Where is the most common location for irritation fibromas to occur?

The most common location for irritation fibromas to occur is indeed the buccal mucosa along the plane of occlusion. This area frequently experiences mechanical irritation due to habitual activities such as biting of the cheeks or the presence of dental appliances. When soft tissues are subjected to repeated trauma, it can lead to localized hyperplasia, forming fibromas.

Irritation fibromas are benign nodular growths that represent a reaction to chronic irritation. The buccal mucosa is particularly susceptible due to its anatomical position and exposure to the constant forces applied during mastication. This makes it a prime site for the development of these fibrous growths.

Other potential locations listed, such as the palate, gingiva, and floor of the mouth, are less commonly associated with irritation fibromas. While these areas can develop various oral lesions, the buccal mucosa aligns more consistently with the development of irritation fibromas related to the sources of chronic mechanical irritation typically observed in the oral cavity.
