caries Flashcards
what teeth are most likely to experience caries in the primary dentition
molars and upper anteriors
in the mixed dentition stage is carries more likely in upper or lower 6s
lower 6s more likely to experience caries
what is an example of a space maintainer should a primary tooth be extracted early
band and loop
sequence of treatment for deciduous teeth - least invasive to most invasive (6)
fissure sealants
preventative restorations
simple fillings
fillings requiring LA
pulpotomy/pulpectomy
extraction
what is the ideal time to extract 1st permanent molars
start of calcification of bifurcation of lower 7s
what is TETS
temporary elective tooth separation
diagnostic aid for identifying interproximal lesions
orthodontic separator placed between teeth and pt returns in 1 week to allow surfaces to be inspected
what is silver diamine fluoride and what are the pros and cons
liquid containing silver (kills bacteria) and fluoride (aids remineralisation) that is used on decayed teeth to halt/ slow progression of caries
pros: effective, little co-operation required, no drills
cons - aesthetics (decay stained black)
how is silver diamine fluoride applied
petroleum jelly should be applied to lips and gums prior to application
dry teeth - wool and air
place SDF on for 1-3 mins
dry teeth again
minor risks associated with general anaesthetic
(side effects)
pain , headaches, drowsyness, upset, nausea, future anxiety about treatment.
who can consent for children
mother
father if married to mother at time of conception
unmarried father if named on birth certificate
adoptive parents (legal adoptions)
legally appointed welfare guardian
local authority designated to care
Can foster parents consent to a childs treatment
no - foster parents do not automatically gain parental responsibility
how does fluoride prevent caries
promotes remineralisation at plaque/tooth interface
newly formed fluoroapatite less susceptible to demineralisation
how does duraphat fluoride varnish work
varnish is capable of sustained contact as it hardens when it comes into contact with saliva
Created calcium fluoride deposits which are capable of fluoride release over a period of time
acidulated mouthrinses how do they work
low pH mouthrinses
- partially demineralised crystals act as nucleators for fluoride ions
fluoride ions are adsorbed onto crystal surface
this attracts calcium phosphate ions which drive remineralisation
this forms fluoro and hydroxy apatite which are less soluble
how much fluoride would have to be ingested daily for fluorosis to become a risk
0.1mg fluoride per kilo daily
e.g 1mg a day for a one year old
