Class IV decay is typically seen in which type of teeth?

Class IV decay specifically refers to carious lesions that occur on the incisal edges of anterior teeth—primarily the incisors and canines. This classification includes both the mesial and distal surfaces of these teeth that are visible when someone smiles or talks.

The anatomical structure of incisors allows for this type of decay to be more prevalent as they are used for cutting food and are more exposed to the oral environment, leading to increased chances of decay from factors such as diet and oral hygiene practices.

While decay can occur in all types of teeth, Class IV specifically pertains to the anterior teeth, which distinguishes it from decay that may affect molars or premolars, which would be classified differently. Understanding the classification of dental decay helps in the diagnosis and treatment planning for carious lesions, thus providing effective dental care.
