Resumen
Las piezas dentales reutilizadas pueden albergar y transmitir virus como la hepatitis B (VHB) y el virus de la inmunodeficiencia humana (VIH) entre pacientes. La limpieza minuciosa y el tratamiento térmico son cruciales para prevenir los riesgos de contaminación cruzada.
Área de la Ciencia:
- Enfermedades infecciosas Enfermedades infecciosas.
- Salud pública dental de la salud pública.
- Ingeniería Biomédica Ingeniería Biomédica.
Sus antecedentes:
- El equipo dental reutilizado, especialmente las piezas de mano, plantea un riesgo potencial de contaminación cruzada.
- Los mecanismos internos pueden albergar materiales del paciente, lo que facilita la transmisión de patógenos, incluida la hepatitis B (VHB) y el virus de la inmunodeficiencia humana (VIH).
Objetivo del estudio:
- Para evaluar el riesgo de contaminación cruzada de las piezas de mano dentales reutilizadas y los ángulos de profilaxis.
- Para determinar si estos dispositivos pueden absorber y expulsar contaminantes derivados del paciente, incluido el ADN viral.
Principales métodos:
- Se llevaron a cabo ensayos de laboratorio y clínicos sobre nuevos ángulos de profilaxis y piezas manuales de alta velocidad.
- Se analizó el ADN específico humano, el ADN proviral del VIH y el ADN del VHB en muestras de dispositivos utilizados en pacientes y en contacto con sangre infectada.
- El bacteriófago phi X174 se utilizó como un virus modelo para probar la recuperación de partículas virales.
Principales resultados:
- Se detectó ADN humano y ADN del VIH dentro y expulsado de las piezas de mano durante los tratamientos de pacientes.
- El ADN del VHB se encontró en piezas de mano y mangueras conectadas después del contacto con sangre infectada.
- Las partículas infecciosas de bacteriófagos se recuperaron de los mecanismos internos, las mangueras y el spray de agua expulsado.
Conclusiones:
- Las piezas dentales reutilizadas y los ángulos de profilaxis pueden transmitir agentes infecciosos.
- Se recomienda una limpieza y un tratamiento térmico efectivos entre los pacientes para mitigar los riesgos de transmisión.
- Se necesita más investigación para abordar los riesgos de contaminación de las líneas de escape y de aire/agua.

01:18Handwashing I: Introduction and Types of Equipment
Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated.

01:30Cleaning, Sterilization, and Disinfection
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:26Standard Precaution
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.

01:17Transmission-based Precautions I: Contact, Enteric, and Droplets
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
