Q

What are the three set parameters?

A

1) rate of periodontitis progression;
2) recognized risk factors for periodontitis progression;
3) risk of an individual’s case affecting the systemic health

16
Q

What is the rate of disease progression?

A
  • Change or advancement of destruction as compared from previous visit
  • Slow rate of progression: May be modified by systemic/environmental/ factors
  • Current view
    1. Destruction not continuous
    1. Occurs in short bursts with destruction
    1. Random occurrence over time
    1. Random sites in mouth
17
Q

What is increased disease progression ?

A
  1. Rapid progressive lesions
    * Interproximal areas
    * Areas of greater plaque accumulation
    * Areas inaccessible to plaque control
    *. Furcations
    * Overhangs
    * Malposed teeth
    * Areas of food impaction
  2. U nequal rate of progression of affected sites
18
Q

What are the predictors or disease progression?

A
  • Previous history of periodontitis (risk determinant)
  • Greater risk for progressive disease
    If not successfully treated
    Plaque allowed to accumulate in a treated patient
  • Importance of monitoring and maintenance
19
Q

What are the primary Criteria for grading?

A
  • Direct evidence of progression
  • Indirect evident of progression
20
Q

What are some grading modifiers?

A
  • risk factors like smoking diabetes
21
Q

What are the causes of periodontitis ?

A
  • Pathogenic bacteria
  • Destruction consistent with local factors
  • Oneset and severity determined by: plaque biofilm, host immune response interaction and evironment
22
Q

What are the symptoms of periodontitis?

A

▪ Red or swollen gingiva
▪ Bleeding during brushing
▪ Bad taste
▪ Persistent bad breath
▪ Sensitive teeth
▪ Loose teeth
▪ Purulence
* Usually painless
* mimics odontogenic pain
* Gingival tenderness or itching
* Pain associated with food impaction

23
Periodontitis affect deep tissues of?
the periodontium
24
True or False Appearance of gingival tissues is not a reliable indicator of the presence or severity of periodontitis
True
25
What are the clinical appearance of gingival tissue
▪ Evident Clinical Signs ▪ Bright red to purple tissue ▪ Minimal Signs ▪ Pale pink ▪ Often mistaken for health ▪ Fibrotic ▪ Pocketing
26
What are some clinical features?
▪ Tissue enlargement ▪ Tissue redness ▪ Bleeding on probing ▪ Periodontal pockets ▪ Loss of stippling ▪ Fibrotic tissue ▪ Exudate / suppuration ▪ Subgingival calculus ▪ Flat or cratered papilla ▪ Blunted or rolled gingival margins ▪ Tooth mobility in advanced cases ▪ Alveolar and supporting bone destruction
27
What are the variables of inflammation?
* Localized One site/one tooth Several sites/one tooth Several teeth * Generalized Entire dentition
28
What is of horizontal bone loss?
* Most prevalent bone loss presentation * Can occur in individuals of any age ▪ Most common in adults >30 ▪ Old Names  Chronic Adult Periodontitis  Chronic Periodontitis
29
COMPLEXITY: VERTICAL BONE LOSS EXTENT: MOLAR-INCISOR PATTERN
▪ Less common than horizontal ▪ Old Names  Early Onset Periodontitis (1989)  Included prepubertal periodontitis, juvenile periodontitis and rapidly progressive periodontitis  Aggressive Periodontitis (1999)
30
What are the three overlapping issues for complexity- vertical bone loss?
* Time * Place (Topographic location) * Person (Age, gender and race)
31
What are the general characteristics for complexity- vertical bone loss?
* *No obvious signs/ symptoms of systemicdisease * Rapid destruction of attachment * Rapid loss of supporting bone High risk for tooth loss * Affected tissue may have normal * appearance * Periodontal pockets * Small amount of plaque * Severity not consistent with amount of plaque * Immune deficiencies * Genetic links possible contributing factors * * Presentation with age (puberity to < 30) * Gender affiliation * Inflammatory/immune response * maybe self arresting
32
What are the clinical features for complexity- vertical bone loss during the FIRST PRESENTATION?
* Characteristic distribution of lesions 1st molar and incisors * Inter proximal attachment loss on at least two permanent teeth One of which is a 1st molar Involving no more than two teeth other than first molars and incisors
33
What are the clinical features for complexity- vertical bone loss during the SECOND PRESENTATION?
 Characteristic distribution of lesions Most teeth  Generalized interproximal attachment loss  Affecting at least 3 permanent teeth Other than 1st molars and incisors
34
What are the clinical features for vertical bone loss with molar incisor patterns?
Lack of clinical inflammation despite deep periodontal pockets
35
What is vertical bone loss extent: molar incisor pattern disease progression ?
* Rapid progression * 3-4x faster than horizontal bone loss development * **Diastema formation ** * Increase mobility of 1st molars * Periodontal abscesses * Pain
36
What are the microbiological factors for Complexity: Vertical bone loss with molar incisor pattern ?
* A. actinomycetemcomitans- primary pathogen * Red complex bacteria involvemnet: P. gingivalis, T. Forsythia * Other bacteria include: P. Intermedia, E. Corrodens, C. Rectus, Capnocytophaga species * Amount of plaque minimal * Inconsistent with amount of destruction * Rarely forms calculus
37
What are the radiographic findings for vertical bone loss- molar incisor pattern ?
* vertical bone loss (1st molar and incisors) * arc shaped bone loss
38
How to define a periodontitis case?
Clinically: * interdental CAl is detectable at Greater or equal to 2 * Buccal/ lingual CAL is 3 or greater with pocketing > 3 is detectable but cannot be non-perio because of other factors.
39
What are some causes that can make a case non-periodontitis-related?
* recession due to trauma * Caries within the cervical 3rd * CAL on the distal of a second molar and associated with malpositon/extraction of thirds * An endodontic lesion draining through the marginal periodontium * Occurrece of a vertical root fracture
