What is a characteristic of Class V Decay?

Class V decay is characterized by its location, specifically in the gingival third of any tooth. This type of decay occurs at the gum line and primarily affects the smooth surfaces of teeth, which can include both anterior and posterior teeth. Its development is often associated with factors such as inadequate oral hygiene, which allows plaque accumulation in these areas, leading to caries formation.

The gingival third is particularly susceptible due to challenges in cleaning in these areas, making it an important focus in preventive dentistry. The other choices describe different classifications of decay: Class I decay affects the occlusal surfaces, Class II affects interproximal regions, and Class IV involves decay extending to the incisal edge of anterior teeth. Class V is unique because it is not restricted to a specific type of tooth but instead refers to the location of the decay on the tooth's surface, thus accurately describing the characteristic of Class V decay.
