What task can dental hygienists perform concerning pit and fissure sealants?

Dental hygienists are specifically trained to apply and adjust pit and fissure sealants as part of their preventive care activities. This procedure is critical in preventing dental caries in children and vulnerable populations by filling the deep grooves and pits on the chewing surfaces of molars, thereby creating a smoother surface that is easier to clean.

The application of sealants is typically within the scope of practice for dental hygienists, as it aligns with their role in promoting oral health and carrying out preventive treatments. They can assess the need for sealants, apply them, and make necessary adjustments to ensure an optimal fit and effectiveness.

In contrast, administering nitrous oxide, monitoring sedated patients, and performing extractions are not tasks that fall under the typical responsibilities of dental hygienists. These procedures require additional training, certification, or are reserved for dentists, highlighting the specific focus and skill set that dental hygienists maintain in their practice. Hence, the ability to apply and adjust sealants is both within their scope of practice and is a key component of preventive dental care.
