27
what is a hypofunction unstimulated salivary flow
less than .1 ml/min
28
what is a health pH of the mouth
6.7 to 7.4
29
what is an abnormal ph of the mouth
5.5 to 4.5 acidic
30
what is the normal amt of saliva production per day
1 to 1.5 liters
31
what are some prescription meds used in drymouth tx
pilocarpine, fluorides
32
what are some OTC products used in tx of dry mouth
-saliva substitutes -xylitol gums and rinses sonic and ultrasonic tb power toothbrushes
33
what is dentinal hypersensitivity
an exaggerated response to a sensory stimulus
34
in the US how many people have dentinal hypersensitivity
one in five
35
what kinds of things will be ruled out in a differential diagnosis for determining a pt has dentinal hypersensitivity
endo, cracked tooth, fractured restoration, malformations of enamel, sinusitis, caries
36
what is the pain like in a pt with dentinal hypersensitivity
mild to extreme pain short, sharp responds to stimuli
37
what are the 4 kinds of stimuli
evaporative, thermal, tactile, osmotic
38
what is evaporative stimuli
breathing, suction, drying teeth
39
what is osmotic stimuli
OJ, lemon juice, high sugar content
40
what are the two most common age ranges for dentinal hypersensitivity
20-30 and 40-50 (recession)
41
the more _______exposed the greater the degree of sensitivity
tubules
42
what is the most common cause of dentinal hypersensitivity
toothbrush abrasion
43
what are other etiologys of dential hypersensitivity
inadequate attached gingiva, perio disease/surgery, eating disorders, erosion caused by diet, RX, bruxism, abfraction, attrition, prominent teeth
44
what are the types of mechanical stimuli that cause hypersensitivity
toothbrush, instrumentation, clasps from partials, oral habits (toothpicks fingernails)
45
what are the types of thermal stimuli
air, food, drinks
46
what are the types of chemical stimuli
foods(wine, citrus, apple juice) | swimmers (chloriine)
47
what kind of stimuli is bleaching
chemical
48
the higher the percent of hydrogen peroxide in the bleach the ________ the chance of sensitivty
greater
49
what is the hydrodynamic theory*
fluid flow is disturbed by stimuli, and the osmotic changes of the fluid stimulate the nerve in the more pulpal portions of the dentin which causes pain
50
what kind of desensitizing mechanisms are there
nerve desensitization, protein precipitating agents, tubule occlusion, physical, laser
51
what is the mechanism of action of potassium nitrate
penetrated through tubules to the nerve and depolarizes it and prevents repolarization
52
what are prodcuts that have potassium nitrate
crest sensitivity, sensodyne max strength and proenamel, colgate senstivit
53
what are protein precipitating agents
fluorides
54
what is the mechanism of action of fluorides
group together to for blockage in tubules
55
what are examples of products with stannous fluoride
gel-kam, dentin bloc, omni, crest pro-health
56
what are examples of products with sodium fluoride
prevident
57
what can be used to seal tubules
dentin sealer without acid etch, precpitates and seals (bonding agent)
58
what are some products that provide tubule occlusion
gluma, quell sensitivity, ACT
59
what are 2 physical ways to help dentinal sensitivity
- periosurgery (conn. tissue grafting) | - restorations (composite, glass ionomer, crown)
60
Which laser is used in tx of hypersensitivity and how does it work
the Nd:YAG, fuses dentinal tubules
61
can senstivity improve with spontaneous remission
yes 20 to 40% do
62
what is demineralization
occurs almost immediately when we eat or drink fermentable carbs which get into the plaque and the bacteria produces acid which destroys minerals of the enamel
63
how does remineralization work
- calcium and phosphate penetrate into enamel and crystalize which fill in the space left by demineralization
64
what does fl2 do in remineralization
it a acts as a catalyst to move calcium phosphate more quickly in to the enamel and improves the quality of the crystal
65
what is amorphous calcium phosphate (ACP)
calcium and phosphor salts
66
what is ACP found in
arm and hammer toothpaste, enamel pro prophy paste
67
what is Recaldent
CCP-ACP | casien phosphopeptisdes and amorphous calcium phosphate
68
what does the CCP do
stablilizes the calcium phosphate and increases the level in dental plaque and saliva
69
who should you not use Recaldent on
pts with milk allergies
70
what are examples of recaldent products
MI Paste, trident white gum
71

patented ingredient for plaque control
72
what is the microdent product
control rx
73
What are the products in Novamin
bioactive glass compound made from calcium, phosphate, silica and sodium
