Which of the following is true for permanent teeth________________?
Correct answer: D. All of the above
- A. Maxillary roots are inclined distally where as Mandibular roots are inclined mesially
- B. Maxillary molars are buccally inclined and Mandibular molars are inclined lingually
- C. Buccal cusps of lower and lingual cusps of upper are the functional cusp
- D. All of the above
Explanation
The general arrangement is distal inclination of maxillary roots and mesial inclination of mandibular roots, with maxillary posterior teeth positioned buccally and mandibular posterior teeth lingually. The buccal cusps of mandibular teeth and lingual cusps of maxillary teeth are the functional or supporting cusps, so all three statements are intended to be true.
