**Question:** A 10-year-old child reports with Loss of primary lower 2nd molar. His occlusion is normal. The clinician should:

**Core Concept:**
In children, the eruption sequence of deciduous teeth follows a specific order. The primary lower second molar (P2) typically erupts between the ages of 6 and 8 years, and will be lost sometime between 9 and 13 years due to the eruption of permanent molars.

**Why the Correct Answer is Right:**
In this scenario, the clinician should focus on evaluating the primary dentition, as the child has lost the P2. Since the child's occlusion is normal, there is no immediate concern for malocclusion or improper tooth alignment.

**Why Each Wrong Option is Incorrect:**
A. Assessing the permanent dentition (P2 has already been lost) is unnecessary and irrelevant in this case.
B. Evaluating occlusion for malocclusion due to P2 loss is not essential as mentioned, as the occlusion is normal.
C. Evaluating for eruption of permanent teeth (P2 has already been lost) is irrelevant.
D. Evaluating occlusion for malocclusion due to P2 loss is not essential as mentioned, as the occlusion is normal.

**Clinical Pearl:**
In children with missing primary teeth (like P2), occlusion should be assessed for malocclusion when the primary tooth loss occurs or shortly after, before the permanent tooth eruption distorts the occlusion. However, in this case, the child's occlusion is normal, so no immediate intervention is needed. This highlights the importance of monitoring occlusion in children with missing primary teeth and the need for a thorough understanding of the primary dentition eruption sequence.

**Correct Answer:**
B. Assess the occlusion for malocclusion due to primary tooth loss (P2 has already been lost).
