Q

why should you not wear the denture if you are treating candida albicans infection***

Q

candida-associated stomatitis SYSTEMIC ETIOLOGICAL FACTORS

Study These Flashcards
A
  • old age
  • diabetes mellitus
  • nutritional deficiencies
  • malignancies
  • immunosuppression
  • corticosteroids
24
Q

lesions associated with candida-associated stomatitis

Study These Flashcards
A
  • diffuse atrophic glossitis
  • median rhomboid glossitis
  • ANGULAR CHEILITIS (S. AUREUS)
  • erythema of soft palate
25
candida and s aureus
- symbiotic relationship | - usually a MIXED infection
26
how do you know if it is allergy or candida
-allergy happens very soon
27
prevention and treatment of candida
- correction of ill-fitting denture: adjust and fabricate a new denture - improve oral and denture hygiene - antifungal therapy
28
common antifungal topical treatment
nystatin
29
flabby ridge
- fibrous tissue replaces bone - usually anterior maxilla - poor support for denture - removal vs. special impression techniques
30
burning mouth syndrome
- burning sensation of tissues in contact with dentures | - usually pts: >50 yrs, female, complete dentures
31
residual ridge reduction loss in 1st year (vertical)**
- 2-3 mm max - 4-5 mm mand - 0.1-0.2mm annually after
32
traumatic ulcers or sore spots usually arise as a result of
over-extended denture flanges or errors in occlusion
33
how to fix traumatic ulcer
use thompson colour to mark it, press denture on it, relieve area on denture
34
what happens if you dont treat traumatic ulcer
denture irritation hyperplasia
35
what is violated with cheek biting due to posterior denture teeth
neutral zone concept (too far buccally)
36
denture irritation hyperplasia is a result of
chronic low-grade trauma | -unstable dentures or overextended denture flange
37
in denture irritation hyperplasia, the flange extends into
mucosal fold
38
what is present in type 3 stomatitis that isnt in type 1 or 2
granular, inflammatory hyperplasia
39
pinpoint hyperemia
type 1 stomatitis
40
erythema of the entire mucosa in contact with denture
type 2 stomatitis
41
higher prevalence of denture stomatitis in
maxillary dentures
42
diagnosis of candida associated denture stomatitis
finding mycelia or pseudohyphae in direct smear or isolation of species in high numbers
43
primary source of the candida stomatitis infection is
candida adhering to fitting surface of DENTURE (NOT MUCOSA!)
44
direct predisposing factor for candida stomatitis
presence of dentures
45
treatment for candida or angular cheilitis
-antifungal therapy with correct prostho management and plaque control
46
other major predisposing factors for candida stomatitis
- unclean dentures | - poor oral hygiene
47
most important preventive measure for candida stomatitis
- oral and denture hygiene | - correct denture-wearing habits
48
when should you be using antifungal agents
- after diagnosis - pt has burning sensations - spreading - risk of systemic infection
49
keep dentures in what at night
disinfectant solution of 0.2 to 2.0 % chlorhexidine
50
cause of flabby ridge
- excessive occlusal loading | - unstable occlusal relationships
51
kelly's syndrome
flabby ridge where complete upper denture and anterior mand teeth remain
52
RRR is important in thin cortical bone areas such as
- max: buccal and labial parts | - mand: lingual parts
53
strong association between skeletal bone density and
bone density of mandible (mandible is also affected by osteoporosis)
54
what happens to muscles and bite force
- reduced bite force | - atrophy of masticatory muscles
55
one thing that improves mastication and forces
implants
56
4 facted related to diet and nutrition
- oral health and mastication - systemic health - SES - dietary habits
