Protection Barriers!.. By Maricruz M.O

Introduction

Biosafety standards are intended to reduce the risk of transmission of microorganisms from recognized and unrecognized infection in Health Services accidents linked to exposure to blood and body fluids

Objectives

1. The accident prevention measures of health personnel is exposed to blood and other biological fluids.

2. The conduct to be followed an accident with exposure to these elements

Biosecurity principles

A) Universality: This involves considering the whole person can be infected. Also, consider all body fluids as potentially polluting. All staff should routinely follow standard precautions to prevent exposure of the skin and mucous membranes. These precautions should be applied to all people without exception or distinction

B) Use of barriers: Avoid direct exposure to blood and other body fluids potentially contaminated through the use of suitable materials that maybe brought in contact with them. The use of barriers (egg gloves) does not prevent accidents, exposure to these fluids, but decrease the consequences of that accident

C) Means of disposal of contaminated material: Includes the set of devices and procedures through which the materials used in patient care, are deposited and removed without risk of infection due to mishandling of these.

The dental practice infection can occur through the following mechanisms:

· Direct contact with infected substance (injury, blood, saliva).

· Direct contact with contaminated objects.

· Contamination by infected aerosols.

· Splashes of blood or saliva, nasopharyngeal secretions on the skin or mucosa or abraded healthy

Recommendations for the treatment of patients

1. Hand washing: Its purpose is to remove transient bacterial flora, reduce resident and avoid shipping. Therefore it is essential to wash hands before and after placement of the gloves.

2.Gloves: It is recommended for clinical examination non-sterile disposable gloves. For surgical procedures are recommended disposable sterilized. Reusable gloves should be thick and are used only for washing instruments

3. Masks: Them ask protects mainly then as al mucosa and prevents aerosol pollution caused by rotary instruments office.

4.Eye protection: Prevent eye injuries caused by particles projected on to the face of the operator, while protecting against infection where as many germs of normal oral flora are opportunistic pathogens.

5. Professional dress: Includes apron, bib and hat. It aims to prevent the introduction of microorganisms in to the work area. It also prevents contamination of street clothes during care in the office

6.Esterilizacion and disinfection of office, materials and: The local care should have walls and floors for easy cleaning, avoiding unnecessary wall or rough or porous materials that hinder industrial hygiene practice.

Disinfection: Is, in particular, the destruction of microorganisms of the instrumental work surfaces or by applying chemical agent at a concentration and time. We consider that disinfection includes only the removal of vegetative forms, does not ensure the destruction of bacterial spores.

To establish sterilization and disinfection strategies, we must consider factors such as:

ü contact time

ü concentration of the chemical

ü presence of organic matter or minerals on the surface of the instrument

ü Nature of the chemical agent in relation to its solubility in water

ü MO type, number and resistance to the agent

Conclusions

•Biosecurity and its rules must be respected by all for the sake of protecting their patients, their partners and their own health, so as to interrupt the chain of transmission of infectious agent and the disease itself.

•The challenge of dentistry today is among others to define a working system, equipment and methods that allow you to increase cover age and maintain the necessary and appropriate aseptic.

COMMENT

I chose this topic because as good health oral hygiene. Important processes such as digestion and communication, invite us to think about it. Unfortunately, some people ignore or overlook such important processes.

There are many factors involved in the maintenance of our mouth, for example, eating a balanced and nutritious diet, regular dental visits, attending conferences in the health centers to help provide prevention tools to improve health oral.
