Which of the following statements about fissured tongue is false?

The statement regarding the prevalence of fissured tongue being in the range of 12%-15% is considered false because the estimated prevalence is actually higher than this range, with studies indicating that it can be found in as much as 2-5% of the general population. This condition, characterized by grooves or fissures on the surface of the tongue, does indeed exhibit some variability in prevalence across different populations and age groups.

In contrast, the other statements are accurate. The prevalence and severity of fissured tongue do indeed increase with age; older individuals tend to exhibit more pronounced fissuring. Additionally, fissured tongue has been associated with various syndromes, including Melkersson-Rosenthal syndrome, which is characterized by a triad of symptoms including facial swelling, fissured tongue, and a form of facial paralysis. Furthermore, research has suggested that there may be a hereditary component to fissured tongue, indicating that genetic factors might play a role in predisposing individuals to this condition.

Understanding these associations and epidemiological factors is crucial for dental professionals, as they help in recognizing fissured tongue and differentiating it from other oral conditions.
