What are the three categories used to classify the rate of periodontal disease progression?
When grading a patient's periodontitis, what is the standard clinical starting point?
Clinicians should initially assume Grade B and subsequently look for evidence to justify moving to Grade A or Grade C.

Evidence of no bone loss over 5 years.
What is the direct evidence criteria for Grade C periodontitis regarding bone loss over 5 years?

Less than \(0.25\).

HbA1c \(< 7.0\%\).
What hsCRP level is classified as an indicator for high systemic risk in Grade C periodontitis?
Greater than \(3\text{ mg/L}\).
What is the formula used in the indirect method to determine the periodontitis grade?
The ratio of the percentage of bone loss to the age.
Based on the bone loss/age ratio, what is the criteria for Grade A periodontitis?
< 0.25
0.25 - 1.0
<blockquote>
1.0
</blockquote>
1.0 - 2.0
Which of the following conditions is mentioned as a risk factor that can act as a grade modifier for periodontitis?
Asthma
Hypertension
Smoking
Obesity
What is the threshold for HBA1c levels in a diabetic patient that could lead to a grade modification for periodontitis?
Greater than 7%.
What is the clinical significance of c-reactive protein in the context of periodontitis?
It serves as a marker for the potential systemic impact of the inflammatory burden of periodontitis.
How is a patient categorized by grade if their bone loss/age ratio is greater than 1.0?
Grade C
Grade A
Grade B
Grade D
What is the primary goal of staging a periodontitis patient?
To classify the severity and extent of tissue damage and assess the complexity of managing long-term function and esthetics.
What is the primary goal of grading a periodontitis patient?
To estimate the future risk of disease progression, responsiveness to therapy, and the potential systemic health impact of periodontitis.
When assessing a new patient for periodontitis via radiographs, what specific finding indicates a suspicion of periodontitis?
Good diagnostic quality
Presence of calculus
Normal interdental bone levels
Detectable marginal bone loss
In the absence of radiographs, what clinical finding during periodontal assessment suggests a possible periodontitis case?
Pocket depth of 2mm
Detectable interdental clinical attachment loss (CAL)
Gingival bleeding
Presence of plaque
What threshold of buccal or oral recession combined with pocket depth is used to screen for potential periodontitis?
A pocket depth of more than \(3\text{mm}\).
Based on the decision-making algorithm, how is generalized gingivitis defined by bleeding on probing (BOP)?
BOP \(> 30\%\).
What are the BOP index classifications when a patient has no buccal/oral or interdental CAL?
10%: Generalised gingivitis
</blockquote>What local factors are assessed when determining the cause of attachment loss?
What criterion warrants a thorough periodontal charting in a patient with attachment loss?
Clinical Attachment Loss (CAL) of more than 1 on non-adjacent teeth.
If periodontal charting reveals no pocket depth of 4mm or more, how is the status interpreted based on the BOP value?
10% BOP: Gingival inflammation in a periodontitis patient
</blockquote>What is the clinical diagnosis if periodontal charting reveals pocket depths of 4mm or more?
Periodontitis, which requires further assessment to determine the stage and grade.
What is the threshold for classifying periodontitis as 'generalised' based on the extent of teeth affected?
More than 30% of all teeth affected.
Which of the following factors are used to define the 'severity' of periodontitis when establishing a stage?
Bite collapse, drifting, and flaring
Pocket depth, furcation, and tooth hypermobility
Previous periodontal treatment and patient history
Clinical Attachment Loss (CAL), bone loss, and periodontal tooth loss
What clinical factors are evaluated to determine the 'complexity' of a periodontal case?
What documentation is required to establish the stage of a patient with suspected periodontitis?
Which patient history factors should be assessed during a periodontal examination?
Overall systemic health, medications, and allergies
Family history of heart disease, smoking status, and age
Daily oral hygiene routine, diet, and frequency of dental visits
Reason for previous tooth loss, reason for extractions, and previous periodontal treatment
What diagnostic findings are necessary to confirm a case of periodontitis according to the periodontal appraisal flowchart?
A periodontal probing depth (PPD) of 4 mm or more.
What Clinical Attachment Loss (CAL) or bone loss pattern necessitates an immediate diagnosis of periodontitis stage 3 or 4?
CAL > 5 mm or bone loss reaching the middle or apical third of the root on two or more non-adjacent teeth.
Which level of furcation involvement mandates a diagnosis of periodontitis stage 3 or 4?
A furcation degree of 2 or 3.
If there is no furcation involvement, what pocket depth identifies periodontitis stage 3 or 4?
A pocket depth greater than 5 mm.
When pocket depth is between 3 mm and 5 mm and there is no furcation involvement, what specific clinical factor indicates periodontitis stage 3 or 4?
Any tooth loss caused by periodontitis.
Which of the following clinical findings immediately indicates periodontitis stage 3 or 4?
Furcation degree of 1
Furcation degree of 2 or 3
Pocket depth of 2 mm
No tooth loss
If a patient has no furcation involvement and a pocket depth between 3 mm and 5 mm, what would confirm a diagnosis of periodontitis stage 3 or 4?
Bone loss in the coronal third of the root
A history of good oral hygiene
CAL of 1 mm
Any tooth loss caused by periodontitis
If a periodontitis patient has no tooth loss, what is the clinical stage?
Stage 1 or 2.
What threshold of bone loss (CAL) characterizes Stage I periodontitis?
1-2 mm.
What threshold of bone loss (CAL) characterizes Stage II periodontitis?
3-4 mm.
What clinical factors determine if a case is classified as Stage IV periodontitis?
In the context of periodontal grading, what does the term 'previous existing records' refer to?
Old x-rays from the previous 5 years or periodontal charts.
What are the criteria for Grade A periodontal progression over 5 years?
Less than 2 mm of bone loss.
Which health conditions can lead to an upgrade in the grade of periodontitis for a patient?
What factors can lead to an upgrade in the grade of periodontitis?
What are the clinical criteria for a Currently Stable status in periodontitis?
What clinical parameters characterize the Currently in Remission status for periodontitis?
What defines a patient as Currently Unstable regarding periodontal disease?
What components should be included in a formal diagnostic statement for periodontitis?
Why do patients successfully treated for periodontitis remain classified as a patient with periodontitis for life?
The disease may progress at any time if risk factors are not well controlled or if periodontal maintenance is insufficient.
Does being a non-smoker automatically change a grade B periodontitis diagnosis to a grade A?
Only if the patient is young
No
Yes
Only if there is no bone loss
