Is there a relationship between increased tooth number and increased tooth size? a case report

A number of dental anomalies exist that involve the formation of increased amounts of hard tissue. In particular, these include both macrodontia and supernumerary teeth, which appear to occur as distinct entities.1 Macrodontia or increased tooth size can be classified as true or relative, and can be generalized or isolated.2 The incidence of macrodontia in the permanent dentition ranges from 1.1% to 1.9%, depending upon the population studied,3^,4 but is more common in the primary dentition.3 Supernumerary teeth are those present in addition to the normal complement within the dentition and occur with an incidence of around 0.1–3.8%, being more common in the permanent dentition.5 Despite these fundamental epidemiological differences, a number of features are seen that are common between these two conditions, which include a higher prevalence in males than females,3^,5 unilateral or bilateral distribution,5^,6 and occurrence within both dental arches.5^,6^,7 Both genetic and environmental factors have been implicated in the aetiology of both anomalies.8^,9
