Investigation of Hypodontia as Clinically Related Dental Anomaly: Prevalence and Characteristics
The subjects were composed of 39.4% male and 60.6% female patients with no difference in gender distribution between the private local clinic and the university affiliated general hospital (Table 1). The mean age was 15.1 years, ranging from nine to 30 years.
The overall prevalence of hypodontia of permanent teeth, excluding the third molars, was 11.3%. The prevalence of hypodontia was 10.3% for the private local clinic and 12.2% for the university affiliated general hospital (Table 2). However, the difference between the two investigation centers was not statistically significant (95% CI for odds ratios: 0.966, 1.513).
