Which of the following is a key function of dental hygienists during Phase 1?

Dental hygienists play a vital role in Phase 1 of dental treatment, which primarily focuses on preventive care and education. A key function during this phase includes consulting with medical providers and making referrals. This collaboration is important for ensuring comprehensive patient care, as it allows dental hygienists to address any medical conditions that may affect oral health or require coordination between medical and dental healthcare.

By engaging in consultation and referrals, dental hygienists can facilitate access to necessary medical interventions that complement dental care, promoting overall health. This function underscores the importance of an interdisciplinary approach in healthcare and highlights the hygienist's role as a vital member of the dental care team.

Other options involve procedures typically performed by dentists or specialists rather than dental hygienists. Root canal therapy, major restorative procedures, and oral surgery require advanced training and are beyond the scope of practice for dental hygienists, making the consulting and referral function a more accurate representation of their responsibilities during Phase 1.
