Developmental defects are those described under ‘intrinsic' staining, but post-eruptively these defects can acquire further stain. Conditions that cause any form of enamel hypoplasia are especially prone and exposed dentine is especially vulnerable to the uptake of dietary chromogens. Acquired defects...
Poor alignment of the bite can cause the enamel on certain teeth to wear down rapidly, leaving soft dentin exposed. Orthodontics is a great cavity-prevention measure because straight teeth that are in a proper bite position tend to stay cleaner and more cavity-free throughout a person's life...
In addition, research shows that if teeth are exposed to tetracycline at the time of tooth calcification and mineralization, tetracycline will bind calcium ions in the teeth. If this occurs before tooth eruption, the bound tetracycline will cause the teeth to erupt with an initial fluorescent yello...
(Fig. 19-19). If the permanent tooth is exposed in theoral cavityand at a lower occlusal plane than the adjacent teeth, ankylosis is the probable cause. Both Biederman and Skolnick havedescribed a luxation technique effective in breaking the bony ankylosis.43,44If the rocking technique is ...
Based on comparisons with the skull of the holotype of Stegosaurus stenops USNM 4934 (Kimmeridgian–Tithonian, Morrison Formation, Wyoming, USA), with mostly maxillary teeth exposed, the teeth of which were described by Gilmore (1914) and recently by Galton (2007), we can attempt to ...
When the dentin is exposed, these tubes can be stimulated by changes in temperature or certain foods. Here is an image of what the dentin tubes look like under the microscope: What causes it? Exposure of the dentin can occur due to a number of factors. Some of the more common reasons ...

Some of the most challenging patients to produce a pleasing smile for are those who present with inadequate tooth display (either due to tooth position, the patient has normal size teeth, but they aren't exposed adequately to fill out the smile) or due t

Dental enamel is the outermost layer of the human tooth, covers the crown surface, and is exposed directly to the oral cavity. It varies in thickness up to 2.5 mm.3 Dental enamel is the most extreme case of mammalian biomineralization and is the hardest substance in the body. The color of...
