WHY IS DIAGNOSIS IMPORTANT
June 24th, 2009 by admin
|
Diagnosis is important for three reasons: |
|
2 |
|
• It forms the basis for a treatment decision. Active lesions require some |
|
form of active management whereas arrested lesions do not. |
|
• Informing the patient. The patient is central to the management of the |

SECONDARY OR RECURRENT CARIES

what is secondary carry=?
|
Secondary or recurrent caries is |
|
primary caries next to a filling |
|
caused by |
|
the biofilm at the tooth surface or the surface of any cavity. |

ROOT CARIES

Up to now this chapter has considered caries of dentine beneath enamel |

ACTIVE AND ARRESTED LESIONS IN DENTINE
June 24th, 2009 by admin
|
The rate of progress of caries in dentine is highly variable, and under suitable |
|
environmental conditions the carious process can be arrested and the lesion |
|
may even partly regress. Clinically, actively progressing lesions are soft and |

THE MICROBIOLOGY OF DENTINE CARIES
June 24th, 2009 by admin
|
The first wave of bacteria infecting the dentine is primarily acidogenic. Since |
|
demineralization precedes bacterial penetration, the acid presumably dif- |
|
fuses ahead of the organisms. The pH of carious dentine can be low, and |
|
members of the dentine bacterial community in active lesions tend to be |

INFLAMMATION OF THE PULP
June 24th, 2009 by admin
|
In ammation is the fundamental response of all vascular connective tissues |
|
to injury. In ammation of the pulp is called |
|
pulpitis |
|
and, as in any other |
|
tissue, it may be acute or chronic. The duration and intensity of the stimulus |

CAVITATION—AN IMPORTANT MOMENT
June 24th, 2009 by admin
|
The important moment clinically may be the breakdown of the outer ena- |
|
mel, presumably created by mechanical injuries during mastication, micro- |
|
traumas during interdental wear, or careless probing. It is important because |

DENTINE REACTIONS
June 24th, 2009 by admin
|
The dentine has been reacting to the carious process in the biofilm long before |
|
a cavity forms. Dentine is a vital tissue, permeated by the tubules containing |
|
the cell processes of the odontoblasts, and it defends itself by the |

The shape of the lesion and its clinical implication
June 24th, 2009 by admin
|
On a smooth surface the lesion is classically triangular in shape. It follows the |
|
direction of the enamel prisms and can be thought of as multiple individual |
|
lesions each at a different stage of progression. The central traverse, where |

Arrest of lesions
June 24th, 2009 by admin
|
Inactive or arrested white spot lesions have a shiny surface and may be |
|
brown in colour, having picked up exogenous stains from the mouth |
|
(Figures 1.7 and 2.7). These lesions cannot be detected by gently drawing a |
|
sharp probe across them because they feel the same as normal enamel. Histo- |
