Question Answer
Gingivitis 1. first stage of periodontal disease. 2. inflammation of gingival tissues. 3. Only affects the gingivae. 4. Toxins from the bacteria provoke an inflammatory response. 5. reversible - carry out effective OH
Clinical signs of gingivitis 1. Bleeding 2. Halitosis 3. Redness 4. Spongy & glossy gingivae 5. Swelling 6. False Pocketing
Treatment for gingivitis > Scale & Polish (dentist cleans false pockets) > Plaque control via OH (teaching patient by giving advise) > Correction of tooth relationships (extracting or adjusting occlusion) > Correction of appliance
Name 6 immuno compromised patients. Pregnant diabetes HIV Smoking, Age & Stress
Why does sucrose encourage plaque formation? When sugar (sucrose) is on the tooth surface, bacteria will attach and plaque will form.
What bacteria is present in plaque 3-8 hours? Cocci, Bacilli, Streptococus mutans
Bacteria present in plaque after 7 days Spirochetes
when a question asks for clinical signs this means? what you can see..
Clinical signs specific to periodontitis > Gingival recession > Bone resorption (loss) > True periodontal pocketing (total destruction of supporting structures) > Tooth mobility > Drifting
what happens if gingivitis is not treated? Microbes affect deeper tissue. This includes periodontal ligament, cementum & alveolar bone.
What is a furcation lesion? Exposed bifurcation/ Trifurcation area that can be accessed by a periodontal probe. cant necessarily be seen.
Causes of periodontitis poor OH Calculus Caries Lip apart posture Gingival recession
What is calculus? * Hard mineralized dental plaque * sticks to teeth, restorations & appliances * 70% in organic salts * 30% micro organisms & organic material *contains calcium & phosphate *calculus makes effective OH impossible
supra-gingival ABOVE gingival margin. colour - white or pale yellow. staining sources - tabacco tar, food pigments. Common teeth - buccal upper molar & lingual lower anterior. Soft & easy to remove with scaler
Reason for supra-gingival calculus occurring on certain teeth. Salivary glands open into the mouth in these areas.
Sub-gingival BELOW gingival margin in periodontal pockets. Colour - Dark/ brown (spread evenly allover the mouth) Cause - breakdown products of blood form the ulcerated pocket epithelium.
what happens in Sub-gingival calculus? A small discreet deposit form a band around the tooth and demineralization occurs. The calculus is hard and difficult to remove.
False pocket enlarged gingival crevice Only affects gingivae if gingivitis is ignored and plaque is not removes, swelling will occur and this will create the illusion of a pocket. Food debris gets caught.
Pocket formation (true pocket) Microbes from plaque penetrate deeper tissue detaching the gingivae from the tooth and causing destruction of periodontal ligament and alveolar bone.
Gingival recession Gingivae becomes agitates due to the toxins and moves away. This detaches the gingivae from the tooth. When this happens roots are exposed and are visible clinically.
Bone resorption (loss)
