[Content of fluoride and magnesium in permanent teeth of children and adolescents with constitutional delay of growth and development].
BACKGROUND
The objective of this study was to determine the content of fluorides and magnesium in permanent teeth of children and adolescents with constitutional delay of growth and development (CDGD) and to correlate the findings with susceptibility to caries.


METHODS
Our study group consisting of 20 patients with CDGD, aged 11 to 20 years, was compared with an age-matched control group of 20 normal subjects. Dentition status was assessed according to the average DMFs score. Acid biopsy of enamel on the labial surface of incisors was done to measure the content of calcium, magnesium, and fluorides. CDGD patients demonstrated a higher average DFs value and less permanent teeth than their normal counterparts.


RESULTS
Microanalyses of enamel showed that the depth of the acid biopsy was similar in all subjects. The content of fluorides and magnesium in enamel was lower in patients with CDGD.
