Dentistry Chapter 37 Flashcards

Questions and Answers

Discuss the importance of pain control in dentistry.

It has allowed the dental profession to extend oral healthcare to millions of individuals who would otherwise remain untreated.

Describe the chemical makeup and application of topical anesthetic agents.

It is available in the form of ointments, liquids, sprays, and patches, with each form having a slightly different application process. Ointment should remain on site of injection for a minimum of 15 to 30 seconds, with a maximum of 1-2 minutes.

Discuss the chemical makeup and application of local anesthetic agents.

Injecting anesthetic solution near the nerve, where treatment is to take place. Cartridges are supplied in glass carpules, they have a rubber or silicone stopper at one end and an aluminum cap.

Describe nitrous oxide/oxygen (N2O/O2) sedation, and explain its use in dentistry.

Inhalation sedation may be the safest type of sedation used in dentistry. It produces stage 1 anesthesia/analgesia by using a combination of N2O and O2 gases. The patient inhales gases through a nose piece and feels the effect. Signup and view all the answers

Discuss the importance of reducing the dental team's exposure to N2O/O2.

A scavenger system is used to reduce the amount of N2O that escapes into the atmosphere, which is then inhaled. Signup and view all the answers

Discuss intravenous sedation and its use in dentistry.

It results in a minimally depressed level of consciousness. The patient maintains the ability to keep their airway open and respond to physical and verbal stimulation. Signup and view all the answers

Discuss general anesthesia and its use in dentistry.

Antianxiety agents are administered, resulting in the loss of protective reflexes and the ability to maintain airway independently. This is referred to as Stage III. Signup and view all the answers

Study Notes

Importance of Pain Control in Dentistry

Enhances access to oral healthcare for millions, preventing untreated dental issues.
Crucial for patient comfort and compliance during dental procedures.

Topical Anesthetic Agents

Available in multiple forms: ointments, liquids, sprays, patches.
Application varies; ointments should remain on the injection site for at least 15-30 seconds, up to a maximum of 1-2 minutes for effectiveness.

Local Anesthetic Agents

Administered by injection near the nerve relevant to the treatment site.
Typically housed in glass carpules with a rubber or silicone stopper and an aluminum cap for protection and ease of use.

Nitrous Oxide/Oxygen (N2O/O2) Sedation

Considered the safest inhalation sedation method in dentistry.
Induces stage 1 anesthesia/analgesia using a mix of N2O and O2.
Administered via a nosepiece, allowing patients to feel the effects quickly.

Reducing Exposure to N2O/O2

Implementation of a scavenger system to minimize N2O escape into the atmosphere.
Protects dental team members from potential health risks associated with inhalation of nitrous oxide.

Intravenous Sedation

Achieves a minimally depressed level of consciousness.
Patients retain the ability to maintain an open airway and respond to stimuli, ensuring safety during procedures.

General Anesthesia

Involves administration of antianxiety agents, leading to loss of protective reflexes.
Patients are unable to maintain airway control independently, typically utilized for more invasive procedures.
