Perio and Instrumentation Flashcards
Describe the gingiva in an health patient.
Color: pink
Firm and resilient
Stippled
Scalloped marginal gingiva
knife edge and pointed falls into embrasure spaces
No bleeding upon probing
sulcus: 1-3mm
JE firmly attached to the tooth by hemidesmosomes
Alveolar bone: 2-3mm aprical to the base of the JE
what is gingivits?
Nonspecific inflammatory response/reaction
reversible
What are the common clinical signs of plaque-inducd gingivitis?
Erythema
Edema
Bleeding
Tenderness
Enlargement
What conditions can exacerbated plaque induced gingivitis?
Hyperglycemia- (gingivitis consistent in children with poorly controlled type 1 diabetes)
Leukemia ( bleeding due to thrombocytopenia and clotting deficiencies)
Smoking
Malnutrition ( depletion of plasma ascorbic acid)
Periodontitits is a chronic multifactorial inflammatory disease associated with?
plaque
progressive distruction of the tooth supporting structures
CAL
alveolar bone loss
presence of pocketing and bleeding
What is peri-implant health?
An absence of visual signs of inflammation and bleeding on probing
What is the difference between peri-implant mucositis and peri-implantitis?
Mucositis is bleeding on prob and visual signs of inflmmation
implantitis- is bleeding, inflammation and loss of supporting bone.
List and define the different types of pockets.
- Pseudopocket: gingival inflammation without loss of attachement.
- Suprabony pocket: base of the pocket is above the alveolar crest: Horizontal bone loss
- Infrabony pocket: Base of the pocket is below the alveolar crest. Vertical bone loss
What are the different types of tooth mobility ?
Class I- 1mm horizontal F-L direction
Class II 1-2mm horizontal F-L direction
Class III greater than 2mm horizontal and or vertical depression
Ankylosis is?
fusion of the enamel, dentin, root cementum with adjacent alveolar bone.
Mostly in deciduous teeth, creats a hollow sound
Impaction is?
tooth positioned against another structure
List and discribe the different types of instrument shanks.
Functional shank- between working end and hanlde
Terminal (Lower) shank - closed to the working end
Simple- has only one bend
Complex- multiple bends: Posterior teeth
Sickle scalers have a triangular cross-sectional shape and have a pointed back and tip.
Used supragingivally
True
Curretts have a semi-circular cross-sectional shape and have a rounded back and toe
Used both sub and supra
True
What are some contraindications for power drivien scaling instruments?
Respirtory diseases, COPD asthma or immunocompromised patients
communicable diseases such as tuberculosis that spreads through aerosol.
skeletal injuries (cerebral palsy)
porcelain or composit restoration
demineralized areas
newly erupted teeth
old pacemakers
