One of the most important and challenging aspects of child behavior management is pain control. As a consequence of conflicting concerns—the dentist wanting to control pain with local anesthesia and the child fearing the pain of the needle—injection procedures present an almost constant challenge to the dentist's skills. Thus the aims of this chapter, which covers an important aspect of behavior management, are: (i) to discuss factors associated with administering injections; and (ii) to review the most commonly used local anesthetic techniques for children. The chapter focuses on the most commonly used injections, with an emphasis on how to administer local anesthesia with minimum pain and maximum effect. The techniques discussed are: basic injection technique, specific injection techniques and supplemental injection techniques. A brief discussion on the complications that can occur during local anesthesia is given at the end of the chapter.
