| Question | Answer |
|---|---|
| Reduces pain? | Anesthetics. |
| Relieves anxiety? | Sedation. |
| Administered directly into bloodstream, patient may be conscious, but in deeply relaxed state, patient has no memory of events taking place while sedated? | IV sedation. |
| Patient can still communicate? | conscious sedation. |
| May make patient calm and drowsy or calm and relaxed? | Oral sedation. |
| Used commonly as a sedative hypnotic, calm and drowsy and as a anti anxiety, calm and relaxed? | Benzodiazepine. |
| Calm and drowsy? | Sedative hypnotic. |
| Calm and relaxed? | Anti anxiety. |
| Administered through face mask, laryngeal airway or endotraycylur tube? | Inhalation sedation. |
| Creates unconscious state, must be carefully controlled, feeling and sensation lost? | General anesthesia. |
| Produces deadened or pain free area, sensory impulses temporarily blocked, affects nerve fibers carrying messages to brain? | Local anesthesia. |
| Injection into muscle of upper arm or thigh, takes 20 to 30 minutes to take effect? | Intramuscular sedation. |
| Numbs particular area, used prior to local anesthetic, desensitizes oral mucosa? | Topical anesthesia. |
| Has 5-10% anesthetic solution? | Topical anesthesia. |
| consist of 2% anesthetic solution? | Local anesthesia. |
| Used for root planning, periodontal probing, preparing for local sedation, repressing gag reflex? | Topical anesthesia. |
| Hypersensitive reaction, can occur up to 24 hours after application? | Allergic reaction. |
| Should remain on mucosa tissue for 1 minute? | Topical anesthesia. |
| Can be short(30 min), intermediate(60 min), or long(90 min) in duration. | Local anesthesia. |
| Constricts blood vessel in turn controls bleeding at site being worked on? | Vasoconstrictors. |
| Most common vasoconstrictor? | Epinephrine. |
| More likely to cause an allergic reaction, Novocain, procaine? | Ester. |
| More common-lower incidence of allergic reaction, lidocaine mepivacaine? | Amides. |
| Patient may be allergic to one but not the other? | Ester/Amides. |
| Drugs that can be added to the solution to make the duration time longer? | Vasoconstrictors. |
| A state of calmness or the process of reducing nervous excitement? | Sedation. |
| Injection near small terminal nerve branches, numbs tissue surrounding a tooth, takes 1-2 minutes to take effect? | Local infiltration. |
| Injection near large terminal nerve branches, used on most procedures on maxillary arch and the mandibular incisors? | Field block/ infiltration. |
| Absorbs well due to cancellous bone? | Local infiltration. |
| Numbs one or two teeth? | Local infiltration. |
| Injection site near apex of tooth being worked on, patient will feel numb within 2-3 minutes? | Local infiltration. |
| Injection near main trunk nerve, eliminates sensations over a large area? | Nerve block. |
| Numbs an entire quadrant, used on the mandibular, takes 4-5 minutes to take effect? | Nerve block. |
| Behind and lingual to retromolar area? | Mandibular block or inferior alveolar nerve block. |
| Between the apices of premolars? | Mental block. |
| Most common ADA recommended, allows operator to verify that they have not penetrated a blood vessel? | Aspirating syringe. |
| Short, 1 inch, Long, 1-5/8( 1.625)? | Needle. |
| Internal opening of the needle? | Lumen. |
| Protects patient if glass breaks contains manufacturers info? | Label. |
| Standardized system, ADA requires it? | Color coded. |
| Anesthetizes the following, bone, soft tissue, root, teeth, single or multiple teeth? | Intraosseous anesthesia. |
| Requires a special system for administration, A perforator, an 8mm 27-gauge needle, known as a stabident system? | Intraosseous injection. |
| Inserting needle into the long axis of tooth? | Intraligimentary injection also called periodontal ligament injection. |
| Delivered directly into nerve chamber, root canal therapy, severe abscess, directly in to pulp canal? | Intrapulpal injection. |
| Pain free injections? | Computer-controlled local anesthesia delivery system. |
| Blocked nasal passage, first trimester of pregnancy, risk of bone marrow suppression, in-vitro fertilization procedures, neurological complaints? | Contradictions of nitrous oxide. |
| Blue tank? | Nitrous oxide. |
| Green tank? | Oxygen. |
| Breathe oxygen for a minimum of five minutes or until signs of the nitrous oxide have dissipated? | Recovery. |
| Symptoms due to an overdose of anesthetic solution? | Toxic reaction. |
| Local anesthetics used for injections are available in what form? | Liquid. |
| What is one of the most common vasoconstrictor ratios? | 1: 100,000. |
| What is the sensation of feeling numb/ Can be a complication? | Paresthesia. |
| Holds cartridge/ carpule? | Barrel. |
| Rod with harpoon end of it? | Piston rod. |
| Needle attaches to syringe? | Threaded end. |
| Barbed tip of piston rod, can get dulled? | Harpoon. |
| Uses long needle? | Infraorbital. |
| Length of needle from barb to tip of bevel? | Shank. |
| Adjust the gas flow through the unit? | Flow meter. |
| Infiltration injection effects? | Individual teeth. |
| Middle superior alveolar injection effects? | Maxillary premolars in one quadrant. |
| Inferior alveolar nerve injection effects? | A mandibular quadrant. |
| Mental nerve block injection effects? | Mandibular premolars, canines. |
