1. A primitive tooth form having a single conical crown and a single root is called heterodont acrodont haplodont thecodont 2. The class of low molecular weight calcium binding proteins seen predominantly in developing enamel are Tuftelin Ameloplakin Amelogenin Enamelin 3. A maxillary right canine may be distinguished from a maxillary left canine because: The distal half of the canine shows more convexity than the mesial half. The root always curves to the distal in the apical one-third. Lingually, the cervical line slopes mesially. Labially, the cusp tip is placed distal to a line which bisects the crown and root. 4. neonatal line is an accentuation of Hunter schreger bands Perikymata prominent DE junnction striae of Retzius 5.

Bartholin’s duct is the name of Sublingual duct Parotid gland Submandibular gland Lacrimal duct 14. Supporting cells of taste buds are called as Taste cells Acini Sustenticular cells Von ebner cells 15. The lingual extension of dental lamina is known as Mandibular lamina Successional lamina Maxillary lamina Mental lamina 16. according to recent research, following is true about of pattern of enamel prism demineraliation tail is more resistant to dissolution than head both head and tails are equally resistant to dissolution both head and tails are equally susceptible to dissolution head is more resistant to dissolution than tail 17.
