Which surfaces are affected in Class I Decay?

Which surfaces are affected in Class I Decay?

• A. Facial or lingual surfaces
• B. Proximal surfaces of premolars
• C. Pits and fissures of occlusal surfaces
• D. Occlusal surfaces only

Answer: (C)

Class I decay specifically refers to cavities that occur in the pits and fissures of teeth. This typically affects the occlusal surfaces of molars and premolars, where these anatomical features are most pronounced. The reason for this classification is due to the complexity and depth of these pits and fissures, which can trap food particles and bacteria, leading to higher susceptibility to decay. Understanding the classification is essential in identifying the location and type of decay present, allowing for appropriate prevention and treatment strategies. While other surfaces such as facial, lingual, and proximal surfaces can experience decay, those fall under different classifications (such as Class II for proximal surfaces), and Class I specifically highlights the importance of managing occlusal decay effectively.
