[Bilateral tooth fusion].
BACKGROUND
Tooth fusion is the union of two adjacent germs at any stage of their development. It is a rare phenomenon which can present uni- or bilaterally and affects the maxilla more often.


METHODS
A male patient, 25 years of age, presented with a bilateral maxillary fusion of tooth 11 and supernumerary tooth 11, as well as teeth 21-22. Retroalveolar images confirmed the bilateral fusion with a bifide crown and a single root for 11 and a bifide crown separated by a central groove with two diverging roots. No esthetic and/or functional impact was noted and no specific treatment was initiated.


CONCLUSIONS
Fusion is a dental development anomaly with a relatively weak esthetic and/or functional impact. But some dental lesions can appear, parodontal diseases, a shortened arcade, a delayed tooth growth, an ectopy of permanent teeth, etc. An adapted treatment should be initiated with the aim of separating fused teeth and restoring their functional and esthetic features.
