  1. Class IV

  2. Class I

  3. Class II

Option A, Class IV, refers to a restoration on the incisal edge of an anterior tooth. Option B, Class I, refers to a dental filling on a single surface of a tooth. Option D, Class V, is used for a restoration on the gingival 1/3 of a tooth, usually found on the facial or lingual surface.
