Unerupted maxillary anterior supernumerary teeth: report of 204 cases. 1984

F Tay, and A Pang, and S Yuen

Two hundred and four cases of unerupted maxillary anterior supernumerary teeth were found among Hong Kong school children between the ages of six to 9.5 years. The anomaly was prominent in the male with a sex ratio of 5.4:1. There was no significant difference in the distribution of unilateral and bilateral supernumerary teeth, between the two sexes. Most of the supernumeraries were located within the central incisor region. The inverted type was found to be associated with bodily displacement, median diastema and torsiversion, while the normally oriented ones were related to delayed eruption. The association of maxillary anterior supernumeraries with clinical symptoms was compared with studies on Caucasian populations, and guidelines were described for their early diagnosis.
