A method and apparatus for bleaching teeth. The method involves heating a dental bleaching solution capable of yielding a bleaching vapor having a concentrated peroxide molecule content when heated until the bleaching vapor is obtained, and thereafter applying the bleaching vapor to a surface of at least one tooth in order to bleach the tooth. The apparatus includes a housing defining a chamber to be partially filled with a bleaching solution, the bleaching solution being capable of yielding a bleaching vapor having a concentrated peroxide content when heated. The apparatus further includes a heating device for heating the bleaching solution partially filling the chamber for generating the bleaching vapor within the chamber in pressurized form; a delivery device connected to the housing for delivering the pressurized bleaching vapor from the chamber to a surface of at least one tooth to be bleached; and a control device operatively associated with the chamber and the delivery device for regulating a delivery of the bleaching vapor to the surface of the tooth.

A device and method for relieving head, neck, facial, joint and tooth pain. An intra-oral device, worn over the upper or lower incisors, allows at least one opposite tooth to contact the rear wall of the device, only within the user's freeway space, and prevents upper and lower posterior teeth from contacting. The device facilitates deprogramming and releasing of the upper and lower jaw muscles. The device includes an extruded or molded shell made of a hard polycarbonate or similar hard plastic material. The internal surface of the shell may be secured in place for the user or lined with a low molding temperature thermoplastic resin, allowing the user to mold the internal aspect of the device onto and over the teeth to produce a fitted device. This relieves the stresses, strains, pains and damage that can be caused by parafunctioning of the dental neural-muscular system.

A system and method are provided in which a laminar flow of pressurized gas from a curved slit in a chamber is directed across a surface to propel a laminar flow of a liquid, below the laminar flow gas, across the surface to prevent surface contamination or remove contaminants from the surface. In a particular application, the system and method are employed in a self-cleaning dental mirror tool including a dental mirror attached to a handle, wherein the gas is air, the liquid is water, and the surface is the reflective surface of the dental mirror.

A time keeping device, including an integrated circuit memory containing tide table data, having the ability to provide custom port information using user supplied offsets. The device provides a tide prediction system to predict and display the times of high and low tides for numerous ports and adjacent areas spanning, for example, the East, West, and Gulf Coast regions of the continental U. S. The device allows the setting and display of the different Port/Substations supported by the tide prediction system, displays the current time, date, and day of the week in standard or military format (24 hour clock), and adjusts for Daylight Saving time. Displays are provided for the phases of the moon from New to Full and back to New Moon, indicating whether it is waxing or waning, and for the current water level height An audible alarm may be generated for the arrival of a new hour, arrival of the next tidal event, or the arrival of a time preset by the user, and the device may also function as a stop watch. The user of the device may establish a plurality of Custom Ports by setting time offsets for high and low tidal events relative to any tidal port supported by the system.

A device and method for relieving head, neck, facial, joint and tooth pain. An intra-oral, semi-custom, separating device, worn over the upper anterior teeth, allows at least one lower anterior tooth to contact the rear wall of the device within the user's freeway space and prevents lower posterior teeth from contacting upper posterior teeth. The device provides a method of deprogramming and releasing the muscles of the upper and lower jaws. The device comprises an extruded or molded shell made of a hard polycarbonate or similar hard plastic material. The internal surface of the shell is lined with a moldable thermoplastic resin with a low molding temperature which allows the user to mold the internal aspect of the device onto and over the teeth to produce a custom fitted device. This relieves the stresses, strains, pains and damage that can be caused by parafunctioning of the dental neural-muscular system.
