A tooth fracture extends into dentin without pulp exposure, located supragingivally. What Ellis classification does this represent?

Ellis Class I involves enamel only; Ellis Class II involves enamel and dentin without pulp exposure (matching this scenario); Ellis Class III involves enamel, dentin, AND pulp exposure; Ellis Class IV describes a non-vital tooth. The fracture's location (supragingival vs. subgingival) describes where it is, not which Ellis class it falls into.
