10

WHat happens with residual ridged after teeth have been removed

they are in a continual process of remodeling

11

26

How do the tissues react to dentures?

-another mouth may have normal keratinization

27

What are factors that influence the mucosa

-wearing denture constantly
-xerostomia
-fit and occlusion of denture

28

What is the effect of xerostomia in denture wear

diminished salivary flow can influence tissue lubrication

29

Why is lubrication important

saliva is needed for protection against frictional irritaion by the denture

30

why is saliva important in denture retention

helps create suction of the denture

31

How does the tactile sense change in a denture wearing patient?

-sensitivity diminished to small objects in mouth
-proprioception is lost due to abscence of PDL

32

How does taste change in denture wearing patients

food has a different taste, taste buds of palate are covered, biofilm on dentures can alter taste

33

What do we do with a denture patient?

do and intra and extra exam to look for mucosal leisons because they are asymptomatic

34

What are the principal causes of leisons under dentures?

-ill fitting dentures
-inadequate OH
-continuous wearing of dentures
-

35

Why do ill fitting dentures cause leisons

-tissue changes occur over time
-pt may not been informed of having regular exam of dentures and mucosa

36

why does inadequate OH cause leisions

-dentures and mucosa need daily care
-denures can accumulate heavy biofilm or calculus that may irriate mucosa, cause infection and inflammation

37

Why does continuous wearing of dentures cause leisons

-mucosa needs rest
-allows tissue to recover in its natural environment

38

What are contributing factors of inflammatory leisons

-denture trauma from fit occlusion or habits
-OH
-chemotoxic effect from cleaners
-allergy to denture base
-pt self treatment
-continuous wear

39

What is another name for localized inflammation

sore spots

40

What is the appearance of localized inflammation

red, inflamed, ulcerated

41

waht are contributing factors to a sore spot

45

are denture wearers aware of they have candida albicans
