Non-syndromic hypo-hyperdontia in the mandibular anterior region with absence of all four-third molars - A rarity

Abstract

Numeric disturbances in the human dentition are quite a common occurrence in the general population. When less than the normal complement of teeth develops, it is termed as hypodontia, whereas hyperdontia is a condition with an excess number of teeth developing. Therefore, though both conditions manifest as changes in the number of teeth, they represent the opposite ends of the spectrum in the development of the dentition. The literature contains numerous reports of the exclusive occurrence of these anomalies; however coexistent oligodontia, hypodontia, and supernumerary teeth or hyperdontia is a rare manifestation of the human dentition.
