    Explanation
    Screening refers to the process of testing individuals or populations who are not actively seeking healthcare in order to detect any infections or diseases. It is a proactive approach to identify potential cases early on, even before symptoms are present. This can help in preventing the spread of the infection or disease and initiating appropriate treatment or interventions. Screening is often done through various methods such as laboratory tests, questionnaires, or physical examinations. It is different from diagnosis, which involves determining the specific condition or disease in an individual who is already seeking healthcare. Case-finding and case-looking are not commonly used terms in this context.

    Examining a patient in dental office is equivalent to community dental health:

    • Surveying

    • Analysis of data

    • Program planning

    • Program operation

    • Education

    Correct Answer
    A. Surveying
    Explanation
    Examining a patient in a dental office can be considered equivalent to surveying in community dental health. When a dentist examines a patient, they gather information about the patient's oral health status, identify any issues or concerns, and collect data on various aspects such as dental hygiene, cavities, gum health, and potential oral diseases. Similarly, in community dental health, surveying involves collecting data and information about the oral health status of a population or community. Both processes aim to gather relevant data and information to assess the oral health needs of individuals or communities, and to identify any areas that require intervention or improvement.
