Summary
Buccal nerve blocks provide anesthesia for dental surgery. This study found that the anesthesia often extends further anteriorly than expected, reaching the incisors in some patients, which is useful for lower anterior surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Anesthesia
- Local Anesthesia Techniques
Background:
- Buccal nerve block is a common procedure in dentistry.
- Understanding the precise spread of anesthesia is crucial for effective pain management.
- Limited data exists on the full extent of buccal nerve anesthesia in the anterior buccal mucosa.
Purpose of the Study:
- To determine the complete anesthetic spread of the buccal nerve block.
- To evaluate the efficacy of buccal nerve block for anterior mandibular procedures.
- To provide data for optimizing anesthetic techniques in dental surgery.
Main Methods:
- A prospective study involving 40 healthy Thai patients undergoing dental surgery.
- Buccal nerve block was administered, followed by exploration of the buccal mucosa with a sharp probe to map anesthesia.
- Inferior alveolar and lingual nerve blocks were also performed prior to surgery.
Main Results:
- Anesthesia primarily extended from the retromolar area to the second molar.
- A significant finding was that anesthesia in some patients extended to the first premolar and central incisor.
- The anterior extent of anesthesia varied among participants, with some showing coverage to the anterior region of the same quadrant.
Conclusions:
- Buccal nerve block can provide anesthesia extending to the anterior buccal mucosa, including the incisor region in some individuals.
- This extended anesthetic effect offers a valuable option for lower anterior dental surgery.
- The findings suggest that buccal nerve block can be a reliable technique for procedures involving the anterior mandibular teeth.

01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
01:23Local Anesthetics: Common Agents and Their Applications
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
