In radio advertisements, the required statement shall be articulated so as to be clearly audible and understandable by the radio audience. In television advertisements, the required statement shall be either clearly audible and understandable to the television audience, or displayed in a written form that remains clearly visible for at least five seconds to the television audience. This subdivision shall be operative on and after July 1, 1994. (b) The Dental Board of California may adopt regulations necessary to enforce and administer this section. (c) The Dental Board of California may suspend or revoke the registration of any service that fails to comply with paragraph (9) of subdivision (a). No service may reregister with the board if it has a registration that is currently under suspension for a violation of paragraph (9) of subdivision (a), nor may a service reregister with the board if it had a registration revoked by the board for a violation of paragraph (9) of subdivision (a) less than one year after that revocation.(d) The Dental Board of California may petition the superior court of any county for the issuance of an injunction restraining any conduct that constitutes a violation of this section.(e) It is unlawful and shall constitute a misdemeanor for a person to operate a group advertising and referral service for dentists without providing its name and address to the Dental Board of California.(f) It is the intent of the Legislature in enacting this section not to otherwise affect the prohibitions provided in Section 650.

(g) This section shall not be construed to authorize a referral service to engage in the practice of dentistry.(Amended by Stats. 2015, Ch. 426, Sec. 4. (SB 800) Effective January 1, 2016.)
