Licensure, Registration, and Scope of Practice for Dental Hygienists
Licensure pathway
Massachusetts dental hygiene applicants must graduate from an accredited dental hygiene program, pass the National Board Dental Hygiene Examination, pass a Board-recognized clinical examination, and pass the Massachusetts jurisprudence examination. Applications are filed through DPL. Licensure is biennial; renewal requires continuing education, a fee, and compliance with reporting obligations.
Supervision and delegation
Direct supervision means the dentist is on the premises, has examined the patient, and is available. General supervision means the dentist has authorized the procedure for a patient of record but need not be present. Massachusetts also recognizes public health dental hygienists who may provide specified services in approved public health settings under 234 CMR. Core hygiene functions include prophylaxis, scaling and root planing, polishing, fluoride, sealants, and radiographs; local anesthesia requires the specific permit and supervision.
Worked example
A school asks a hygienist to place sealants with no dentist on site. Reasoning: sealants are a delegated hygiene function, but the setting must qualify as a public health setting, and the hygienist must hold the public health designation and follow the written requirements. If those conditions are not met, the hygienist needs at least general supervision.
Traps
General supervision is not independent practice. A hygienist may not diagnose, prescribe, or perform surgery. Do not assume an out-of-state clinical examination is automatically accepted; verify Board rules.
