Abstract: The presence of diverse microorganisms in the gingiva of patients having periodontal disease is very well known to be deleterious to gingival health, and particularly to facilitate the appearance and development of dental cavities. Such microorganisms are always associated with periodontal disease, and if such microorganisms remain unchecked or uncontrolled, extraction of teeth are likely to occur. In the past, the presence of microorganisms in the gingiva of patients with periodontal disease has been periodically and erratically treated with anti-microbial agents, including antibiotics. For anti-microbial agents and antibiotics to be effective in the gingiva, such agents and antibiotics must come into direct contact with microorganisms, and such contact is known to be incomplete, partly because there may be barriers of fluid and tissue which prevent direct contact between the agents and antibiotics with the microorganisms.

Abstract: A wiring distribution system including connectors, tools, and methods is provided for building wiring. The mechanical and electrical interconnection is performed to the individual connector components in a crimping operation to the individual wires after removal of the outer covering. Using panels with apertures for accepting interchangeable connectors reduces the layers of connecting panels used between a wallplate and a computer.

Abstract: An improved voltage non-linear sintered resistor which includes zinc oxide, bismuth oxide and at least one metal oxide additive selected from the group consisting of antimony oxide, silicon oxide, and mixtures thereof. The sintered resistor includes at least two crystalline phases including .alpha. and .delta. crystalline phases of bismuth oxide and has a quantity ratio of .alpha./.delta. crystalline phases of bismuth oxide of about 0.1-0.8.
