Presentation Transcript

  1. 1.) Name the two dental arches.

  2. Maxillary (Mx)Mandibular (Mn)

  3. 2.) Name the two sets of teeth for the human.

  4. Primary / DeciduousPermanent

  5. 3.) When does the Transitional or Mixed Dentition Period begin and end?

  6. The Transitional Dentition Period lasts from 6 to 12 years of age The Transitional or Mixed Dentition Period is defined by the presence of both Primary and Permanent teeth in the oral cavity

  7. 4.) Describe when the Deciduous Dentition Period would end.

  8. The Deciduous Dentition Period ends when the initial permanent tooth erupts into the oral cavity When the initial Permanent Mandibular First Molar erupts at approx. 6 years of age

  9. 5.) In the dental formula, the letters I, C, P, & M represent which teeth?

  10. I = IncisorC = CanineP = PremolarM = Molar

  11. 6.) What is the dental formula for the deciduous dentition?

  12. I 2/2, C 1/1, M 2/2 x 2 = 20 The dental formula for the Primary / Deciduous Dentition

  13. 7.) What is the dental formula for the permanent dentition?

  14. I 2/2, C 1/1, P 2/2, M 3/3 x 2 = 32 The dental formula for the permanent dentition

  15. 8.) Please annotate the Dentition to the right using all 3 systems presented in class.

  16. 9.) Please annotate the Dentition to the right using the International and Universal systems.

  17. 10.) What tooth tissue covers the crown of the tooth?

  18. Enamel is the tooth tissue that covers the crown of the tooth

  19. 11.) What tooth tissue covers the root of the tooth?

  20. Cementum is the tooth tissue that covers the root of the tooth

  21. 12.) What two terms can be used to describe the junction of these two tooth tissues?

  22. Cemento-enamel Junction Cervical Line The Cemento-enamel Junction can be abbreviated CEJ

  23. 13.) Name the other two tissues.

  24. DentinPulp The four tissues of the tooth: Enamel Cementum Dentin Pulp

  25. 14.) Name the portion of the Maxilla or Mandible which supports the teeth within the jaw and surrounds the root of the tooth.

  26. The Alveolar Process The Alveolus is the CAVITY or SOCKET in the alveolar process of the Mx and Mn in which the root or roots of the teeth are fixed

  27. 15.) Name the surface of the central incisor facing the lip.

  28. Labial (La) surfaces which face the lip on anterior teeth are called Labial surfaces, and can also be referred to generically as Facial surfaces

  29. 16.) Name the surfaces of the molars facing the cheek.

  30. Buccal (B) surfaces which face the cheek on posterior teeth are called Buccal surfaces, and can also be referred to generically as Facial surfaces

  31. 17.) Name the surface of any tooth which faces toward adjoining teeth in the same dental arch.

  32. Proximal surfaces of the teeth which face adjoining teeth in the same dental arch are generically called Proximal surfaces

  33. 18.) Name the surface of the tooth facing toward the midline while following the curve of the dental arch.

  34. Mesial (M) the surfaces of teeth which face the midline while following the curve of the dental arch are called Mesial surfaces

  35. 19.) Name the surface of the tooth facing away from the midline while following the curve of the dental arch.

  36. Distal (D) the surfaces of teeth which face away from the midline while following the curve of the dental arch are called Distal surfaces

  37. 20.) Name the surface of any tooth that faces toward the tongue.

  38. Lingual (Li) all teeth have a Lingual surface, it is the surface facing toward the tongue

  39. 21.) Name the teeth considered to be Anterior Teeth.

  40. Central IncisorsLateral IncisorsCanines these three types of teeth in both the Mx and Mn are considered to be Anterior Teeth

  41. 22.) Name the teeth considered to be posterior teeth.

  42. 1st Premolars2nd Premolars1st Molars2nd Molars3rd Molars these five types of teeth in both the Mx and Mn are considered to be Posterior Teeth

  43. 23.) What is the general term used to describe quantitative defects in enamel?

  44. Enamel Hypoplasia the general term referring to all quantitative defects of enamel

  45. 24.) What is the general term used to describe qualitative defects in enamel?

  46. Hypocalcification the general term referring to all qualitative defects of enamel also referred to as Opacities

  47. 25.) What number of weeks in utero does calcification normally begin?

  48. 14 weeks in utero at approximately 14 weeks in utero calcification has initiated for the Mx and Mn Central Incisors of the Primary Dentition
