Which population percentage is affected by geographic tongue?

Geographic tongue, also known as benign migratory glossitis, is a common condition that affects a notable percentage of the population. The correct answer indicates that approximately 2% of the population is affected by geographic tongue. This condition is characterized by irregular patches on the tongue's surface that can appear to move or change over time.

Research consistently shows that geographic tongue occurs with varying prevalence, with estimates ranging generally from 1% to 3%. While it's important to keep in mind that the percentages can vary in different studies, the figure of 2% is widely recognized as a representative estimate.

Additionally, geographic tongue is often seen in association with other conditions such as psoriasis or other inflammatory diseases, which can lend insight into its prevalence in certain populations. The condition is generally benign and asymptomatic, which may contribute to the variations in reported prevalence, as individuals might have it without being aware.

Other percentages such as 1%, 5%, and 10% either understate or overstate the commonality of geographic tongue in the general population, as research indicates the prevalence is typically in the lower range of the estimates given.
