Late discovery and location of unerupted supplemental premolars--at what age to screen?

The high prevalence of anomalies of number or form of teeth supports the principle that the developing dentition should be screened radiographically at least once. However, there is considerable controversy, as to when and how to screen, and increasing concern about risks from unnecessary radiation. This study presents a case of late discovery of supplemental premolars in a 14-year-old boy. Screening would have detected the supplementary teeth earlier; however, management of the patient would not have been significantly affected.
