Under the 2017 classification, peri-implant mucositis is analogous to which periodontal condition?
Answer: Plaque-induced gingivitis
Peri-implant mucositis, like gingivitis, is an inflammatory lesion of the soft tissues that is reversible with plaque control and does not involve bone loss.
Which of the following represents a Grade A periodontitis patient?
Answer: No evidence of bone loss over 5 years and no risk factors
Grade A is characterized by slow or no progression, no bone loss evidence over 5 years, and absence of risk factors like smoking or diabetes.
Localized periodontitis is defined by what percentage of affected teeth in the 2017 classification?
Answer: <30%
Periodontitis is classified as localized when <30% of teeth are affected and generalized when ≥30% of teeth show interdental CAL.
Systemic diseases that have a major impact on periodontal tissues, such as Papillon-Lefèvre syndrome, are classified under which category in the 2017 framework?
Answer: Periodontitis as a direct manifestation of systemic disease
Periodontitis as a manifestation of systemic disease is a separate category for conditions where the systemic disease is the primary driver of tissue destruction.
In the 2017 classification, what distinguishes 'periodontitis' from 'periodontal manifestations of systemic disease'?
Answer: Presence of systemic disease as a risk modifier vs primary etiologic factor
In periodontitis, systemic conditions modify severity/progression, whereas in periodontal manifestations of systemic disease, the systemic condition is the primary etiologic driver.
A patient presents with furcation Class III involvement on multiple molars but is otherwise healthy. What is the minimum stage this patient can be assigned?
Answer: Stage III
Furcation Class III involvement is a complexity factor that places the patient at minimum Stage III, regardless of other findings.
Which finding would most strongly support upgrading a periodontitis patient from Grade B to Grade C?
Answer: Bone loss exceeding 1mm per year documented radiographically
Radiographic evidence of bone loss >1mm over 5 years (or >0.25mm/year) is primary evidence for Grade C rapid progression.
