Macrodontia is an uncommon dental anomaly that can present in both primary and permanent dentition. It has often been reported to occur concomitantly with other dental anomalies and has also been an established clinical characteristic of numerous systemic conditions and syndromes.
The following case reports illustrate the challenges of managing macrodont teeth in view of the various treatment options available, as well as the multiple factors that tend to influence each case individually.
Clinical Relevance: This article highlights the importance of early referral and a multidisciplinary approach to treating patients with dental anomalies.
Article
Macrodontia is the term given to teeth which are larger in size than the normal respective tooth type and have equally enlarged pulp morphology, crown and root. This dental anomaly may also be referred to as megalodontia or megadontia, and may be associated with numerous syndromes and medical conditions (Table 1). It can be present in both primary and secondary dentition.
The following distinctions have been made between the various types of macrodontia:
It must be remembered that small jaws in relation to the teeth might give the impression of generalized macrodontia. This concept still seems to create some controversy where early human remains are studied. Early dental dimensions classify as megadont teeth, but this might not be the case when one takes into consideration the small bodies of early human species.9
Isolated macrodontia have been reported to have a prevalence of 1.1% in the permanent dentition of British children in contrast to 2.5% in the Chinese population. The prevalence of macrodontia in the deciduous dentition is unknown. Males (1.2%) seem to have a higher predisposition than females (0.9%).10,11,12
