|December 29, 2009
Summary
New articaine formulations with epinephrine show good dental pulp anesthesia, though slightly less effective than traditional agents. Articaine without a vasoconstrictor demonstrated minimal analgesic effect.
Area of Science:
- Dentistry
- Pharmacology
- Anesthesiology
Background:
- Articaine is a widely used local anesthetic in dentistry.
- Epinephrine is often added to local anesthetics to prolong their duration and reduce bleeding.
- Optimizing articaine formulations is crucial for effective dental anesthesia.
Purpose of the Study:
- To evaluate the efficacy of different articaine preparations with varying epinephrine concentrations for dental pulp anesthesia.
- To compare the anesthetic activity of new articaine formulations against established agents.
Main Methods:
- Five articaine preparations were tested on 52 dental student volunteers.
- Formulations included 4% articaine with epinephrine (1:100,000, 1:200,000, 1:400,000), 2% articaine with epinephrine (1:200,000), and articaine without a vasoconstrictor.
- Anesthetic activity was assessed based on multiple criteria.
Main Results:
- New articaine-epinephrine combinations demonstrated significant dental pulp anesthesia.
- Their efficacy was comparable to classic anesthetic agents but slightly inferior across all studied criteria.
- Articaine without a vasoconstrictor exhibited negligible pulpal analgesia.
Conclusions:
- Articaine with epinephrine, in various concentrations, offers effective dental anesthesia.
- Further research may be needed to optimize formulations for enhanced efficacy.
- The inclusion of a vasoconstrictor is essential for achieving adequate pulpal analgesia with articaine.

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...

01:11Local 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...
01:29Local 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...

01:30Local 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...
01:24Parenteral Anesthetics: Overview
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
01:13Local Anesthetics: Pharmacokinetics
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...
