Question

In primary molars, radiographic bony changes from

an infection are initially seen
A. at the apices.
B. in the furcation area.
C. at the alveolar crest.
D. at the base of the developing tooth.

Answer 1

Radiographic bony changes from an infection in primary molars are initially seen in the furcation area. This is where infection can spread and cause changes visible on dental X-rays. Dental caries that reach the pulp can lead to infections and abscesses if left untreated.

Step-by-step explanation:

In primary molars, radiographic bony changes from an infection are initially seen in the furcation area. This area is susceptible to the spread of infection due to its anatomic configuration and its proximity to the pulp chambers of multi-rooted teeth. Dental X-rays can reveal these changes and are essential tools for the diagnosis of dental pathology. Untreated caries can lead to infection of the pulp and subsequently the surrounding bony structures, potentially resulting in abscess formation.

The crown and root of a tooth are vital in understanding where pathological changes might occur. The crown is protected by enamel and the root by cementum; beneath both is the dentin, and within is the pulp cavity. Should dental caries progress through the enamel and dentin of primary molars, they can reach the pulp and affect the furcation area, seen radiographically.
