hygienista

Hygienista is a term used in several languages to denote a health professional focused on hygiene and disease prevention. In the context of dentistry, it commonly refers to the dental hygienist, a licensed practitioner who collaborates with dentists to provide preventive oral care and patient education.

In dental practice, the hygienist conducts preventive treatments and supports diagnostic processes. Typical duties include removing plaque and calculus, performing dental cleanings, applying fluoride and sealants, taking and developing radiographs as allowed, and assessing the patient’s oral health status. They educate patients on proper brushing and flossing techniques, discuss nutrition and tobacco cessation, and help develop strategies to prevent dental diseases. While they perform many routine and preventive procedures, they do not diagnose conditions or perform invasive dental treatments; diagnosis and major treatment planning are the responsibility of the dentist, with the hygienist acting under applicable supervision and regulation.

Education and licensure requirements vary by country and region. Most jurisdictions require completion of an accredited dental hygiene program, which can be an associate or bachelor’s degree, followed by licensure through national or regional examinations. Many places also require ongoing continuing education to maintain the license.

Practice settings include private dental offices, community health centers, hospitals, schools, and public health programs. The role of hygienists is central to preventive care and early intervention, contributing to overall oral health and, increasingly, to broader health outcomes through multidisciplinary preventive strategies. The exact scope of practice and supervision requirements differ by jurisdiction.
