NCT01674933

Brief Summary

The study will compare the effectiveness of Duraphat® fluoride varnish in preventing any further dental decay among 3-4 year old children in nursery schools. It is important to ascertain the additional preventive value that fluoride varnish may provide when applied in conjunction with other preventive measures which form part of a national dental health improvement programme targeting children at risk from dental decay. 1600 children will be recruited into the study for 2 years.

Eligibility Criteria

Age36 Months - 50 Months
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Children attending nurseries which cover significant numbers of children whose home postcode is within the most deprived quintile of postcodes as measured by the Scottish Index of Multiple Deprivation (SIMD) (Scottish Government 2011).
  • Children in the first year of nursery school (known as the 'ante pre school year'). On average the children will be three years old.
  • Every eligible child in participating nurseries will be invited to join the study, irrespective of the SIMD ranking of their own postcode.
  • Children with or without pre-existing cavities, as the cavity can be treated through the usual primary care dental service (i.e. as part of 'treatment as usual').

You may not qualify if:

  • Children with contraindications for the Duraphat® varnish i.e. hypersensitivity to colophony and/or any other constituents, ulcerative gingivitis, stomatitis, bronchial asthma, history of allergic episodes requiring hospital admission (e.g. asthma).
  • Receipt of fluoride supplements due to a small risk of fluorosis.
  • Abnormalities of the skin around the mouth, lips (e.g. cold sores) and soft tissue lesions.
