Which of the following is NOT typically included in a personal health history?

The choice of social security number as something that is not typically included in a personal health history is valid because personal health histories generally focus on information directly relevant to health and medical care, such as demographics, medical history, medications, allergies, and healthcare providers. While an individual's social security number can be used for various administrative purposes within healthcare systems, it is not essential for understanding a person’s health status or history.

The included items in a personal health history, such as address, physician's name, and date of birth, provide necessary context for identifying the patient, understanding their medical care, and ensuring proper treatment communication. The address helps with location-related health factors, the physician's name indicates healthcare continuity, and the date of birth is fundamental for demographics and age-related health considerations. Therefore, while essential for broader administrative and identification purposes, the social security number is usually excluded from the personal health history that directly impacts dental hygiene and health assessments.
