What is the objective of nonsurgical periodontal therapy?
|
eliminate or at least suppress the pathologic microorganisms in the subgingival therapy to promote healing and control the infection
|
|
|
A form of antimicrobial agent produced by or obtained from microorganisms that can kill other microorganisms or inhibit their growht; may be a specific for certain organisms or may cover a broad spectrum.
|
antibiotic
|
|
|
Use of specific chemical or pharmaceutical agents for the control or destruction of microorganisms, either systemically or at a specific sites.
|
antimicrobial therapy
|
|
|
The position of the periodontal attached tissue at the base of the sulcus or pocket as measured from a fixed point.
|
attachment
|
|
|
The union of connective tissue or epithelium with a root surface that has been deprived of its original attachment apparatus.
|
new attachment
|
|
|
The reunion of epithelial and connective tissues with root surfaces and bone such as occurs after an incision or injury.
|
reattachment
|
|
|
Available for absorption by the body.
|
bioabsorbable
|
|
|
Susceptible of degradation by biological processes, as by bacterial or other enzymatic action.
|
biodegradable
|
|
|
Tubular instrument placed in a cavity to introduce or withdraw fluid.
|
cannula
|
|
|
Treatment by means of chemical or pharmaceutical agents.
|
chemotherapy
|
|
|
Local delivery of a chemotherapeutic agent to a site-specific area; may be a patch to be worn on the skin or a polymeric fiber.
|
controlled release
|
|
|
A minimally invasive diagnostic procedure used in medicine to examine inaccessible tissues by inserting a fiber-optic tube into the body.
|
endoscopy
|
|
|
Invasion and multiplication of microorganisms in body tissues.
|
infection
|
|
|
Caused by microorganisms that are part of the normal micobiota of the skin, nose, mouth, and intestinal and urogenital tracts.
|
endogenous infection
|
|
|
Caused by organisms acquired from outside the oral cavity or the host.
|
exogenous infection
|
|
|
Occurs in a systemically or locally impaired host; may be highly virulent, but they can cause disease when the host defense is altered.
|
opportunisitc infection
|
|
|
Instrumentation performed after the area has been exposed by tissue removal or the tissue is separated and laid back as a flap.
|
open scaling and root planing
|
|
|
Not responding to usual treatment.
|
refractory
|
|
|
What are the needs of a patient with uncomplicated gingivitis?
|
complete scaling
patient compliance in personal daily biofilm removal |
|
|
What is the effect of scaling a patient with uncomplicated gingivitis?
|
can bring about a reversal of inflammation, and health can be maintained
|
|
|
What are the needs of a patient with early periodontitis?
|
nonsurgical periodontal therapy
continuing routine appts for professional scaling and supervision of the patient's biofilm removal methods |
|
|
What are the needs of a patient with advanced periodontal conditions or patients with poor response to routine therapy?
|
supplemental therapeutic measures
specialized instruments may be required for deep pockets, furcations and complex anatomical features |
|
|
What are the needs of a patient that requires surgical or other advanced periodontal therapy?

standard/ultrasonic tips/inserts used on moderate to high power
sickle scalers and/or periodontal files universal curets gracey curet mini-bladed area-specific and/or Graceys diamond files precision-thin ultrasonic tips/inserts for final polish |
|
|
What is a device developed to visualize below the gingival margin for use during diagnosis and instrumentation for treatment of periodontally diseased root surfaces?
|
endoscope
|
|
|
What are the indications for using an endoscope?
|
during maitneance to detect and remove remaining deep burnished calculus deposits
advanced root therapy for patients unable or unwilling to have recommended surgical procedures |
|
|
What are the advantages of an endoscope?
|
quality of end product
tactile sensitivity patient education in anterior regions where preservation of tissue is necessary when surgical therapy may be contraindicated for the patient |
|
|
The endoscope is good for providing confirmation of clincial findings that might otherwise go undiagnosed or require surgical intervention: what are some examples?
