what teeth are the most common to see dentinal hypersensitivity? 1st molars and premolars second premolars, canines are second
which arch is it most common to see dentinal hypersensitivity on? maxillary
which nerve fibers are associated with dentinal hypersensitivity? mylinated A fibers
what is the hydrodynamic theory? you have fluid within your dentinal tubule and when you place any stimulus to the outside of that tooth it triggers the fluid within the dentinal tubule to move wither in an outward or inward direction the movement stimulates the odontoblast
what do the dentinal tubules look like in a person who has sensitivity? 8x as many and 2x a wide
what are neural acting agents? directly effect the nerve itself, effect the odontoblast, does not block the stimulus from getting to the odontoblast
what are tubular blocking agents? precipitate that forms on top of the dentinal tubule or travels in the tubule and causes plug
if the patient has a low reaction to pain...they have a what threshold? high pain threshold
if the patient has a high reaction to pain...they have a what threshold? low pain threshold
what are unmylinated C nerve fibers? slow conduction of pain, takes more pain before it is triggered dull aching pain that lingers PULPITIS
What are militated A nerve fibers? fast in conduction, patients feel it immediately, takes little pain before it is triggered, as soon as you remove the stimulus the pain goes away dentin hypersensitivity
what can you NOT use on dentin hypersensitivity patients? sickle scaler, prophy jet, rubber cup polisher
what is dyspnea? difficulty breathing
what are the numbers for COPD? 3rd leading cause of death, 8% adults 14% older adults higher incidence in men than women

what are emphysema sufferers like? pink puffers, thin physique, barrel chested, seldom cough, scanty sputum, severe dyspnea, few respiratory infections
what individuals can you not use nitrous oxide on? severe COPD and emphysema
what can you not use on people with asthma epinephrine
what people can you not use ultrasonic scaler or prophy jet on? chronic bronchitis and emphysema
when is obstruction obvious in chronic bronchitis? inhalation and exhalation
when is obstruction obvious in emphysema? exhalation only
what happens during asthma? constriction of the airways due to bronchial smooth muscle spams
what is intermittent asthma? symptoms less than once per week, brief exacerbations, asymptomatic between exacerbations, nocturnal symptoms less than twice a month
what is mild persistent asthma? symptoms less than once per week but more than once a day exacerbations that affect activity and sleep nocturnal symptoms more than twice a month
what is moderate persistent asthma? daily symptoms, daily use of inhaled short acting beta agonist nocturnal symptoms that happen more than once a week occasional ER visits
what is severe persistent asthma? daily symptoms, frequent (more than 4 times a month) exacerbations and nocturnal asthma symptoms, often hospitalized
what are the causes of iron deficiency anemia? malnutrition or malabsorption, chronic infection, blood loss, alcoholism or pregnancy
what is pernicious anemia? deficiency in vitamin B12, deficiency of intrinsic factor
what are some signs of pernicious anemia? numbness in toes and fingers, CNS involvement like dizziness, confusion, hypotension, dimmed vision, abdominal pain
what is the survival rate of a sickle cell RBC? 10-15 days
what is the normal survival rate of RBC? 90-120 days
what is polycythemia? increased number of RBC, no known cause avoid iron supplements
what is leukemia? malginant neoplasm of immature WBC that multiply uncontrollably and become cancerous
what is hemophilia? low levels or complete absence of blood protein essential for blood clotting
what is hemophilia A? reduced amount of factor VII or 7 most common, X-linked recessive
what is hemophilia B? caused by deficiency of factor IX or 9 X-linked, seen in males more than females
what is von willebrand's disease prolonged bleeding time in the presence of a normal platelet count
blood is how much % plasma fluid and how much % formed elements? 55% plasma fluid and 45% formed elements
of the formed elements how much is erythrocytes and leukocytes? 44% erythrocytes 1% lekocytes
