What feature is characteristic of angular cheilitis in denture wearers?

In denture wearers, low vertical dimension is a characteristic feature of angular cheilitis. Angular cheilitis refers to inflammation and cracking at the corners of the mouth, which can be exacerbated by several factors associated with denture use. Low vertical dimension, which occurs when the bite is not properly aligned or the dentures don’t fit properly, can lead to excessive stretching of the tissues at the corners of the mouth. This stretching can create a conducive environment for the development of angular cheilitis, as moisture and bacteria can accumulate in this area, leading to irritation and infection.

While factors like poor oral hygiene may contribute to oral health issues, they are not specifically characteristic of angular cheilitis in the context of dentures. Similarly, vitamin deficiencies, such as vitamin C, can affect overall health but are not directly linked to angular cheilitis in denture wearers. High temperatures can occur in various conditions but do not serve as a typical feature related to this specific condition. Therefore, understanding the role of vertical dimension is crucial in recognizing and addressing angular cheilitis in individuals with dentures.
