  1. 1. Dentin, Pulp, Canals, wear facettes occl. (Enamel)

  2. 2. Periodontal Membrane space - left.Laminadura - right

  3. 3. Pulp - leftAmalgam restoration - middle – (3 roots)Amalgam restoration - right

  4. 4.Shadow of the nose(Nasal fossae & incisive foramen)Shadow of the lip

  5. 5.Interdental nutrient canals in the anterior region of the mandible.

  6. 6.Top: external oblique ridgeBottom: Mylohyoid ridge / line or internal oblique ridge.

  7. 7.Mental Foramen

  8. 8.Mandibular canal & (external oblique ridge) (lower border of the mandible)(radiopaque cortical bone)

  9. 9.Lingual ForamenSeen as a small round radiolucent area in the midline & below the roots of the mandibular central incisors Genial tuberacles (the muscle attachment for the geniohoid muscle)

  10. 10. Coronoid process of the mandible-the tapered radiopaque structure below the max. tuberosity.

  11. 11.Zygomatic Process (U shaped) radiopacity

  12. 12.Maxillary tuberosity Hamular process- image is seen posterior to the tuberosity of the maxilla.

  13. 13. Maxillary Sinus

  14. 14.Septum of the maxillary sinus

  15. 15.Hamular process

  16. 16.Floor of the nasal fossa (palate irregular radiopaque line)

  17. 17. a. Nasal Fossae - leftb. Nasal Septum - right

  18. 18.Thin dark line is palatine suture

  19. 19.Left - Incisive or anterior palatine foramen (nasal septa) Right - nasal spine

  20. 20. Calculus

  21. 21.Left: Contact Point with Right: incipient decay

  22. 22.Advanced Decay - Radiolucent

  23. 23.Recurrent Decay under restoration

  24. 24.Occlusal Decay

  25. 25. Decidous Decay – Radiolucent (primary tooth root resorption)

  26. 26.Overhang amalgam (crestal bone loss, moth eaten appearance)

  27. 27. Periopical Abscess (pulp stone?)

  28. 28.3rd molar impactednot fully formed

  29. 29.Impacted tooth – cuspid

  30. 30.Retained Root tip

  31. 31.Level of bone V.S. level of the gingiva, vertical bone loss leading to the visible perio pocket. C.E.J. line---

  32. 32.Space between tooth and amalgam food/plaque trap, crestal bone loss

  33. 33.Root resorption (calculus) (bruaxtor)

  34. 34.Bifurcation involvement almost “thru & thru”

  35. 35.Internal resorption – less radiolucent than decay (maxillary sinus & zygomatic process U, zygomatic arch – wavy)

  36. 36.Tori (increased radiopacity)

  37. 37.Pulp chamber with pulpstones – dystrophic calcification

  38. 38. Hypercementosis- result of inflammation, stress or lack of an antagonist.

  39. 39.Dilacerated root- obstruction during eruption

  40. 40.Paramolar

  41. 41.Mesiodens

  42. 42.Fracture in tooth leaves an irregular positive (dark) image below wire splinted teeth.

  43. 43.Bone fragments and fracture result of an accident

  44. 44.Crowns - radiopaque one with pins (metal or porcelain over metal)

  45. 45.Stainless steel crown - less radiopaque than gold

  46. 46. Space maintainer & distal decay

  47. 47.Anterior restoration (acrylic or silicate as radiolucent as decay)

  48. 48.Crown - P.J.C. Cement line porcelain density similar to dentin. White processing artifact.

  49. 49.Pins in anterior build-up (acrylic restorations)

  50. 50.Silver endo point- right: composite restoration (as radioplaque as enamel)
