Q

what are the advantages of periodontal ligament injections

A
  • no anesthesia to lip, tongue, other soft tissues
  • minimum dose of LA necessary (0.2 mL per root)
  • rapid onset
  • less traumatic than conventional block injections

Q

what are the disadvantages of periodontal ligament injections

A
  • leakage of LA in patient’s mouth / bad taste
  • excessive pressure or overly rapid injection could break glass carpule
  • excessive pressure can cause tissue damage
  • potential for extrusion exists if too much pressure or volume are used

Q

what are the advantages of intraseptal injections

A
  • no anesthesia of lip, tongue
  • minimum dose of LA necessary
  • minimized bleeding during surgical procedure
  • atraumatic
  • useful on periodontally involved teeth (avoids infected pockets)

Q

what are the disadvantages of intraseptal injections

A
  • leakage of LA in patient’s mouth / bad taste
  • multiple tissue punctures may be necessary
  • short pulpal anesthesia
17
Q

what needle is used in intraseptal injections

A

27 short

18
Q

where does insertion occur in the intraseptal injection

A

center of interdental papilla adjacent to the tooth being treated

19
Q

what is the target area of intraseptal injections

A

center of interdental papilla

20
Q

what is the specific technique for intraseptal injections

A
  • bevel toward apex
  • penetrate at 45 degree angle to long axis of tooth until contact with bone
  • deposit 0.4 ml in no less than 20 sec
21
Q

PDL and Intraseptal injections both provide the same amount of pulpal anesthesia. PDL and Intraseptal injections both require slow deposition of anesthetic solution, at a minimum of 20 sec.

a - the first statement is TRUE, the second statement is FALSE
b - the first statement is FLASE, the second statement is TRUE
c - both statements are TRUE
d - both statements are FALSE

A

b - the first statement is FALSE, the second statemEnt is TRUE

PDL injections provide much more pulpal anesthesia than the inraseptal injections

22
Q

what injection involves anesthetizing the terminal nerve endings at the site of injection and in adjacent hard and soft tissues, along with bone, soft tissue, and root structure in the area of the injection

A

intaosseous injection

23
Q

what is the indication for intraosseous injections

A

pain control for treatment on single or multiple teeth in a quadrant

24
Q

what is the contraindication of intraosseous injections

A

infection or severe inflammation at injection site

25
Q

what are the advantages of intraosseous injections

A
  • no anesthesia of lip, tongue
  • minimum dose of LA necessary
  • immediate onset
26
Q

what are the disadvantages of intraosseous injections

A
  • requires specidal device (X-Tip or Stabident system)
  • high incidence of heart palpitations when using LA w/ vasoconstrictor (plain recommended, if must use vaso then 1:200,000 epi)
27
Q

what is the specific technique of intraosseous injections

A
  • infiltate first
  • perforate cortical plate 2 mm apical to gingival margin at area of interdental papilla, distal to tooth being treated (AVOID MENTAL FORAMEN)
  • hold guide sleeve in place as drill is withdrawn, sleeve remains in place w/ adequate anesthesia
  • injection delivered via sleeve w/ regular local anesthetic syringe
  • dosage varies
28
Q

what type of injection involves anesthetizing the terminal nerve endings at the site of injection in the pulp chamber and canals of the involved tooth

A

intrapulpal injection

29
Q

what are the indications for intrapulpal injections

A

when pain control is necessary for removal of pulp tissue or other endodontic treatment in the absence of adequate anesthesia after repeated attempts with other techniques

30
Q

what are the contraindications for intrapulpal injections

A

NONE

31
Q

what are the advantages of intrapulpal injections

A
  • no anesthesia of lip, tongue
  • minimum volume of LA
  • immediate onset
32
Q

what are the disadvantages of intrapulpal injections

A
  • traumatic (often associated w/ brief, intense pain)
  • short duration (15-20 min)
  • short pulpal anesthesia
33
Q

what needle is used for the intrapulpal injection

A

25 or 27 short

34
Q

what is the specific technique of intrapulpal injections

A
  • insert needle into pulp chamber
  • insert firmly for pharmacologic and pressure anesthesia
  • deposit 0.2 - 0.3 mL
