A clinical and radiographic survey of selected dental anomalies and conditions in a saudi arabian population

The prevalence rates of 10 selected dental anomalies were determined clinically and radiographically among 1,010 dental patients of Saudi Arabian nationality residing in Jeddah, Saudi Arabia. Results showed that hypodontia was the most prevalent (9.41%) followed by taurodontism (8.61%); microdontia (5.35%); and diastema (4.46%). Other anomalies were found at lower frequencies ranging from 0.20% for transposition to 1.19% for dilaceration. Comparing these results with other studies showed that these anomalies occur at different frequencies among various countries and communities in the world
