A 5-year old child is recommended the following fluoride dentifrice regimen
**Core Concept**
The American Dental Association (ADA) recommends a fluoride dentifrice regimen for children to prevent dental caries and promote oral health. This regimen is based on the child's age and risk factors for dental caries.
**Why the Correct Answer is Right**
The ADA recommends a fluoride dentifrice with a concentration of 500-600 parts per million (ppm) for children between 2 and 16 years of age. This concentration is sufficient to prevent dental caries while minimizing the risk of fluorosis. The use of a fluoride dentifrice at an early age helps to strengthen tooth enamel and prevent the development of dental caries.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it may not provide sufficient fluoride concentration to prevent dental caries in children.
**Option B:** This option is incorrect as it may exceed the recommended fluoride concentration, increasing the risk of fluorosis.
**Option C:** This option is incorrect as it does not specify a fluoride concentration and may not provide adequate protection against dental caries.
**Clinical Pearl / High-Yield Fact**
The ADA recommends a fluoride varnish application every 6 months for children at high risk of dental caries, in addition to a fluoride dentifrice regimen.
**Correct Answer: C. 500-600 ppm fluoride concentration**
