4.2 Expanded Functions: Coronal Polishing & Pit and Fissure Sealants

4.2 Coronal Polishing and Sealants

Two functions, two qualification sets

Texas treats coronal polishing and pit-and-fissure sealant placement as separate delegated assistant functions. A worker qualified for one is not automatically qualified for the other. The dentist must verify the assistant’s documentation before delegation and use the supervision required by Rule 114.5 and related provisions.

Coronal polishing

An assistant may perform coronal polishing under direct supervision after satisfying one of the current education pathways. The assistant may have completed the relevant training in a CODA-accredited dental assisting program, or may qualify through a Board-compliant course of at least eight hours together with at least one year of dental-assisting experience. Do not use the obsolete claim that every applicant needs two years or 4,000 hours for coronal polishing.

The procedure is limited to removing plaque and extrinsic stain from exposed tooth surfaces with the permitted technique. It is not scaling, root planing, diagnosis, or a comprehensive prophylaxis. The service may not be billed or represented as an oral prophylaxis. If calculus or a condition requiring diagnosis is present, the dentist or hygienist addresses it within that professional’s scope.

The dentist remains in the facility, authorizes the service, and evaluates the patient as required. Course completion does not support independent services at a salon, school, or community event.

Pit-and-fissure sealants

Sealant placement has a higher experience threshold. The assistant must have at least two years of dental-assisting experience, maintain current BLS, and complete at least eight hours of didactic and clinical education in sealant placement through a qualifying course. The dentist determines that each surface is appropriate for a sealant and delegates the procedure under the required direct supervision.

Permitted preparation is limited. Qualification to place sealants does not authorize the assistant to remove caries, prepare a cavity, alter enamel with a bur, diagnose questionable lesions, or perform a prophylaxis. The assistant follows the dentist’s selection and the trained isolation, etching, placement, curing, and evaluation workflow.

Dentist verification rather than old certificates

Older resources may direct an assistant to obtain a separate TSBDE “coronal polishing certificate” or “sealant certificate.” Current Board guidance instead places verification responsibility on the delegating dentist. The practice should retain course certificates, evidence of experience, BLS documentation where required, and the assistant’s RDA information if applicable.

This does not make education informal. A dentist who simply states “I trained the assistant myself” must still show that the rule’s education route was satisfied.

Documentation and infection control

The chart should identify the teeth or surfaces treated, material used when clinically important, assistant who performed the task, dentist authorization and evaluation, and any inability to complete isolation or curing. Standard precautions, manufacturer instructions, and eye and airway protection apply. A contaminated surface should be re-isolated or handled according to product and infection-control requirements rather than covered to meet a production target.

Applied examples

An assistant with 14 months of experience and a compliant eight-hour course may be considered for delegated coronal polishing under direct supervision. The same facts do not satisfy the two-year sealant threshold. A CODA graduate with included polish training may use that route, but CODA graduation alone does not erase the sealant experience and training rules. An office may charge for the dentist’s overall visit, but it may not falsely code the assistant’s polish as a completed prophylaxis.

Evaluating the result

For polishing, evaluate tissue condition, stain and deposit limits, abrasiveness, isolation, and patient tolerance. Stop if the procedure would damage exposed dentin, sensitive tissue, or a restoration. For sealants, the dentist’s tooth selection should account for eruption, caries risk, suspected cavitation, isolation, and restorative need. The assistant checks retention and obvious excess within the delegated protocol, while the dentist performs the required evaluation.

At recall, loss of a sealant is a clinical finding, not proof of misconduct. Document the surface, repair or replacement plan, and any developing disease. Quality tracking can identify isolation, curing-light, material, or training problems without converting the assistant into the diagnostician.
