ISRCTN24958829.

Trial name or title	Dental RECUR trial (Comparison of a new with standard child and family primary care service to reduce the re‐occurrence of childhood dental caries (Dental RECUR Trial))
Methods	Randomised controlled trial
Participants	Children aged 5 years to 7 years old who are having 1 or more teeth removed at a secondary care centre
Interventions	All participants are given help to find and register with a local family dentist if they wish. Every child is given a free dental checkup 2 years after the extraction. This is done at the child's school by a dentist trained in looking for dental decay in children. All families are invited to attend a review appointment at some point in the first 6 weeks following tooth extraction. The session will be delivered by a dental nurse. For families in the new service group, the session will look at ways to help prevent further decay in the child's remaining first teeth and permanent teeth. The new service group families are also invited for an appointment with their dentist every 3 months for a year. At the end of the year the child will go back to visiting their dentist as normal. For families in the usual follow‐up care group, the session will look at future dental development for their child. At the end of the session families in this group will go back to visiting their dentist as normal
Outcomes	Main outcome: dental caries experience after 2 years Other outcomes: 1. parental readiness to change and beliefs about caring for their children's teeth. Measured by the modified Contemplation Ladder 2. parental self‐efficacy in relation to the implementation of dental health‐related behaviours for the study children. Measured by the Child Oral Health Behaviours Questionnaire and Parenting Self‐Efficacy Scale 3. oral cleanliness by plaque assessment of anterior teeth at dental examinations 4. use of dental services; child oral health behaviours including dietary behaviours. Measured by the Child Oral Health Behaviours Questionnaire 5. NHS costs will be measured: from a public sector, multiagency perspective, they will: 5.1. fully cost the community‐based DR‐BNI and prevention in dental practice programme (as compared with costs of usual dental care) 5.2. record study participant dental service use, primary and secondary care health service use, social care and special educational service use (using a CSRI, costed using national unit costs) 5.3. conduct a primary cost‐effectiveness analysis (using dental caries rates as measure of effectiveness) 5.4. conduct a secondary cost‐consequences study relating costs to a range of consequences spanning measures of: dental decay in participating child, regular dental attendance, parent participation in better oral health behaviours (e.g. sugar‐free bedtime routine) and school attendance, and where appropriate, potential child neglect
