When extracting a primary maxillary incisor in which the root has been partially resorbed because of pres sure from its developing succe daneous tooth, which aspect of the remaining primary root will usually be longest and attached most securely to the gingiva?
1. Facial
2. Mesial
3. Lingual
4. Distal
Dental Anatomy
Answer: 1
In the case of primary teeth, the roots are often resorbed as the permanent teeth develop. The facial aspect of the root tends to be the last area to undergo resorption due to its position and the way the succedaneous tooth exerts pressure. The facial root surface is generally more stable and remains attached to the gingiva longer than the other aspects, making it the longest and most securely attached during extraction.
