Study These Flashcards
A

colophony allergy
asthma hospitalisation
ulcerative gingivitis

24
Q

what are the 2 materials used for fissure sealants?

25
when and where are fissure sealants applied?
all permanent molars after eruption all susceptible pits and fissures where a child is at risk of caries
26
when would you use GI for fissure sealants? how can you apply it?
poor cooperation/ moisture control easy to apply with finger press technique
27
what type of lesions may you want to fissure seal?
initial occlusal and proximal lesions
28
how many times a year can you apply SDF?
2
29
what percentage of SDF do we use?
38%
30
what is SDF licensed for in the UK?
desensitisation
31
what are the indications for the use of SDF?
- Pts at high risk of caries (xerostomia/ severe early childhood caries). - Pre-cooperative child (very young). - Treatment challenged by behavioural or medical conditions. - Pts with several carious lesions that may not be treated in one visit. - Difficult to treat dental carious lesions. - Pts without access to dental care.
32
what are the contraindications of SDF?
silver allergy pain' IP/PA infection; swelling, abscess, fistula unable to isolate tooth
33
how is SDF applied?
microbrush and agitate for 1 min
34
what consent do you have to gain before applying SDF?
pt and parent must be aware the lesion will go dark/ black it stains every thing it touches
35
what do you place before placement of a hall crown? and when?
orthodontic separators 5-7 days prior
36
what material is a hall crown?
stainless steel
37
what is the hall crown filled with for cementation?
GI luting cement
38
what are the indications for a hall crown?
asymptomatic clear band of dentine proximal lesions cavitated or non cavitated occlusal lesions if pt cannot tolerate other treatment
39
what are contraindications of hall crown?
IR or abscess/ infection caries in to pulp arrested caries
40
how long does it take for occlusal equilibration following crown placement?
4-6 weeks
41
what is stepwise caries removal? and does it require LA?
yes LA stage 1 - remove superficial caries and place GI stage 2 (6-12 months later) - access cavity and place permanent restoration there should be an increased distance of pulp to caries
42
when would you use stepwise caries removal?
extensive occlusal or proximal lesions in permanent molars
43
when would you do complete caries removal?
moderate occlusal lesions moderate proximal lesions advanced anterior lesions
44
what is selective caries removal?
leave arrested caries at the base of the cavity and clear the walls
45
when would you use selective caries removal?
moderate occlusal lesions moderate proximal lesions
46
what is site specific prevention?
show parent and child the carious lesion OHI diet advice fluoride varnish monitor if not arrested after 3 months, consider alternative tx
47
when would you do site specific prevention?
initial proximal lesions
48
how would you treat an initial occlusal lesion in a primary tooth?
site specific prevention or fissure sealh
49
how would you treat an advanced occlusal lesion in primary teeth?
selective caries removal or hall crown
50
how would you manage an initial proximal lesion in primary teeth?
site specific prevention or fissure seal
51
how would you manage an advanced proximal lesion in primary teeth ?
selective caries removal or hall crown
52
when can you start taking bitewings?
4 years
53
when do you take bitewings for high risk pts?
every 6 months
54
when do you take bitewings of primary dentition low risk?
every 1 year
55
when do you take bitewings of permanent dentition low risk?
every 2 years
56
how often do you make appointments for high risk caries?
every 3 months
57
how often do you recall low caries risk pts?
6 months
