1. The odor of necrosis will usually be
detected even before the pulp chamber is opened because dentin
becomes saturated with by-products of protein denaturation.
2. If
caries is not managed preventively, the restorative treatment will be doomed
to a cycle of disease, repair, new disease and further repair, and
before too long, extraction.
3. Undermined enamel is brittle and in due course (will be fractured if subjected to occlusal forces, producing a large cavity.
4. The state of the tissue at any time will depend on the balance between the attacking forces and the defence reactions.
5.
In many cases removing the adjacent tooth will improve access for
cleaning, and even relatively large enamel lesions will be partially remineralized.
