PERMANENT RULES

DEPARTMENT OF HEALTH


(Dental Quality Assurance Commission)

[ Filed June 19, 2008, 3:55 p.m. , effective July 1, 2008 ]


Effective Date of Rule: July 1, 2008.

Other Findings Required by Other Provisions of Law as Precondition to Adoption or Effectiveness of Rule: RCW 34.05.380 (3)(a) such action is required by the state or federal constitution, a statute, or court order. Action is required by chapter 269, Laws of 2007 (SHB 1099).

Purpose: Amending and adding new sections to chapter 246-817 WAC, Credentialing and scope of practice requirements for dental assistants and expanded function dental auxiliaries. The adopted rules provide clear registration requirements for dental assistants and licensing requirements for expanded function dental auxiliaries (EFDAs). Adopted changes and new sections also provide detailed scope of practice for dental assistants and EFDAs.

Citation of Existing Rules Affected by this Order: Amending WAC 246-817-210, 246-817-510, 246-817-520 and 246-817-540; and new sections WAC 246-817-190, 246-817-195, 246-817-200, 246-817-525, and 246-817-545.

Statutory Authority for Adoption: RCW 18.260.120 and 18.32.0365.

Adopted under notice filed as WSR 08-07-099 on March 19, 2008.

Changes Other than Editing from Proposed to Adopted Version: The dental quality assurance commission adopted the rules with the following changes that are nonsubstantive and only clarify the rules:

1. WAC 246-817-510(2) Coronal polishing, removed language that named type of instrument to be used. This change creates a general definition and allows for changes in technology.

2. WAC 246-817-520(30), changed the term anxiolysis to minimal sedation. The change is consistent with other rule language in chapter 246-817 WAC.

3. WAC 246-817-520 (38), (39), (40), combined these three acts into one item subsection (38) and added temporary oral devices to further clarify the three acts. The term night guard was changed to occlusal guard. Occlusal is consistent with other rule language in chapter 246-817 WAC.

4. WAC 246-817-525 [(1)](w), changed the term anxiolysis to minimal sedation. The change is consistent with other rule language in chapter 246-817 WAC.

5. WAC 246-817-525 [(1)](ff), (gg), (hh), combined these three acts into one item subsection (ff) and added temporary oral devices to further clarify the three acts. The term night guard was changed to occlusal guard. Occlusal is consistent with other rule language in chapter 246-817 WAC.

6. WAC 246-817-540(20), the act of using a laser was clarified to meet dental practice needs. The original language was modeled after the medical practice act.

7. WAC 246-817-540(21), removed air polishing from this act. Air polishing is a different act than air abrasion and should not have been included in this act.

8. WAC 246-817-540(22), changed capping to caps. This is a grammatical correction.

9. WAC 246-817-540(23), changed night guards to occlusal guards. Occlusal is consistent with other rule language in chapter 246-817 WAC.

10. WAC 246-817-545(18), the act of using a laser was clarified to meet dental practice needs. The original language was modeled after the medical practice act.

11. WAC 246-817-545(19), removed air polishing from this act. Air polishing is a different act than air abrasion and should not have been included in this act.

12. WAC 246-817-545(20), changed capping to caps. This is a grammatical correction.

13. WAC 246-817-545(21), changed night guards to occlusal guards. Occlusal is consistent with other rule language in chapter 246-817 WAC.

14. WAC 246-817-190 and 246-817-195, both reference WAC 246-817-990 for applicable fees. The correct fee number is WAC 246-817-99005. The administrative change was made to both WAC 246-817-190 and 246-817-195.

WAC 246-817-510   Definitions for WAC 246-817-501 through 246-817-570.   (1) "Close supervision" means that a licensed dentist whose patient is being treated has personally diagnosed the condition to be treated and has personally authorized the procedures to be performed. A dentist shall be physically present in the treatment facility while the procedures are performed. Close supervision does not require a dentist to be physically present in the operatory; however, an attending dentist must be in the treatment facility and be capable of responding immediately in the event of an emergency.

(2) "Coronal polishing" means a procedure limited to the removal of plaque and stain from exposed tooth surfaces, utilizing an appropriate ((rotary)) instrument ((with rubber cap or brush)) and ((a)) polishing agent.

This procedure shall not be intended or interpreted as an oral prophylaxis as defined in WAC 246-817-510 a procedure specifically reserved to performance by a licensed dentist or dental hygienist. Coronal polishing may, however, be performed by dental assistants under close supervision as a portion of the oral prophylaxis. In all instances, however, a licensed dentist shall determine that the teeth need to be polished and are free of calculus or other extraneous material prior to performance of coronal polishing by a dental assistant.

(3) "Debridement at the periodontal surgical site" means curettage ((and/))or root planing after reflection of a flap by the supervising dentist. This does not include cutting of osseous tissues.

(6) "Incising" is defined as part of the surgical procedure of which the end result is removal of oral tissue. Incising, or the making of an incision, is not a separate and distinct procedure in and of itself.

(7) "Luxation" is defined as an integral part of the surgical procedure of which the end result is extraction of a tooth. Luxation is not a distinct procedure in and of itself. It is the dislocation or displacement of a tooth or of the temporomandibular articulation.

(8) "Oral prophylaxis" means the preventive dental procedure of scaling and polishing which includes complete removal of calculus, soft deposits, plaque, stains and the smoothing of unattached tooth surfaces. The objective of this treatment shall be creation of an environment in which hard and soft tissues can be maintained in good health by the patient.

(9) "Periodontal soft tissue curettage" means the closed removal of tissue lining the periodontal pocket, not involving the reflection of a flap.

(10) "Root planing" means the process of instrumentation by which the unattached surfaces of the root are made smooth by the removal of calculus ((and/))or deposits.

(11) "Supportive services" means services that are related to clinical functions in direct relationship to treating a patient.

(12) "Suturing" is defined as the readaption of soft tissue by use of stitches as a phase of an oral surgery procedure. Suturing is not a separate and distinct procedure in and of itself.

(13) "Treatment facility" means a dental office or connecting suite of offices, dental clinic, room or area with equipment to provide dental treatment, or the immediately adjacent rooms or areas. A treatment facility does not extend to any other area of a building in which the treatment facility is located.
