“ Recognizing state power as to such matters, appellant insists that the statute in question goes too far because it prohibits advertising of the described character, although it may be truthful.

“ Plaintiff is not entitled to complain of interference with the contracts he describes, if the regulation of his conduct as a dentist is not an unreasonable exercise of the protective power of the state. ”

“ Nor has plaintiff any ground for objection because the particular regulation is limited to dentists and is not extended to other professional classes. The state was not bound to deal alike with all these classes, or to strike at all evils at the same time or in the same way.
