|
Definition
|
|
Term
True or false:
In chronic periodontitis, amount of destruction is consistent with the presence of local factors |
|
Definition
|
|
Term
Where will you most likely see the most plaque? |

mandibular incisors (sublingual glands)
1st maxillary molar (parotid gland) |
|
|
Term
What is NOT a secondary etiology of periodontitis?
Calculus Overhanging restorations Perio-endo lesions Bacterial plaque Open contacts with food impaction Occlusal trauma Smoking Systemic disease |

What is when a crown is prepared too deep into the where the attachment should be causing chronic inflammation (mistake of restorative dentistry)? |
|
Definition
violation of biologic width |
|
|
Term
In violation of biologic width, what 2 zones do we violate? |
|
Definition
Zone of epithelium attached to tooth Zone of connective tissue attached to tooth |

|
Definition
|
|

|
Term
What is the severity of periodontitis based on? |
|
Definition
Based on the amount of Clinical Attachment Loss (CAL) |
|
|
Term
What are the measurement of clinical attachment loss for slight, moderate, and severe? |
|
Definition

|
|
Term
**What teeth are most severely affected by chronic periodontitis? |
|
Definition
Maxillary molar >>> Mandibular canines Interproximal sites > labial surfaces |
|
|
Term
What two things set aggressive and chronic periodontitis apart? |
|
Definition
In aggressive,
microbial challenge can be far more virulent host response to plaque will cause more inflammation and bone loss (low tolerance to plaque) |
|
|
Term
What all initiates the host-mediated destruction? |
|
Definition
Cytokines and inflammatory mediators IL-1, IL-6,IL-8, TNF-α, PGE2 |
|
|
Term
What are the 4 phases of host response to periodontitis? |
|
Definition
1) acute bacterial challenge phase (PMNs) 2) acute inflammatory response (macrophages, inflammatory mediators) 3) immune response phase 4) regulation and resolution phase (Challenge less well controlled by host because of persistent bacterial aggression and contribution of host response modifiers (smoking, systemic disease, genetics) |

|
Term
What is a pocket formation around several/all primary teeth accompanied by bone loss and early exfoliation? |
|
Definition
prepubertal periodontitis |
|
|
Term
What is prepubertal periodontitis most often associated with? |
|
Definition
immune disorders, usually neutrophil chemotaxis disorders were present
Some forms considered complication of systemic disease |
|
|
Term
What is the type of periodontitis that affects permanent dentition in teenagers that have an absence of local factors (decay/filling), generally at the onset of puberty?
What teeth does it usually affect first? |
|
Definition
juvenile periodontitis (or localized aggressive periodontitis)
1st molars and incisors |
|
|
Term
What type of periodontitis has a tendency of cases to aggregate in families? |
|
Definition
localized aggressive periodontitis |
|
|
Term
True or False:
Aggregatibacter actinomycetemcomitans (A.a), a highly leukotoxic strain, can cause localized aggressive periodontitis alone. |
|
Definition
False
some populations of patients with LAP do not harbor A. actinomycetemcomitans and in still others P. gingivalis may be etiologically more important.
It should be remembered, however, that all dental plaque- induced periodontal diseases are mixed infections and none of them is caused by a single pathogen |
|
|
Term
What virulence factor of A.A. forms pores in neutrophil granulocytes, monocytes, and some lymphocytes, which consequently die because of osmotic pressure? |

|
Definition

|
|
Term

|
Definition
|
|
Term
