Abstract: A dental tool tip is removably attached to a vibratory dental handpiece. The dental tool tip includes a mounting base configured for removable engagement with the dental handpiece, the mounting base having an open-ended, internal bore extending therethrough and configured for fluid communication with the dental handpiece and a body having a free distal, terminal end and at least a portion of the body having an abrasive coating. A mounting rod proximally extends from the body and is at least partially received within the internal bore. The mounting rod has at least one open-ended passage extending therethrough and in registry and fluid communication with the internal bore, thereby being configured to enable at least one of air or water to advance from the dental handpiece, and flow out onto the body, via the internal bore and the at least one channel.

Abstract: A method for dynamically personalizing transportation in a vehicle comprises the steps of providing a vehicle including a messaging device for displaying messages, providing a central dispatch system for managing passenger allocation to the vehicle, receiving passenger specific information at the dispatch system, providing data relating to the passenger specific information from the dispatch system to the messaging device, and selecting and displaying a message based on the data for display. Further, a method is disclosed in which messages depending on passenger specific information, and messages independent form passenger specific information are selected and displayed. The messaging device is in communication with a video display unit or with a printing device for displaying messages received.
