of Science:
- Dental science
- Biomaterials science
Background:
- Monocalcium phosphate monohydrate (MCPM) gel application increases enamel reactivity with fluoride (F).
- Previous research demonstrated MCPM gel's effect on enamel, but its impact on root surfaces was unknown.
Purpose of the Study:
- To investigate the efficacy of MCPM gel in enhancing fluoride uptake by human tooth root surfaces.
- To determine if MCPM gel treatment improves fluoride retention in root dentin.
Main Methods:
- Human teeth samples were treated daily with MCPM gel for 10 minutes.
- Following MCPM gel application, samples were immersed in a 1-ppm fluoride solution for 5 days.
- Fluoride uptake was quantified and compared between treated and control groups.
Main Results:
- MCPM gel treated samples showed significantly greater fluoride (F) acquisition compared to controls.
- The incorporated fluoride is primarily apatitic, not calcium fluoride (CaF2), due to the undersaturated fluoride solution.
- The experimental treatment demonstrated a significant increase in F uptake in root surfaces.
Conclusions:
- MCPM gel treatment is effective in enhancing fluoride uptake by human root surfaces.
- The short treatment duration and ease of application suggest clinical feasibility.
- This method shows potential for improving root caries resistance and remineralization.
