(a)
Interpretation:
The community water fluoridation is cited as one 10 greatest public health achievements of the 20th century by the U.S. Centers for disease control and prevention, the behind reason should be explained.
Concept introduction:
Dental Plaque: it is defined as a specific but highly variable structural entity resulting from sequential colorization and growth of microorganisms on the surface of teeth and restoration consisting of microorganisms of various strains and species embedded in the extra cellular matrix composed of bacteria
(b)
Interpretation:
Important in all communities water fluoridation is especially important low-income communities, the behind reason should be explained.
Concept introduction:
The upward adjustment of the concentration of fluride ion in a public health water supply such a way that concentration of fluride ion in water may be consistently maintained at one part per million by weight to prevent dental caries with minimum possibility of causing dental fluorosis.
Fluoridation: Fluride present during tooth formation provide caries resistance systematic incorporation of fluride into enamel during development.
(c)
Interpretation:
Some community’s water fluoridation is highly controversial. The arguments against adding fluride to drinking water the reason should be explained.
Concept introduction:
Fluoridation: Fluride present during tooth formation provide caries resistance systematic incorporation of fluride into enamel during development.
The upward adjustment of the concentration of fluride ion in a public health water supply such a way that concentration of fluride ion in water may be consistently maintained at one part per million by weight to prevent dental caries with minimum possibility of causing dental fluorosis.

- The amount of water present on Earth is constant. In spite of this, water crisis is experienced by people in some communities/countries. Why is there inadequacy of water supply?arrow_forwardYou can get a "water clock", which works by simply adding water to it. How must it work? a. The energy comes from the water itself. b. It must have a solar cell to convert the water into hydrogen for a fuel cell. c. The water creates the electrolytic solution in the clock's voltaic cell. d. The polar nature of water produces small amounts of electricity.arrow_forward1-What are the effects of requisites of drinking water?2-Give your recommendation to improve different conditioning methods used to prevent scale formation?arrow_forward
- (A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. Insufficient dissolved oxygen is necessary for the life of fish and other aquatic organisms. As aquatic photosynthesis is light dependent, the dissolved oxygen produced will peak during daylight hours and decline at night. 2. The solubility of oxygen in water increases at colder temperatures, and decreases at higher temperatures. DO can be measured in milligrams of oxygen (O2) per liter of water. 3. The ideal electrical conductivity of totally pure water is 0.055 microSiemens, whereas typical deionized water has an electrical conductivity of 0.1 microSiemens. The freezing point of water at 1 atm is 100degC. 4. When water is mixed with metals, a metal hydroxide is formed and oxygen gas is evolved. The evolution of the oxygen gas from the reaction of metals and water is indicated by the hastened…arrow_forwardThe Safe Drinking Water Act (ADWA) sets a limit for mercury- a toxin to the central nervous system- at 0.0020 ppm by mass. Water suppliers must periodically test their water to ensure that mercury levels do not exceed this limit. Suppose water becomes contaminated with mercury at twice the legal limit (0.0040 ppm). How much of this water (L) would a person have to consume to ingest 50.0 mg of Hg?
