Study Notes
Infection Overview
- Infection involves the entry and multiplication of pathogens in a host; not all infections result in disease.
- Pathogens are microorganisms capable of causing diseases in humans.
Control of Infections
- Control aims to reduce disease incidence, prevalence, and the associated financial burden through continuous interventions.
- Objectives include:
- Decreasing the incidence and duration of diseases
- Minimizing effects of infections
Prevention Strategies
- Prevention measures aim to minimize the risk of infections by protecting individuals and hindering the spread of pathogens.
- Proactive strategies are essential for reducing exposure to infectious agents.
Infection Prevention and Control (IPC)
- IPC involves practices to prevent and control infections within healthcare settings.
- Critical for safeguarding healthcare workers and patients from various infectious agents.
Infection in Dental Technology Practice
- Infection transmission can occur in dental labs through pathogenic microorganisms during design and maintenance of dental devices.
- Infections can arise from handling dental prosthetics, which may be contaminated with bacteria, viruses, or fungi.
Importance of IPC Knowledge for Dental Technologists
- IPC knowledge is essential for dental technology students to ensure safe practices in dental environments.
- Knowledge of IPC protocols prevents cross-contamination and maintains sterile conditions necessary for patient safety.
- Key competencies include:
- Proper sterilization techniques to eliminate infection risks.
- Recognizing and managing risks related to sharps and bloodborne pathogens.
- Adopting IPC measures enhances overall public health by ensuring the safety of dental devices.
Main Sources of Infection in Dental Practice
- Contaminated Impressions and Materials: Impressions exposed to saliva or blood carry infectious agents.
- Cross-Contamination: Pathogen spread due to improper sterilization or handling in the lab.
- Improper Sterilization: Insufficient sterilization can leave surviving pathogens, posing infection risks to technicians and patients.
Mechanisms of Disease Transmission
Direct Contact
- Infections spread by physical contact, e.g., herpes simplex virus transmission.
Indirect Contact
- Transmission occurs through contaminated objects or surfaces, like doorknobs with norovirus.
Droplet Transmission
- Pathogens spread via respiratory droplets from coughing or sneezing, e.g., influenza virus.
Airborne Transmission
- Inhalation of airborne particles leads to diseases like tuberculosis.
Vector-borne Transmission
- Diseases transmitted by vectors, such as malaria by Anopheles mosquitoes.
Vehicle Transmission
- Pathogens spread through contaminated food, water, or medical devices, e.g., hepatitis A from food contamination.
Factors Influencing Transmission
- Host susceptibility influenced by factors such as age and immune status plays a significant role in infection risk.
