Abstract:
Several causes of eruption disturbances in upper permanent central incisors have been described. This report describes six cases in which the failure of maxillary permanent central incisors to erupt appears to be associated with developmental anomalies in the adjacent permanent lateral incisors. The root formation of the unerupted central incisors was delayed in comparison to the contralateral incisors as was the development of the adjacent lateral incisors. The shapes of the crowns were abnormal and in five cases out of the six described, the primary predecessors of the unerupted incisors were fused.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
