|
T or F: absence of stippling in attached gingiva is characteristic of periodontal disease
|
False
|
|
|
What is the normal distance of the CEJ to the alveolar crest?
|
2 mm
|
|
|
Which area of the mouth has the narrowest band of facial attached gingiva?
|
Mandibular bicuspids
|
|
|
Interdental col:
1) What kind of epithelium is it initially covered by? 2) How is it affected by recessive gingiva? 3) How does it shape with the contact point? |
1) Non-keratinized stratified squamous epithelium
2) Flattens with the recession of the gingiva 3) Conforms to the shape of the contact point |
|
|
What structure on the oral surface of the free gingiva corresponds to the bottom of the sulcus?
|
Free gingival groove
|
|
|
What area of the mouth has no mucogingival junction?
|
Maxillary lingual
|
|
|
T or F: gingivitis always precedes periodontisis
T or F: not all gingivitis progresses to periodontitis |
1) T
2) T |
|
|
T or F: periodontitis is initiated by microbial challenge
|
T
|
|
|
T or F: periodontitis is site specific and only occasionally seen in generalized form
|
T
|
|
|
T or F: Periodontitis proceeds in bursts of activity
|
T
|
|
|
What factor is most responsible for the rate of periodontal disease progression?
|
Host immuno-inflammatory response
|
|
|
What are the two types of organisms that decline with the development of periodontitis?
|
Cocci and non-motile rods
|
|
|
T or F: the primary distinguishing characteristic between gingivitis and periodontitis
|
F
|
|
|
4 functions of pulp?
|
Formative, nutritive, nervous, defensive.
|
|
|
What are the formative functions of pulp? What are the two layers underneath the formative cells?
|
Odontoblasts make dentin. Zones underneath - cell free zone, cell rich zone
|
|
|
What does pulp use to nourish, and what does it nourish?
|
Pulpal capillaries - nourishes all elements of pulpodentinal complex
|
|
|
What kind of nerves are present in the pulp? What senses do they transmit and what do they help regulate?
|
Sensory and motor - transmit pain, help regulate blood vessels
|
|
|
What kind of irritants does the pulp defend against and how?
|
Physical, chemical, microbial - decrease in permeability of dentin, formation of secondary/reparative dentin, inflammatory/immunologic response
|
|
|
What can irritate the pulp and what results from pulp irritation?
|
Microbes, mechanical, chemical irritation causes inflammation, retrogressive changes, necrosis of pulp
|
|
|
In response to microbial irritants, what invades the pulp?
|
Local chronic inflammatory cells (macrophages, lymphocytes, plasma cells)
|
|
|
What is reparative dentin formed by?
|
Odontoblasts or new odontoblast-like cells from the cell rich layer
|
|
|
What is the purpose of intermediate materials under restorative materials? Examples of these materials?
|
Barrier to external irritants, therapeutic benefit like insulation under metal, or promote production of reparative dentin. Ex: cavity sealer (varnish, resin bonding agents), liners (CALCIUM HYDROXIDE), bases (RESIN-MODIFIED GLASS IONOMER)
|
|
|
Characteristics of cavity liners?
|
Minimal thickness, fluoride release, adhesion to dentin and/or antibacterial action that promotes health of pulp
|
