Each of the following root characteristics provide significant resistance to displacement from traumatic forces EXCEPT one. Which one? - A short, smooth root The mandibular second molar has - Four almost equal roots Which has an oblique ridge (select all that apply.)? -Maxillary first molars, Maxillary second molars Which of the following accurately describe mandibular molars (select all that apply.)? - Crowns are wider mesiodistally than faciolingually, The occlusal groove on the second molar is well established The crowns of the maxillary incisors are wider mesiodistally than labiolingually. The roots of maxillary incisors are oval in cross section. - The first statement is true; the second statement is false. The lingual cusp of maxillary first premolar is longer than facial cusp. This tooth often has two roots, one mesial and one distal. - Both statements are false. Which molar has two buccal grooves? - Mandibular first Teeth with curved roots afford resistance to apical & distal forces but are vulnerable to occlusal forces. Roots with Triangualr cross section are particularly vulnerable to lateral displacement. - Both statements are false. Pain within the root (root pain) can be elicited by which of the following? (select all that apply.)? - Root decay, Root resorption, DehydrationSecondary anatomy refers to anatomical features of second molars and premolars. Tertiary anatomy refers to unique anatomical features of third molars. - The first statement is false; the second statement is true
