Editor's Notes
- What is covered by cariology? (Cariology includes the causes of caries, the process by which caries occurs, and the science and practice of caries management and prevention.) Since the late nineteenth century, dentists have been fighting tooth decay by drilling out the decayed tooth structure and filling the tooth with a restorative material.
- At what stage of caries development should the teeth be protected from demineralization? (Incipient) At what stage does the patient usually first notice the lesion? (Overt or frank) At what stage is it most difficult for the dentist to restore good health to the mouth? (Rampant)
- Accurately diagnosing early dental caries is a challenge for the dentist. What are the pros and cons to each method of caries detection? (Dental explorers have limitations on the occlusal surface. Radiographs may not be able to see early caries; the extent of caries damage may not be fully seen using radiographs. Visual appearance isn't very reliable because teeth stains can be caused by a number of factors. The indicator dyes change the color of teeth where decay has occurred. Some devices detect bacterial by-products and quantify sound signals to aid in caries detection; some detect differences in tooth structure and display the information on a screen. Even the latest approach, the laser caries detector, has limitations. At the current level of technology, it cannot detect caries interproximally or under sealants or restorations, but it is useful in nonrestored areas and around the margins of restorations.)
- The laser caries detector does not detect interproximal caries, subgingival caries, or secondary caries under crowns, inlays, or restorations. An example of this is the DIAGNOdent. When the laser beam passes through a change in the density of the tooth, it gives off a fluorescent light of different wavelengths. A clean, healthy tooth exhibits little or no fluorescence, resulting in very low readings.
- Ask how many students have had composites placed in their mouths and if they are able to tell which teeth are composites by visual examination or touch. (Answers will vary.)
- Direct composite resin restorations are typically more costly than their amalgam equivalent. Placement is very technique sensitive and requires more time, due to incremental addition and curing of the material. These materials are usually light-cured and are as hard as they will ever be when the patient leaves the office. This is different than the silver amalgam restorations, which can be carved for a while following placement, and continue to harden after the patient leaves the office.
- Amalgam set up pge 806 3dr edition steps are sign off on lab:
- A, Before. B, After. A skilled operator is able to disguise a composite restoration using color or color combination and by incorporating contours similar to the tooth’s contralateral.
