Fusion of primary teeth- An odontogenic anomaly

The conjoining or twinning of teeth leads to odontogenic anomalies. The dental fusion is observed by the union of two normally separated tooth germs. It is defined as the union of two independently developing primary or permanent teeth that results in the formation of a single large tooth. It can be complete or incomplete, depending upon the stage of development of teeth at the time of union. The prevalence of this anomaly is <1% in primary dentition and is commonly observed in incisor‑canine region.
