Tooth wear indices grade the severity of wear by recording the surface characteristics of teeth with a numerical score.
Although a meticulous approach was employed in the current review to retrieve the relevant papers that would answer the focused review question, there are still some limitations due to the variability between the included trials in fixed appliance characteristics, biomechanics of tooth movement, and the methods of outcome measurements.
What's more, an extended method to get tooth surfaces from a space curve and its conjugate curve is proposed and the meshing characteristics of these tooth surfaces are argued.
The geometric characteristics of the tooth profiles of bevel gears can be studied by using the kinematics parametric polar angular (pressure angle) function, the meshing equation and the constraints of continuity conditions.
In fact, the multitudes of physical and chemical assaults occurring during a lifetime result in a more or less characteristic pattern of tooth wear.
Based on the characteristic features of tooth development, to generate an implantable tooth germ in vitro, one of the cell sources, either epithelial or mesenchymal population, must acquire odontogenic potential to initiate regenerative process.
If teeth are present, you can still estimate the age based on the number and characteristics of the teeth.
Correlation between symptoms and external characteristics of cracked teeth.
The plastic records characteristics of individual teeth, and it also scoops up a healthy dose of spittle.
The most frequently mentioned contraindications for fixed retainers were caries, a periodontal disease, poor oral hygiene, deep bite, incomplete treatment result, and the anatomical characteristics of the teeth (Fig. 2).
