Radiodense</li></ul>38- Plaque and bacteria with simple sugar produce acid and is in the <br /> a. demenerlization stage<br /> b. reminarlization stage<br /> c. acidic stage<br />True or fales:<br /><ul><li>Dental caries is a chronic infectious disease that involves the demineralization of the mineralized tissues of teeth by acids produced by metabolism of dietary carbohydrates by plaque micro-organisms, but is influenced by fluoride and other factors. ( )
  44. 44. If the enamel is worn off (damaged) by the dental caries the next part to get affected is the cementum. ( )
  45. 45. The tooth is sensitive and we can’t bite down on tooth when the caries are on the enamel. ( )
  46. 46. Epidemiology is the study of health and disease states in individuals rather than populations. ( )
  47. 47. People who are financially poor and those who live in rural areas are more prone to caries than other people. ( )
  48. 48. When naming caries we start with the severity then the anatomical site and then the status of the lesion. ( )
  49. 49. primary lesion begins on a surface with no previous lesion or restoration.
  50. 50. Moderate caries are the least in severity.
  51. 51. GV black classification of caries lesions,Class 3 is Proximal surfaces on anterior teeth.
  52. 52. The mount and hume classification for dental caries involves the size and the severity.
  53. 53. Dental caries are reversible.
  54. 54. Acidic foods/drinks do cause caries on their own .
  55. 55. Xerostomia means dry mouth and it can cause caries.
  56. 56. When the pH is more than 6.5 the stage is favouring to demeneralization.
  57. 57. Saliva Saturated in calcium and phosphate ions causes caries.
  58. 58. The tooth is continuously bathed with fluoride in the enamel and dentin..</li></ul>The end <br />Done by: Hessa Habib <br />
