From the list of characteristics below, choose the attributes that apply to the labial aspect of MAX lateral incisors (Hint, not all answers will be used) a. more convex mesial outline than the MAX centrals b.

Has a more rounded distal outline than that of a MAX central e. exhibits the least amount of rounding of any incisor f. usually has 2 mamelons g. has a CEJ that curves in a regular arc incisally. h. has a labial surface more convex than a MAX central i. has a height of contour in the cervical third. a, b, d, f, h, i 12. The tooth with the most rounded incisal angle in the arch is the: Max Lateral Incisor 13. T or F: _____ The mesioincisal angle of a MAX lateral incisor is more rounded than its MAX central counterpart, and is also more rounded than its own distoincisal angle. FALSE (the distoincisal angle is more rounded, not the mesioincisal.) 14. T or F :_____Labial developmental depressions and imbrication lines are not present on MAX laterals. FALSE (They are present, but less pronounced) 15. T or F :_____ From a labial aspect of a MAX lateral, the mesial outline bears a close resemblance to the Central. true 16. From a lingual aspect, a MAX lateral’s CEJ curves apically but is offset towards the _____________. Distal 17. List at least three characteristics of the labial view of a MAX lateral that sets it apart from the larger central incisor: more prominent mesial and distal marginal ridges) (more prominent cingulum); (deeper lingual fossa) 18. A ____ is more commonly found on the lingual surface of a MAX lateral incisor than that of a central. A linguogingival groove 19. JEOPARDY QUESTION: “Commonly found near the center of the linguogingival groove of a MAX lateral, this feature could be a potential site for caries to begin.”_____? “What is a lingual pit?” 20. Name two grooves that commonly appear on the lingual surfaces of MAX lateral incisors. linguogingival Groove; Linguogingival fissure 21. JEOPARDY QUESITON: “Extending in a distal and cervical direction, this vertical feature usually originates in the lingual pit of a MAX lateral incisor.” _____? What is a linguogingival groove? 22. The linguogingival groove on a MAX lateral runs in a roughly ______________ direction. Horizontal 23. The linguogingival fissure of a MAX lateral runs in a roughly ____________ direction. Vertical 24. T or F: _____ On the lingual surface of a MAX lateral, the height of contour is associated with the greatest curvature of the cingulum in the cervical third. True 25. From a mesial aspect, a MAX lateral incisor: a. is similar to that of a MAX central, but with lessened dimensions. b. has a contact area similarly shaped to that of a MAX central c. has a cervical line exhibiting less depth of curvature than it does on the mesial of the central. d. all of the above. d. all of the above. 26.T or F: _____ The distal surface is smaller and convex in all dimensions from the mesial surface. True 27. T or F: _____The distal contact of a MAX lateral; when compared to the mesial contact, will appear smaller and more gingival. True 28. T or F: _____ The CEJ on the distal aspect of a MAX lateral shows more incisal curvature than it does on the mesial. True 29. Name three features of a MAX lateral incisor that would help you distinguish it from a central. (Incisally, it can have a more rhomboidal shape. Similar to a Canine) ; (The lateral will have a more prominent cingulum); (From an incisal view, a MAX lateral will exhibit more facial convexity). 30. T or F: _____ The root of a lateral incisor is a single root, and is wider labiolingually than mesiodistally. True 31. T or F: _____ In comparison to the central, the root of a MAX lateral incisor appears to be “longer” in relation the sizes of the crowns. True 32. T or F: _____ The root of a MAX lateral is the same length or slightly shorter than that of a MAX central. True 33. T or F: _____ The apex of the root of a MAX Lateral is more blunted than that of a MAX central. 33. T or F: _____ The apex of the root of a MAX Lateral is more blunted than that of a MAX central. 34. Looking at the root of a MAX lateral from a cross section, it will appear to have a somewhat ____ shape. Ovoid 35.
