Question: 1 / 1390

Which factor is considered a common origin for Class V lesions?

In lingual pits

In buccal fissures

Poor oral hygiene

Class V lesions, often referred to as cervical caries or non-cavitated lesions, are commonly associated with cervical areas of teeth near the gum line. Poor oral hygiene plays a pivotal role in the development of these lesions. When plaque and biofilm accumulate due to inadequate brushing and flossing, they can lead to demineralization of the enamel and cementum in this area, which is typically more vulnerable to carious activity.

Unlike the factors of lingual pits or buccal fissures, which are specific anatomic locations where caries may occur, poor oral hygiene is a more generalized condition that sets the stage for caries development across many tooth surfaces, particularly in Class V zones. Furthermore, while occlusal issues can contribute to other types of dental problems, they are not a predominant factor in the development of Class V lesions specifically.
