This document discusses Ellis Class I and II fractures, which involve enamel and possibly dentin fractures of teeth from direct impact. It notes that these fractures occur in 26-76% of cases and are usually caused by direct impact to the enamel. The document outlines the terminology used, clinical findings like crazing or patterns seen in enamel, and that radiographic imaging can identify fractures. It also briefly mentions provisional and definitive treatment options.
