1.

Defluoridation of water can be done by:
- A.
  
  Line and alum
- B.
  
  Bleaching powders
- C.
  
  Potassium permanganate
- D.
  
  Sodium chloride
Correct Answer
A. Line and alum

Explanation
Line and alum can be used for defluoridation of water. Alum, also known as aluminum sulfate, is a commonly used coagulant in water treatment processes. It helps in removing impurities and suspended particles from water. Lime, also known as calcium hydroxide, is used to raise the pH of water and to precipitate fluoride ions. When lime and alum are used together, alum acts as a coagulant and lime helps in the precipitation of fluoride ions, resulting in the removal of fluoride from water. Therefore, line and alum can effectively remove fluoride from water during the defluoridation process.

Chose the most effective mechanical device for cleaning interdental surface of teeth:
- A.
  
  Interdental brushes
- B.
  
  Conventional toothbrush
- C.
  
  Powered tooth brush
- D.
  
  Triangular tooth picks
Correct Answer
A. Interdental brushes

Explanation
Interdental brushes are the most effective mechanical device for cleaning interdental surfaces of teeth. These brushes are specifically designed to reach the spaces between teeth and remove plaque and food debris. Unlike conventional toothbrushes, interdental brushes have small bristles that can easily fit into these narrow spaces, ensuring thorough cleaning. Powered toothbrushes may also be effective, but interdental brushes provide more precise cleaning in hard-to-reach areas. Triangular toothpicks are not as effective as interdental brushes because they may not be able to clean the interdental surfaces as thoroughly.

Gingivitis is initiated most commonly by:
- A.
  
  Local irritation factors
- B.
  
  Calcium deficiency
- C.
  
  Malocclusion
- D.
  
  Vitamin deficiency
Correct Answer
A. Local irritation factors

Explanation
Gingivitis is most commonly initiated by local irritation factors. This includes factors such as poor oral hygiene, plaque buildup, and irritants like tobacco or certain medications. These factors can cause inflammation of the gums, leading to gingivitis. Calcium deficiency, malocclusion, and vitamin deficiency can contribute to oral health issues, but they are not the primary cause of gingivitis.

Correct Answer
A. Pit fissure sealant

Explanation
Pit fissure sealant is a primary prevention service that is typically provided in the community, rather than by dental professionals. This is because pit fissure sealants are applied to the chewing surfaces of teeth to prevent the formation of dental caries. The application of sealants is a simple procedure that can be performed by trained individuals, such as dental hygienists or community health workers, in non-dental settings like schools or community centers. This allows for increased access to preventive care for individuals who may not have regular access to dental professionals.

In the context of oral health, a supervised brushing program is an effective primary prevention measure. This program involves providing guidance and supervision to individuals, particularly children, in order to ensure proper brushing techniques and habits. By promoting good oral hygiene practices, such as regular and thorough brushing, the risk of dental diseases, such as cavities and gum disease, can be significantly reduced. Therefore, a supervised brushing program is a suitable example of primary prevention in oral health.

- A.
  
  1 ppm
- B.
  
  1.5 ppm
- C.
  
  2 ppm
- D.

The most cost – effective method for prevention of dental caries is:
- A.
  
  Water fluoridation
- B.
  
  Fluoride fissure – sealants
- C.
  
  Fluoride mouth washer
- D.
  
  Fluoride in salt
Correct Answer
A. Water fluoridation

Explanation
Water fluoridation is the most cost-effective method for preventing dental caries. Fluoride is added to the public water supply, which helps to strengthen tooth enamel and prevent tooth decay. This method is effective because it reaches a large population and requires minimal effort from individuals. Fluoride fissure-sealants are also effective, but they are more expensive and require professional application. Fluoride mouthwash and fluoride in salt are not as cost-effective as water fluoridation because they require individuals to purchase and use these products regularly.

  Sex

In analysis, data and information are carefully examined and interpreted to gain insights and understanding. Similarly, in diagnosis, medical professionals assess symptoms, perform tests, and make a determination about a patient's condition.

The correct answer is "Examination" because a survey is a systematic method of gathering data or information from a group of individuals to gain insights or understand their opinions, preferences, or experiences. Similarly, an examination is a systematic method of assessing someone's knowledge, skills, or abilities through a series of questions or tasks. Both involve gathering information or assessing individuals in a systematic manner, making them essentially the same in this context. The other options, such as diagnosis, treatment, and evaluation, do not accurately represent the concept of a survey.
