Clinical features of early-onset periodontitis.

The authors estimate the prevalence of early-onset periodontitis, or EOP, in U.S. adolescents and describe the clinical features that occur at an early stage in those who have EOP. In 1986 and 1987, about 10.0 percent of African-American, 5.0 percent of Hispanic and 1.3 percent of white U.S. adolescents had EOP. Clinical features that may be useful in the early detection of EOP include overt gingival inflammation, dental calculus and a high rate of caries, restorations and tooth loss.
