Kaplan Medical Kaplan Pediatric Qbook Questions

two pediatric questions from Kaplan CK Question Book
1) A 1 year old boy is brought to the physician for a well child examination. He has not had any significant illness and appears normally developed. His immunizations are update. Oral examination reveals multiple chalky-white spots on the enamel surface of the maxillary incisors.

2) An otherwise healthy 8 year old girl presents with intrinsic yellow-brown stains of the tooth enamel, affecting multiple teeth. According to her parents, the child's oral hygiene has been consistently scrupulous.


Select the most appropriate measure that could have prevented the above conditions.

A) Administration of vitamin supplements
B) Avoidance of tetracycline before age 8
C) Effective maternal oral hygiene during pre- and postnatal period
D) Prenatal administration of fluoride supplements
E) Prevention of thumb and finger sucking

confused about the first answer....would be grateful if anyone can explain it....i've added the second one just for completion

hi
1. dental caries... according to recent studies up to 50% children have decay in their primary tooth. First stage manifests with chalky white areas on the tooth enamel. the most freq associated teeth are maxillary incisors. Appropriate dental care should begin from the time of eruption of first teeth. Caries is an infectious disease , in which strep mutans plays crucial role, and since its transmitted to infant by caretaker , so effective dental hygiene by the mother in the prenatal and postnatal period is must to reduce transmission. the child's teeth should be cleaned every day with tooth brush or damp cloth from the moment they erupt . Finally night feeding should be avoided as soon as possible.

2. Intrinsic stains of tooth enamel are most commonly caused by two conditions: excessive intake of fluoride supplements and administrations of tetracyclines during the age of tooth formation ie before 8 yrs of age.
fluoride supplements prevent tooth decay or its progression. if fluoride conc in community water supply is <0.6 ppm/l , supplemental dietary fluoride shud be provided from 6 m to 16 yr of age.

hope this helps:-)
