Q

(November 2009) definition of MI

A
  • philosophy for whole of life management of oral environment
  • comprehensive, personalized approach to diagnosis and management of oral disease and the factors which influence those diseases
  • means for empowering patient with knowledge and skills to reduce their ongoing burden of disease

Q

ICDAS: 6 stages in the carious process

A

Code 0 = sound
Code 1 = first visual change in enamel
Code 2 = distinct visual change in enamel
Code 3 = localized enamel breakdown
Code 4 = underlying dark shadow from dentin
Code 5 = distinct cavity with visible dentin
Code 6 = extensive distinct cavity with visible dentin

Q

focus of minimal intervention dentistry philosophy

Study These Flashcards
A
  • disease prevention
  • diagnosis at earliest timepoint
23
Q

levels of prevention: primary

Study These Flashcards
A

prevent initiation of disease by addressing causal factors

24
Q

levels of prevention: secondary

Study These Flashcards
A

find disease early and arrest its progression

25
levels of prevention: tertiary
limit disability; repair diseased tissue and replace lost, missing or diseased tissue
26
primary prevention: dental caries
- mechanical plaque control - diet modification - lifestyle changes - systemic and topical fluorides - chlorhexidine - xylitol and sugar substitutes - sealants - pH elevation using bicarbonate - culture-based tests for cariogenic bacteria
27
secondary prevention: dental caries
- clinical examination for dental caries (blunt probes, magnification) - intra-oral cameras - bitewing radiographs - drying teeth to identify early carious lesions (ICDAS)
28
tertiary prevention: dental caries
- tooth restoration - atraumatic restorative technique, air abrasion, chemomechanical caries removal, lasers, ultrasonics, and micro-preparation burs - ozone - photo-activated disinfection
29
primary prevention: dental erosion
- dentally safe drinks - diet modification - lifestyle changes - fluoride - recaldent
30
secondary prevention: dental erosion
- clinical assessment of erosive tooth wear and sensitivity related to dental erosion - in-office and at-home application of remineralizing and desensitizing agents
31
tertiary prevention: dental erosion
- tooth restoration with conservative adhesive - intracoronal or extracoronal restorations
32
sample methods for modifying dental plaque biofilm
- Recaldent - xylitol - chlorhexidine - pH elevation using urea or bicarbonate
33
enhancements to conventional radiography
- automated image analysis - subtraction radiography - use of contrast media to enhance detection of proximal cavitations
34
current & emerging technologies - primary prevention: dental caries
- tooth surface protection - plaque fermentation tests - salivary tests for physico-chemical properties - salivary tests for cariogenic bacteria - Recaldent - light-activated fluoride - biofilm modification using ecological therapies
35
current & emerging technologies - secondary prevention: dental caries
- subtraction radiography - digital image analysis - contrast-enhanced radiography for proximal cavitations - light-induced fluorescence (QLF) assessment of surface mineral changes - laser fluorescence detection of incipient and occult occlusal and proximal lesions - fiber optical transillumination - optical coherence tomography - impedance detection of mineral loss - biologically active tooth coatings - internal remineraliation - lesion reversal using Recaldent
36
current & emerging technologies - primary prevention: dental erosion
- saliva testing - modification of erosive foods and drinks - therapeutic sugar-free chewing gums - light-activated fluoride treatments - surface-coatings of teeth to increase acid resistance using adhesive resin or laser deposited or laser-sintered technologies
37
current & emerging technologies - secondary prevention: dental erosion
- physical methods for assessing tooth wear and mineral loss at chairside (i.e. smart sensor coatings indicating mineral loss or gain) - light-induced fluorescence (QLF) assessment of surface mineral changes - rapidly acting desensitizing and remineralizing agents - sacrificial surface coatings for at risk tooth surfaces
38
natural progression of proximal caries
1. molar and premolar regions 2. maxillary anterior teeth 3. mandibular anterior teeth
39
can be used to track mineral loss and mineral gain
light-induced fluorescence
40
methods of digitally enhanced optical imaging
- digitally enhanced fiber optical transillumination (DiFOTI) - optical coherence tomography (OCT)
41
chemical conversion of apatities to fluoroapatites if fluoride is present at the same time as laser or other intense light is applied
photonic conversion
42
combined with Recaldent in more recent developments for rapid reversal of white spot of lesions
fluoride
