Question
In children from first tooth eruption to age five seen in primary care, does fluoride varnish applied at well visits, compared with no varnish or dental referral alone, reduce new caries?
Bottom Line
Yes. The USPSTF gives a grade B to varnish applied by primary care clinicians to every child's baby teeth once they erupt (US Preventive Services Task Force, 2021), and pooled trials show fewer decayed surfaces in primary teeth with varnish (Marinho et al., 2013).
The Evidence
USPSTF, 2021. Population: children younger than five years. Findings: two grade B recommendations, varnish from the first tooth and oral fluoride from six months where the home water is low in fluoride, and an I statement on caries screening by primary care clinicians. The Task Force supports the varnish and the supplement where needed, but it does not claim that primary care screening alone prevents caries, and the brief does not either.
AAP clinical report, 2020. Clark and colleagues, for the Section on Oral Health, recommend fluoride varnish in the primary care setting for all children from tooth eruption, applied every three to six months, alongside a dental home (Clark et al., 2020).
Cochrane review, 2013. Marinho and colleagues pooled randomized trials of fluoride varnish in children and adolescents. In primary teeth, varnish was associated with a reduction in decayed, missing and filled surfaces of about [37] percent, a finding the review rated as moderate-quality evidence (Marinho et al., 2013).
Limitations
Many trials in the Cochrane review were run in schools or dental settings rather than primary care, and some are older. The effect in primary care depends on applying varnish consistently at visits, which trials do not test. Certainty is moderate, not high.
Practical Considerations for the Site
1. Workflow: apply at every well visit from first tooth through age five, about every [three to six] months, after the examination; it takes about a minute.
2. Caregiver questions: varnish is safe; a small amount is swallowed; teeth may look yellow until brushed the next day; avoid hard or sticky foods for a few hours.
3. It supplements, not replaces, a dental home: continue referral at each visit.
4. Water fluoridation: some communities have changed their fluoridation policy, so each family's water status is confirmed rather than assumed, and supplements are considered where water is deficient.
5. Billing: varnish application is commonly covered for young children, including under Medicaid; confirm with the site's billing office.
Recommendation for the Preceptor
Adopt fluoride varnish at well visits for children from first tooth to age five, beginning with the next well-visit schedule, and track the proportion of eligible children receiving it.

How this NU581 Unit 8 example is structured
The answer comes before the evidence, since a preceptor asking a practical question may read only the top. Each source is then described in a consistent pattern: who issued or conducted it, when, in what population, with what finding and how much certainty. The USPSTF recommendation is presented with its grade and its companion statements, including an insufficient-evidence finding on routine caries screening by primary care clinicians, reported so no one overstates the case. The Cochrane review is described by its outcome, decayed surfaces prevented, with its certainty rating quoted rather than paraphrased. A limitations paragraph acknowledges that many trials were run outside primary care. The practical section is sized to the site: a workflow suggestion for the well visit and a line recognizing that community water fluoridation policy has changed in some places, so the local water status is confirmed rather than assumed.

NU581 Unit 8 questions, answered
Can the brief answer a question from my real site?
Yes, a question arising at your site is exactly what most prompts want, as long as the brief contains no identifying information about patients, staff or the site itself. The evidence and the answer are general; only the context is local. The sample uses a composite site with a composite dental access problem to show that framing.
How many sources does a two-page brief need?
Usually three to five strong ones rather than many weak ones. A current guideline or recommendation statement, a systematic review and one or two key trials often suffice. Check your rubric for a minimum and a recency window. The sample relies on three principal sources, each chosen because it answers part of the question directly.
Should the brief make a recommendation to the site?
Most prompts ask for one, framed as a suggestion grounded in the evidence rather than a directive. Size it to what the site could realistically do. The sample proposes adding varnish to an existing step of the well visit and names what the site would need to check first, such as payer rules and supplies.
