Resumen
BACKGROUND: The custom of canine bud removal has detrimental consequences on children's general health and dental care. The objective of this study was to assess whether the prevalence of missing primary canines and dental defects in offspring of emigrants from Ethiopia is greater than in offspring of native Israeli parents of similar socioeconomic class. METHODS: 477 children of Ethiopian descent and 317 offspring of native Israeli parents, from 21 nursery schools and kindergartens, underwent dental examinations aimed to determine the presence or absence of primary canines and of developmental enamel defects on adjacent teeth to the primary canines. For purposes of analysis, children were classified into two age groups: younger (ages 18-48 months) and older (ages 49-82 months). RESULTS: Canines were present in more Israeli than Ethiopian younger children, 87.5 percent vs. 42.3 percent, p=0.0001; and in more Israeli than Ethiopian older children, 92.6 percent vs. 40.4 percent, p=0.0001. More dental defects were detected in Ethiopian than in Israeli younger children, 32 percent vs. 3.9 percent, p=0.0001; and in more Ethiopian than Israeli older children, 31.2 percent vs. 5.8 percent, p=0.0001. CONCLUSIONS: The prevalence of missing primary canines and dental defects was greater among offspring of parents who had emigrated from Ethiopia 15-20 years earlier than among offspring of native Israeli parents living in the same low socioeconomic neighborhoods.
