Pain And Anxiety Management Flashcards
What 2 groups can local anesthesia be broken down into?
Esters and Amides
Esters
Higher incidence of allergic reaction
Shorter acting
Metabolized in the blood plasma
Amides
Low incidence of allergic reaction
Potential for toxicity & overdose
Metabolized in the liver
Causes vasodilation of local blood vessels
What are reasons to use vasoconstrictors?
Safety – potential for toxic reaction
Longevity- duration is increased
Effectiveness- depth and profoundness is increased
Hemostasis- decreased
Types of vasoconstrictors
Epinephrine- used in concentrations of 1:1000,000 and 1:200,000
Levonordefrin- Half as potent as Epinephrine and may have a less cardiac effect
Risks of using vasoconstrictors
Hypersensitivity to drug Medically compromised Heart disease Stroke Recent heart surgery
Other names for lidocaine (amide)
Xylocaine, octocaine, lignospan
What is the first amide and still most widely used dental anesthetic that is also available as a topical?
Lidocaine
Used with vasoconstrictor (epinephrine)
What are indications for local anesthesia?
Any treatment that may cause the patient pain: scaling and root cleaning, excessive instrumentation, challenging areas like pockets and furcation, sensitive route surfaces, inflamed tissues and excessive bleeding
Also for application of crowns, bridges, Endo, surgeries etc.
Armamentarium needed for local anesthesia
Syringe Needle Topical Gauze Anesthetic Needle guard or recapping device
Describe the type of syringe that should be used
Should be an aspirating syringe
Made of metal or plastic that can be sterilized
Single use syringes can also be used
What are the different needle lengths?
Long- 1.5”/32-40mm
Short- 1”/20-25mm
Ultra short- 1/2”/10-12mm
What gauge needles do we use?
25, 27 and 30
The smaller the number the larger in size and stiffer= less breakage, more accurate and easier aspiration
Describe the cartridge or Carpule used
Made of glass that holds anesthetic. 1.7 to 1.8 mL
Labeled with type of anesthetic, manufacture and expiration date
Pre-sterilized, color-coded and disposable
Storage of anesthetic carpule
Store in a cool place away from light and it’s own container. Never in alcohol or any liquid solution
Do not use carpule if:
Cloudy, broken, bubble to large or small, expired, extruded stopped, rusted/corroded or rusted top
Major groups of topical anesthetic’s
Esters and amides
Esters used as topicals
Benzocaine, ethyl aminobenzoate (Hurricaine, cetacaine)
Amides used as topicals
Lidocaine and lidocaine hydrochloride
How are topicals supplied?
As liquid, gel, ointment, spray and patch
How long is the onset of effects from a patch?
2 to 5 minutes and full affect us after 15 minutes and duration is approximately 45 minutes
How long is the onset for most topical esters?
Most answer is 30 seconds and reaches full affect after a few minutes and duration is approximately 10 minutes
How long is the onset for topical amides?
I said is 1 to 2 minutes in full affect me take five minutes in duration is approximately 15 minutes
What should you do before the application of topical anesthetic?
Consult medical history
Determine agent to be used
Explain purpose and effect to the patient
Dry the area
Apply with cotton tipped swab
After application, wipe area and rinse
What are the four main types of pain management?
Topical (benzocaine, lidocaine, citanest (liquid), dentapatch, oraquix (injectable))
Drugs- codeine, Valium
General anesthesia- intravenous sedation
Nitrous oxide gas
Basic injections in the maxillary arch
ASA MSA PSA Infraorbital (IO) Greater Palatine (GP) Nasopalatine (NP) Infiltration
What area does an ASA injection target? Where is the topical placed?
Canine and incisors and supporting structures
Topical placed at the Apex of the canine
What does the MSA injection target? Where is the topical placed?
Middle superior alveolar- first and second pre-molars, Mesiobuccal root of first molar and supporting structures
Topical placed at the Apex of the maxillary second premolar
What does the PSA injection target? Where is the topical placed?
Posterior superior alveolar- Second third and first molar excluding mesiobuccal root and supporting structures
Topical placed at the Apex of the maxillary second molar
What does the infraorbital injection target? Where is the topical placed?
Premolars, canine, incisors and supporting structures. Includes ASA and MSA
Topical placed at the Apex of the maxillary first premolar
What does the greater Palatine injection target? Where is the topical placed?
No hard tissues, soft tissues- palatal tissues from teeth to midline from distal of the third molar to the canine
Topical placed just distal to the first molar
What does the nasopalatine injection target?
No hard tissues, palatal tissues from left canine to right canine
Topical placed at the incisive papilla
What does and infiltration injection target? Where is the topical placed?
Teeth associated with the area
Topical placed at mucobuccal fold of tooth to be injected
What are the different mandibular injections?
Long buccal
Inferior alveolar with lingual (mandibular block) (IAMB)
Gow-Gates techniques
Akinosi
Mental and incisive
What does the long buccal injection target? Where is the topical placed?
No hard tissue and facial of molars
Topical placed distal to the third molar
What does the inferior alveolar with lingual injection target?
Molars, premolars, canine and incisors to midline as well as supporting structures
Topical is placed in the retromolar area
How to place an inferior alveolar nerve block
Retract the lip
Placed thumb on anterior surface of the ramus
Approach from the opposite pre-molars
What does the lingual injection target? Where is the topical placed?
No hard tissue and all of the lingual gingival to midline, 2/3 of the tongue and floor of the mouth

Topical placed in the retromolar area
What does the show-Gates technique target?
Hard tissue- mandibular teeth to midline, body of mandible and inferior portion of ramus and soft tissue is facial and lingual, anterior 2/3 of tongue, floor of the mouth, posterior area of cheek and temporal regions
