     "Anterior" means teeth and tissue in the front of the mouth.

     (1) "Mandibular anterior teeth" - incisors and canines: Permanent teeth twenty-two, twenty-three, twenty-four, twenty-five, twenty-six, and twenty-seven; and primary teeth M, N, O, P, Q, and R.

     "Behavior management" means using the assistance of one additional dental professional staff to manage the behavior of a developmentally disabled client or a client age eighteen or younger to facilitate the delivery of dental treatment.

     "By report" - a method of reimbursement in which MAA determines the amount it will pay for a service when the rate for that service is not included in MAA'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 tooth decay through the enamel or decay of the root surface.

     "Child" for the general purposes of the medical assistance administration's (MAA) dental program, means a client twenty years of age or younger. (MAA's payment structure changes at age nineteen, which affects specific program services provided to children or adults.)

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.
