What occurs during stage two of feline tooth resorption?

During stage two of feline tooth resorption, the defining characteristic is the loss of hard tooth tissue, specifically the enamel and dentin, without penetration into the pulp cavity. This stage signifies an ongoing pathological process where the tooth structure deteriorates, but the underlying pulp remains intact.

It's important to understand that the progression of tooth resorption can vary by stage, and while other stages might involve more severe loss, such as exposure of the pulp chamber or complete loss of the crown, this particular stage is focused on the integrity of the pulp, which remains protected. The distinction is crucial for proper diagnosis and treatment planning, as it impacts the approach to managing affected teeth in cats.

In contrast, the other choices reflect more advanced stages of resorption where the structural integrity of the tooth is significantly compromised, leading to more critical dental conditions that require immediate attention and different management strategies.
