The following definitions and abbreviations and those found in chapter 182-500 WAC apply to this chapter. The medicaid agency also uses dental definitions found in the American Dental Association's Current Dental Terminology (CDT) and the American Medical Association's Physician's Current Procedural Terminology (CPT). Where there is any discrepancy between the CDT or CPT and this section, this section prevails. (CPT is a trademark of the American Medical Association.)

"American Dental Association (ADA)" is a national organization for dental professionals and dental societies.

"Anterior" refers to teeth (maxillary and mandibular incisors and canines) and tissue in the front of the mouth. Permanent maxillary anterior teeth include teeth six, seven, eight, nine, ten, and eleven. Permanent mandibular anterior teeth include teeth twenty-two, twenty-three, twenty-four, twenty-five, twenty-six, and twenty-seven. Primary maxillary anterior teeth include teeth C, D, E, F, G, and H. Primary mandibular anterior teeth include teeth M, N, O, P, Q, and R.

"Asynchronous" means two or more events not happening at the same time.

"Behavior management" means using one additional professional staff, who is employed by the dental provider or clinic and who is not delivering dental treatment to the client, to manage the client's behavior to facilitate dental treatment delivery.

"By-report" means a method of reimbursement in which the department determines the amount it will pay for a service when the rate for that service is not included in the agency's published fee schedules. Upon request the provider must submit a "report" that describes the nature, extent, time, effort and/or equipment necessary to deliver the service.

"Caries" means carious lesions or tooth decay through the enamel or decay on the root surface.

• "Incipient caries" means the beginning stages of caries or decay, or subsurface demineralization.

• "Rampant caries" means a sudden onset of widespread caries that affects most of the teeth and penetrates quickly to the dental pulp.

"Comprehensive oral evaluation" means a thorough evaluation and documentation of a client's dental and medical history to include extra-oral and intra-oral hard and soft tissues, dental caries, missing or unerupted teeth, restorations, occlusal relationships, periodontal conditions (including periodontal charting), hard and soft tissue anomalies, and oral cancer screening.

"Conscious sedation" means a drug-induced depression of consciousness during which a client responds purposefully to verbal commands, either alone or accompanied by light tactile stimulation. No interventions are required to maintain a patent airway, spontaneous ventilation is adequate, and cardiovascular function is maintained.

"Core buildup" means the building up of clinical crowns, including pins.

"Coronal" means the portion of a tooth that is covered by enamel.

"Crown" means a restoration covering or replacing the whole clinical crown of a tooth.

"Current dental terminology (CDT)" means a systematic listing of descriptive terms and identifying codes for reporting dental services and procedures performed by dental practitioners. CDT is published by the Council on Dental Benefit Programs of the American Dental Association (ADA).

"Current procedural terminology (CPT)" means a systematic listing of descriptive terms and identifying codes for reporting medical services, procedures, and interventions performed by physicians and other practitioners who provide physician-related services. CPT is copyrighted and published annually by the American Medical Association (AMA).

"Decay" means a term for caries or carious lesions and means decomposition of tooth structure.

"Deep sedation" means a drug-induced depression of consciousness during which a client cannot be easily aroused, ventilatory function may be impaired, but the client responds to repeated or painful stimulation.

"Dental general anesthesia" see "general anesthesia."

"Dentures" means an artificial replacement for natural teeth and adjacent tissues, and includes complete dentures, immediate dentures, overdentures, and partial dentures.

"Denturist" means a person licensed under chapter 18.30 RCW to make, construct, alter, reproduce, or repair a denture.

"Distant site (location of dental provider)" means the physical location of the dentist or authorized dental provider providing the dental service to a client through teledentistry.

"Edentulous" means lacking teeth.

"Endodontic" means the etiology, diagnosis, prevention and treatment of diseases and injuries of the pulp and associated periradicular conditions.

"EPSDT" means the agency's early and periodic screening, diagnostic, and treatment program for clients age twenty and younger as described in chapter 182-534 WAC.

"Extraction" see "simple extraction" and "surgical extraction."

"Flowable composite" means a diluted low-viscosity-filled resin-based composite dental restorative material that is used in cervical restorations and small, low stress bearing occlusal restorations.

"Fluoride varnish, rinse, foam or gel" means a substance containing dental fluoride which is applied to teeth, not including silver diamine fluoride.

"General anesthesia" means a drug-induced loss of consciousness during which a client is not arousable even by painful stimulation. The ability to independently maintain ventilatory function is often impaired. Clients may require assistance in maintaining a patent airway, and positive pressure ventilation may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function. Cardiovascular function may be impaired.

"Interim therapeutic restoration (ITR)" means the placement of an adhesive restorative material following caries debridement by hand or other method for the management of early childhood caries. It is not considered a definitive restoration.

"Limited oral evaluation" means an evaluation limited to a specific oral health condition or problem. Typically a client receiving this type of evaluation has a dental emergency, such as trauma or acute infection.

"Limited visual oral assessment" means an assessment by a dentist or dental hygienist provided in a setting other than a dental office or dental clinic to identify signs of disease and the potential need for referral for diagnosis.

"Medically necessary" see WAC 182-500-0070.

"Oral evaluation" see "comprehensive oral evaluation."

"Partials" or "partial dentures" mean a removable prosthetic appliance that replaces missing teeth on either arch.

"Periodic oral evaluation" means an evaluation performed on a patient of record to determine any changes in the client's dental or medical status since a previous comprehensive or periodic evaluation.
