A dental hygiene system provided with interchangeable dental heads permits power-enhanced brushing and concurrent fluid irrigation to optimize a user's personal dental hygiene efforts. The system has a handle assembly with an irrigation nozzle in close proximity to displaceable bristles driven by a battery-operated handle motor. Pumping of irrigation fluid such as an antiseptic solution into the oral cavity is also motor driven. A telescoping chamber with irrigation fluid fits on the piston-like base end of the handle and is refilled by docking the handle assembly on a complementary docking station that includes a detachable fluid reservoir, microswitch controls and a base fluid pump. Docking of the handle assembly triggers the microswitches and opens a check valve in the bottom of the handle chamber, which activates the flow of fluid from the reservoir into the chamber. An optional fiberoptic subassembly illuminates the oral cavity.

The toothbrush of the present invention comprises an elongated handle having a head attached to one end. The head has a bristle-bearing face having longitudinal perimeter portions adjacent longitudinal edges and at least two perimetric, elastomeric massaging elements alternately arranged with groups of bristle tufts along each of the longitudinal perimeter portions. The brush can comprise further massaging elements which are not located along the longitudinal perimeter portions though the use of such additional elements is preferably minimised. The perimetric massaging elements have rotational symmetry through an angle of 120° or less, preferably being circular. The cross-sectional area proportion of elastomeric massaging elements to bristles on the brush head is less than 25%. Alternately there are four or fewer elastomeric massaging elements which are not perimetric massaging elements. A brush with both bristles and gum massaging elements arranged as set out above provides both cleaning and gum massaging benefits without creating an undesirable aesthetic impression derived from the use of rubber-like materials in the part of the brush head traditionally comprising only bristles.

A device isolation film and an active region are formed on a semiconductor substrate, using a first mask pattern to expose only a formation region of the device isolation film. Only the device isolation film is selectively etched by using the first mask pattern and a second mask pattern as an etch mask, to form a fin only on a gate formation region, the second mask pattern to expose only a gate electrode formation region. A gate insulation layer is formed on both sidewalls of the fin and a gate electrode covering the first mask pattern and the gate insulation layer is formed. Source and drain regions are formed on the remaining portion of the active region where the gate electrode was not formed. Gate electrode separation becomes adequate and manufacturing costs can be reduced.

A cleaning and disinfecting system for the cleaning and disinfecting of footwear or feet. The system provides for cleaning and disinfecting the bottom of the feet or footwear. An optional brush on a wand provides cleaning to upper foot areas as required. The system is automatically activated only when a person stands on the device, thereby minimizing the volume of fluid required to perform the process. Optionally, a venturi component allows the addition of a cleaning or disinfecting fluid with the cleaning solution or water. When the system is attached to a hot water line and fitted with heating elements, it can be used to remove snow from shoes and boots.

This invention relates to a toothbrush that utilizes a replaceable brush head having rubber gum guard on its top surface and a triangular shaped rubber pad on its bottom surface. The rubber gum guard is shorter than the height of the bristles and is positioned on the peripheral edge of a brush head for functioning as a sensor for providing feedback to prevent brushing at excessive pressures and improper angles as well as for massaging the gumlines without the risk of gum damages. The triangular shaped rubber pad is for conforming to and massaging gumlines at the back of teeth. The replaceable brush head having the rubber gum guard and massaging pad features is economically used in conjunction with a permanent handle that dispenses dentifrice material to the top of bristles. The handle has a resilient contractible connector for secure mounting of the replaceable brush head.
