title: Labial hypoplasia of primary canines in black Head Start children.
abstract: During routine examinations of 334 black Head Start children in Mississippi, many presented with areas of hypoplasia on the labial surfaces of the mandibular primary canines. Mean prevalence was 38 percent in fluoridated areas and 36 percent in areas without fluoridation. As it appears that hypoplastic defects have a strong potential to become carious, one should expect that the incidence of 25 percent reported here would continue to increase.
