what are the 4 stages of minimally invasive dentistry
- Recognition
- Rejuvenate
- Restore
- Review
What is recognition as a stage of minimally invasive dentistry
early identification and assessment of potential caries risk factors
What is rejuvenate as a stage of minimally invasive dentistry
eliminate or minimise caries risk factors (OH instructions, diet changes, fluoride exposure)
What is restore as a stage of minimally invasive dentistry
arrest and reverse incipient lesions, when cavitation is present, conservation caries removal is carried out - using fluoride or CPP ACP
What is review as a stage of minimally invasive dentistry
risk based recall - depends on caries susceptibility , allow for monitoring disease
What are the 5 Rs
review, refurbish, reseal, restore, replace
what is the function of povidone iodine
- antibacterial, antifungal and antiviral properties
- intraoral formulations include mouthwash and gargle
- povidone iodine should not be used during pregnant or lactation because it can cause hypothyroidism in the neonate
what are principles of minimal intervention
- disease risk assessment and early caries diagnosis
- classification of caries depth and progression using radiographs
- reduction of cariogenic bacteria to decrease the risk of further demineralisation and cavitation
- arresting of active lesions
- remineralization and monitoring of non cavitated arrested lesions
- avoid removal of tooth structure in excess to absolutely required to restore to their normal conditions
what is the fluoride concentration in tooth mouse plus
900ppm
What is chlorohexidine mechanism of function
chlorohexidine is bactericidal and fungicidal and has activity against some viruses
Chlorohexidine disrupts bacterial cell membrane causing bacteria death
What would long term use of chlorohexidine cause
- soft tissue irritation
- mouth burning
- intra oral staining of soft mucosa, buccal mucosa, lining of dental restorations
- altered taste
- increased calculus
- interrupt wound healing
What is the prescription of chlorohexidine for long term use (>2 weeks)
0.12%
What is the prescription for chlorohexidine for short term use <2 weeks
0.2%
is chlorhexidine inactivated by sodium lauryl sulfate used in standard toothpaste
No
Where in the brain do the neurons of the corticospinal tract originate from
primary motor cortex
Where do the upper motor neurons of the corticospinal tract decussate
medulla oblangata
What are the key principles of motivational interviewing
- express empathy for patient’s behaviour change dilemma
- develop the discrepancy - between how they currently behave and how they would like to behave
- roll with resistance - avoid counter arguments
- support self efficacy - encouragement
what are the effects of C-reactive protein
Produced by the liver during acute phase inflammation
function:
-enhancing phagocytosis - opsonization
activating the complement system
inflammation marker (releasing pro inflammatory cytokines)
what is the function of corticosteroids
reduce capillary permeability
Affect leukocytes - suppression of immune cells
affect production of prostaglandins - block production
influence activity of transcription factors e.g. NFkB - turning down the expression of pro inflammatory genes and increasing expression of anti inflammatory genes
blocks phospholipase A2 (PLA2)
what is phospholipase A2 (PLA2)
enzyme which releases arachidonic acid which is a precursor for
- prostaglandins
- leukotrienes
- thromboxanes
initiating the production of key inflammatory mediators
what clotting factors require vitamin K
