Lecture 5: Case Selection & Recall Responsibilities Flashcards
The single most important factor affecting RCT success:
Case selection
To avoid great risk or serious error, you must examine and fully understand: (4)
- the patient
- the complexities of the root canal system
- the specialized techniques required
- have the appropriate training, instrumentation & equipment
For case selection, you should consider: (2)
- the great variety of personality types
- your current patient management skills
List the primary considerations for RCT: (2)
- Does the patient WANT endo treatment?
- Does the patient UNDERSTAND the commitments required of the treatment
List the subsequent considerations for RCT: (4)
- Is the tooth strategic & functional?
- Is the tooth restorable?
- Is it periodontally sound?
- Is the investment justified by the benefits
T/F: Missed canals have a significant impact on treatment prognosis
True
NEVER start RCT on any tooth for which:
an excellent result cannot be reasonably expected.. in your hands at that time with that patient
The standard of care expected of the general dentist is _______ as that expected of the endodontic specialist
EXACTLY the same
The _____ has developed a form which will help you determine the difficulty/risk level of each case in question
AAE
Once you determine the _____, you have a reasonable basis to divide if you should ____ the case or _____

true
The best time to refer is: (3)

Who did Dr. Weisleder discuss that was a great mentor in endodontics to her?
Dr. Ronald R. Riley
What did Dr. Ronald Riley contribute to in the oral surgery journal volume 37?
“endodontic recall procedures”
List some of the key discussion points from Dr. Ronald Riley: (5)
- outcome discovery
- validation of your treatment
- professional responsibility
- ethical & moral obligation
- legal mandate
When should you recall if your patient reports adverse signs & symptoms?
Recall immediately
What are some signs and symptoms that require you to recall the patient IMMEDIATELY?
- infection
- pain or continued sensitivity
- draining sinus tract
Minimum recall interval for the “greatest improvement”
6 months - 1 year (Klevant 1983)
At UMKC, as a student dentist you have required recall of a minimum of ____ RCT patient recalls
2
T/F: at UMKC you may be asked to recall RCT patients of graduates
true
The purposed of endodontic recall is to: (4)
- assess the status of the treated tooth
- determine need for additional treatment
- document recall procedures
- document 3 unsuccessful attempts???
When assessing the status of the treated tooth (purpose of endodontic recall) you should examine the tooth to see if it is:
- healed/healing
- functional
- diseased
For a recall endo patient, what are we looking for radiographically?
1) 2 diagnostic P/A films
2) potential CBCT
3) normal PDL width
4) PARL eliminated
5) Normal lamina dura
6) Normal to fine-meshed osseous trabeculae
7) No resorption
What radiographs will you take for a recall patient?
