Test 2 Flashcards
What are the 4 modifying factors of furcation involvement
Anatomic, Supervised neglect, difficult cleansibility, restorations
What are 5 examples for anatomic modifying factors of furcation involvement
Cervical enamel projections, enamel pearls, accessory canals, root anatomy, root trunk length
What factors affect root anatomy 4
Form proximity grooves and concavities bifurcation ridges
exposed roots are more or less sussectable to caries
more
Longer trunks roots are harder to clean but are less or more susceptible to caries
less
Short root trunks are easy to clean but are more or less susceptible to carries
more
Root trunk distances for the facial maxillary molar and Mandibular molar
Facial molar is 4mm long while the mandibular is 3 mm
Root trunk distances for the mesial surfaces of maxillary bicuspid, molar
3mm for maxillary molar
7mm for maxillary bicusbid
Root trunk distances for distal surfaces of maxillary molar and bicusbid
5mm
7mm
What is the lingual distance of a mandibular molar
4mm
Premolars have a good prognoses with furcation involvement because of the root trunk length T of F
false the have a poor prognosis
Bifurcating ridges within the furcations are present 73% of what molars
mandibular and they are convex on both sides
entry of probe for maxillary teeth are from what angles
Mesial palatal, distal and facial right angled.
What type of probe is used for maxillary molars
naber’s probe
Glinkmans classifications go to what number
1-4
What describes Glinkmans class 1 furcation
not evident on radio graph, incipient bone loss
Hamp classification involves 3 classes but are different than the Glinkmans classifications.
false they are the same
Where is the incipient bone loss for class 1
opening of the furcation, detectable upon examination but not by radiograph
Glinkmans class 2 furcation involvement is
partial bone loss, with a culdelsac like appearnce, not through and through and may or may not show up on a radiograph
Class two of glinkmans can either be what or what
deep or shallow, deep may go all the way to the middle and stop at the mesial root
Class 3 glinmans furcation involvement is
through and through and will definitively show up on a radiograph, inter radicular bone is completely absent
Class 4 glinkmans furcations involve a
through and through with a furcation exposure due to gingival recession
Hamp classes go to what number and explain each number
1 2mm
3 through hand through
What is the average width of a currette
1.25
