ABGD Mock Oral Exam Flashcards
A patient comes into sick call complaining of very painful, bleeding gums, what is your diagnosis?
NUG
What are the classic signs/symptoms of NUG?
- Pain
- Punched out pipillae
- Bleeding (spontaneous)
- Fetor oris
- Pseudomembrane
- Systemic signs: Fever, Malaise, Leukocytosis
What is the etiology of NUG?
- Bacteria - Spirochetes
- Stress
- Smoking
- Poor OH
- Immunosuppression
What are proposed mechanisms for smoking’s effect on the periodontium?
- Altered blood flow
- Altered fibroblast attachment/function
- Altered microflora
- Depressed immune response (altered PMN phagocytosis/function)
- Increased pro-inflammatory cytokines
Name the bacteria that make up the red complex…
- PG
- TF
- TD
After non-surgical therapy, what can you expect in terms of changes in probe depths and attachment levels in pockets with an initial depth of: 1-3 mm, 4-6 mm, >7 mm?
- 1-3 mm: 0.17
- 4-6 mm: 0.96
- 7 mm or greater: 2.22
What are indications for surgical therapy in periodontics?
- Probing depths > 5 mm with bleeding
- Access for root debridement, regeneration, osseous surgery, etc.
- Remove bacterial reservoirs
Give 3 examples of local antimicrobial delivery agents and their active ingredient…
- Arestin - minocycline 1 mg
- Actisite - Tetracycline 25%
- Atridox - Doxycycline 10% - 7 days
- PerioChip - Chlorhexidine 2.5 mg 7-10 days
When would YOU use systemic antibiotics in periodontics?
- Medically compromised patient
- Acute conditions with systemic signs
- Refractory cases
- Patients at risk for bacteremias (joint replacement, IE)
- Aggressive disease
- Grafts
- Implants
- Regenerative procedures
What specific bacteria is associated with localized aggressive periodontitis?
A.a.
In crown lengthening, how many mm would you want to place the osseous crest from the anticipated restorative margin?
3 - 4 mm
What are the steps in osseous resective surgery?
- Bulk reduction
- Interdental fluting
- Elimination/reduction of defect walls
- Resection to achieve positive architecture
- Final shaping
What procedure would you use to treat this intrabond defect? (likely a picture of a 3 wall defect)
GTR
Name at least 3 graft materials available for use in this case and from where each is derived
- Bio-Oss (xenograft) bovine
- DFDBA (allograft)
- Autogenous bone (host)
- Alloplast (variety of materials and sources)
What are some available membranes to use?
- Gore-Tex
- Bio-Gide
- Osseoguard
- Cytoplast
- Guidor
- Capset
- BioMend
- BioMend Extend
How long does it take BioMend to resorb?
4-8 weeks
How long does it take BioMend Extend to resorb?
18 weeks
How long does it take Bio-Gide to resorb?
24 weeks
What is the composition/derivation of Bio-Gide?
Type I and III collagen of porcine origin
What is the composition/derivation of BioMend?
Type 1 collagen from bovine deep flexor tendon
List the steps of your surgical procedures in this case regarding GTR?
- Flap reflection
- Debridement
- Root biomodification??
- Cortical perforations
- Graft placement
- Membrane placement
- Primary closure
- Post-op antibiotics
- CHX
What are the indications for the treatment of recession?
- Progression of recession
- Discomfort
- Esthetics
- Pre-prosthetic
What are indications of implant success? i.e. implant success criteria (Albrecktsson)
- No clinical mobility
- No peri-implant radiolucencies
- < or equal to 0.2 mm annual bone loss after 1st year of function
- Lack of pain, infection, paresthesia, violoation of mandibular canal
Describe delayed-immediate implant placement
Give 2 advantages over an immediate implant
- Following extraction, wait 30-40 days to allow keratinization/soft tissue coverage over site, then place implant
- Better initial stability
- Complete closure possible
