Step-by-step explanation:
The dental cement that contains oil of clove and has a sedative effect on the dental pulp is D) zinc oxide-eugenol. The eugenol, which is a component of oil of clove, is primarily responsible for the soothing effect this cement has on the pulp.

- Glass ionomer is known for its chemical bond to both enamel and dentin and its fluoride release properties.
- Zinc phosphate cement has been traditionally used as a luting agent due to its long history and mechanical properties.
- Composite resin is used in dental bonding and as a restorative material for its aesthetic properties and versatility.
- Zinc oxide-eugenol has a sedative effect on the pulp and is often used as a temporary filling or cementing medium.
