what does topical anesthesia desensitize? gingiva only, does not work on keratinized tissue

how do you apply lollicaine? apply gel to dry mucosa, wait 1 minute can penetrate up to 4 mm
how do you apply oraqix? dispens thin layer at gingival margin wait 30 seconds insert blunt tipped applicator into sub gingival pocket dispense until it is overflowing
what are the 5 cardinal signs of inflammation? redness (erythema), swelling (edema), heat and pain loss of function
what are the significance of gingival assessment: determinate inflammatory and non inflammatory changes formulating treatment plan baseline comparisons for findings and periodontal maintence
what is the acute transient phase for periodontal disease? local vasodilation and increased capillary permeability

what are we looking for in gingival description? color, contour, consistency, texture, location
what does chronic inflammation look like? light to whitish pink (chronic or fibrotic) deeper red or bluish red (cyanotic) pale white (severe disease)
what are the parts of a periodontal assessment? probing, bleeding, clinical attachment level, furcation, mobility, mucogingival involvement
what is suppuration composed of? dead cells, PMN's (polymorphonuclear leukocytes)
what can cause gingival recession mechanical trauma, orthodontic movement, crown margins, dental procedures, destructive inflammatory periodontal disease
what is the most common site for furcations? mandibular molars
what is the measurement for mandibular molar furcations? 3-4 mm from CEJ
What are the spots you can have furcations? mandibular molars, maxillary molars, maxillary first premolars
what are the measurements for maxillary molars 4-5 mm
what are the measurements for maxillary first pre moalrs 6-7 mm
what is a class one furcation? interradicular bone intact no radiographic evidence
what is a class two furcation? probe partially enters furcation (1/3) radiographically visible
what is a class three furcation? furca occluded with gingiva interradicular bone destroyed
what is a class four furcation? furca open and exposed through and through involvement
what is class I movement? slight, up to 1 mm
what is class II movement? moderate, up to 2 mm
what is class III movement? severe greater than 2 mm movement and depressible
what is slight periodontitis? less than 30% boneloss
what is moderate periodontitis? 30-50% bone loss
what is severe periodontitis? more than 50% bone loss
what is scaling? removal of calculus and dental biofilm from the supra gingival and sub gingival exposed tooth surface
what is periodontal debridement? removal of all residual calculus and toxic materials from the root to produce a clean smooth tooth surface
what is root planing? instrumentation of periodontally involved teeth to remove cementum that is rough or contaminated with endotoxins
what are the contraindications for periodontal debridement? lack of motivation for home care teeth with severe perio and mobility pockets depths requiring surgery extreme hypersensitivity anug
What is the number 1 cause of death in the US? myocardial infarction
what is hypertension? persistent elevation of the systolic and diastolic blood pressures above 140
what are the risk factors for gingival inflammation or enlargement? poor home care, changes in hormonal levels, systemic disease, some drugs

what are the advanced signs of hypertension? hemorrhages, enlargement of left ventricle, congestive heart failure, angina pectoris or renal failure
what are the categories of drugs used to prescribe for hypertension diuretics: promote renal excretion sympatholytics: modify nerve activity vasodilators: increases blood vessel size and facilitates blood flow
what is stress reduction protocol? establish effective communication and trust provide patient with sense of control short appointments, morning appointments use tell, show, do let patient know when or if discomfort might be felt use available pain measures
