Publication number: 20030053963Abstract: A dental fluoride rinse system comprising two different dental rinse compositions, typically maintained in separate vessels until the time that they are mixed with an appropriate solvent such as water. The first dental composition provides a non-stannous fluoride ion source and a phosphate ion source that has a pH of about 3.75+ or −0.75 when mixed with water and comprises greater than about 1% by weight of the fluoride ion. The second dry composition provides between about 0.1% and 1% stannous fluoride when mixed with the solvent and is administered to the patient after the first rinse composition so that the patient gets two different kinds of fluoride administered to the oral cavity in a short time period. In a significant advantage of the present system, the stannous fluoride can be mixed with water by the user.Type: ApplicationFiled: May 10, 2002Publication date: March 20, 2003Applicant: Pascal Company, Inc.Inventors: Joseph J.

Patent number: 4978510Abstract: A sterilizing tray for holding objects while they are being sterilized in a sterilizing solution. At least one end of the sterilizing tray is equipped with a top pivoting end door whose latch can be released by tipping the end of the sterilizing tray against the work surface. Once the latch is released, the weight of sterilized objects in the tipped sterilizing tray pushes the end door open, thereby depositing the sterilized objects neatly on the work surface without their ever having been touched by the user.Type: GrantFiled: July 18, 1988Date of Patent: December 18, 1990Assignee: Pascal Company, Inc.Inventor: Lawrence C.

Patent number: 4902227Abstract: A molded, one-piece plastic dental treatment tray for applying fluoride or other medication to a patient's teeth. The tray has a pair of elongated locking flanges on one of its handles which engage the lateral edges of the other of its handles to hold the tray folded up with its two teeth receiving troughs in an aligned, assembled relationship. At least one of the handles is molded at an angle with respect to the bottom of its trough to help ensure that when the tray is folded up, the free ends of its troughs are urged into contact with each other, to enable the tray to be inserted more easily into the patient's mouth. The bottoms of the troughs are flat and smooth enough for them to move easily over each other in any direction while in the patient's mouth, so the tray will better accommodate any individual differences in the mouth, jaws or teeth of the particular patient.Type: GrantFiled: May 4, 1988Date of Patent: February 20, 1990Assignee: Pascal Company, Inc.Inventor: Lawrence C.

Patent number: 4232688Abstract: A gingival cord container cap is disclosed featuring a cord dispensing gate mechanism formed by cooperating parts of a pivoted dispensing spout and a cap base in which the spout is socketed. Cord threaded out of the container through a hole in the cap base and through the spout may be withdrawn freely when the spout is swung into alignment with the hole in the base (i.e., the gate-open position). As the spout is pivoted out of such alignment (closing the gate) the cord is pinched and held, so that it may be cut off flush with the aperture of the spout, protectively retaining the remainder in the container. Swinging the spout back into aligned position causes a short segment of the pinched cord to be automatically projected out of the tip of the spout where it can be manually grasped for withdrawing additional cord from the container as needed.Type: GrantFiled: September 26, 1978Date of Patent: November 11, 1980Assignee: Pascal Company, Inc.Inventor: Reed H.
