This is not sufficient if ssh is using PAM for authentication (because
PAM will allow root logins).  Make sure you also have disabled PAM
authentication with

ChallengeResponseAuthentication    no

I think both of these settings default to "no" these days, but you
might want to check your config to be sure.
