The eruption age maxillary permanent lateral of incisor is:
**Core Concept**
The eruption age of permanent teeth is a critical aspect of pediatric dentistry and orthodontics. The eruption time of permanent teeth can vary significantly among individuals, but it follows a generally accepted range. This knowledge is essential for predicting the timing of orthodontic interventions and assessing the development of the dentition.
**Why the Correct Answer is Right**
The eruption age of the maxillary permanent lateral incisor typically ranges from 8 to 12 years of age. This tooth erupts after the maxillary central incisors and canines, but before the premolars. The eruption of this tooth is influenced by the development of the surrounding bone and the eruption of the adjacent teeth. As the maxillary permanent lateral incisor erupts, it can cause changes in the occlusion and the alignment of the teeth.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the eruption age of the maxillary permanent lateral incisor is typically older than 7 years.
* **Option B:** This option is incorrect because the eruption age of the maxillary permanent lateral incisor is typically younger than 15 years.
* **Option C:** This option is incorrect because the eruption age of the maxillary permanent lateral incisor can vary, but it is generally not older than 13 years.
**Clinical Pearl / High-Yield Fact**
The eruption age of permanent teeth can be influenced by genetic and environmental factors. A delay in the eruption of permanent teeth can be an indicator of systemic diseases such as hypothyroidism or celiac disease.
**Correct Answer: D. 10-11 years.**
