Study Notes
Infection and Disease Processes
- Infection is the entry and multiplication of microorganisms inside the host body.
- Infection control is a plan to protect individuals from infection and cross-infection.
- Disease is a pathological condition (abnormal condition) that manifests itself through symptoms.
- Acute describes immediate symptoms such as high fever and pain or distress.
- Chronic describes a condition present over a long time, often without an endpoint, such as chronic fatigue and anemia.
- Remission is a temporary or permanent cessation of a severe condition, such as a case of sinusitis or some stage of cancer.
Exogenous and Endogenous
- Exogenous causes are produced outside the body, such as illnesses arising from trauma, radiation, and hypothermia.
- Endogenous causes arise from within the body, such as infections, tumors, and congenital abnormalities.
Opportunistic and Nosocomial
- Opportunistic diseases or infections occur when body resistance is lowered, such as with fungal, bacterial, and viral infections.
- Nosocomial diseases are passed on from patient to patient in a healthcare setting, such as staphylococcal bacterial infections, MRSA, and others.
Pathogenic Microorganisms
- Pathogenic diseases are caused by microorganisms, including bacteria and viruses.
- Bacteria are microorganisms that require oxygen to live (aerobic) or don't require oxygen to live (non-aerobic).
- Some bacteria possess a capsule layer or a thick-walled spore.
Maintaining Knowledge and Skills
- Dental Health Care Practitioners (DHCP) should keep their knowledge and skills updated about infection control in the dental clinic setting.
Common Infectious Diseases of Concern to Dental Clinics
- Bacteria: Mycobacterium tuberculosis
- Fungi: Candida albicans
- Viruses: HIV, hepatitis B, C, herpes, influenza
Universal Standard Precautions
- Dental care settings carry a significant risk of infection transmission due to face-to-face communication, frequent contact with saliva, blood, and other body fluids, and handling of sharp instruments.
- All patients should be assumed to be carriers of infectious agents.
- Dental treatments involve the use of high-speed hand tools and rotary instruments, which, along with surgical instruments, produce aerosol droplets laden with virulent pathogens.
Chain of Infection
- Six elements are involved in the transmission of infectious diseases:
- Infectious agent: The microorganism causing the disease (bacteria, viruses, parasites)
- Reservoir: Place where the microorganism lives and multiplies (people, food, water, animals)
- Portal of exit: The pathway the microbe takes to leave the reservoir (coughing, sneezing, vomiting, urine/stool)
- Means of transmission: How the microbe moves from one person to another (contact, ingestion, inhalation)
- Portal of entry: Where the microbe enters a new host (mouth, eyes, nose, cuts)
- Susceptible host: A person who can get sick because their immune system is weak (elderly, people with weakened immune systems)
- Eliminating any one of these factors will prevent the transmission of infectious diseases.
Types of Germs
| Types of Germs | Where Germs Live | How Germs Get Out | How Germs Get Around | How Germs Get In |
|---|---|---|---|---|
| Bacteria | People, Food, Water, Animals | Coughing, Sneezing, Vomit, Blood, Urine/Stool | Contact, Ingestion, Inhalation | Mouth, Eyes, Nose, Cuts |
| Viruses | People, Food, Water, Animals | Coughing, Sneezing, Vomit, Blood | Contact, Ingestion, Inhalation | Mouth, Eyes, Nose, Cuts |
| Parasites | People, Food, Water, Animals | Coughing, Sneezing, Vomit, Blood, Urine/Stool | Contact, Ingestion, Inhalation | Mouth, Eyes, Nose, Cuts |
