Inspiral brush tip

Example 4

A comparative sample dental adhesive composition devoid of diamond particles was prepared by mixing together the components listed in Table IV:

The dental adhesive composition was then rubbed and/or scrubbed over the surface of a tooth structure covered in dental smear using a dental brush tip, such as the Inspiral® brush tip (commercially available from Ultradent Products, Inc.), for two intervals of 10 seconds each. After scrubbing the tooth surface, the tooth structure was washed with water to remove the dental adhesive composition from the tooth surface. An image of the tooth surface was taken using scanning electron microscopy and is shown in FIG. 4 (magnification 1000×).

As shown in FIG. 4, little to no smear material was removed by the dental adhesive. The dentin tubules are barely visible, indicating that the dental adhesive removed little to no smear material from the dentin tubules. As compared to FIGS. 1, 2 and 3, significantly less of the smear layer was removed from the dentin tubules and/or the surface of the tooth structure.

Example 2

A sample dental adhesive composition was prepared by mixing together the components listed in Table II:

The dental adhesive composition was then rubbed and/or scrubbed over the surface of a tooth structure covered in dental smear using a dental brush tip, such as the Inspiral® brush tip (commercially available from Ultradent Products, Inc.), for two intervals of 10 seconds each. After scrubbing the tooth surface, the tooth structure was washed with water to remove the dental adhesive composition from the tooth surface. An image of the tooth surface was taken using scanning electron microscopy and is shown in FIG. 2 (magnification 1000×).

As shown in FIG. 2, the dental adhesive successfully removed a portion of the smear layer. The dentin tubules are also visible, indicating that the dental adhesive also successfully removed at least a portion of the smear layer from the dentin tubules. As compared to FIG. 1, less of the smear layer was removed from the dentin tubules and/or the surface of the tooth structure.

Example 1

A sample dental adhesive composition was prepared by mixing together the components listed in Table I:

The dental adhesive composition was then rubbed and/or scrubbed over the surface of a tooth structure covered in dental smear using a dental brush tip, such as the Inspiral® brush tip (commercially available from Ultradent Products, Inc.), for two intervals of 10 seconds each. After scrubbing the tooth surface, the tooth structure was washed with water to remove the dental adhesive composition from the tooth surface. An image of the tooth surface was taken using scanning electron microscopy and is shown in FIG. 1 (magnification 1000×).

As shown in FIG. 1, the dental adhesive successfully removed a portion of the smear layer. The dentin tubules are also visible, indicating that the dental adhesive also successfully removed at least a portion of the smear layer from the dentin tubules.
