MDS PREP

The oral mucosa covering the base of the alveolar bone

1. is normally non-keratinized but can become keratinized in response to

physiological stimulation

2. is closely bound to underlying muscle and bone

3. does not contain elastic fibers

4. merges with the keratinized gingiva at the mucogingival junction

Dental Anatomy Answer: 4

Mandibular premolars differ from maxillary premolars in that, mandibular premolars have all of the following characteristics, except
1. have crowns much more rounded and lingual cusp not so strongly developed.
2. have roots much less flattened mesiodistally and seldom bifurcated
3. they are wider mesiodistally
4. have crowns tilted to the lingual in relation to the long axis of the root

Dental Anatomy Answer: 3

Which of the following is true regarding maxillary molars?
1. Curve inward more sharply from the medial plane on the buccal than do the mandibular molars
2. By their arrangement and design allow room for the powerful masseter muscle.
3. Are set somewhat lingual to the premolars
4. Show a convergence of their buccal surfaces mesially
