Mod 3 Flashcards
What is the first step in the sucessful tx of a furcation
identify its presence and the extent and specific anatomy of the furca
where is furcation more common and severe
in the first molars
are furcations more common in the max. or mand
max
how to proximal furcations appear on a radiograph
small triangular shadows pointing to the furcation on either the mesial or distal surfaces, called furcation arrows
where are max mesial furcations typically located
1/3 of distance from lingual surface and 2/3 distance from buccal
what part of the ultrasonic scaler should you use in a furcation
the rounded back
what are the best ultrasonics to use in a furcation
curved or contra angle slim style insert
what are indications for files
removal of tenacious calc and overhanging amalgams, removing burnished calc
when are perio files contraindicated
-calc that is not tenacious and that is removable with other instrumentation
how is the file adapted to the calc deposit
it is parallel
what are the angles of the files to the shank
90 or 105
what are the 2 classes of files
function working and finishing
which files have cutting edges that are farther apart
working files
what are diamond coated files indicated for
removal of biofilm, light calc and or residual/fine calc
furcations, root depressions and developmental grooves
should a file be used directly on root surfac
no only directly on calc
What kind of strokes should be used
short crushing/fragmenting stroke
when is a perio file used in sequence
- prior to ultrasonic and curet use
- or interchangebly with ultrasonic inserts before curet use
the barnhart 5/6 is a universal curette and is used in the posterior teeth
both statements are true
where are the mini gracey curets used
in deep narrow pockets and furcations
a universal curet has what kind of back
rounded
a sickle scaler has what kind of back and tip
triangular and pointed tip
what is the proper stroke for files
crushing
if a patient has furcation arrows what classifcation of patient would they e
class 2 or 3
mandibular facial furcations can be accessed with
gracey 7/8 ,11/12, 13/14, 15/16
