Hypodontia

Hypodontia is characterised by one or more absent teeth. Hypodontia is the most common developmental anomaly amongst humans. The third molars, which are often missing, are not considered as hypodontia but simply as a variation of the norm. Hypodontia is more frequent in permanent dentition than in primary dentition and more frequent in males than in females. Often the patients with hypodontia also have smaller or peg-shaped teeth.
