| Abstract | ||
| Background: Agenesis of third molar (3M) is one of the most common human dental anomalies. Estimates range from 9% to 32 %, among different populations. The aim of the study was to find its prevalence among Iraqi patients attending the College of Dentistry and the Consultant Clinic in Baghdad University. Materials and method: A total of 200 orthopantomographs were involved in this study to evaluate the presence or absence of third molars (128 females, 72 males). The age of the subjects ranged between 10-25 years. Results: The prevalence of third molars' agenesis was 24% of the whole sample (25.8 % in females 20.8% in males) with no significant difference between males and females. Maxillary (3M) agenesis is significantly more frequent than mandibular (3M) agenesis (P<0.001). The study also showed that it is more frequent to find one missing than two missing third molars, and that the sequence of frequency of missing third molar is one, two, four and three. Conclusion: No gender difference regarding (3M) agenesis, with a significant maxillomandibular difference | ||
