Tooth gemination [also known as schizodontia, twinning, or double teeth] occurs when a single tooth germ splits during development. [1] Splitting of the tooth may be partial or complete. If the splitting is complete, the extra tooth is known as a supernumerary tooth . [ 2 ]
The fusion of two deciduous teeth. Gemination occurs when a developing tooth incompletely splits into the formation of two teeth. Fusion is the union of two adjacent teeth during development. Concrescence is the fusion of two separate teeth only in their cementum.
The primary teeth typically erupt in the following order: (1) central incisor, (2) lateral incisor, (3) first molar, (4) canine, and (5) second molar. [45] As a general rule, four teeth erupt for every six months of life, mandibular teeth erupt before maxillary teeth, and teeth erupt sooner in females than males. [46]
In phonetics and phonology, gemination (/ ˌ dʒ ɛ m ɪ ˈ n eɪ ʃ ən / ⓘ; from Latin geminatio 'doubling', itself from gemini 'twins' [1]), or consonant lengthening, is an articulation of a consonant for a longer period of time than that of a singleton consonant. [2]
Fused teeth tend to have separate pulp chambers and root canals, unlike in tooth gemination which tends to have a single pulp chamber and root canal.However, the degree of separation will depend on where & when the fusion occurred so the pulp chamber and/or root canal may be completely fused into one.
Occasionally, additional teeth may also arise from developmental anomalies like fusion or gemination. Fusion occurs when two tooth buds fuse together, creating a single, larger tooth. Gemination involves the incomplete division of a single tooth bud into two teeth. In some cases, these anomalies may take the form of the appearance of extra teeth.

For teeth with necrotic pulp and mature apex, conventional root canal therapy could be done and restored. [4] For teeth with necrotic pulp and immature apex, MTA root-end barrier could be carried out. Glass ionomer layer and composite could be used to restore the tooth. [4] If there is occlusal interference, the opposing projection should be ...
