Medical Conditions and Work Restrictions

Oral health care facilities shall have written policies to protect patients and OHCWs with latex allergies, to protect OHCWs who are susceptible to opportunistic infections, and to protect patients from OHCWs with transmissible infections.
  1. Background

    OHCPs and patients may become susceptible to latex-related adverse reactions, OHCPs may also develop acute or chronic conditions, which may predispose them to opportunistic infections, or OHCPs may acquire potentially transmissible infections. Such individuals should discuss the problem with their personal physician or other qualified authority to determine if the condition might affect their ability to safely perform their duties.

  2. Execution/ Compliance
    1. Minimize latex allergy-related health problems among OHCPs and patients.
      1. Reduce exposure to latex-containing materials by substituting non-latex products when appropriate and using appropriate work practice controls.
      2. Train and educate OHCPs to recognize signs and symptoms of latex-related adverse effects, i.e.,
        1. Allergic contact dermatitis
        2. Urticaria
        3. Angioedema
        4. Allergic rhinitis
        5. Anaphylaxis
      3. Monitor signs and symptoms of latex sensitivity among OHCWs and patients.
      4. Refer OHCP with signs and symptoms suggestive of latex allergy to a physician to confirm diagnosis.
    2. Minimize the exposure of OHCPs with acute or chronic diseases to patients who have been diagnosed with a transmissible infectious disease.
      1. Consult with personal physician
        1. Determine if condition(s) might affect ability to safely perform duties.
    3. Minimize the exposure of patients to OHCPs who have been exposed to or have been diagnosed with an infectious disease (Tables 1, 2, 3, and 4).
      1. Restriction criteria
        1. Mode of transmission.
        2. Period of infectivity.
        3. Level of circulating viral burden.
        4. Level of risk for the transmission of a pathogen in association with a procedure.
      2. Procedure-related risk for bloodborne pathogen transmission.
Oral healthcare-associated procedures according to
the level of risk for bloodborne pathogen transmission.
  • Category I: Procedures with minimal risk of bloodborne pathogen transmission
    • History-taking
    • Extraoral physical examination
    • Intraoral examination
      • Including the use of a tongue depressor, mirror, explorer, or a periodontal probe
    • Routine preventive dental procedures - not requiring the administration of local anesthesia
      • Application of sealants or topical fluoride
      • Prophylaxis – not to include subgingival scaling with a hand instrument
      • Orthodontic procedures
      • Prosthetic procedures
        • Fabrication of complete dentures
      • Hands-off supervision of surgical procedures
  • Category II: Procedures for which bloodborne pathogen transmission is theoretically possible but unlikely
    • Dental procedures requiring the administration of local anesthesia
      • Operative, endodontic, and prosthetic procedures and periodontal scaling and root planning
        • Use of ultrasonic instruments greatly reduce or eliminate the risk of percutaneous injury to the provider
        • If significant physical force with hand instruments is anticipated to be necessary, scaling and root planning and other Category II procedures could reasonably classified as Category III
      • Minor surgical procedures
        • Simple tooth extraction not requiring excessive force
        • Soft tissue flap procedures
        • Minor soft tissue biopsy
        • Incision and drainage of an abscess
    • Insertion of, maintenance of, and drug administration into arterial and central venous lines
  • Category III: Procedures for which there is a definite risk of bloodborne pathogen transmission or that have been classified as “exposure prone”
    • General oral surgery
      • Surgical extractions
        • Removal of an erupted or unerupted tooth requiring elevation of a mucoperiosteal flap, removal of bone, or sectioning of tooth and suturing
      • Apicoectomy and root amputation
      • Periodontal curettage, gingivectomy, and mucogingival and osseous surgery
      • Alveoplasty and alveoectomy
      • Endosseous implant surgery
    • Open extensive head and neck surgery involving bone
    • Trauma surgery, including open head injuries, facial fracture reductions, and extensive soft issue trauma
    • Any open surgical procedure with a duration of more than 3 hours, probably necessitating glove change
3. Criteria for recommended clinical privileges:
  1. No evidence of having transmitted infection to patients.
  2. Obtained advice from an Expert Review Panel about continued practice.
  3. Follow-up twice a year to demonstrate the maintenance of an acceptable viral burden.
  4. Follow-up by personal physician with expertise in the management of infections with bloodborne pathogens.
  5. Consulted with an expert about and strictly adhere to optimal infection control procedures.
  6. Agreed to and signed a contract or letter from the Expert Review Panel that characterizes responsibilities.
