ADA policies on licensure encourage states to ease mobility restrictions while maintaining sufficient control to ensure that only qualified individuals provide dental treatment within the state. Many states have had provision to license by credentials for a long time. Licensure by credentials is rapidly replacing reciprocity as an alternate form of licensure. Only four states still participate in what can be termed purely reciprocal licensure agreements. In contrast, 21 states currently offer licensure by credentials. Another trend in licensure in recent years has been increased state participation in regional clinical examination services. Today, 32 states participate in four regional clinical examination services. With the increasing number of states offering licensure by credentials and participating in regional boards, the prospect for increased mobility for dentists appears good.
