The smear layer (SL) on dentin can enhance fluoride uptake at lower concentrations but its effect diminishes with higher fluoride levels. Surface treatments also impact how much fluoride dentin absorbs.

Area of Science:

  • Dental materials science
  • Biomaterials
  • Surface chemistry

Background:

  • Polishing dentin creates a smear layer (SL) that may affect fluoride absorption.
  • Understanding fluoride uptake is crucial for dental caries prevention.

Purpose of the Study:

  • To investigate the impact of the smear layer on fluoride uptake in dentin.
  • To evaluate how different smear layer removal methods influence fluoride absorption.
  • To determine if fluoride concentration affects the smear layer's influence on uptake.

Main Methods:

  • Bovine dentin samples were prepared with and without a smear layer.
  • Smear layers were removed using tannic acid, EDTA, phosphoric acid, or air polishing.
  • Samples were fluoridated with either 1200 ppm or 12000 ppm fluoride solution.

  • Fluoride uptake was quantified using KOH-soluble and structurally bound fluoride measurements.

    • Main Results:

    • Scanning electron microscopy showed varying smear layer removal effectiveness, from partial removal to collagen exposure.
    • The smear layer increased fluoride uptake at 1200 ppm but not at 12000 ppm.
    • Phosphoric acid treatment, which exposed collagen, showed different fluoride uptake patterns.

    Conclusions:

    • The presence of the smear layer and surface treatment significantly influence fluoride uptake in dentin.
    • The effect of the smear layer on fluoride uptake is dependent on the applied fluoride concentration.
