First Nations Regional Longitudinal Health Survey
(2002/03)
• Directed & implemented by First Nations following principles of Ownership, Control, Access & Possession
• 238 communities; self-reports
• Provided information for planning, policy & advocacy
• Parents asked about child’s (n=6,657) experience of Baby Bottle Tooth Decay–– 30%30% of 3-5 year old children affected

Healthy Smile Happy ChildHealthy Smile Happy Child• Goal: to reduce incidence/severity of ECC
•• Community developmentCommunity development principles to promote preschool oral health and prevent ECC
• Project staff built relationships with existing existing programsprograms to enable community action

• Follow-up (n=319); baseline (n=408)• Significant improvements in parental knowledge,
attitudes, and behaviors• Reduced dt score: mn(SD)
• 2.1 (3.4) follow-up vs. 1.6 (2.7) baseline, p=.017• Reduced age adjusted deft rate: mn(SD)
• 4.2 (5.0) follow-up vs. 3.9 (5.0) baseline, p<.001• Age adjusted logistic regression for S-ECC

A 2-year community-randomized controlled trial of fluoride varnish to prevent early childhood caries in Aboriginal childrenLawrence HP et al. Community Dent Oral Epidemiol 2008
CIHR Grant MOP #64215
Objective: to measure effectiveness of FV and caregiver counseling in preventing in ECC in Aboriginal children
Study design: cluster randomized trial control: caregiver counselingtest: caregiver counseling plus FVplus FV
Sample size: n=1275 (6 mos.- 5 yrs.) Treatment effect (primary outcomes):
– net reduction in caries increment = 18%• measured at d1 and d3 level
–– NNT = 26NNT = 26 to prevent one child from developing caries
Treatment effect: Secondary outcomes
• GA tx: “the proportion of children who had GA dental care 25% lower in test group1”
• not yet reported:– oral health quality of life– cost– acceptability by parents
