Fovea palatini represent depressions along course of greater palatine nerve tensor palatini insertion crypts in palatine tonsils orifice of minor palatine salivary glands 3. Saliva which is formed in salivary gland when passes from salivary acini to duct orifices, it undergoes ion exchanges and as a result, saliva becomes hypotonic Hypertonic all of the above isotonic 4. Bartholin’s duct is the name of Lacrimal duct Sublingual duct Submandibular gland Parotid gland 5. If a maxillary 1st molar has a fourth canal it is located in which of the following roots mesiofacial distofacial palatal 4th 6. A maxillary right canine may be distinguished from a maxillary left canine because: Lingually, the cervical line slopes mesially. Labially, the cusp tip is placed distal to a line which bisects the crown and root. The root always curves to the distal in the apical one-third. The distal half of the canine shows more convexity than the mesial half. 7.

Very little time gap between matrix formation and mineralisation is characteristic of Bone Enamel Cementum Dentin 18. When calcospherites fail to fuse during dentin matrix formation the result is formation of Dead tracts Interglobular dentin None of the above Irregular dentin 19. Direction of the enamel rods in the deciduous and permanent teeth is Different at cervical third Different at occlusal and ncisal third None of the above Same throughout 20.
