Across
  1. 1. The curvature that represents the movement of odontoblasts cells toward the pulp during dentinogenesis.
  2. 3. Tubules filled with mineral, and the dentin appears translucent. This is a consequence of aging and is seen most often in the root. The dentin is made less porous as a consequence.
  3. 7. minor curvatures along the length of dentinal tubules that represent the daily movement of odontoblasts during dentinogenesis of primary & secondary dentiseen along the length of the tubules. This may reflect daily changes in the movement of the odontoblasts.
  4. 9. It is about 2-6μm wide unmineralized zone between the mineralized dentin and odontoblasts
  5. 14. Areas of unmineralised or hypomineralised dentin where fusion of matrix is incomplete.
  6. 16. A hereditary defect of dentin formation characterized by a translucent or opalescent color of the teeth,
  7. 20. the scalloped interface between the dentin & enamel
  8. 22. role in mineralisation. Found in predentin & D.
  9. 24. hydroxyapatite-containing, membrane-enclosed vesicles secreted by odontoblasts, osteoblasts, and some chondrocytes; believed toserve as nucleation centers for the mineralization process in dentin, bone, and calcified cartilage
  10. 25. only in deciduous teeth & 1st permanent molar teeth
  11. 27. it is the active binding of calcium phosphate complexes at the nucleation site in the matrix.
  12. 28. It is a line, between prenatal dentin & postnatal dentin,
  13. 30. refers to dentin formed during the development of the tooth
  14. 32. Globular masses of mineralization matrix form and fuse with each other in the mineralization of circumpulpal dentin.
  15. 34. induce the production of tertiary D.
  16. 36. These are areas of dentin which no longer contain the cytoplasmic processes of odontoblasts
  17. 37. more in predentin, prevent premature mineralization until the collagen
Down
  1. 2. the type of tertiary dentin that is deposited by newly differentiated odontoblast-like cells
  2. 4. Deficiencies in mineralization during periods of illness, changes of body metabolism, or inadequate nutrition.
  3. 5. bind to large amounts of calcium, bind to collagen and able to initiate crystals formation.
  4. 6. DSPP mutations result in dentinogenesis imperfecta
  5. 8. Provides Rigidity, type I acts as a scaffold that accommodates minerals in the pores & holes of fibrils.
  6. 10. Black granules- like, only clear in ground section, Increase apically.
  7. 11. The layer which is deposited subjacent to the mantle dentin. It forms the bulk of the tooth. It contains collagen fibers of finer diameter than those of the mantle dentin.
  8. 12. incremental lines in the peritubular dentin of the tooth that correspond to the daily rate of dentin formation.
  9. 13. attain the correct dimension
  10. 15. A highly mineralized layer of dentin about 1 micrometer thick surrounding each tubule
  11. 17. extension of odontoblasts process occasionally crossing the junction and passing into the enamel
  12. 18. the type of dentin that is deposited at specific sites in response to injury
  13. 19. Type of Dentin that formation begins after complete root formation
  14. 21. type of dentin that is formed between the dentinal tubules
  15. 23. fracturing of the enamel,wearing of occlusal surfaces, and staining of exposed dentin.
  16. 26. Type of tertiary dentin that is deposited by preexisting odontoblasts
  17. 29. Detected in peritubular dentin, inhibit its growth and thus prevent D.T. occlusion.
  18. 31. 15-20 micrometers wide and lacks the protein phosphophoryn. It contains large diameter collagen fibers that are oriented perpendicular to the DEJ, lying between the processes of the odontoblasts
  19. 33. Catalyse reactions
  20. 35. a relatively rapid pace
