tooth.
-Results from forces of friction between the teeth or external objects.
-Can happen from improper brushing technique or the use of a toothpick or pipe.
Attrition - Answer ✔✔-Results from forces between the teeth.
, -Wear on the incised and occlusal surfaces from grinding.
Abfraction - Answer ✔✔-Biomechanical destruction related to fatigue, flexure, and
deformation of tooth structure.
-Can appear as a wedge-shaped lesion at the cervical third of the tooth.
What is the most effective public health measure to prevent tooth decay? - Answer
✔✔Community Water Fluoridation
New recommended level of fluoride is? - Answer ✔✔0.7 ppm
Old level of fluoride is? - Answer ✔✔0.7-1.2 ppm
