where does the cementum receive its blood and nutirent supply
a)trigeminal nerve b)dentoginival plexus c)periodontal ligament d)none |
a)trigeminal nerve-incorrect bc this structure provides sensory fxn to many maxillary and mandibular tissues and structures
b) dnetogingival plexus (incorrect bs this is a netowrk of blood vessels located in gingival connective tissue below gingival sulcus c) PERIODONTAL LIGAMENT- nutrients from the alveolar bone pass through canaliculi in pdl |
|
what is the name of the bone that lines the tooth socket
|
alveolar bone proper
cribiform plate lamina dura (xrays) |
|
what are the functions of the pdl
|
sensory- pain and pressure senstation to teeth
formative- builds and maintains cementum and alveolar bone of tooth socket resorptive- remodels alveolar bone in response to pressure |
|
what is the order inflammation spreads in horizontal bone loss
|
gingival connective tissue
pdl alveolar bone |
|
perio pockets are the pathological deepening of the gingival sulcus as a result of
|
the apical migration of the JE
destruction of the pdl fibers destruction of alveolar bone |

|
the apical migration of the JE
destruction of the pdl fibers destruction of alveolar bone |
|
define prevalence and incidence
|
prevalence- # of cases of disease over time
incidence- # of new cases |
|
what are local contributing factors
|
calculus
faulty restorations overhang NOT tobacco- systemic |
|
describe the bacteria responsible for periodontal disease
|
aa- transmisible in family members
b forsythus- found in deep perio pockets, aggressive perio f nucleatum- beginning stages of gingivitis p gingivalis- moderate perio |
|
what is the best way to combat plaque biofilm
|
with mechanical distruption (brush and floss, hygienist)
|
|
which of the following is not a local contributing factor
a) removable dneture b) calculus c) tetracycline d) bruxism |
c) tetracycline is systemic
|
|
define functional and parafunctional occlusal forces
|
funcitonal occlusal forces- forces caused by normal actions like chewing
parafunctional- caused be abnormal functions like clenching or bruxism |
|
what type of calculus is the most difficult to remove
|
1. direct contact of calcified component- interlocked relationsihp with tooth
2. tooth irregularities like cracks 3. attachment to pellicle |
|
which med causes gingival hyperplasia
a) phenytoin (dilantin) b) ibuprofen (advil midol) c) tetracycline (achromycin) d) tylenon |
A) PHEYNYTOIN DILANTIN
ibuprofen- causes xerostomia tetracylcline- therapy in recurrenet apthous ulcers tylenol- none |
|
which periodontal disease presents as a red band along the gingival margin which may or may not be accompanied by occasional bleeding and disscomfort
|
linear gingival equilibrium (LGE)
other disease: NUG- gorm of gingivitis that involves tissue necrosis limited to gingivitis NUP- severe pain, loosening teeth, bleeding "deep jaw pain" |
|
what are nonplaque induced gingival lesions associated with
|
viral and fungal infections
allergic reactions mechanical trauma |
