What will you find in a tooth affected by ankylosis according to its eruption path?

• A. Continuously erupting with normal positioning
• B. Submerging below the plane of occlusion
• C. Mobility due to loss of attachment
• D. Visible enamel defects

Answer: (B)

In cases of ankylosis, the tooth is fused to the underlying bone, which prevents it from erupting normally. As a result, the tooth will remain stationary while surrounding teeth continue their eruption. This leads to the affected tooth being submerged below the plane of occlusion, meaning it does not adjust its height along with adjacent teeth. Thus, as the opposing teeth erupt, the ankylosed tooth appears to sink or submerge, creating functional issues related to occlusion and potentially affecting the overall dental alignment.

Recognizing that ankylosis involves fusion of the tooth root to the jawbone helps clarify why continuous eruption or mobility due to loss of attachment would not occur in this scenario. Instead, the ankylosed tooth remains in its original position relative to its supporting structures, which further highlights the significance of understanding tooth movement patterns influenced by dental and periodontal health.
