Teething

The age of eruption

The age of tooth eruption is 6-8 months. That single number is what the paper asks for, and it is asked as one part of an infant scenario that also asks you to estimate the developmental age and to name a primitive reflex that should be absent in him.

Delayed teething: rickets

Delayed teething and caries are head findings of rickets, and they never stand alone. Vitamin D deficiency in children is rickets; in adults the same deficiency is osteomalacia.

The examination of the child is set out by part:

• Head: craniotabes, a thinning of the skull bones, for which you press for 30 seconds to check; delay closure of the Ant. Fontanelle, which is also large; delayed teething and caries; hair loss in the type 2 vit D dependent ricket form
• Extremities: bowing of legs, put both malleoli together, more than 10 cm; short stature; widening of wrist and ankle, the double malleoli, in the walking or crawling child; lax ligaments
• Muscles: hypotonia, which delays walking, and pot belly
• Thorax: Rickets Rosari, a thickening of the costrochondal joint; pigeon chest, that is pectus carinatum, a sternum protrusion; Harrison Sulcus, a depression along the line of diaphragmatic insertion into the rib cage; kyphoscoliosis

Rickets is treated with Ca and vitamin D. Too much of the vitamin has its own picture: kidney stones, dementia, constipation, abd. pain and depression.
