  19. Personal, Medical, Dental History


    Assessment of Patient Includes:
    - gathering, organizing, and analyzing all data. It is a collection of all pertinent facts and materials to use as a guide during care planning and treatment.

    - a complete patient history is an essential part of the complete assessment.
  20. purposes of the history:
    • A. provides info pertinent to the diagnosis of oral conditions and the total treatment plan.
    • B. reveals conditions which necessitate precautions, modifications or adaptations during appointments to assure dental hygiene procedures will not harm the patient and emergency situations will be prevented.
    • C. aid in identifying unrecognized conditions for reference and for further diagnosis or treatment.
    • D. permits appraisal of general health and nutritional status.
    • E. give insight into emotional and psychological factors which may effect present and continuing care.
    • F. document records for reference and comparison over a series of appointments.
    • G. maintain legal documentation, furnish evidence in legal matters.
  21. The major rationale for taking the patient's health history is to identify:
    • A. diseases or medications that contraindicate dental or dental hygiene care.
    • B. diseases or conditions that require special precautionary measures for the patient prior to care.
    • C. reactions to drugs or patient allergies.
    • D. infectious diseases that endanger others
    • E. Special physiological states such as pregnancy
  22. History preparation
    • A. the general method for obtaining a Health History on a patient is by questionnaire and interview or review with follow up questions.
    • B. the patient should be given the form to complete when they arrive for appointment and they should be given a black ink pen and a seat in the reception area.
    • C. make sure patient understands the importance of answering everything truthfully. after the patient answers all questions, you may take them back to the dental chair, review questions and follow up on all "yes" answers.
    • *certain questions you will need to ask again - hospitalization/date, medication, heart conditions, allergies.
    • D. all three sections of the health history must be reviewed (personal, medical, dental)
  23. Personal History includes:

    C. patient's physician for consultation
  24. Dental History includes:
    A. *address first* Immediate problem or complaint; cause of pain or discomfort

    C. attitude of patient toward oral hygiene habits

    D. personal daily care and dental habits performed by the patient
  25. Medical History includes:

    2. Prophylactic Antibiotic Premedication
    • A. Dental or dental hygiene procedures which may cause bleeding of tissues has the potential for creating a bacteremia (bacteria in the bloodstream)
    • B. Infective microorganisms (especially Alpha Hemolytic Streptococcus) in the blood stream may lodge on damaged or abnormal areas of heart valves, lining of the heart, or the underlying connective tissue.
    • C. When this occurs it causes: Infective Endocarditis, and can be life-threatening.
    • D. Antibiotic Premedication must be given to patients who are susceptible to infective endocarditis before any dental or dental hygiene care is provided.
  29. C. Conditions under treatment by a physician that require medicating drugs that may influence or contraindicate treatment

    1. Anticoagulant therapy
    Blood thinners - Coumadin, heparin, Warfarin

    physician must be consulted to see if reduction of medication is indicated (usually not adjusted)
  30. C. Conditions under treatment by physician that require medicating drugs that may influence or contraindicate treatment.

  31. C. Conditions under treatment by a physician that require medicating drugs that may influence or contraindicate treatment

    3. Diabetes
    (some diabetic patients may require antibiotic premedication due to lower immunity - ussually the uncontrolled diabetic)

    recognize the symptoms of undiagnosed diabetic: dry mouth, excessive thirst, frequent urination.

    make sure patient took medication and has eaten breakfast, lunch...

    diabetics tend to be slow healers; minimize tissue trauma.
  32. C. conditions under treatment by a physician that require medicating drugs that may influence or contraindicate treatment

    *no treatment recommended within 6 months, need to check with patient's physician concerning medications prescribed and need for precautions or premedications.
  35. D. Allergic Reactions
    1. ALL allergies to drugs must be noted in RED in upper right corner of history form.
