What does the ASA anesthetize?
What does the ASA anesthetize?
The anterior superior alveolar (ASA) nerve block anesthetizes the maxillary canine, the central and lateral incisors, and the mucosa above these teeth, with occasional crossover to the contralateral maxillary incisors (see image below).
What does the PSA nerve block anesthetize?
Background: The posterior superior alveolar nerve (PSAN) block is a dental nerve block used for profound anesthesia of the maxillary molars.
What does MSA anesthetize?
The middle superior alveolar (MSA) injection will anesthetize the mesiobuccal aspect of the maxillary first molar, both premolars, PDL, buccal bone, and periosteum, along with the soft tissue lateral to this area13 (Figure 2).
What anesthesia is used for SRP?
Injected local anesthesia has been used to secure anesthesia for scaling and root planing (SRP) and continues to be the anesthetic of choice for pain control. Alternatively, intra-pocket anesthetic gel has been used as an anesthetic during SRP.
Where do you inject ASA?
Malamed states the ASA injection site is the mesiobuccal fold above the first premolar, as this is the landmark that provides the shortest path through the tissue to the IO foramen. Intraorally, this injection will look quite similar to the MSA, just one tooth forward.
What is Supraperiosteal injection?
Supraperiosteal injection (commonly known as local infiltration) is indicated whenever dental procedures are confined to a localized area in either the maxilla or mandible. The terminal endings of the nerves innervating the region are anesthetized.
What does the PSA injection numb?
The posterior superior alveolar (PSA) nerve block anesthetizes maxillary molar teeth (see image below). With the PSA nerve block, the first molar may not be completely anesthetized; in this case, the PSA nerve block can be used in conjunction with an MSA/supraperiosteal block.
What is MSA in dentistry?
The middle superior alveolar (MSA) nerve block anesthetizes the maxillary premolars with occasional overlap to the canine and first molar (see image below).
How do you anesthetize your teeth?
Hold the syringe parallel with the long axis of the tooth on the mesial or distal aspect. Insert the needle (bevel facing the root) to the depth of the gingival sulcus (Figure 10). Advance the needle until resistance is met. Then, administer a small amount of anesthetic (0.2 mL) slowly over the course of 20–30 seconds.
What kind of local anesthesia is used in dentistry?
Common local anesthetic drugs used in dentistry include lidocaine, articaine, prilocaine, mepivacaine, and bupivacaine. These drugs impart a numbing effect that lasts for 30 to 60 minutes.
Does SRP require anesthesia?
The deep cleaning of SRP can be painful and involves instrumentation in sensitive areas. Often patients have painful inflammation, especially where the pockets are particularly deep, that can be difficult to work around without anesthetic.
What is the MSA in dentistry?
The (MSA) Middle superior alveolar nerve block provides pulpal anesthesia to the maxillary premolars and mesial buccal root of the maxillary first molar and the supporting buccal soft tissue and bone. Lingual tissue is not anesthetized. It is located between the ASA and the PSA and is not present on all patients.
Where do you inject ASA in dentistry?
Injection Site. Malamed states the ASA injection site is the mesiobuccal fold above the first premolar, as this is the landmark that provides the shortest path through the tissue to the IO foramen. Intraorally, this injection will look quite similar to the MSA, just one tooth forward.
Why is the AMSA block important to dentistry?
Laura Webb, RDH, explains how the AMSA block is important to dentistry since it eliminates anesthesia to the soft tissues of the upper lip and face.
How safe is the ASA injection?
While the above should be taken into consideration, the ASA injection is a safe, simple anesthesia option that minimizes the number of injections and the volume of anesthetic deposited. The landmarks are easy for the clinician to locate, and the injection is comfortable for the patient.
