You practice dental hygiene in a low socioeconomic (SES),
multicultural city with a population of 1.5 million.
However, the office where you are employed serves a relatively
higher SES population of the city. The city water supply is not
fluoridated; consequently, dental caries is prevalent in the
community. Most families in the city are of Hispanic descent.
You recently assisted the public health dental hygienist in
conducting a screening on the children in a local Title I elementary
school to document their oral health status. Fluoridation was
defeated 10 years ago because of a strong antifluoridation
campaign. Fluoridation will be on the ballot again in 8 months. The
natural level of fluoride (F) in the community water is 0.2 mg/L. -

health to the parents
c.) Phoning the parents to report findings of the screening on
their children and refer them for treatment
d.) Sending Basic Screening Survey results home with a referral and

correct answer ✅▪️The Basic Screening Survey (BSS) is an easy tool
used for screening that includes an assessment of the immediacy of
treatment needs (emergency care, treatment is necessary, or
routine care is recommended).
➖The DMFT is more complex, provides more detail than is
required for screening, and would not yield results that would be
easily understood by the parents.
➖Local community clinics provide the best fee for service for low-
income patients, and a Title I school has a high percentage of
children from low-income families. It is difficult to reach people by
phone, and a follow-up list for referral is important to the screening
process for ethical reasons.
