periodontology the real one Flashcards
gingiva
cementum
periodontal ligament
alveolar bone
all four combine to make what
tissues of the periodontium
the ………………. is the specialized tissues that both surround and support the teeth, maintaining them in the maxillary and mandibular bones.
periodontium
situated, performed, or occurring beneath the gums and especially between the gums and the basal part of the crowns of the teeth : best describes what
subgingival
Above the gingiva; used in reference to the location of dental restorations, bacterial plaque, or calculus on the tooth. It is often contrasted with subgingival, the gingival margin being the reference point: best describes what
supragingival
forming or belonging to a bottom layer or base.: best desctribes what
basal
…………………is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF)
calculus
where are the greates accumulation of calculus found
greatest accumulation of calculus found on the lower anterior teeth. The anterior teeth are directly above the sublingual gland, where they are in constant contact with saliva
aswell as the upper molars
which would cause more consequences
supra or sub gingival calculus
subgingival
why is plaque considered a retentive factor
Calculus Acts as a rough surface which encourages further plaque accumulation
what colour does sub gingival calculus appear as
dark green - black
what is a cross calculus probe used for
detecting subgingival calculus
generated from piezo-electricity or magnetostriction
which scaler has this feature
ultrasonic
generated from passage of compressed air.
which scaler uses this feature
sonic
what biophysical effect does the ultrasonic scalers have
the vibrating tip damages the bacterial cell membrane
- Vibrating micro-bubbles form, expand to several times their original size, become unstable and violently collapse
- Before collapsing, internal bubble temperature and pressure increase
- Bubble collapse is associated with a shock wave which results in deposit removal and damages bacterial cells
are examples of what
cavitation of the ultransonic scaler
ultransonic scalers generate aerosols. so what following should be avoided when using them on pateints.
- Avoid using on patients with TB, throat, & respiratory infections.
- Avoid using on patients with …especially on the open clinic.
- Avoid if patient cannot tolerate high volume aspiration.
