Bilateral macrodontia of mandibular second premolars: a case report.

Macrodontia of single teeth is rare. This has been reported on only six occasions in scientific journals when affecting mandibular second premolars with associated morphological anomalies. The large crown size causes problems with eruption, and disrupts the dentition. There are consequent inherent difficulties for the extraction of these teeth. Once erupted, their anatomy predisposes them to caries. Most cases are seen in children, before interventive surgery has been completed. The morphological anomalies of these premolar Macrodonts appear quite distinct and may justify a separate unique categorization.
