Pathways Flashcards
What are possible causes of increased mobility
acute or chronic physical trauma occlusal trauma parafuntional habits periodontal disease root fractures Ortho Extension of pulpal disease
Tooth mobility is directly proportional to what
Integrity of the attachment apparatus or
extend of inflammation in the PDL
What is the most plausible dx for a tooth that responds to heat and then is relieved by cold
Necrotic pulp
What determines the vitality of the pulp
intactness and health of the vascular supply, and not the status of the pulpal nerve fibers
With E pulp testing, what are some reasons for false-positive responses
Partial P necrosis
Pt’s high anxiety
Ineffective tooth isolation
Contact with metal restorations
With E pulp testing, what are some reasons for false-negative responses
Calcified obliteration in the root canals
recently traumatized teeth
Immature apex
Drugs that increase pt’s threshold for pain
Poor contact of pulp tester to tooth
What is one of the advantages of using Laser Doppler Flowmetry LDF
Collected data is base on objective findings rather than subjective pt responses.
What is referred pain usually provoked by
Intense stimulation of pulpal C fivers
What five questions must be answered before any endodontic tx
Is the existing problem of dental origin
Are the pulpal tissues within the tooth pathologically involved
Why is the pulpal pathosis present
What is the prognosis
What is the appropriate form of treatment
What are oral manifestations of HIV/AIDS
Candidiasis Kaposi's sarcoma Hairy leukoplakia HSV Herpes Zoster RAU NUP Oral warts trigeminal neuropathy Melanotic pigmentation
What are five inflammatory mediators
Prostaglandins (PGs) Leukotrienes Bradykinin Platelet-activating factor Substance P
What is the reaction in tissue as a result of presence of inflammatory mediators
Pain fivers are directly stimulated or sensitized
Increase in vascular dilation resulting in edema and increase in interstitial tissue pressure
How do glucocorticosteroids reduce the acute inflammatory response
Suppression of: Vasodilation Migration of PMNs Phagocytosis Formation of arachidonic acid thus blocking the COX and lipoxygenase pathways and respective synthesis of PGs and leukotrienes.
What common glucocorticosteroid is used
Methylprednisolone
