**Question:** Eruption of Deciduous Maxillary Canine occur at

A. 6 months
B. 9 months
C. 18 months
D. 2 years

**Core Concept:** Eruption of teeth is a crucial part of dental development, which refers to the process of teeth becoming visible in the oral cavity from their position within the gums. In children, this process begins during fetal development, but the actual visible eruption occurs postnatally. Deciduous teeth, also known as baby teeth, have distinct eruption times compared to permanent teeth.

**Why the Correct Answer is Right:** The eruption of deciduous maxillary canine usually occurs during the second year of life. In this case, the correct answer is D. 2 years.

Deciduous teeth, including the maxillary canine, typically erupt in an orderly sequence. The eruption of the maxillary canine starts after the eruption of the central incisors, lateral incisors, and primary second molars. This sequence ensures that the teeth have enough space to erupt properly and facilitates proper dental occlusion and jaw alignment.

**Why Each Wrong Option is Incorrect:**

A. 6 months is too early for the eruption of the maxillary canine as it starts after the eruption of other primary teeth.
B. 9 months is also too early, as the eruption process is not complete by this time.
C. 18 months is slightly closer to the correct answer but still too late as the eruption process should be complete by then.

**Clinical Pearl:** The eruption sequence of deciduous teeth is crucial for proper dental development and overall oral health. Understanding these sequences helps dental practitioners anticipate the timing of tooth eruption and provide appropriate care for children.
