(1) Every dentist practicing within the area covered by any nonprofit dental service corporation shall have the right, on complying with such regulations as the corporation may make and with the approval of the state board of health, to register with such corporation for general or special dental service, as the case may be, within that area. Any nonprofit dental service corporation may, with the approval of the state board of health and the state board of dental examiners, remove from its register the name of any dentist, after due notice and hearing, for cause satisfactory to the corporation.

(2) A nonprofit dental service corporation shall impose no restrictions on the dentists who administer to its subscribers as to methods of diagnosis or treatment. The relation between a subscriber or any of his dependents and the dentist shall be identical with the relation that ordinarily exists in the community between such doctor and his patient. No person shall be permitted to interfere with a patient’s choice or selection of his dentist after that choice or selection has been made by an adult of sound mind; and any dentist shall have freedom of choice in registering for services with the corporation and may refuse to accept individual cases, so long as such refusal does not have the effect of an abrogation or revocation of any agreement existing between him and the corporation prior to its expiration.

(3) All matters, disputes, or controversies relating to the dental services rendered by the dentists or any questions involving professional ethics shall be considered, acted upon, disposed of, and determined by dentists, as selected in a manner prescribed in the bylaws of the nonprofit dental service corporations.
