The ‘ugly duckling stage’ is characterized by:

 # The ‘ugly duckling stage’ is characterized by:

A. Distoangular axial inclination of the crown of maxillary incisors

B. Deep overbite

C. Mandibular lateral incisors erupting lingual to mandibular central incisors

D. Maxillary lateral incisors erupting lingual to maxillary central incisors

The correct answer is A. Distoangular axial inclination of the crown of maxillary incisors.

In some children, the maxillary incisors flare laterally and are widely spaced when they first erupt, a condition often called the "ugly duckling" stage. The position of the incisors tends to improve when the permanent canines erupt, but this condition increases the possibility that the canines will become

impacted.

A. Solitary or multiple small radiolucent areas

Radiographic Features

Radiodensity—about 10 days after acute infection, the density of trabeculae will be decreased, with blurred and fuzzy. For the radiographs to reveal any changes, there must be a loss of from 30 to 60% in the calcium content.

Trabecular pattern—the earliest radiographic change is that trabeculae in the involved area are thin, of poor density and slightly unsharp or blurred. The trabeculae soon lose their continuity as well as the little density present. Individual trabeculae become fuzzy and indistinct.
