Dentin Hypersensitivity to Eating Disorders
| Question | Answer |
|---|---|
| where is the most common site to see dentinal hypersensitivity? | buccal and cervical area of the tooth |
| 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 the numbers for asthma? | 300 million worldwide, affects children 10% adults 6% women more than men |
| what are the etiology of COPD? | smoking #1 etiology pollutants from occupation or environment |
| what are chronic bronchitis sufferers like? | blue bloaters, overweight, chronic productive cough, copious sputum mild dyspnea, frequent respiratory infections, hypoxia |
| 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 |
