T/ F CARE AND HANDLING OF SYRINGES Syringe should be washed and rinsed after each use. It should be autoclaved in the same manner as other surgical instruments
T
26
T/ F CARE AND HANDLING OF SYRINGES After every 5 autoclavings, it should be dismantled and all threaded joints should be lightly lubricated
T
27
T/ F CARE AND HANDLING OF SYRINGES The harpoon should be cleaned with a brush after each use
T
28
T/ F CARE AND HANDLING OF SYRINGES Replace harpoon once it fails to embed with the rubber stopper
T
29
PROBLEMS WITH SYRINGes [4]
Leakage during injection Broken cartridge Disengagement of the harpoon from the plunger during aspiration Surface deposits
30
vehicle that permits local anesthetic solution to travel from the dental cartridge into the tissues surrounding the needle tip
NEEDLE
31
vehicle that permits local anesthetic solution to travel from the dental cartridge into the tissues surrounding the needle tip
NEEDLE
32
stainless steel and disposable
NEEDLE
33
represent the most fear-inducing component of the local anesthetic armamentarium
NEEDLE
34
Fear of needles is termed as.
trypanophobia
35
weakest part of the needle
hub
36
the point or tip of the needle
BEVEL
37
provide a cutting surface allowing the needle to penetrate mucosa with as little resistance as possible
BEVEL
38
KINDS OF BEVELS [5]
→ short → medium → long → multi-beveled → scalpel
39
produces the most effective puncture while eliciting the least amount of trauma
multi-beveled
40
allows needle insertion with less tissue displacement, thus requiring less force to penetrate the mucosa
scalpel
41
recommended for infiltration and periodontal ligament (PDL) injections
scalpel
42
not recommended for nerve blocks where the nerve may be directly contacted
scalpel
43
T/ F The greater the angle of the bevel with the long axis of the needle, the greater will be the degree of deflection as the needle passes through hydrocolloid (or the soft tissues of the mouth). A needle tip centered on the long axis will deflect to a lesser extent than a beveled-point needle, whose point is eccentrically situated
T
44
refers to the diameter of the lumen of the needle
GAUGE
45
diameter of its lumen
SHAFT
46
plastic or metal piece through which the needle attaches to the syringe
HUB
47
weakest or fragile component of the needle
HUB
48
extends through the needle adaptor and perforates the diaphragm of the local anesthetic cartridge
CARTRIDGE-PENETRATING END
49
technique in which the operator rotates the handpiece or needle in a back-and-forth rotational movement while advancing the needle through the soft tissue
BIROTATIONAL INSERTION TECHNIQUE (BRIT)
50
deflection of the needle as it passes through soft tissue is a consideration when a needle must penetrate a greater thickness of soft tissue
MINIMIZING NEEDLE DEFLECTION
51
“PROBLEMS WITH NEEDLES [3]
Pain on insertion Breakage Pain on withdrawal
52
Name? synthesized procaine hydrochloride in powdered form
Alfred Einhorn (1905)
53
Name? made and patented the carpule and invented the brass syringe
Harvey S. Cook (1920)
54
COMPONENTS of THE CARTRIDGE [4]
→ cylindrical glass tube → stopper (plunger, bung) → aluminum cap → diaphragm
55
receives the harpoon of the aspirating syringe
STOPPER
56

61
function: o to increase safety and duration of depth of action of the local anesthetic A. LOCAL ANESTHETIC DRUG B. SODIUM CHLORIDE C. STERILE WATER D. VASOPRESSOR OR VASOCONSTRICTOR DRUG E. SODIUM (META)BISULFITE F. METHYLPARABEN
D
62
→ function: o antioxidant → prevents oxidation of the vasoconstrictor by oxygen A. LOCAL ANESTHETIC DRUG B. SODIUM CHLORIDE C. STERILE WATER D. VASOPRESSOR OR VASOCONSTRICTOR DRUG E. SODIUM (META)BISULFITE F. METHYLPARABEN
E
63
possesses bacteriostatic, fungistatic, and antioxidant properties A. LOCAL ANESTHETIC DRUG B. SODIUM CHLORIDE C. STERILE WATER D. VASOPRESSOR OR VASOCONSTRICTOR DRUG E. SODIUM (META)BISULFITE F. METHYLPARABEN
F
64
removed because: o dental cartridges are single-use items o reports of repeated exposure led to increased allergic reactions A. LOCAL ANESTHETIC DRUG B. SODIUM CHLORIDE C. STERILE WATER D. VASOPRESSOR OR VASOCONSTRICTOR DRUG E. SODIUM (META)BISULFITE F. METHYLPARABEN
F
65
PROBLEMS WITH CARTRIDGES [8]
→ bubble in the cartridge → extruded stopper → burning upon injection → sticky stopper → corroded cap → “rust” on the cap → leakage during injection → broken cartridge
