What is the primary characteristic of the tongue's appearance in cases of Hairy Tongue?

1. Increased pigmentation

2. Elongated filiform papillae

3. Atrophy of papillae

4. Ulcerative lesions

The correct answer is: Elongated filiform papillae

In cases of Hairy Tongue, the primary characteristic is the elongation of the filiform papillae. This condition occurs when the filiform papillae, which are tiny projections on the surface of the tongue, become excessively elongated due to various factors such as poor oral hygiene, smoking, or dry mouth. The elongation gives the tongue a distinctive appearance, often described as "hairy," as the papillae can accumulate debris, food particles, and bacteria, leading to a darkened appearance as well. This characteristic can be further understood in the context of oral health; accumulation on the elongated papillae can lead to alterations in the normal flora of the mouth, potentially contributing to bad breath or a foul taste. Recognizing this feature is vital for dental professionals, as it can guide them in providing appropriate treatment recommendations for oral health improvement. The other choices refer to various conditions that can affect the tongue but do not specifically pertain to Hairy Tongue. Increased pigmentation, atrophy of papillae, and ulcerative lesions may present in other tongue conditions or diseases, but the hallmark of Hairy Tongue remains the elongation of the filiform papillae.
