Periodontology

Chapters 5 and 7

QuestionAnswer
What types of components are in supra and sub calculus? (refer to chart) Inorganic and organic
Hydroxyapatite what percentage id located in the inorganic and organic? 58%-double check
In sub gingival calculus where is the mineral content derived from? GCF
In supragingival calculus where is the mineral content derived from? Saliva
What are locally contributing factors to perio disease? Plaque Bio-film Faulty restorations Overhangs Malpositioned teeth Occlusion Etc.
Which calculus is more mineralized? Sub calculus
What are the color differences between supra and sub? Supragingival calculus: white Subgingival calculus: green, brown, black- color changes due to oxygen availability
What are the main systemic conditions that effect on perio disease? Diabetes
Does having perio worsen or help out the glycemic control of a diabetic-? Worsen severe perio has been shown to worsen this situation
What is the specific nutritional deficiency? What is the name of this deficiency? Vitamin C deficiency also known as scurvy Nutritional deficiency can have any effect on perio disease
can calculus form where there is no plaque is not present No it can not
By itself can calculus cause disease? No
is calculus an attachment mechanism for plaque Yes
does tobacco have any relevance to perio disease Yes
should we discuss about tobacco use- Yes about i.e. decreased healing time etc.
does pellicle have anything to do with attachment- Yes
Do surface irregularities have anything to do with attachment? Yes
Do bacteria penetrate through the cementum? Yes
Different components that make up calculus which one are the primary component? Inorganic
Does perio disease have an influence at all on pregnancy? Premature birth, low birth weight (baby) Gingivitis effects due to hormonal imbalance (mother)
What does the term nosocomial mean? That you acquire an infection or got sick form something you got from the hospital i.e. staph-infection
Which one is locally or systemic that has the ability to shift the microbia more associate to health? Locally; metrondiazonol
Know the antibiotics Refer to chart
Which is the one that inhibits collagenase activity and helps controls disease? Tetracycline
What do the inflammatory inhibitors deal with? Cytokines
Which one is the chip? clorahexadine
Which one is we concerned with resistance? Penicillin
Which one inhibits the spirochetes? metroniazonal
Supra gingival calculus is composed of what? pg. 56 in the old book chapter 5 attachment to the tooth surface Calcium phosphate
Where does most often find supra gingival calculus? By the salivary ducts
How long does it take for plaque to calcify (mineralize)? 2-days up to 50%
Specific in toothpastes etc. What is the specific ingredient in them? pg. 58 anti-calculus toothpastes chapter 5 attachment to the tooth Pyrophosphate
Tetracycline useful in treating periodontal disease because they are concentrated in the gingival fluid; AA is susceptible to tetracycline (AA means actinomycetemcomitans)
helpful in the treatment of aggressive forms of periodontitis; may be helpful in periodontal therapy because it inhibits collagenase activity, thus helping to control the spreading of disease Tetracycline
Metronidazole • treat periodontal disease because of its ability to inhibit several periodontal pathogens including the spirochetes • kills anaerobic bacteria but is not affective against AA • come in a gel form
Penicillins • does not increase attachment • common allergies • periodontal pathogens may become resistant to this
Cephalosporins • no more info
Chlorexidine • disinfectant placed subgingivally as a chip • degrade in 10 days • can still do regular home care • continually releasing antibiotics • called perio chip • increase heal sites 2 mm
Locally Delivered Antibiotics place the drug right at the infection (more beneficial)
Clindamycin • used to control refractory and rapidly progressing periodontitis
Systemic Antibiotics given to the pt. orally or applied topically
Minocycline • form of tetracycline • in a gel form • shown to improve parameter healing in clinical trials
Doxycycline • gel form • shown to improve attachment measures after 3-6 months • improvement of probing depths and attachment levels and bleeding sites • can be place locally • ability to shift microbial more associated with health
Advantages of locally delivered Antibiotics • lower total dose that is required • lower amount of the drug that is present serum • active ingredient is at the site of infection rather than having to be diffused through the entire circulatory system
Inflammatory Inhibitors-Cytokines • Enzymes released by the inflammatory response to plaque • Mediate the destruction of collagen, damaging gingival and periodontal fibers
