Dental hygienists can work in all sectors of dentistry, their role is twofold.
They have both clinical and health promotional responsibilities. Clinically they help to treat and prevent periodontal (gum) disease by scaling and polishing teeth, applying prophylactic and antimicrobial materials, they can take dental radiographs and undertake monitoring and screening procedures.
Their health promotional role includes motivating and encouraging individuals and groups in oral health practices, including oral hygiene and dietary advice. Dental hygienists are uniquely qualified to assist in the prevention and treatment of oral disease, focusing on oral health by monitoring hygiene practices and assisting the patient to develop a home care plan to maintain their oral health.
