Relative Dentifrice Abrasivity On Dentin And Enamel, Laura Marchetti
Relative Dentifrice Abrasivity On Dentin And Enamel, Laura Marchetti
Theses
The abrasive characteristics of six (6) brands of toothpastes on Enamel and Dentin material were assessed. Human teeth were sliced to expose the dentin surface and then polished using 3 μm and 0.25 μm diamond paste. The outside surface of the tooth (after slicing) was used "as is" for the enamel surface testing. The surface smoothness was evaluated prior to testing using a surface profiler and averaging four (4) to five (5) readings across the surface for each sample.
The tooth slices were then embedded into the acrylic plate surface by routing out an area with a dental drill and …
