[4] [2] If a double tooth is present, then there may be a higher chance of other dental anomalies (see Related Abnormalities section). [1] [5] Double teeth are usually larger than normal teeth, may have an incisal notch present on the crown of the tooth, and may have a groove/fold in the enamel on the labial surface that can extend further down ...
Mader’s “two-tooth” rule can help distinguish between tooth fusion and gemination. If the double tooth is counted as two teeth and the number of teeth in the mouth is increased, then the double tooth is likely due to tooth gemination. [1] If the double tooth is counted as two teeth, and the number of teeth in the dental arch is normal ...
A systematic review concluded that for decayed baby (primary) teeth, putting an off‐the‐shelf metal crown over the tooth (Hall technique) or only partially removing decay (also referred to as "selective removal" [5]) before placing a filling may be better than the conventional treatment of removing all decay before filling.

Bulbous crowns are common with pronounced cervical constriction; All teeth in the mouth are affected, with severe abnormalities present in both the baby (primary) and adult (permanent) teeth. This is in contrast to type I where the presentation is more variable; Rarely, individuals exhibit sensorineural hearing loss.
According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
Tooth ankylosis refers to a fusion between a tooth and underlying bony support tissues. In some species, this is a normal process that occurs during the formation or maintenance of the dentition. [1] By contrast, in humans tooth ankylosis is pathological, whereby a fusion between alveolar bone and the cementum of a tooth occurs.
