Which type of decay is specifically referred to as Smooth surface decay?

Smooth surface decay specifically refers to Class V decay. This type of dental caries occurs on the smooth surfaces of the teeth, which are typically found in areas that are not in contact with occlusion or adjacent teeth, such as the facial and lingual surfaces of the anterior teeth and the gingival third of posterior teeth. Class V restorations are primarily used to restore these smooth surface lesions, highlighting the importance of identifying and addressing decay in these areas early to prevent further complications.

In contrast, other classes of decay focus on different surfaces and types of cavities. For instance, Class I decay involves pits and fissures mainly found on the occlusal surfaces of molars and premolars, while Class II decay affects the proximal surfaces of posterior teeth. Class IV involves decay on the proximal surfaces of anterior teeth that also includes the incisal edge. Understanding these distinctions is crucial for effective dental assessment and treatment planning.
