What happens to the lamina dura as a tooth begins to erupt?

• A. It becomes thicker
• B. It remains constant
• C. It thickens and then thins
• D. It completely disappears

Answer: (A)

As a tooth begins to erupt, the lamina dura, which is the dense bone surrounding the tooth socket, experiences changes as it facilitates the tooth's movement through the bone. During this process, the lamina dura becomes thicker. This thickening occurs due to the increased activity of osteoblasts, which are bone-forming cells, as they work to accommodate the erupting tooth. The enhanced density and thickness of the lamina dura provide additional support and stability as the tooth emerges into the oral cavity. While options suggesting that the lamina dura remains constant, thickens and then thins, or completely disappears may seem plausible in different contexts, they do not accurately reflect the physiological process that occurs during tooth eruption. The growth and remodeling of the lamina dura are crucial to ensure the proper alignment and anchoring of the tooth as it emerges and establishes itself within the dental arch.
