(Subject = 78).
A few adults were also examined andtreated.
As noted in the past, people of age >40 show a
considerable amountof periodontoclasia. A few
cases of arrested enamel development involving
the occlusal surface of molar teeth were noted,
probably dueto faulty nutrition during the formative period ofthe teeth.
No significant differences were found between
the Rongelap children and children of the same
age group onoutlyingislands in caries rate, eruption time, or morphology of theteeth. It was estimated that only about 10% of the Rongelap adults
practiced good oral hygiene.

raw data on all individuals are presented in the
appendices. The more heavily exposed Rongelap
group, who received 175 r, are designated as
“Rongelap exposed,” the Rongelap people who
received a smaller exposure of 69 r as “Ailingnae
exposed,” and the larger unexposed comparison
population of Rongelap as “unexposed.”’ Because
of the small number of people in the Ailingnae
group (15 examinedof 18), their data were not
treated as fully as those for the larger groups, and
are briefly summarized below in a separate para-
