A dental surgeon or dental surgery student who has been a replacement or assistant to a dental surgeon for a period of more than three consecutive months must not practise before the expiry of a period of two years in a position where he or she may enter into competition with that dental surgeon, subject to agreement between the contracting parties or, failing that, authorisation from the Conseil Départemental de l’Ordre given on the basis of public health needs.
Any clause intended to impose such a prohibition when the replacement or assistantship is for less than three months would be contrary to professional ethics.
