ABSTRACT
Variation in size, form and morphology of the teeth result in anomalies such as macrodontia, microdontia, hyperdontia, hypodontia, double tooth, taurodontism and dens in dente. While traits that may occur more commonly in certain ethnic groups may be considered to be specific to that population. The characteristics of these anomalies and traits are presented along with the prevalence figures for their occurrence in primary dentition of southern Chinese.

Dental anatomical anomalies having a significant impact on endodontic diagnosis and treatment are the talon cusp, tuberculated premolars, three-rooted mandibular molars, and C-shaped molars. Asian and Pacific Islander ethnic groups have the highest percentage of these dental anatomical anomalies compared to the general population. As the population of Asians and Pacific Islanders continues to grow in California and other western states, dentists should be aware of the diagnostic and treatment complexities associated with specific patient groups.
