Dental Caries Clinical Trial
Official title:
Comparison Of The Caries-Protective Effect Of Fluoride Varnish (Duraphat®) With Treatment As Usual In Nursery School Attendees Receiving Preventive Oral Health Support Through The Childsmile Oral Health Improvement Programme: An RCT
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.
The objective of this study is to compare the effectiveness of Duraphat® fluoride varnish
plus treatment as usual (TAU) with TAU only in preventing any further dental decay.
Thus the study is a clinical trial of treatment as usual (TAU) versus TAU plus fluoride
varnish in the nursery school setting. TAU is the core Childsmile Nursery intervention
(supervised daily toothbrushing with fluoride toothpaste, free dental packs of fluoride
toothpaste, toothbrushes and advice).
Children will be screened by asking parents whether or not the child has previously been
hospitalised with asthma or diagnosed with any allergies. Provided that a child has no
contraindications to fluoride varnish then the child can proceed to study inclusion. On the
day of the planned application, the dental nurse will carry out a risk assessment to reduce
the possibility of children with oral/facial infections being included. After excluding
non-eligible children, a baseline dental examination will take place, followed by
randomisation into treatment as usual or treatment as usual plus fluoride varnish. This
second group will receive up to four fluoride varnish applications at 6 month intervals.
After two years, all study children will be offered a final dental examination.
