final exam Flashcards
_____ trauma from occlusion is excessive forces on teeth with NORMAL PERIODONTIAL SUPPORT
primary
______ trauma from occlusion is NORMAL or EXCESSIVE FORCES impact teeth with COMPROMISED PERIODONTAL SUPPORT
secondary
what is the effect of occlusal forces on the periodontium influenced by?
magnitude, duration, direction, frequency
what are the 3 stages of tissue responses to increased occlusal forces?
stage I- injury
stage II- repair
stage III- adaptive remodeling of periodontium
what are the radiographic signs of trauma from occlusion?
- a “vertical” rather than “horizontal” appearance of destruction affecting interdental septum
- radiolucency and condensation of the alveolar bone
_____- the movement of a tooth out of its natural position as a result of periodontal infection
pathological migration
_____- the physiological process maintained by tooth proximal contacts in normal dentition
mesial migration
the more ____ the application of an intermittent force, the more injurious the force is to the periodontium
frequent
what are the mobility values?
0 = within physiologic limits
1 = less than 1 mm BL/MD
2 = 1mm or more in a BL/MD direction
3 = exceeding 1mm and DEPRESSIBLE oclusso-apical direction
pressure and tension zones will develop within the _____ and ____ parts of the periodontium
marginal, apical
in the absence of ___ there is no apical down-growth of the JE
inflammation
when the tooth is exposed to forces which produce “BODILY” tooth movement, the pressure and tension zones, depending on the direction of the force, are ________
extended over the entire tooth surface
the supra-alveolar connective tissue is not affected in conjunction either with _____ or with ______ of the teeth
tipping, bodily movement
neither unilateral forces nor jiggling applied to teeth with a healthy periodontium, result in _____ or _____
pocket formation, in loss of connective tissue attachment
*can trauma from occlusion, without inflammation, induce periodontal tissue breakdown?
NO!!!!!!!!
periodontal recall
every 6 months for cleaning
periodontal maintenance
3 months recall
gingivitis: __ months recall
6
periodontitis: __ months recall
3
what are the expected effectiveness relating close to debridement procedures:
1-3mm - 86%, 4-6mm - 43%, >6 mm- 32%
*after SRP and root planing, the dentogingival unit heals by formation of a ____ to the root surface
long junctional epithelium
prophylaxis =
6 months RECALL
SPT (supportive periodontal therapy) =
3 months MAINTENANCE
who is responsible for SPT?
- mild or localized- general dentist
- moderate- general dentist or specialist
- advanced- specialist
____ - deep awareness of the suffering of another coupled with the wish to relieve it
compassion
