In a class I preparation, are marginal ridges involved?

Explanation:
In a Class I preparation, the focus is on removing caries from pits and fissures of the occlusal surface. The marginal ridges form the borders around the occlusal table, and they are preserved in a typical Class I outline to maintain tooth strength and occlusal anatomy. You would only involve a marginal ridge if caries or structural damage extended into that area, requiring its removal to access and restore the tooth. Therefore, the statement is false.
