infiltraatioanesteesia

Infiltraatioanestesia is a local anesthetic technique used in dentistry and medicine to numb a specific area of the body by injecting anesthetic solution directly into the soft tissues. This method is commonly employed for procedures affecting superficial structures or when a more targeted anesthetic effect is desired. The anesthetic solution is deposited into the connective tissue, allowing it to diffuse and block nerve impulses in the vicinity.

The administration involves a fine needle injecting a small volume of local anesthetic, such as lidocaine or articaine, into the submucosa or periosteum. The diffusion of the anesthetic agent then prevents the transmission of pain signals from the treated area to the brain. This technique is particularly useful for procedures like simple tooth extractions, fillings on the facial or buccal surfaces of teeth, and minor surgical interventions on the skin or oral mucosa.

Compared to other local anesthetic techniques, infiltration anesthesia is relatively simple to perform and carries a lower risk of systemic complications or nerve injury, provided proper technique is used. The onset of numbness is typically rapid, and the duration depends on the type and concentration of the anesthetic agent used, as well as the presence of vasoconstrictors. Patient comfort and compliance are generally good with this method.
