what is the access cavity flooded with
sodium hypochlorite
what is the SX used for
straight line access to canal orifice
SX file speed and torque
300rpm
2Ncm
what is used to negotiate the canal
08 and 10 flexofiles/ glyde
what is used to verify apical patency and confirm a smooth glide path
10 flexofile
what is used to enhance the glidepath
Proglider
Proglider speed and torque
300rpm
2Ncm
what is used to irrigate canals
sodium hypochlorite
what are the names of the 2 shaping files
S1
S2
what must be done between shaping files
irrigate and recapitulate with size 10 flexofile
how many finishing files are there
F1-F5
what flexofile would you use for apical gauging after the use of F1
20
what flexofile would you use to apical gauge after the use of F2
25
what flexofile would you use to apical gauge after the use of F3
30
Protaper gold finishing files speed and torque
300rpm
4Ncm
Where is the WL measured from
incisal edge to radiographic apex
why do we wish to end canal prep at the AC
avoid overfilling
where would the reproducible reference points be
incisal edge or cusp tip
what is used with flexofiles to negotiate the canal
paste lubricant (glide paste)
what distance should the file end from the apex
0.5-1mm
Apex locator safety checks
switched on a significantly charged.
check function outside mouth - touch metal part of file holder with electrode.
check all the meter indicator bars display light up.
the smooth unobstructed pathway from canal orifice to apex of root
glide path
2 components of glide path
micro glide path
macro glide path
how is the micro glide path established
size 08 and 10 k files to working length
how is the macro glide path established
rotary instrument - proglider
amplitude used with paste lubricant
1mm
what must be the case before canal prep
size 10 file should be loose
what irrigation regime is used at the end of canal prep
3ml NaOCl, 3ml citric acid, 3ml NaOCl
what is the obturation technique used
cold lateral compaction
4 ideal properties of a sealer
no shrinkage on setting
insoluble in tissue fluids
good adaptation/ adhesion to dentine and gutta-percha cone
no water absorption and tooth discoloration
examples of paste lubricants
fileeze
glyde
RC prep
what are the 4 types of irrigants
sodium hypochlorite
10% citric acid
17% EDTA
2% chlorhexidine
how many roots in upper 6
3
name roots of an upper 6
P
MB
DB
which canal in the upper 6 often has 2 canals
MB
how frequently does MB2 occur
73.2%
5 criteria for correct access cavity prep
remove all caries
conserve as much tooth structure as possible
remove all coronal pulp tissue
locate all root orifices
avoid damage to pulpal floor or perforation
