enamel spindle

Enamel tufts should also not be confused with the similar enamel spindles.

Enamel spindles are often confused with two other entities: enamel lamellae and enamel tufts.

Enamel spindles are also linear defects, similar to lamellae, but they too can be found only at the dentinoenamel junction, similar to enamel tufts.

Enamel spindles are "short, linear defects, found at the dentinoenamel junction (DEJ) and extend into the enamel, often being more prevalent at the cusp tips."

Enamel spindles are also linear defects, but they too can be found only at the DEJ, because they are formed by entrapment of odontoblast processes between ameloblasts prior to and during amelogenesis.
