The pharmacology of local anesthesia is considered as the gate to dental
anesthesia techniques. In the biomedical field, the human should not be injected with
any medication unless the practitioner is well oriented about the nature of the medicine,
the mechanism of action, the recommended dose, the maximum allowed dose, and
possible complications. In this chapter, the techniques of local dental anesthesia have
been discussed in detail as well, including the anatomical landmarks and regional nerve
anatomy. The possible local and systemic complications have been added with the
proper way of management and percussions. The relation of common systemic diseases
to possible complications of local anesthesia medication has been discussed with
emphasis on some wrong practioner,s opinion regarding using of vasoconstrictors in
hypertensive patient (for details about management of medically compromised patients,
read chapter 5, page: 131-195).
