Perio 2|138 Midterm Questions
Onset of prepubertal periodontitis occurs
a. before eruption of primary teeth
b. after eruption of permanent first molars
c. 2-3 years after eruption of primary teeth
d. immediately after eruption of primary teeth - ✔ ✔ d. immediately after eruption of primary teeth
Open tubules slowly close through a natural process of - ✔ ✔ crystallization or occlusion
Performs both hard and soft tissue procedures. Lacks the heat and vibration of a dental drill, so the
procedure is more comfortable for most patients. For soft tissue procedures it often eliminates the need
for suturing. Healing is much faster due to wound sterilization and atraumatic effect on surrounding
tissue. - ✔ ✔ lasers
Periodontal debridement includes instrumentation of every square millimeter of the root surface for
removal of plaque biofilm and calculus. It is intended to include the deliberate, aggressive removal of
cementum.
a. true
b. false - ✔ ✔ b. false- it is not meant to remove cementum or to produce glossy smooth roots.
Periodontal disease is considered to be controlled when:
a. the gingival tissue is firm, pink, and stippled
b. no pockets are deeper than 3mm
c. no bleeding on probing is present
d. calculus and plaque have been removed - ✔ ✔ c. no bleeding on probing is present
Periodontal maintenance is scheduled in: - ✔ ✔ three to four month intervals
Periodontal surgery, endodontic surgery, and implant placement are all components of - ✔ ✔
surgical phase
Pockets must be ___________ to disrupt bacterial colonies - ✔ ✔ instrumented
Procedure designed to remove cementum or surface dentin that is rough, impregnanted with calculus,
or contaminated with toxins or microorganisms (necrotic cementum) - ✔ ✔ root planing (srp)
, Procedure designed to remove cementum or surface dentin that is rough, impregnated with calculus, or
contaminated with toxins or microorganisms (necrotic cementum) - ✔ ✔ root planing
Protocol requires that full mouth debridement, SRD/SRP, and immediate oral disinfection procedures be
completed in:
a. 1 single appointment
b. 2 appointments within a 24 or 48 hour period
c. all of the above - ✔ ✔ c. all of the above
Re-evaluation appointments are scheduled how many weeks after initial nonsurgical therapy is
complete? - ✔ ✔ 4 to 6 weeks
Concavity just above the furcation entrance, on the root trunk, can be felt with a nabers probe tip. Feels
like a "speed bump". Nabers probe does not enter the furcation. Interradicular bone is intact. Pocket
formation into the fluting of the furca only. No gross radiographic evidence of bone loss - ✔ ✔ class I

true
Current instrumentation terminology utilizes the term periodontal debridement - ✔ ✔ true
Dental restorations, fixed and removable prosthesis, re-evaluation of overall response are all
components of: - ✔ ✔ restorative therapy
Dentinal hypersensitivity may arise following instrumentation during periodontal root debridement - ✔
✔ true
Done utilizing a combination of ultrasonic and hand instrumentation to the extent needed to reestablish
periodontal health and restore a balance between the bacterial flora and the host's immune response -
✔ ✔ periodontal debridement
During the healing process following gingival curettage, epithelial cell migration will begin in
a. 6 to 12 hours
b. 12 to 24 hours - ✔ ✔ b. 12 to 24 hours
