This lesson will briefly cover the considerations required when using Fluoride in paediatrics.

Caries Prevention and Advice: 

See preventative pathway flowchart In 'Paediatric Pathways' 


Fluoride 

Fluoride overdose in a child: 

  • The following shows the concentration of fluoride in water supply, in order of increased risk of mottling (1). 
    • <0.9 ppm 
    •  0.9 ppm 
    • 2 ppm 
    • 2+ ppm 
  • Safe dose =  1mg/kg body weight. 
  • Unsafe dosage which can be lethal =  5mg/kg body weight 
    • Requires hospital admission.  
    • If <5mg/kg - given milk 
    • If 5mg+/kg - gastric levage 
  • Lethal dose = 32-64mg/kg body weight. 
  • Primarily, we aim to provide a safe amount of fluoride without causing fluorosis or systemic effects.

Doses: 

  • Toothpaste: 1000ppm F = 1mgF/ml 
  • Toothpaste: 1500ppm F = 1.5mg F/ml 
  • Daily fluoride mouth rinse  0.05% NaF = 0.023% F = 0.23mg F/ml (note weekly mouthrinse = 0.2% NaF) 
  • Fluoride varnish 22,600ppm  5% NaF = 2.26% F = 22.6mg/ml 
  • High Fluoride toothpastes: 
    • 2800ppm = 0.619% NaF 
    • 5000ppm = 1.1% NaF  (2)

Other Advancing Treatments: 

ICON

  • This is a clear resin composite or resin infiltrate.  
    •  ICON is recommended to treat carious white spot lesions reaching up to the outer third of dentine. 
    • Consists of 15% HCl acid, ICON dry (99% ethanol) and ICON infiltrate (methacrylate-based resin) (3)

SDF

  • SDF = silver diamine fluoride 
    • Contains ionic silver, fluoride and ammonium. 
  • Alternative to fluoride varnish – used as a preventative measure.  
  • Can be used to arrest early carious lesions and help treat dentine hypersensitivity.  
  • Is thought to make a fluoride reservoir within tooth structure and help promote remineralisation.  
  • Disadvantage: may cause staining of lesion.  

CPP-ACP

  • CPP-ACP is more commonly known as 'Tooth mousse'. It is a calcium phosphate topical cream.
  • Therefore, it does not contain fluoride- so some patients may prefer this.
  • It not available on prescription in the UK and can be expensive.
  • Can be used at home - applied daily with finger post brushing. 
  • There is some evidence for the use of CPP-ACP.
    • Some evidence that is good for use in orthodontics for treatment of white spot lesions.
    • It anecdotally reduces sensitivity also and supposedly increases mineralisation.

Conclusion

You should now be aware of the appropriate doses of Fluoride given in children. Applying these to your preventative pathways will allow you to confidently provide accurate, appropriate and safe preventative advice.
