Extracted teeth were collected from clinical procedures performed in the Faculty of Dentistry, National University of Singapore. A selected sample of 957 maxillary first premolars were subjected to visual examination and digital radiography. There was a higher incidence of two‐root form (50.6 per cent) than previously reported for the Singaporean dentition. In the two‐root category, 307 teeth exhibited the fused‐root form (two fused roots with two root canals) and 177 were distinctively of the two‐root form (two separate roots with two root canals and two foramina). The fused‐root form was emphasized as an entity in this study. The one‐root form accounted for 49.4 per cent. No three‐root form was detected.
