Maturation of primary and permanent teeth in preterm infants.

What Was Tested

Researchers studied Vitamin D and Calcium in this randomized controlled trial publication.

To elucidate the development of primary and permanent teeth and to interpret the effect of different calcium, phosphorus, and vitamin D supplementation in the neonatal period on dental maturation in preterm children.

Who Took Part

The study group was 30 children.

By PubMed's age tags, the people studied were infants, young children and children.

The maturity of the primary and permanent teeth was recorded in 30 preterm children.

Sixty children aged 2 years and 60 children aged 9-11 years served as controls.

How the Study Was Run

The design is described as randomized.

Because people in this Vitamin D study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Bone mineral content/density was assessed in the preterm infants.

What Was Measured

The subject headings attached to it are Bone Density, Calcium, Dentition, Permanent, Dietary Supplements, Infant, Premature, Longitudinal Studies and Milk, Human.

What This Means in Plain Language

The paper is a randomized study of Vitamin D and Calcium in 30 children.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

Results are reported in around 8 sentences of the abstract; we leave them to the paper itself rather than summarise them.

The publication is from 2000 (Archives of disease in childhood. Fetal and neonatal edition), a journal based in England.
