Oral and dental findings in a child with growth hormone insensitivity syndrome.

Growth hormone insensitivity syndrome, also known as Laron syndrome, is an autosomal recessive disorder caused by defects the of growth hormone receptor gene and may lead to increased growth hormone levels. This syndrome's main clinical features are: dwarfism; acromicria; organomicria; cervical spinal stenosis; early osteoarthritic changes of the atlantoaxial joint; small oropharynx; decreased growth velocity; insulin resistance; hypoglycemia; delayed skeletal maturation and osteoporosis; and muscular and central nervous tissue underdevelopment. The facial bones, especially sphenoid and mandibular, are also underdeveloped.

Dental fluorosis: exposure, prevention and management.

Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of physical activity, nutritional factors and bone growth. The risk period for esthetic changes in permanent teeth is between 20 and 30 months of age.
