PreClinic Exam 4

Preclinic Explorers, Perio Probe and Gingival Description

QuestionAnswer
the ODU 11/12 explorer can be used on both anterior and posterior teeth (T/F) true
The ODU 11/12 explorer can be used on both supragingival and subgingival tooth true
the best place to check end selection for the ODU 11/12 explorer in anterior teeth is
the appropriate stroke when using the ODU 11/12 for calculus detection is assessment stroke, exploratory stroke, feather light stroke
what is not a appropriate use of the EXP #5 supragingival and subgingival calculus detection
what do we put on all gingival descriptions? distribution severity location
what are the assessment instruments? mirror probe explorer
what is the normal gingival depth? 1.8 mm
what is the obran type explorer? anterior subgingival explorer has bent round back so goes subgingival
what is the ODU 11/12? supra/sub gingival anterior and posterior
what is the shepord's hook used for examine pit and fissures
where do you check end selection for explorers on anterior teeth? between 8 and 9 on the surface you are working on make sure to fulcrum
where do you check end selection for explorers on posterior teeth? between most distal teeth, surface you are working on terminal shank must clear crown
what is a calculus spicule? under contacts, at line angle, midline of tooth tiny little overhangs, stand alone pieces
what is a calculus ledge? lays like a shelf, long ridge of calculus running parallel to gingival margin
what is a calculus ring? encircles the entire tooth, ridge of calculus parallel to gingival margin
what is a calculus veneer? flat piece of calculus up against the tooth
which probe is preferred for clinical research? Hu-Friedy PCPUNC 15 very specific markings
which probe is preferred for implants? Hu-Friedy 3-6-9-12 mm plastic so doesn't scratch the titanium
which probe is preferred for epidemiology? WHO probe general estimate for classification for patient
which probe is used for measuring furcations? Naber's probe
where should the gingival margin fall in a natural healthy tooth? at the level of the CEJ
what is recession caused by tooth brush abrasion junctional epithelium migration down the root
what is the normal measurement of the junctional epithelium to bone? 1.5 mm
what is the normal measurement of the bone to the CEJ 2 mm
how do you calculate clinical attachment level in presence of gingival recession add the probing depth to the gingival margin level recession is greater attachment loss so you add it
what is a pesudopocket? in the case of gingivitis, the gingival tissue swells, resulting in an increased probing depth
how do you calculate clinical attachment level when the gingival margin covers the CEJ? subtracting the gingival marring level from the probing depth gingival margin is coronal to CEJ, you subtract
what is attached gingiva? extends from base of sulcus to mucogingival junction keratinized so protects alveolar mucosa from bacteria
what is alveolar mucosa non keratinized
how do you measure the width of attached gingiva Measure the total width of the gingiva from the gingival margin to the mucogingival junction (laying probe against tooth) Measure the probing depth (from the gingival margin to the base of the pocket) subtract probing depth from total gingiva
total gingiva for anterior teeth maxillary 3.5-4.5 mm
total gingiva for anterior teeth mandibular 3.3-3.9 mm
total gingiva for premolars maxillary 1.9 mm
total gingiva for premolars mandibular 1.8 mm
where is total gingiva not measured palatal sufaces
what is a probing depth? distance in millimeters from the gingiva to the base of the sulcus or periodontal pocket as measured by the periodontal probe
which sides are usually deeper when probing? mesials and distals
what is class I mobility tooth can be moved up to 1 mm in any direction
what is class II mobility tooth can be moved greater than 1 mm in any direction but is not depressible in the socket
what is class III mobility tooth can be moved in a buccolingual direction and is depressible in socket
what is a class I furcation beginning involvement, concavity of furcation cab be detected with a explorer or probe but it cannot be entered. can't be detected on x-rays
what is a class II furcation clinician can enter the furcation from one aspect with a probe or explorer but cannot penetrate through to the opposite side
what is a class III furcation through and through involvement but the furcation is still covered by soft tissue, definite can see on the X-ray
what is a class IV furcation a through and through furcation involvement that is not covered by soft tissue, clinically it is open and exposed
what does generalized mean? all or nearly all teeth all in one quadrant
what does localized mean? a single tooth a specific group of teeth
what does marginal mean located on free or marginal gingiva may or may not include gingiva
what does papillary mean? papilla only
what does diffuse mean? spread out, dispersed affects gingival margin, attached gingiva and papilla
when it is diffuse it is rarely... generalized
what is stillman's cleft look like? patient cut it looks like floss cut but can't get floss in there
what is McCall's festoon look like? lifesaver around the tooth
what is the mucogingival junction? separates attached gingiva and alveolar mucosa
