Final Part II- Anomalies & Anteriors Flashcards
With tetracycline staining of the teeth, it is an ________ type stain involving mainly which layer of the tooth?
Intrinsic…Dentin
In tetracycline staining, is the STRUCTURE of the teeth compromised?
NO, just a color issue not a functional issure
How is tetracycline staining brought about?
the antibiotic therapy (tetracycline) in FORMATIVE stages of tooth development
Can dental bleaching materials and procedures affect the tetracycline stains?
They have LITTLE success (veneers/crowns the fix)
Which tooth is most likely to be affected by dens-in-dente?

It is a TRAPEZOID…and NEVER a triangle
Perm Max Cent Incisor-~Incisal~ What is the MD width? What about the FL diameter? (all in mm please)

Perm Maxillary Lateral Incisor;;INCISAL aspect» What are the measurements for the MD length and the FL length?

Perm Max LAT incisors
Perm Maxillary Lateral Incisor;;INCISAL aspect»Which direction does the lingual crown outline converge SHARPLY toward?
the lingual…Claro que si!
Perm Maxillary Lateral Incisor;;INCISAL aspect» Which side of the MD bisector does the CREST of the lingual cingulum lie on?
Slightly to the DISTAL of the MD bisector
ALL cinguli on Anterior teeth _______ or point, and are oriented slightly toward the _____ aspect.
incline….Distal
Incisal View of the Perm MANNY Central Incisor: The ___ diameter is greater then the ___ width.
FL greater than the MD width…BOOM BIG CHANGE (first time I’ve seen this on the final)

equidistant
Incisal View of the Perm MANNY Central Incisor: The incisal ridge runs straight across MesialDistally _______ to but slightly ______ to the FL bisector of the crown.
parallel to but slightly LINGUAL
What has more distinct MF and DF line angles: Man Lat Incisors OR Max Lat Incisors? POR QUE??
Mandibular Lateral Incisors BECAUSE of the FLAT incisal 1/3 on the facial surface
Incisal View of the Perm MANNY Central Incisor: The crest of the lingual cinglulum is slightly ______ of the MD bisector.
Distal (just like Maxillary)
Incisal View of the Perm MANNY Central Incisor: The outline of this crown is said to be ________ ________ (hint: why he didn’t put any on our practical)
BILATERALLY SYMMETRICAL
Who has the more prominent anatomical features: Perm Man Lat’s or Perm Max Lat’s?
Perm Max Lat’s have more prominent anatomical features.
Lingual View of a Perm Man LAT….The Lingual Fossa is ______ in shape. It is also _______ and limited primarily to the _____ 1/2 of the crown.
Trapezoidal…..shallow….Incisal 1/2
Lingual View of a Perm Man LAT…. The cingulum is _______ and _______ and not as well delineated.
Rounded and Smooth
Which root aspect of a Perm Man Lateral Incisor has LESS tooth structure: Facial or Lingual?
Lingual Root has LESS tooth structure
Is there a Root surface depression present on the LINGUAL surface of a Perm Man Lateral incisor?
NO!
A DISTAL tour of the Perm MAND Lat Incisor: Can I see the Mesial Marginal ridge from this view?
NO! It is covered by the outline of the Distal Marginal Ridge
A DISTAL tour of the Perm MAND Lat Incisor: The cervical line curves less toward the incisal then on the mesial (normal), but MORE IMPORTANTLY: the crest of the curvature is located slightly on the ______ portion of the tooth!
LINGUAL!!
A DISTAL tour of the Perm MAND Lat Incisor: The root ______ and root ________ are similar to a man central.
root outline and root depression
A DISTAL tour of the Perm MAND Lat Incisor: What can you line the apex of the root up with?
the FL long axis bisector (center of the tooth)
A DISTAL tour of the Perm MAND Lat Incisor: The incisal ridge is located slightly toward the ______ surface when compared to the FL long axis bisector (center) that travels through the root apex.
Lingual…you have to have them sit BEHIND the maxillary teeth on occlusion!
WHASSS UP PERM MAX K9! It is extremely important to a patient’s _____ and overall _______ appearance.
Smile….Aesthetic
WHASSS UP PERM MAX K9! It possesses very _______ and _______ anatomy.
consistant and well-developed
WHASSS UP PERM MAX K9! This tooth seldom has a ________ root.
Bifurcated

“C” (cusp tip to root apex)
HOLLA AT ME PERMANENT MANDIBULAR CANINE: The cusp tip and cusp ridges are _____ to the FL bisector (**this is the same with ALL mandibular anterior incisal ridges, and it makes sense!!)
