“Periodontal liability claims pertaining to periodontics most commonly allege:
–failure to diagnose
–failure to inform
–failure to refer
–or failure to treat
Localized periodontitis is ______% of the teeth
less than 30%
Generalized periodontitis is _____% of the teeth
greater than 30%
Perio Type I is ________
Gingivitis only
No bone loss
Perio Type II is
Slight up to 15% bone loss
4-5 mm pockets
2 or greater CAL
Perio type III is
Moderate 16 to 30% bone loss
> or equal to 5mm and 7mm pockets
Greater than 3 less than 5 mm CAL
Perio Type IV is
Advanced greater than 30% bone loss
> or equal to 7mm pockets
Greater than 5mm CAL
Perio Type V is
Refractory periodontitis
The only accurate method of detecting and measuring periodontal pockets is with _______ and not detected by ____
a probe
radiographs
Probing measurements are used to
–Support treatment planning decisions
–Assess periodontal disease status
–Guide the clinician during root detoxification
–Evaluate the success of treatment
pocket may be as much as _______ in the presence of inflammation
1 mm deeper
Clinical Depth is the _________ plus ________
biologic depth
tissue penetration
Clinical attachment loss is the distance between the
CEJ and the most apical extent of the epithelial attachment
Grade I furcation
Curvature of the concavity can be felt but the interradicular bone is intact
Grade II furcation
Probe penetrates the furcation but does not pass all the way through
Grade III furcation
loss of interradicular bone and probe passes through and through
Grade IV furcation
Loss of interradicular bone completely through and through AND recession allowing visualization of complete furcation
Mobility 1
Slight 1mm in each direction
Mobility 2
Moderate about 2 mm
Mobility 3
More than 2mm and depressible in socket
Primary occlusal trauma
Tooth mobility due to occlusal trauma but there is no bone loss
Secondary occlusal trauma
Tooth mobility due to loss of support(bone)
Amount of mobility depends with secondary occlusal trauma on
–severity and distribution of bone loss
–length and shape of roots
–root size compared to crown size
Tooth mobility can be caused by
–Inflammation in the absence of bone loss–Periapical abscess
–Trauma – acute or chronic
-Orthodontics
–Pregnancy
Fremitus is the
The movement of teeth during function frequently associated with increased bone and attachment loss
The width of attached gingiva is the distance between the
mucogingival junction and the bottom of the pocket or sulcus
The width of attached gingiva is considered to be inadequate if the
free gingival margin moves when the lip or cheek is stretched, or is 1 mm or less
Pathologic migration of teeth is
tooth displacement that occurs when bone destruction upsets the balance among the factors that maintain tooth position
pathologic migration
What is the radiographic assessment of implants
X-rays every 3 months for the first year and then every one to two years
The normal distance from the CEJ to the level of bone is
1 to 2 mm
Ulceration is
the absence of epithelium
What is suppuration
An accumulation of dead cells Primarily PMN polymorhonucleocytes
Cortical bone is ______ and radiographically appears as ______ called the _____
the dense outer surface of bone
a thin white line
lamina dura
An indicator if health is when the contour of the interdental bone is parallel to an ________
imaginary line drawn between the CEJ's of adjacent teeth
The CEJ's will still be parallel but not ________ when an adjacent tooth is ______ or ______
horizontal
tilted
erupted to a different height
The alveolar crest is _______ from the CEJ
1-2mm
The space between the cementum and the lamina dura is filled with the ______ which appears _____ and in most cases widens on the radiograph indicating ______
periodontal ligament
radiolucent
tooth mobility
Describe some early changes of bone loss
–Fuzziness at the alveolar crest (loss of lamina dura)
–Widening of the PDL space (triangulation)
–Radiolucent areas in the interseptal bone
The majority of the cells in the gingival crevicular fluid is
