Timing of permanent tooth emergence in a Southeastern Dominican schoolchildren population sample.

The purpose of this study was to establish the mean timing of permanent tooth emergence in a low to middle socioeconomic level schoolchildren population sample from the Southeastern part of the Dominican Republic. A total of 900 children (15.6% of the 5-14-year-old schoolchildren from this city) were studied. Girls were relatively advanced in their emergence times except for the canine and second premolar in the maxilla and the first premolar in the mandible. The mean emergence times were, in general, relatively advanced when compared with those of United States whites and blacks, Danish, Canadian Eskimos, French-Canadians, Greenland Eskimos, Icelandics, Southern Chinese and South Africans.
