Summary
Computer-controlled dental anesthetic delivery systems were compared to traditional methods. Both dentists and patients found the computer-controlled system and traditional injections equally acceptable for dental anesthesia.
Area of Science:
- Dentistry
- Anesthesiology
- Medical Devices
Background:
- Traditional dental anesthetic delivery can cause patient anxiety.
- Advancements in technology offer potential improvements in patient comfort and procedure standardization.
Purpose of the Study:
- To evaluate and compare a computer-controlled dental anesthetic delivery system against the traditional method.
- To assess patient and dentist acceptance of both anesthetic delivery systems.
Main Methods:
- Trained dentists utilized both computer-controlled and traditional anesthetic delivery systems during routine patient care.
- Dentists and patients completed surveys assessing their experience with each injection method.
Main Results:
- Statistical analysis indicated similar ratings for both computer-controlled and traditional anesthetic delivery methods.
- Both patients and dentists reported comparable experiences with the two systems.
Conclusions:
- Computer-controlled dental anesthetic injections are accepted equally well by patients and dentists compared to traditional methods.
- The study suggests comparable patient and professional acceptance for innovative versus conventional anesthetic delivery techniques.

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...
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...

01:30Local 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...
01:29Local 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...
