Final answer:
Dental sealants are not considered a component of restorative dentistry; rather, they are a preventative measure to protect teeth from decay.
Step-by-step explanation:
The statement is False. Dental sealants are a preventative measure in dentistry rather than a restorative treatment. They are applied to the chewing surfaces of back teeth (molars and premolars) to prevent tooth decay. Sealants quickly bond into the depressions and grooves of the teeth forming a protective shield over the enamel of each tooth. While restorative dentistry involves the diagnosis, prevention, and treatment of oral diseases, as well as the restoration of decayed, damaged, or lost teeth, dental sealants serve as a protective measure to help prevent tooth decay before it occurs.
