The term “hypo-hyperdontia” is used to describe condition in which agenesis of some teeth are seen to occur simultaneously with supernumerary teeth within the same individual. Supernumerary teeth may resemble the permanent teeth sometimes but generally are of different shape and size. These teeth may remain embedded in the alveolar bone may cause disturbance to the developing teeth or can erupt into the oral cavity. Contrary to the presence of extra tooth in arch few complement of the teeth were missing in the arch indicating presence of concomitant hyper hypodontia. The erupted or unerupted tooth might cause aesthetic and/or functional problems especially if it is situated in the maxillary anterior region. Recently, many genetic studies have been conducted to explore these developmental anomalies. This case reports a unique case of presence of supplemental supernumerary maxillary central incisor with hypodontia of both lower central incisors, which is a rare finding and a literature review, is presented about hypohyperdontia in the dentition.
