what is the criteria for an acceptable syringe for dental local anesthetics
Slide 3
1. Dental syringe must be durable and be able to withstand repeatable sterilization without being damaged
2. Must be able to accept cartridges and needles of different manufacturers
3. Permit repeated use
4. Inexpensive, light weight and simple to use
5. Aspirated blood should be visible in the cartridge ( barrel has open window )
Slide 4
What are the syringe types and classifications?
Slide 5
Give Characteristics of a cartridge? [5]
Slide 6
What are the contents of the cartridge? [5]
Slide 6
Functions of LA found in the cartridge?
Functions of Vasoconstrictor in the cartridge and give examples ?
Functions of preservatives in the cartridge and give examples?
Functions of sodium chloride in the cartridge?
Functions of distilled water in the cartridge?
What are the recommendations for use of cartridge? [5]
Slide 7
How do we discard LA cartridges?
In sharps container
What are the problems associated with needle use? [4]
Slide 8
What are types of LA injection? [3]
Slide 9
1. Local infiltration
2. Field block
3. Nerve block
Describe the techniques of LA on maxillary?
Slide 10 & 11
1. Supraperiosteal-LA will absorb into the bone going to the nerve in the pulp tissue
2. ASNB,MSNB &PSNB-are given buccally depending on the sections on the maxilla
3. Maxillary nerve block - if you’re working on the whole of the maxilla (1 quadrant)
4. Greater palatine nerve block
5. Nasopalatine nerve block
Buccal nerve block goes together with?
IAN
Why do you give Gow Gate mandibular nerve block? High mandibular nerve block
I the case where IANB failed or was not effective
When do you give the Vazirani Akinosi nerve block?
When the pt cannot open their mouth
35:00
Name four supplemental injections you can give for efficient LA? [4]
- Intrapulpal
- Intraosseous
- Intraligamental
- Intraseptal
What is the landmark when injecting PSA, MSA & ASA?
Mucobuccal fold beyond the apex of the tooth consent
Where does the greater palatine and lesser palatine nerve innervate? [2]
Slide 11
What is difference between direct and indirect technique of IANB?
- Direct- syringe enters the mouth from opposite premolar occlusal area towards the pterygomandibular space of the side where you want to work on
- Indirect- Occlusal surface of the teeth on the same side where your working from
What is the pterygomandibular space? And it’s borders? [5]
- The facial space of the head and neck
- Borders- Ant: pterygomandibular raphe, Post: parotid gland, Med: medialpterygoid plate & Lat: lingual plate of mandibular ramus
What are the contents of the pterygomandibular space?
- Inferior alveolar nerve + lingual nerve
- Maxillary artery
- Maxillary veins
Which nerves are successfully blocked with IANB?
- IAN
- Lingual nerve
- Mental nerve
- Incisive nerve
When do you use the Gow Gate technique?
- When the conventional IANB fails or you can not access the pterygomandibular due to fibrosis
Which never are anesthetized with successful Gow Gate techniques?
All nerves of IAN & Auriculotemporal n, N. to mylohyoid and Buccal nerve
Where do you target with Gow Gate?
Lateral side of condylar neck
When do you give the vazirani akenosi?
Slide 15
What is the target when performing Vazirane Akenosi technique?
The medial aspect of the mandibular ramus adjacent to the maxillary tuberosity
