What is gomphosis and what does it provide to good oral health? |
|
Definition
Its the attachment between the tooth and gums. It provides a seal around the tooth |
|
|
Term
What are two responsibilities of the periodontium? |
|
Definition

|
|
|
Term
What are the supporting tooth structures? |
|
Definition
- alveolar bone
- periodontal ligament
- cementum
- gingiva
|
|
|
Term
What does the mucogingival junction divide? |
|
Definition
Areas of attached gingiva and alveolar mucosa |
|
|
Term
What types of bone are in the periodontium? |
|
Definition
- Cancellous bone
- alveolar bone = PDL attachment
|

Definition
|
|
Term
What is the difference between a sulcus and a pocket? |
|
Definition
Sulcus is present in healthy mucosa, but sulci turn into pockets with disease |
|
|
Term
Whats the difference between gingivitis and periodontitis? |
|
Definition
Gingivitis is only involving the inflammation of the gums, periodontitis involves the entire periodontium |
|
|
Term
What is the definition of gingivitis? |
|
Definition
|
|
Term
What is the primary etiology of periodontitis? |
|
Definition
|
|
Term
What are some of the symptoms of periodontitis? |
|
Definition
- inflammation extends beyond the gingiva
- apical migration of junctional epithelium
- pocket formation
- bone loss
- attachment loss
|
|
|
Term
Why can't we use solely antibiotics to treat periodontitis? |
|
Definition
Because of the bacteria in the extracellular matrix |
|
|
Term
What is the plaque index? |
|
Definition
A tablet is given to the patient to chew up and stains the plaque, 30% or more teeth with stains not good. |
|
|
Term
How is attachment levels determined? |
|
Definition
The gingivial recession in addition to the probing depth |
|
|
Term
How many probing measurements are there per tooth? |
|
Definition
|
|
Term
How would one record a pocket that is 4.5 mm deep? |
|
Definition
|
|
Term
The results of clinical attachment are different from probing depth how? |
|
Definition
Clinical attachment determines what was already lost, probing depth gives us up to date info |
|
|
Term
During probing, what distance are you recording? |
|
Definition
The distance from the gingival margin to teh base of the pocket |
|
|
Term
What are the different grades of the furcation analysis? |
|
Definition
- Grade 1 = incipient , can feel catch
- Grade 2= Insert into furcation but not all the way thru
- Grade 3 = probe all the way through
- Grade 4 = can see without probes
|
|
|
Term
What are the furcation grade symbols for the exam chart? |
|
Definition
- Grade 1 = V with point into the root
- Grade 2 = non colored triangle
- Grade 3 = colored triangle
|
|
|
Term
What is the clinical symptom of a mucogingival junction defect? |
|
Definition
Periodontal probe goes through the mucogingival junction |
|
|
Term
What is the miller classification for mobility? |
|
Definition
- Uses two solid instruments to push tooth
- Numerical value for amount of mobility
- 0= normal mobility (less than 0.5mm)
- 1 = slightly more than normal (greater than 0.5mm and less than 1mm)
- 2= Greater than 1mm M-D or B-L
- 3= same as 2, but with vertical component

|
Definition
Evaluation of the anatomy of the crestal bone and interproximal caries |
|
|
Term

|
Definition
Consistant level of bone loss throughout mouth |
|
|
Term
What is vertical bone loss? |
|
Definition
uneven levels of bone loss around a tooth |
