Question 1: Characteristics of All Incisors from the Proximal Views

Answer:

Wedge-shaped (triangular) outline Bulge greatest in cervical third facially and lingually (cingulum) Lingual outline is "S" CEJ curves incisally Root tapers to apex When present, distal root depression is greater than mesial

Question 2: mandibular central incisors are known for

Answer:

symmetry Question 3: distal proximal height of contour is more cervical than the mesial height of contour

Answer:

maxillary central and lateral incisor mandibular lateral incisor

Question 4: Marginal Ridges of Maxillary Incisors from the Lingual View

Answer:

Maxillary lateral incisor has the distal marginal ridge appear shorter than mesial (more so than on centrals) due to slope of incisal edge shorter toward distal, and distal placement of cingulum

Question 5: Lingual Fossa of Maxillary Incisors from the Lingual View

Answer:

Maxillary laterals more likely to have deeper lingual fossae and pits than centrals Question 6: root is very narrow mesiodistally with mesial and distal root depressions

Answer:

mandibular central and lateral incisor

Question 7: General Similarities of Most Incisors from the Facial View

Answer:

Relatively straight incisal edge Rectangular shape: longer incisocervically than mesiodistally Taper narrower from contact to cementoenamel junction (CEJ) CEJ curves toward apex

Question 8: are more likely to have deeper lingual pits than centrals

Answer:

maxillary incisals

Question 9: incisor crown outline on the distal are

Answer:

convex than on mesial (except on the mandibular central incisors)

Question 10: tooth has the shortes root relative to its crown

Answer:

maxillary central incisor Question 11: incisal edge is positioned more to the lingual of the root axis line

Answer:

mandibular central and lateral incisor

Question 12: Functions of Incisors

Answer:

Cut food Articulate speech Support lips (esthetics) Guide mandible during movement

Question 13: Characteristics of All Incisors EXCEPT Mandibular Centrals from the Facial View [cont.]

Answer:

Distal crown surface is more convex than mesial Mesioincisal corner is sharper than distoincisal Distal contact is located more cervically than on mesial Incisal edges slope cervically to distal

Question 14: root shape maxillary incisors

Answer:

All incisor roots have lingual surfaces that are convex Roots taper narrower toward the lingual

Question 15: incisal crown shapes are

Answer:

rectanguluar, longer incisogingivally than mesiodistally from the facial

Question 16: distal contact arears are more

Answer:

cervical than the mesial Question 17: mesiodistal dimension of the crown is larger than the labiolingual dimension

Answer:

maxillary central and lateral incisors Question 18: mesial angles are more square than distoincisal angels which are obtuse except

Answer:

mandibular central incisors

Question 19: tooth has the largest curvature of the mesial cervical line

Answer:

maxillary central incisor

Question 20: tooth has the narrowest incisor crown (mesioditally)

Answer:

mandibular central incisor

Question 21: Characteristics of All Incisors from the Lingual View

Answer:

Lingual surface narrower (seen best incisally) Marginal ridges converge toward cingulum

Question 22: Incisal Edge of Maxillary Incisors from the Proximal Views

Answer:

Maxillary centrals (from distal view) may have distoincisal corner showing due to distolingual twist of incisal edge (shows better on incisal view)

Question 23: incisal ridge exhibits a distolingual twist

Answer:

maxillary central incisors mandibular lateral incisor

Question 24: crown is the longest incisor crown

Answer:

maxillary incisor crown

Question 25: maxillary and mandibular incisors have

Answer:

• lobes and cingulum

Question 26: tooth has the widest (mesiodistally) incisor crown

Answer:

maxillary central incisor

Question 27: mesial contact arears are in the

Answer:

incisal third

Question 28: Cingulum of Maxillary Incisors from the Lingual View

Answer:

Maxillary central incisor cingulum is more developed and is off center toward the distal (best seen from incisal view); cingulum of lateral incisor is more centered
