31.—(1) Subject to subsection (2) of this section, any person who is registered in the register may, at any time after his first registration, apply in the form and manner determined by the Council to have a further qualification entered in the register in addition to his qualifications already entered therein.

(2) The Council shall determined the qualifications, not being qualifications required for the purpose of registration, which, on application by a person registered in the register in the manner determined by the Council and on payment of the appropriate fee, may be entered in the register as additional qualifications.

(3) Whenever, on an application by any registered dentist, the Council decides to enter in the register, pursuant to this section, any additional qualifications in respect of that dentist, the Council shall, as soon as may be after the registration is completed, send to that dentist a certificate stating that such additional qualifications have been entered in the register.
