Gemination and fusion are the most commonly encountered anomalies in dental practice, and distinction between the two is always challenging. Fusion is when two tooth buds fuse to make a large tooth. Gemination, also called double tooth is an anomaly exhibiting two joined crowns and usually a single root. It represents an incomplete attempt of a single tooth germ to split. It is considered multifactorial in etiology, with genetic and environmental causes. It is extremely difficult to differentiate between fusion and germination especially when a supernumerary is attached with the adjacent tooth. This paper highlights the importance of diagnosing developmental anomalies of teeth and the proper treatment outcome of these abnormalities. https://biomedpharmajournal.org/vol9no3/gemination-or-fusion-a-case-report/ Gemination fusion
