     "By report" - 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 department's published fee schedules. Upon request the provider must submit a "report" which 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 of the root surface.

     "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" is 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" refers to building up of clinical crowns, including pins.

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

     "Current procedural terminology (CPT)" is 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" is a term for caries or carious lesions and means decomposition of tooth structure.

     "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.

     "General anesthesia" is 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.

     "High noble metal" is a dental alloy containing at least sixty percent pure gold.

     "Limited oral evaluation" is 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.
